Answer:

Gravitational force is the force that attracts objects towards each other. Two factors that affect the gravitational force between objects are the mass of the two objects and the distance between

Explanation:

Gravity is what pulls us towards the Earth if we were to jump into the air, so it is the force that pulls things towards other things. The bigger the objects are the more gravity they have, so a planet has more gravity than say, an apple. Distance between objects also makes their gravity change, so the Earth's pull on the moon is different than the Earth's pull on the sun.

Hopefully this helps- let me know if you have any questions!

The dynamic load rating of the ball bearing is 2,200,000 N.

The dynamic load rating (C) of the ball bearing can be calculated using the following formula,

C = P((L/10)^p)

where P is the equivalent radial load, L is the expected life of the bearing, and p is a constant determined by the type of bearing (for ball bearings, p = 3).

Given that the stationary equivalent radial load is 3 kN for 10% of the time, 2 kN for 20% of the time, 1 kN for 30% of the time, and no load for the remaining time,

Time duration for 3 kN load = 0.1 * L = 2 x 10^6 revolutions

Time duration for 2 kN load = 0.2 * L = 4 x 10^6 revolutions

Time duration for 1 kN load = 0.3 * L = 6 x 10^6 revolutions

Time duration for no load = 0.4 * L = 8 x 10^6 revolutions

The total time duration for all loads is equal to the expected life of the bearing, which is given as 20 x 10^6 revolutions.

Substituting the values in the formula,

C = 3((2 x 10^6/10)^3) + 2((4 x 10^6/10)^3) + 1((6 x 10^6/10)^3)

C = 3(200,000) + 2(400,000) + 1(600,000)

C = 2,200,000 N

Answer:

• Bring another magnet wound with a copper wire, at the top of the fixed magnet. Here EMF will be generated by mutual induction

Explanation:

\(.\)

Bringing another coil close to the fixed magnet will induce an emf through a process called mutual induction.

An emf is induced when there is relative motion of a conductor placed in a magnetic field.

When the current in one coil is changed by contact of anothe coil, we call it mutual induction.

Thus, if the magnetic field is constant and the magnet fixed, bringing another coil close to the fixed magnet will induce an emf through a process called mutual induction.

The pendulum will be moving at approximately 0.754 m/s when it passes through the lowest point of its swing.

To determine the speed of the pendulum when it passes through the lowest point of its swing, we can use the principle of conservation of mechanical energy.

At the highest point (2.9 cm above the resting position), the pendulum has gravitational potential energy. As it swings down, this potential energy is converted into kinetic energy, given by the equation:

Potential Energy (PE) = Kinetic Energy (KE)

The highest point's potential energy is given by:

PE = mgh

Where:

m = pendulum mass (4.0 kg).

g = acceleration due to gravity (9.8 m/s^2)

h = height above the resting position (2.9 cm = 0.029 m)

Substituting the values, we have:

PE = 4.0 kg * 9.8 m/s^2 * 0.029 m = 1.1356 J

Since energy is conserved, this potential energy will be completely converted into kinetic energy at the lowest point. Thus, the kinetic energy is also 1.1356 J:

KE = 1.1356 J

The following equation gives the kinetic energy:

KE = (1/2)mv^2

Where:

m = pendulum mass (4.0 kg).

v = velocity of the pendulum at the lowest point

Rearranging the equation to solve for v:

v^2 = (2KE) / m

v^2 = (2 * 1.1356 J) / 4.0 kg

v^2 = 0.5678 m^2/s^2

Taking the square root of both sides results in the following:

v ≈ 0.754 m/s

Therefore, the pendulum will be moving at approximately 0.754 m/s when it passes through the lowest point of its swing.

Answer:

Below are a few examples of real-life applications of physics that happen around you every day, that should make it easier to understand the various concepts: cutting food, fruits and vegetables.

Explanation:

The total charge in the circuit is 240 microcoulombs.

To calculate the total charge in a series circuit with capacitors, we need to use the formula Q = CV, where Q represents the charge, C is the capacitance, and V is the voltage.

In this case, we have three capacitors connected in series with capacitances of 4 μF, 3 μF, and 2 μF, respectively. The voltage across the circuit is 260 V.

To find the total capacitance (C_total) in a series circuit, we use the reciprocal rule: 1/C_total = 1/C1 + 1/C2 + 1/C3. Plugging in the values, we get 1/C_total = 1/4 + 1/3 + 1/2.

Simplifying this equation gives us 1/C_total = (3 + 4 + 6)/12 = 13/12. Taking the reciprocal, we find C_total = 12/13 μF.

Now, we can calculate the total charge (Q_total) using Q = C_total × V. Substituting the values, we get Q_total = (12/13) μF × 260 V.

Calculating the numerical value, Q_total = (12/13) × 260 = 240 μC (microcoulombs).

Elements are arranged on the periodic table in terms of valence electrons based on their atomic number and electron configuration.

1. Elements are arranged on the periodic table in terms of valence electrons based on their atomic number and electron configuration. The valence electrons are the outermost electrons in an atom's electron shell, and they are crucial in determining the chemical properties and reactivity of elements.

2. Evidence from data tables can be shown by examining the electron configuration and the group and period numbers of various elements on the periodic table. Here is a simplified example:

Element   | Electron Configuration | Group | Period |

--------------------------------------------

Hydrogen  | 1s^1                              | 1     | 1      |

Lithium       | [He] 2s^1                     | 1     | 2      |

Carbon       | [He] 2s^2 2p^2          | 14    | 2      |

Oxygen      | [He] 2s^2 2p^4          | 16    | 2      |

Neon          | [He] 2s^2 2p^6          | 18    | 2      |

--------------------------------------------

3. The evidence from the data table supports the claim that the arrangement of elements on the periodic table is based on valence electrons.

- Group Trend: Elements within the same group (vertical columns) share the same number of valence electrons. In the example table, Hydrogen, Lithium, and Neon are all in Group 1, indicating they have 1 valence electron.

- Period Trend: Elements within the same period (horizontal rows) have the same number of electron shells. In the example table, Hydrogen and Lithium are in Period 1, indicating they have their valence electron in the first energy level. Carbon, Oxygen, and Neon are in Period 2, indicating they have their valence electrons in the second energy level.

By examining the electron configurations, group numbers, and period numbers, we can clearly see the trends and patterns in the number of valence electrons for both groups and periods on the periodic table. This evidence supports the claim that the arrangement of elements on the periodic table is based on their valence electrons, which play a crucial role in determining their chemical behavior and properties.

The method to separate a mixture of sugar, sand, and bits of iron is through magnetic separation, filtration and evaporation.

First the bits of iron is separated from the mixture by using magnetic separation method. Since the bits of iron are susceptible to magnet force, it is separated from the mixture by placing a magnet in the mixture, so that the bits of iron stick to the magnet.

Next, pour water in the mixture. Since sugar is highly soluble in water, it will be dissolved in water. Then the solution is separated from the mixture using a filter. Now sand is separated. To separate sugar from water, it is boiled until all the water evaporates and only sugar remains. Thus all three items are separated from each other.

Therefore, the method to separate a mixture of sugar, sand, and bits of iron is through magnetic separation, filtration and evaporation.

A spark detector cannot detect beta radiation because beta particles are much less ionising than alpha particles.

A spark detector is a simple device which monitors the infrared light within the field of view of a special sensor which detects light in the infrared range.

The spark detection system is designed to protect industrial processes by helping reduce the risk of ignition sources such as burning embers from reaching protected equipment.

A spark detection system consists of a detector that identifies dangerous particles (ignition sources) in process flows.

The spark detector works by alpha particles ionising atoms in the air near a wire mesh. A large potential difference creates a spark when the air near the wire mesh is ionised.

Thus,  we can conclude the following as a reason why a spark detector cannot detect beta radiation.

Answer:

The first law, also called the law of inertia, was pioneered by Galileo. This was quite a conceptual leap because it was not possible in Galileo's time to observe a moving object without at least some frictional forces dragging against the motion. In fact, for over a thousand years before Galileo, educated individuals believed Aristotle's formulation that, wherever there is motion, there is an external force producing that motion.

The second law, $ f(t)=m\,a(t)$ , actually implies the first law, since when $ f(t)=0$ (no applied force), the acceleration $ a(t)$ is zero, implying a constant velocity $ v(t)$ . (The velocity is simply the integral with respect to time of $ a(t)={\dot v}(t)$ .)

Newton's third law implies conservation of momentum [138]. It can also be seen as following from the second law: When one object ``pushes'' a second object at some (massless) point of contact using an applied force, there must be an equal and opposite force from the second object that cancels the applied force. Otherwise, there would be a nonzero net force on a massless point which, by the second law, would accelerate the point of contact by an infinite amount.

Explanation:

Answer:

Hooke's law states that the applied force F equals a constant k times the displacement or change in length x, or F = kx. ... Hooke's law describes the elastic properties of materials only in the range in which the force and displacement are proportional.

Explanation:

At point P, the electric potential is 0. This is due to the fact that the positive and as a result, at point P, their electric potentials are cancelled.

Positive and negative electrical charges are referred to as opposite forms of charge. A positively charged object will draw a negatively charged object, in accordance with our core concept of charge interaction.

We can apply the following equation to find the electric potential at point P: V = kQ/r1 - kQ/r2.

where:

k = Coulomb's constant (9 x 10⁹ N m²/C²),Q = magnitude of the charge (3.3 μC = 3.3 x 10⁻⁶ C), r1 = distance from the positive charge to point P (a = 0.35 m), r2 = distance from the negative charge to point P (a = 0.35 m)

Using these values, we can calculate the potential at point P as follows:

V = (9 x 10⁹ N m²/C²) * (3.3 x 10⁻⁶  C) / (0.35 m) - (9 x 10⁹ N m²/C²) * (3.3 x 10⁻⁶ C) / (0.35 m)

V = 0.
