For motion along a straight line it ______ possible for speed to be constant while acceleration is not zero.

Answer:

The weight of the 225-kg space probe on the moon is 364.5 N (newtons).

Explanation:

To calculate the weight of the space probe on the moon, we can use the formula:

weight = mass x acceleration due to gravity

where mass is given as 225 kg and acceleration due to gravity on the moon is 1.62 m/s^2.

weight = 225 kg x 1.62 m/s^2

weight = 364.5 N

Therefore, the weight of the 225-kg space probe on the moon is 364.5 N (newtons).

Vernier calipers are used for taking very small measurements such as the diameter of a wire.

It is used to provide a precision to 0.1mm or 0.01cm. This is a precision to two decimal places in centimeters. This means that if the caliper measures a value of say xcm, then with its level of precision, the measurement is actually likely to be around

(x ± 0.01) cm

The option that fits best is 1.03cm since that is the only option in 2 decimal places and close to the measured value.

Answer:

Its A I'm 99.9% sure

Explanation:

It is FALSE that the proportionality dependence of the current (i) through any conductor to the voltage (v) across it and its resistance (r) is true for all conductors regardless of temperature.

When the conductors have a higher temperature, the molecules in the conductor will be more crowded and the result is the resistance of the conductor will rise. Hence, the current flowing through the conductor will decrease in the same voltage.

In the lower temperature, the resistance of the conductor will decrease and lead to more current flowing through the conductor in the same voltage.

Thus, the conductor temperature has an effect on its resistance.

The magnetic energy per unit length inside the wire is µ₀ I² / 16π.

We need to find the magnetic energy per unit length inside a wire with radius R which carries a total current I. The wire is made of nonmagnetic material, with the current distributed uniformly over its cross section. Magnetic energy is the energy of magnetic fields. The energy density of a magnetic field is given by;

\($$u = \frac{B^2}{2\mu_0}$$\)

Where B is the magnetic field and μ0 is the permeability of free space. The magnetic field due to a wire carrying a current I is given by the Biot-Savart law as;

\($$B = \frac{\mu_0 I}{2\pi r}$$\)

Where r is the distance from the wire. Substituting the above equation into the first equation gives us;

\($$u = \frac{1}{2}\frac{\mu_0 I^2}{4\pi^2 r^2}\pi r^2 = \frac{\mu_0 I^2}{8\pi r}$$\)

Thus, the magnetic energy per unit length inside the wire is given by;

\($$\frac{u}{\Delta l} = \frac{\mu_0 I^2}{8\pi r}\Delta l$$\)

\($$\frac{u}{\Delta l} = \frac{\mu_0 I^2}{8\pi R}$$\)

Therefore, the magnetic energy per unit length inside the wire is µ₀ I² / 16π.

Therefore, the magnetic energy per unit length inside the wire is given by µ₀ I² / 16π.

Answer: 5.4 seconds

Explanation:

The time taken to stop the bicycle is 5.4 seconds. The final velocity is zero. Then, the distance travelled by the bicycle is 36.45 m.

Acceleration is a physical quantity that, measures the rate of change in velocity. It is a vector quantity thus having both magnitude and direction. It can be defines as the ratio of change in velocity to the change in time.

Given initial velocity = 13.5 m/s

final velocity is zero since the bicycle is stopping.

then Δt = Δv/a

Δt = 13.5 m/s/ 2.50 m/s² = 5.4 seconds.

Hence, the bicycle will take 5.4 s to complete stop.

The distance covered within this time can be determined using the equation as follows:

s = ut + 1/2 at²

where u is the initial velocity

s =  (13 m/s × 5.4 s) + (-2.50 m/s² ×5.4 s ×5.4 s) = 36.4 m.

Therefore, the bicycle will travel up to 36.4 m before stopping.

The work done on a particle with mass m to accelerate it from rest to a speed of 0.906c is approximately 0.428mc² and  to accelerate it from a speed of 0.906c to a speed of 0.986c is approximately 0.058mc².

What is particle with mass?

A particle with mass refers to a fundamental or elementary particle that possesses mass. In the context of particle physics, elementary particles are the building blocks of matter and are considered to be point-like entities with no internal structure.

There are several elementary particles known to have mass, including:

Quarks: Quarks are elementary particles that combine to form protons and neutrons, which are the building blocks of atomic nuclei. Quarks have different flavors (up, down, charm, strange, top, and bottom) and carry fractional electric charges.

Leptons: Leptons are another class of elementary particles that include electrons, muons, and taus, along with their corresponding neutrinos. Electrons, for example, are negatively charged particles that orbit around the nucleus of an atom.

To calculate the work done on a particle to accelerate it, we can use the relativistic equation for kinetic energy:

K = (γ - 1)mc²

where K is the kinetic energy, γ is the Lorentz factor given by γ = 1/√(1 - (v/c)²), m is the mass of the particle, and c is the speed of light.

For the first scenario, when accelerating from rest to a speed of 0.906c:

γ₁ = 1/√(1 - (0.906c/c)²) ≈ 2.897

The work done is then given by:

W₁ = K₁ = (γ₁ - 1)mc² ≈ 1.897mc² ≈ 0.428mc²

Therefore, the work done to accelerate the particle to 0.906c is approximately 0.428 times mc².

For the second scenario, when accelerating from a speed of 0.906c to a speed of 0.986c:

γ₂ = 1/√(1 - (0.986c/c)²) ≈ 3.196

The work done is again given by:

W₂ = K₂ = (γ₂ - 1)mc² ≈ 2.196mc² ≈ 0.058mc²

Therefore, the work done to accelerate the particle from 0.906c to 0.986c is approximately 0.058 times mc².

In summary, in quantum mechanics, a particle's energy can be less than the potential energy due to the quantization of energy levels and the possibility of superposition. This is in contrast to classical mechanics, where the total energy of a particle cannot be less than the potential energy.

In quantum mechanics, it is indeed possible for the energy E of a particle to be less than the potential energy, while in classical mechanics, this condition is not possible. This discrepancy arises due to the fundamental differences in the way energy is defined and understood in these two theories.

In classical mechanics, the energy of a particle is the sum of its kinetic energy and potential energy. Kinetic energy is determined by the particle's mass and velocity, while potential energy is determined by its position and the forces acting upon it. The total energy of the particle remains constant, and it cannot be less than the potential energy.

However, in quantum mechanics, the energy of a particle is quantized. This means that it can only take on specific discrete values called energy levels. These energy levels are determined by the particle's wave function and are related to its position, momentum, and other properties. The lowest energy level is known as the ground state.

In quantum mechanics, a particle can exist in a superposition of energy states, meaning it can simultaneously possess different energy levels with different probabilities. This allows for the possibility of the particle having an energy E that is less than the potential energy. The probability distribution of the particle's energy levels is described by its wave function.

To illustrate this concept, let's consider the example of an electron in an atom. The electron can occupy different energy levels around the nucleus. When it is in the ground state, it has the lowest energy level and is closest to the nucleus. However, it can also exist in higher energy levels, farther away from the nucleus. These higher energy levels have a higher potential energy, but due to the wave-like nature of electrons in quantum mechanics, the electron can still have a lower total energy than the potential energy.

Hi there!

For an object to have a constant velocity, the SUM of the forces must equal 0. This means that the forces are balanced.

When a car is accelerating downhill, it is experiencing a force due to gravity of F = MgsinФ.

In order to balance the forces, there must be an equal and OPPOSITE force acting on the object. This would be a force of kinetic friction.

Thus:

∑F = -F (Kinetic Friction) + MgsinФ

0 = -F (Kinetic Friction) + MgsinФ

MgsinФ = F (Kinetic Friction)

Thus, the force of Kinetic Friction = -3674 N

Beta decay forms a daughter nucleus with a different atomic number than the parent nucleus. The correct answer is option B.

A nucleus loses an electron when it emits the beta particles. The parent and daughter nuclei share the same atomic mass because the mass of an electron is so much less than that of a proton or neutron. The offspring nucleus has an atomic number that is one higher than the parent nucleus.

There are mainly two types of beta decay: beta plus (positron decay) and beta minus (electron decay). The daughter atomic number reduces by one after beta plus decay (the nucleus loses one positive charge) and rises by one after beta minus decay (the nucleus loses one negative charge).
