Answer:

The new force becomes 3 times of the initial force.

Explanation:

Let q₁ and q₂ are two charged particles. The force between them is given by :

\(F=\dfrac{kq_1q_2}{r^2}\ ......(1)\)

If \(q_1'=\dfrac{q_1}{4}\)

and

\(q_2'=3q_2\)

Also, r' = r/2

New force,

\(F'=\dfrac{kq_1'q_2'}{r'^2}\)

Putting all the above values,

\(F'=\dfrac{k\dfrac{q_1}{4}3q_2}{(r/2)^2}\\\\F'=3\times \dfrac{kq_1q_2}{r^2}\\\\F'=3F\)

So, the new force becomes 3 times of the initial force.

Explanation:

The two parallel branches with current loads of 20A and 25A and voltage 240V have total current as 45A.

The total current (I) of the parallel circuit is equal to the sum of the individual branch currents.

Total current (I) = \(I1 + I2\)

From, question we have  \(I1\) = 20A and \(I2\) = 25A

Hence, I = 20+25

I = 45A

Therefore, total current is 45A

A parallel circuit has more than one path for current flow. The number of current paths is determined by the number of load resistors connected in parallel.

The total current in a circuit is the current flowing in one conductor connected in parallel (such as the current from an electromotive force).

The correct answers are a. Made up of multiple platters on a single spindle. d. Use magnets/magnetic fields to erase data.

Conventional hard disk drives (HDDs) consist of multiple platters that are stacked on a single spindle. These platters are coated with a magnetic material, typically iron oxide or a similar ferrous material. The data on the platters is read and written using magnetic heads that move over the surface of the platters. The magnetic heads utilize magnets and magnetic fields to manipulate the magnetic particles on the platters, representing the data. The orientation of the magnetic particles determines the stored data, and the heads can magnetically change their direction to write or erase data.

It's important to note that conventional HDDs do not use LED lasers to manipulate data. Instead, they rely on the magnetic properties of the platters and the movement of the magnetic heads to access and modify the data. The use of magnets and magnetic fields is integral to the functioning of conventional HDDs, allowing for the reading, writing, and erasing of data.

The fraction of the original current that travels path b depends on the resistances of the two branches a and b, and the voltage across each branch.

The resistance of a conductor is proportional to the current flowing through it, and the voltage across a conductor is proportional to the power being supplied to it.

Ohm's law states that the voltage across a conductor is proportional to the current flowing through it and the resistance of the conductor, V = IR.

Therefore, the fraction of the original current that travels path b can be determined by the ratio of the resistance of path b to the total resistance of both paths a and b, and the voltage across path b to the total voltage across both paths.

The fraction of current that travels path b = (Resistance of path b / Total resistance) * (Voltage across path b / Total voltage)

In other words, the fraction of the original current that travels path b is determined by the impedance of path b relative to the impedance of both paths combined.

The new electrostatic force will be 384 units.  

The electrostatic force of attraction between two charges \(q_{1} \\\)(charge of object 1)  and \(q_{2}\)(charge of object 2) separated by a distance d is given by

\(F = \frac{q_{1} q_{2}}{4\pi E_{0} d^{2} } \\\)

\(E_{0} = 8.854 * 10^{-12} C^{2} N^{-1} m^{-1}\) is the permittivity of free space.

Initially, we have,

\(\frac{q_{1} q_{2}}{4\pi E_{0} d^{2} } =F_{1} = 8 units\)  

Now, if the charge of object 1 is multiplied by 1, the charge of object 2 is multiplied by 3, and the distance separating objects 1 and 2 is divided by 4, we have, \(q_{1} =q_{1}, q_{2} =3q_{2} , d=\frac{d}{4}\).

The new electrostatic force will be,

\(F_{2} = \frac{q_{1} 3q_{2}}{4\pi E_{0} (\frac{d}{4} )^{2} } \\\\\) units.

We have, \(F_{1} = 8 units= \frac{q_{1} q_{2}}{4\pi E_{0} d^{2} } \\\)

Hence,

\(F_{2} =\frac{8*3}{(\frac{1}{4}) ^{2} } units= 384 units.\)

The energy needed to heat the water and the copper tank to 55°C is 25,083,080 J.

Q = mCΔT

m = 150 kg (mass of water)

C = 4.18 J/g°C (specific heat capacity of water)

ΔT = 55°C - 15°C = 40°C (change in temperature)

Using the formula, we get:

\(Q_{water}\) = mCΔT

\(Q_{water}\) = (150 kg) x (4.18 J/g°C) x (40°C)

\(Q_{water}\) = 25,080,000 J

m = 20 kg (mass of tank)

C = 0.385 J/g°C (specific heat capacity of copper)

ΔT = 55°C - 15°C = 40°C (change in temperature)

Using the formula, we get:

\(Q_{tank}\) = mCΔT

\(Q_{tank}\) = (20 kg) x (0.385 J/g°C) x (40°C)

\(Q_{tank}\)= 3080 J

Finally, we can add the two energies together to get the total energy needed:

\(Q_{total}\) = \(Q_{water}\) \(+\) \(Q_{tank}\)

\(Q_{total}\) \(= 25,080,000 J + 3080 J\)

\(Q_{total}\) \(= 25,083,080 J\)

The temperature of the joint between the steel rod and the aluminum rod will be somewhere between the temperature of the ice and the boiling water, but it cannot be determined exactly without knowing the specific thermal conductivity and other properties of the materials involved.

The temperature of the joint will depend on how quickly heat is conducted from the hot end of the aluminum rod to the cold end of the steel rod. Both rods will conduct heat, but at different rates due to their different thermal conductivities. The steel rod will conduct heat more slowly than the aluminum rod because steel has a lower thermal conductivity than aluminum.

Without more information about the specific properties of the materials and the conditions of the experiment, it is not possible to determine the exact temperature of the joint. However, it can be concluded that the temperature will be somewhere between the freezing point of water and the boiling point of water.

For the honeybee that circles a field looking for a flower upon which to land, we have:

a) The tangential velocity is 10.01 m/s.

b) The centripetal acceleration is 40.1 m/s².

c) The centripetal force is 1.60 N.

a) The tangential velocity can be calculated as follows:

\( v = \omega r = \frac{2\pi r}{T} \)  (1)

Where:

r: is the radius of the circle = 2.5 m

ω: is the angular velocity = 2π/T

T: is the period = 1.57 s

By entering the above values into equation (1), we have:

\( v = \frac{2\pi r}{T} = \frac{2\pi 2.5 m}{1.57 s} = 10.01 m/s \)  

Hence, the tangential velocity is 10.01 m/s.

b) The centripetal acceleration is related to the tangential velocity as follows:

\( a_{c} = \frac{v^{2}}{r} = \frac{(10.01 m/s)^{2}}{2.5 m} = 40.1 m/s^{2} \)

Therefore, the centripetal acceleration is 40.1 m/s².

c) The centripetal force is given by:

\( F = ma_{c} \)

Where:

m: is the honeybee's mass = 0.04 kg

\( F = ma_{c} = 0.04 kg*40.1 m/s^{2} = 1.60 N \)

Hence, the centripetal force is 1.60 N.
