Answer:

the electron volt (eV) is a unit of energy.

Answer:

The object's potential energy will be the same.

Explanation:

As long as the object hasn't been moved by itself, the potential energy will not change

Answer:

36W

Explanation:

Using P=VI

Where:

P = Power of the light bulb (in Watts W)

V = Voltage of the light bulb (in Volts V)

I = Current passing through the light bulb (in Ampere A)

P = 12V * 3A = 36W

When a body is thrown downwards, it falls freely under gravity.

The question is incomplete as the values are missing but I will try to help you the much I can. We must note that the acceleration of a body refers to the rate at which its velocity changes per unit time.

When an object is thrown down from a height. It gains speed due to acceleration due to gravity which acts on the body as it falls freely.

The moon rotates round Earth, we see it as crescent moon.Hence, I agree with the initial student.

Generally, due to the fact he rightly stated  that the positions of the Earth, Sun and moon continues on altering consistently due to the motion of moon round Earth.

Now, when the moon comes in between the Sun and the Earth about 1/2 component of the moon receives sunlight.

Similarly, as the moon rotates round Earth, a Earth will see the Sun-rays on the Moon coming from distinct angles and when solely a small element of the moon is illuminated via sunlight, we see it as crescent moon.

Answer:

By friction,by contact,by Electrostatic induction

Explanation:

By friction:This is the process whereby electric charges are produced when two surfaces move over another

By Contact :This is when energy is produced when two bodies come in contact with each other

By electrostatic induction: When a charged object is brought closer to another object (not touched), the original object doesn't lose any charge and the other object gets charged.

The value of the charge will be 7.69 ×10⁻⁵ C. When the matter is subjected to an electromagnetic field, it acquires an electric charge, which causes it to experience a force.

Electric potential is the amount of work needed to move a unit charge from a point to a specific point against an electric field.

The given data in the problem is;

[tex]\rm E_p[/tex] is the electric potential energy = 0. 025 J

V is the electric potential = 325 V

Q is the charge =?

Electric potential energy is the product of the charge and the voltage. So the value of the charge is given as;

[tex]\rm E_p= Q \times V \\\\ \rm Q= \frac{ E_p}{V} \\\\ Q= \frac{ 0.025}{325} \\\\ \rm Q = 7.69 \times 10^{-5} \ C[/tex]

Hence the value of the charge will be 7.69 ×10⁻⁵ C.

These two objects are experienced different forces and the object which experiences the same change in momentum but over a shorter period of time will experience more force than the other object.

To know more about the dependance of force on momentum and time, we need to know more about force and how it works.

Thus, we can conclude that between these two objects, one, who experiences the same change in momentum for shorter period of time, will experience more force than other.

A car travelling at a speed of 45 m/h takes 20 minutes to reach its destination.

We have to find the distance travelled by the car .

Changing the unit of time into hour

Time = 20/60 hour

Time = 2/3 hour

Now, let's calculate the distance travelled by the car .

[tex] \bf \: Distance \: travelled \: = Speed \: \times Time[/tex]

Put the value we get

[tex] \sf \dashrightarrow \ \: Distance \: travelled \: = 45 \times \frac{2}{3} \\ \\ \sf \dashrightarrow \ \: Distance \: travelled \: = \cancel{45} \: \times \frac{2}{ \cancel3} \\ \\ \sf \dashrightarrow \ \: Distance \: travelled \: = 15 \times 2 \\ \\ \sf \dashrightarrow \ \: Distance \: travelled \: = 30km \: [/tex]

So, the distance travelled by the car is 30Km .

The car has travelled a distance of 15 m

Since distance, d = vt where

Now, the car travels at a speed of 45 m/h in 20 minutes.

So,

Since d = vt,

substituting the values of the variables into the equation, we have

d = vt

d = 0.75 m/min × 20 min

d = 15 m

So, the car has travelled a distance of 15 m

The mass of a rolling ball with kinetic energy of 18 joules and velocity of 3m/s is 4kg.

Explanation:

HOW TO CALCULATE MASS?

The mass of a moving object can be calculated by using the following expression:

K.E = ½ mv²

Where;

K.E = kinetic energy (Joules)

m = mass (kg)

v = velocity (m/s)

According to this question, rolling ball has 18 joules of kinetic energy and is rolling at 3m/s. The mass is calculated as follows:

18 = ½ × m × 3²

18 = ½ × 9m

36 = 9m

m = 4kg

Therefore, the mass of a rolling ball with kinetic energy of 18 joules and velocity of 3m/s is 4kg.
