gaining thermal energy in form of heat
Explanation:
When the thermal energy of a matter is increasing, it will directly increase the kinetic energy of the matter.
- Temperature changes causes the average kinetic energy of molecules to increase or decrease.
- If the kinetic energies of particles are increasing, the temperature must have been on rise.
- Increase in temperature causes molecules to start vibrating and moving about.
- The gain more energy that helps them to move away from their original position

Given:
Object in circular motion 25 m/s
1 second to go quarter circle
Required:
Centripetal acceleration:
Solution:
Acceleration = v2/r
Where v is the velocity and r is
the radian
Substituting the values into the
equation,
Acceleration = v2/r = (25
m/s)2/(4*pi/180) = 8952.47 m2/s2
Answer:
n = 4.35 x 10¹⁹
Explanation:
Given that
Voltage V= 12 V
Power rating of headlights = 41.8 W
We know that headlights of the car is connected in parallel connection.
We know that
Power = Current x Voltage
P = V I
I=3.48 A
Therefore the total current will be
I'= 3.48 + 3.48 A
I = 6.96 A
We know that
Charge = Current x time
q= I' t
q= 6.96 x 1
q= 6.96 C
The charge on electron ,e= 1.6 x 10⁻¹⁹
q= n e
n=Number of electron
n = 4.35 x 10¹⁹
Answer: thermal
Explanation:
Moving particles transfer thermal energy through a fluid by forming convection currents.
