Answer:
c
Explanation:
The car travels with centripetal acceleration which is directed to the center of the circle but the velocity is changing since the car faces different direction as it travels in the circular direction. When the friction is zero between the tires of the car and the road, it will continue in the direction of its tangential velocity which will be along a straight-line path in its original direction.
The correct answer to the question is D) 6 joules.
EXPLANATION:
As per the question, four measurements are given i.e 24 m/s, 60 mg, 15 L and 6 J.
We are asked to determine the measurement which corresponds to energy.
Energy is measured in various units like joule, erg, electron volt etc.
Joule is the unit of energy in S.I system.
Hence, the correct measurement which corresponds to energy is 6 joules.
All other measurements like 24 m/s, 60 mg and 15 L are not the measurements of energy. These are the measurements of speed, mass and volume respectively.
Answer:
in parallel combination : potential difference between two terminal of resistors are always constant. ... hence, potential difference ( voltage ) must be same across each resistor .
