Answer:
B is correct
Explanation:
Battery contains sulfuric acid H2SO4. As the battery cools and eats with the running of the motor, hydrogen gasses is released from electrolytic reactions and escapes through the vents. it mixes with other particulates. The mixtures react at the electrical terminals of the battery and corrosion is formed.
Corrosion can be prevented by the addition of anti corrosion gel. It can also be removed by scrubbing the terminals with a hard brush
F=ma
8480=26.5m
m=8480/26.5
m=320
The mass of the cart is 320kg.
They don't have free electrons moving around (delocalised electrons) so they can't conduct electricity which gives them the property of good insulators.
Answer:

Explanation:
As we know by energy conservation
All its kinetic energy will convert into thermal energy to raise its temperature

now divide both sides by mass of the object

so change in temperature is given as
