I am not sure exactly maybe u should ask a friend
Answer:
B
Explanation:
momentum = mass * velocity
velocity = initial speed + acceleration * time where initial speed =0, acceleration = 9.81, time = 4
Answer:
example of kinetic theory include brownian motion the random movement of the particles because the consolation with the air molecules and how gas is behave boiling and j l also this cyclone explain how temperature affects the
Answer:
K.E = 463.04 k J
P = 23.14 Watt
Explanation:
given,
mass of automobile = 1200 kg
velocity = 50 km/h
= 50 × 0.278
= 13.9 m/s
kinetic energy = 
=
K.E = 115.93 k J
vehicle accelerated to velocity = 100 km/h
= 100 × 0.2778
= 27.78 m/s
kinetic energy = 
=
K.E = 463.04 k J
work done = change in kinetic energy
= 463.04 - 115.93
= 347.11 J
Power = 
Power =
P = 23.14 Watt
While a car is running, the alternator provides current to the battery and recharges it. Reduction reaction occurs at the anode of a lead-storage battery during this process .
The Lead-acid battery or lead-storage battery is one of the oldest types of rechargeable batteries.
Lead-storage batteries can be classified as secondary batteries. The chemical reactions that occur in secondary cells are reversible. The chemical process of extracting current from a secondary battery (forward reaction) is called discharging. The method of regenerating active material is called charging.
While recharging, the automobile battery functions like an electrolytic cell. The energy required to drive the recharging comes from an external source, such as an engine of a car. While charging reduction takes place at anode and while discharging oxidation takes place at anode.
