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.

As we know that work done due a force F is given by formula
here F = applied force due to which work is done
d = displacement of object
now here we will have
W = 588 J
d = 1.4 m
now we can find force by above formula
So applied force by milkman is F = 420 N
Answer:
I am pretty sure that the answer would be a peer reviewed article.
Explanation:
I saw this because, an encyclopedia, published scientific journal, and a lab journal used in the original experiment, are all reliable sources of information.
Answer:
(A) Original velocity will be 7.244 m /sec
(B) Acceleration will be 
Explanation:
We have given distance covers by truck s = 40 m
Time taken by truck to cover this distance t = 7.45 sec
Final velocity v = 3.50 sec
According to second equation of motion
-----eqn 1
According to first equation of motion
v = u + at
So 
-----eqn2
Solving equation 1 and 2
a =
And u = 7.244 m /sec
(A) Original velocity will be 7.244 m /sec
(B) Acceleration will be
The things that determine the amount of an object's gravitational potential energy are ...
-- mass of the object
-- gravitational acceleration in the place where the object is
-- height of the object above the ground or the floor
A). <em>a slice of bread; </em> No. It's still a slice of bread even if it's on the ground.
B. <em>A compressed spring; </em> No. It's still a compressed spring even if it's on the ground.
C. <em>An apple on a tree</em>; <em>Yes !</em> It can't be an apple on a tree if it's on the ground.
D. <em>A stretched bow string</em>; <em>No.</em> It's still a stretched bowstring even if it's on the ground.
