Have you ever been in a bus, a train, or a car ?
What happens to you when it stops suddenly ?
A body in motion continues in motion unless
an external force acts on it and makes it stop.
Amy's body keeps moving forward when the train stops.
She pitches forward, and if she doesn't reach out and grab
a seat or a seated person, she may lose her footing and fall
on her face.
Choice - 'A' is a very good explanation.
The other choices aren't.
'C' is a good hunch, but it only applies to her feet.
The rest of her keeps going.
'D' is nonsense. There are no mysterious forces of
'repulsion' or 'attraction' on the train.
You can start with a recycling project , it can solve any problems including saving animals, giving clean water, and cleaner environment ofcourse
Answer:
Explanation:
decrease in energy of the transferred charge
= Voltage x charge
= 2.86 x 10⁹ x 23.1
= 66.067 x 10⁹ J
the final speed of the automobile be V
1/2 m v² = 66.067 x 10⁹
v² = 66.067 x 10⁹ x 2 / 1519
= .08698 x10⁹
= 87 x 10⁶
v = 9.32 x 10³ m / s
