Answer:
2m/s
Explanation:
The formula for speed is [ s = d/t ].
s = 8/4
s = 2m/s
Best of Luck!
Then the the speed of the molecules also increase
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.
Answer:
new energy of the capacitor is half that of initial energy
Explanation:
As we know that the energy stored in the capacitor is given as

here we know that capacitance of parallel plate capacitor is given as

V = voltage of battery
so now we have capacitor remains connected to the same battery and the separation between the plates is doubled
so we have

so now the energy stored between the plates is

so new energy of the capacitor is half
An inclined plane makes work easier by breaking an upward or downward movement into smaller increments.
A screw is like an inclined plane wrapped around a cylinder. It turns a small rotational force into a larger forward driving force
