Answer
Voltage is how fast the electrons flow. Power is a use of voltage times the volumes of electrons. The higher the voltage the more power you have with the same current.
Answer:
It's actually
F=ma
Force=Mass x Acceleration
So...when we inverse it..
It becomes:
B. a= F/m
She misses. She should have accelerated faster in order to get to her target.
Answer: A
Explanation:
Molecules speed up as heat is added
For example when water is heated as the water gets hotter the molecules speed up causing the water to boil and change phases into a gas (this is called evaporation)
In an ice cube the water molecules are frozen (barely moving compressed tight together) as the ice cube heats up the molecules start speeding up and moving further apart as the ice cube turns into liquid form. So as heat is added molecules speed up, move faster and spread further apart
Answer:
6 N
Explanation:
= Mass flow rate = 1 kg/s
v = Final velocity = 6 m/s
u = Initial velocity = 0 m/s
Force is obtained when we divide change in momentum by time
The force the person exert on the extinguisher in order to prevent it from accelerating is 6 N
