Answer:
Explanation:
The acceleration of an object is given by
where
v is the final velocity
u is the initial velocity
t is the time interval it takes for the velocity to change from u to v
For the car in this problem,
u = 21.0 m/s
v = 46.0 m/s
t = 2.5 s
Substituting, we find the acceleration
Answer:
heat and a little bit of movement
Explanation:
Answer:
charge will be equal to
Explanation:
We have given mass of the particle m = 1.45 gram = 0.00145 kg
Acceleration due to gravity
Electric field E = 700 N/C
Electric force will be equal to , here q is charge and E is electric field
For particle to be stationary this force must be equal to force due to gravity , that is mg force
So qE = mg
So charge will be equal to
