Answer:
90m/s
Explanation:
acceleration depicts the rate of change in velocity per time, therefore an acceleration of 3m/s² means the object increases its velocity 3m/s every second therefore the second squared in the denominator
acceleration = (3m/s)/1s =3m/s²
Therefore, if the plane starts from rest (initial speed = 0m/s) and it increases 3m/s every second for 30 seconds you would have:
final_speed = initial_speed + 3m/s²*30s =0+3*30 m*s/s² = 90 m/s
Answer:
The magnitude of the electric field is
Explanation:
Given:
Charge of electron C
Separation between two charges m
For finding the magnitude of the electric field,
Where
Therefore, the magnitude of the electric field is
Answer:
A strong nuclear force pulls together protons and neutrons in the nucleus
Explanation:
Answer:
North of East
Explanation:
two forces on the hockey puck is given as
at 15 degree North of East
similarly other force is
at 55 degree North of East
Now net force on the puck is given as
magnitude of force is given as
magnitude of acceleration
direction of acceleration is given as
North of East
