It can be measured in cubic units, kilometers, meters, feet, or centimeters.
Answer:
F = 2 [N], choose option (2)
Explanation:
The principle of impulse is defined by the following expression:
Impulse = Force * Time
Force = force acting [N] or [kg*m/s^s]
Time = time during the impulse [s]
Replacing:
Impulse = 10[kg*m/s^2] * 10 [s]
Impulse = 0,1 [kg*m/s]
Now with this impulse, we can find the force for the new time.
F = Impulse/Time
F = 0.1[kg*m/s] / 0.05[s]
F = 2 [N]
Answer:
higher temperature of copper.
Explanation:
less specific heat capacity.
As the plastic sphere is charged, therefore it experience an electric force when placed in an electric fields and also experiences gravitational force acts downward so the electric force must act upward.
Let is electric force and is gravitational force.
If these forces are balanced, therefore
or
Given, and .
Substituting these values in above equation we get,
Thus, the magnitude of electric field is .
As the charge is negative, the electric field at the location of the plastic sphere must be pointing downward.
Answer:
Explanation:
Given
inclination
coefficient of kinetic friction
As crate is moving Down therefore friction will oppose the motion
using FBD
