Kinetic energy is the energy of an object due to its motion. An object sitting still isn't moving, therefore it has no kinetic energy. The statement in the question is false.
Answer:
Explanation:
From the question we are told that:
Turns of inner coil
Radius of inner coil
Current of inner coil
Turns of Outer coil
Radius of Outer coil
Generally the equation for Magnetic Field is mathematically given by
Therefore
Condition for the net Magnetic field to be zero
The correct option is C.
From the question given above, it can be seen that the acceleration of the moving object has been reduced from 5 m/s to 3 m/s, this happened because an unbalanced force acted on the object and slowed it down. An unbalanced force is any force that causes a change in motion of a moving object.
Answer:
14500 Pa
Explanation:
Pressure is defined as force acting per unit area and expressed as where F is force and A is area. Given that the force provided is 7250 N and the area is 0.5 square meters, we can substitute them for F and A respectively hence
Since 1 Newton per square meter is equivalent to 1 pascal then 14500 N/m2 is also 14500 Pa
I think the answer is c but I'm not sure
