Answer:
Electric field is a function 1/r^2
Explanation:
The displacement of an object is obtained by taking out the area of the rectangle plus the area of the triangle under the line.
<h3>What is acceleration?</h3>
Acceleration is defined as the rate change of velocity with time.
acceleration a = (Δv) / (Δt)
Suppose the initial position of an object is zero, the starting velocity is 3 m/s and the final velocity was 10 m/s. The object moves with constant acceleration.
In velocity time graph, the slope determines the acceleration and the area under the curve gives the value for the displacement.
Thus, the displacement of an object is obtained by taking out the area of the rectangle plus the area of the triangle under the line.

Answer:
A torque of 102.5375 Nm must be exerted by the fireman
Explanation:
Given:
The rate of water flow = 6.31 kg/s
The speed of nozzle = 12.5 m/s
Now, from the Newton's second law we have
The reaction force to water being redirected horizontally (F) = rate of change of water's momentum in the horizontal direction
thus we have,
F = 6.31 kg/s x 12.5m/s
or
F = 78.875 N
Now,
The torque (T) exerted by water force about the fireman's will be
T = (F x d)
or
T = 78.875 N x 1.30 m
T = 102.5375 Nm
hence,
<u>A torque of 102.5375 Nm must be exerted by the fireman</u>

Answer:
The ability to do work is the basic definition of energy. Energy is required to perform any task.
Nuclear fusion reactions happening on sun are the cause of heat, and sun energy.
Proton is the atomic particle with a positive charge just like the electron with the negative charge.
The objects have the kinetic energy during their motion. So the energy of moving object is kinetic energy.
When the objects interact then the friction between their surfaces produces the heat.
The vibration of molecules and the transfer of vibration to the other molecules is because of conduction. Conduction takes place through the vibration of molecules.
Atomic fusion requires extremely high temperatures to occur, that is why it is called thermonuclear.
