Answer:
Load
Explanation:
A normal power supply can deliver up to certain amount of power to a load. The output power can be calculated multiplying Voltage (V) x Current (A). It happens that after a certain period of time, the power source's main components begin to wear, thus losing its ability to deliver its nominal power. Normally, when no load its connected to the source, you will get the operating Voltage, but when the load demands power, the ability to deliver power to it may fail to reach nominal levels. When connected, there may be voltage drops (thus, less power output) causing malfunctions turning it into a non-operative power supply.

Answer:
<em>The water hits the wall at a height of 5.38 m</em>
Explanation:
<u>Projectile Motion
</u>
It's the type of motion that experiences an object projected near the Earth's surface and moves along a curved path exclusively under the action of gravity.
The object describes a parabolic path given by the equation:
Where:
y = vertical displacement
x = horizontal displacement
θ = Elevation angle
vo = Initial speed
The hose projects a water current upwards at an angle of θ=40° at a speed vo=20 m/s.
The height at which the water hits a wall located at x=8 m from the hose is:
Calculating:
y = 5.38 m
The water hits the wall at a height of 5.38 m

J
Explanation:
The total mechanical energy of an object or system is given by:
E
m

c
h
=
K
+
U
Where
K
is the kinetic energy of the object and
U
is the potential energy of the object. The carriage, sitting motionless at the top of the hill, has only potential energy in the form of gravitational potential energy.
Gravitational potential energy is given by:
U
g
=
m

h
Where
m
is the mass of the object,
g
is the gravitational acceleration constant, and
h
is the height of the object above some specific reference point, in this case the ground

below.
The weight of a stationary object at the surface of the earth is equal to the force of gravity acting on the object.
