Answer:

39,000 Joules of Work

Explanation:

Work can be found out through the change in Kinetic Energy.

W = ΔKE

Change in KE is:

W = KE_{Final}  - KE_{Initial}

Expand the equation you get:

W=\frac{1}{2} mv^{2}_{f}  -\frac{1}{2} mv^{2}_{i}

Plugin the known values and solve:

W=\frac{1}{2} (500)(16)^{2}  -\frac{1}{2} (500)(10)^{2}

W=(250)(256)  -(250)(100)

W=64000-25000

W=39000 J

If a transformer has 50 turns in the primary winding and 10 turns on the secondary winding, what is the reflected resistance in
Elza [17]

Answer:

The reflected resistance in the primary winding is 6250 Ω

Explanation:

Given;

number of turns in the primary winding, N_P = 50 turns

number of turns in the secondary winding, N_S = 10 turns

the secondary load resistance, R_S = 250 Ω

Determine the turns ratio;

K = \frac{N_P}{N_S} \\\\K = \frac{50}{10} \\\\K = 5

Now, determine the reflected resistance in the primary winding;

\frac{R_P}{R_S} = K^2\\\\R_P = R_SK^2\\\\R_P = 250(5)^2\\\\R_P = 6250 \ Ohms

Therefore, the reflected resistance in the primary winding is 6250 Ω

If an object is accelerating to the right , then net force on the object must be directed towards the right ! True Or False ?
vichka [17]
Not so fast.

I think you're using 'accelerating' to mean 'speeding up', but you really need
to be more careful with it. "Acceleration" means ANY change in speed OR
direction.

If an object's speed to the left is decreasing, or its speed to the right is
increasing, then the net force on the object must be directed towards
the right.

If an object is moving with constant speed in a circular path, then it's
constantly accelerating, because its direction is constantly changing.
The force on it is always directed towards the center of the circle, so
there's one point on the path where the force is directed straight to the right.
