Answer:

C. It is made from three layers of semiconductors.

Explanation:

Bipolar transistors (pnp and npn) are usually made from a sandwich of three semiconductors layers. The main charge carriers are holes and electrons. An npn transistor has two semiconductor junctions that share a thin middle positively enhanced region (the material is enhanced with impurities rich in holes which are the positive charge carriers), and a pnp transistor has two semiconductor junctions that share a thin middle negatively enhanced region (material is enhanced with impurities rich in electrons, the negative charge carriers).

Answer:

P = 5880 J

Explanation:

Given that,

The mass of the block, m = 30 kg

The block is sitting at a height of 20 m.

The block will have gravitational potential energy. The formula for gravitational potential energy is given by :

$P=mgh\\\\=30\times 9.8\times 20\\\\=5880\ J$

So, the required potential energy is equal to 5880 J.

Answer:

$KE2/KE1=0.71$

Explanation:

By conservation of the linear momentum:

m1*V1 = (m1+m2)*V2

Solving for V2:

$V2 = \frac{m1}{m1+m2}*V1$

The kinetic energies are:

$KE1=1/2*m1*V1^2$

$KE2 = 1/2*(m1+m2)*V2^2$

$KE2 = 1/2*(m1+m2)*(\frac{m1}{m1+m2}*V1)^2$

Simplifying:

$KE2 = 1/2*\frac{m1^2}{m1+m2}*V1^2$

The ratio will be:

$KE2/KE1=\frac{1/2*\frac{m1^2}{m1+m2}*V1^2}{1/2*m1*V1^2} =\frac{m1}{m1+m2}$

$KE2/KE1=0.71$

Tommy is awake during a procedure involving his brain his doctor has a test and electrical part of his brain and stimulating it

Amanda [17]

Repetitive Transcranial Magnetic Stimulation (TMS) is the procedure that is being performed on Tommy, while he is awake.

What is Transcranial Magnetic Stimulation?

Transcranial magnetic stimulation (TMS) is a non-invasive method for mood control. It does not require the patient to be sedated and is usually performed on completely conscious patients.

In this procedure, the nerve cells are stimulated by magnetic pulses by placing electromagnetic coils against the scalp of the patient. The patient is then stimulated repetitively which is why it is known as repetitive TMS.

Repetitive TMS can be targeted to specific sites of the brain in contrast to other brain stimulation therapies which are more generalized. Magnetic pulse activates the regions of the brain that show decreased activity during conditions like depression.

Tommy sings during the procedure because the region of the brain responsible for memory and singing is stimulated by this procedure.
