In _______________, brain cells are stimulated using a powerful magnetic field produced by a wire coil placed on a person's head
Masteriza [31]

Answer:Transcranial Magnetic Stimulation (TMS)

Explanation:

Transcranial magnetic stimulation also known as repetitive transcranial magnetic stimulation. TMS is a noninvasive procedure that uses magnetic fields to stimulate nerve cells in the brain to improve symptoms of depression. In TMS, brain cells are stimulated using a powerful magnetic field produced by a wire coil placed on a person's head that temporarily inactivates neural circuits. TMS devices operate completely outside of the body and affect central nervous system activity by applying powerful magnetic fields to specific areas of the brain that we know are involved in depression.

A bus changes its velocity from 5 m/s to 15 m/s in 5 seconds. What is its acceleration?
sladkih [1.3K]

Answer:

\boxed {\boxed {\sf A. \ 2 \ m/s^2}}

Explanation:

Acceleration is the rate of velocity's change with time.

We can calculate it by dividing the change in velocity over time.

a=\frac{v_f-v_i}{t}

Let's define the variables. The final velocity is 15 meters per second. The initial velocity is 5 meters per second. The time is 5 seconds.

v_f= 15 \ m/s \\v_i= 5 \ m/s \\t= 5 \ s

Substitute the values into the formula.

a=\frac{15 \ m/s- 5 \ m/s}{5 \ s }

Solve the numerator first.

  • 15 m/s - 5 m/s= 10 m/s

a=\frac{10 \ m/s}{5 \ s}

Divide.

a= 2 \ m/s/s = 2 \ m/s^2

The acceleration of the bus is <u>2 meters per second squared.</u>
