<h3>How can mechanical waves help in the treatment of cancer?</h3>


Ultrasound is used to improve absorption of a radioactive pellet by a tumor. The radioisotope in a radiopharmaceutical releases sound waves into surrounding cells. Beams of X-rays are targeted at a cancerous tumor from outside the body.

<h3>How can mechanical waves help the treatment of cancer?</h3>

HIFU is a cancer treatment that uses high-frequency sound waves. You have HIFU from a machine. The machine gives off the sound waves which deliver a strong beam to a specific part of a cancer. This heats and destroys the cancer cells.

HIFU can treat a single tumour or part of a large tumour. But it is not suitable for people with cancer that has spread to more than one place in their body.

A 60-W light bulb runs on 120 V and draws 0.50 A of current when running
Pavlova-9 [17]

Answer:

3600 J

Explanation:

According to given question

P(rated)=60w

V= 120

I =0.50 A

t=600 second

Now,

Energy can be calculated as :

E= VI*t

Where,

V is voltage

I is current

t is time in second

Now,

Putting the all value in above equation E

So,

E=120*0.5*600\\E=36000 J

Therefore, 36000 J energy use up by light bulb

A 3 kg bowling ball is thrown onto a mattress. If it takes 0.3 seconds to stop the ball using a force of 24 N, what was the init
enyata [817]

Answer:

-24 m/s

Explanation:

mass of the bowling ball =  3 kg

time (t) = 0.3 seconds

Force = 24 N

initial velocity u = ???

We know that;

Force = mass × acceleration (a)

So;

24 = 3 × a

a = 24/3

a = 8 m/s²

Also;

From equation of motion; acceleration is given by the relation;

a =\frac{v-u}{t}

if v = 0

then ;

8 = \frac{0-u}{0.3}

24 = 0- u

u = -24 m/s

Thus; the  initial velocity of the bowling ball when it first touched the mattress =  -24 m/s
