Beams of X-rays are targeted at a cancerous tumor from outside the body

Explanation:

Mechanical waves helps to treat cancer when beams of x-rays are targeted at a cancerous tumor from outside the body. These beams are energetic and ionizing. This will cause severe destruction of the cancerous cell.

  • In cancer therapy, ionizing radiations are used to destroy cancerous cells in living organisms.
  • Controlled doses of some forms of radiations are particularly known good medical procedures for curing cancer.
  • Other options are not ways in which mechanical waves helps to treat cancer.

A car is traveling at 10 m/s starts to decelerate steadily. It comes to a complete stop in 20 seconds what is it’s acceleration
Ludmilka [50]

Answer:

-0.5 m/s

Explanation:

given:

u (initial velocity) = 10 m/s

v (Final velocity) = 0 m/s (because it is given that it comes to a complete stop)

t (time taken) = 20 s

therefore,

acceleration = v - u / t

a = 0 - 10 / 20  

a = -10 / 20

a =  -1/2

a = -0.5

There is a acceleration of -0.5 m/s

Evidence of wave theory light​
stira [4]

All of these things were seen in formal experiments by the 19th century. But some of them are easy to see in your own home. It's obvious that light can reflect - you just have to look in a mirror. Light bounces off the mirror and goes into your eye so you can see yourself. It's also obvious that light can refract: All you have to do is put a spoon in a large glass of water and watch how the spoon appears to bend.

That happens because the light is bending as it moves between air and water. Both of these things can be seen even more clearly in a laboratory using beams of light or lasers.

A circular saw blade with radius 0.175 m starts from rest and turns in a vertical plane with a constant angular acceleration of
adelina 88 [10]

Answer:

x = 11.23  m

Explanation:

For this interesting exercise, we must use angular kinematics, linear kinematics and the relationship between angular and linear quantities.

Let's reduce to SI system units

    θ = 155 rev (2pi rad / rev) = 310π rad

    α = 2.00rev / s2 (2pi rad / 1 rev) = 4π rad / s²

Let's look for the angular velocity at the time the piece is released, with starting from rest the initial angular velocity is zero (wo = 0)

    w² = w₀² + 2 α θ  

    w =√ 2 α θ

    w = √(2 4pi 310pi)

    w = 156.45  rad / s

The relationship between angular and linear velocity

    v = w r

    v = 156.45  0.175

    v = 27.38 m / s

In this part we have the linear speed and the height that it travels to reach the floor, so with the projectile launch equations we can find the time it takes to arrive

    y = v_{oy} t - ½ g t²

As it leaves the highest point its speed is horizontal

   y = 0 - ½ g t²

   t = √ (-2y / g)

   t = √ (-2 (-0.820) /9.8)

   t = 0.41 s

With this time we calculate the horizontal distance, because the constant horizontal speed

   x = vox t

   x = 27.38 0.41

   x = 11.23  m
