A 100 N force causes an object to accelerate at 2 m/s2. What is the mass of the<br> object?
satela [25.4K]

Answer:

50 kg

Explanation:

Given,

Force ( F ) = 100 N

Acceleration ( a ) = 2 m/s^2

To find : Mass ( m ) = ?

Formula : -

F = ma

m = F / a

= 100 / 2

m = 50 kg

Therefore, the mass of the object is 50 kg.

if a diffraction grating produces a third-order bright spot for red light (of wavelength 650 nm ) at 68.0 ∘ from the central max
Mashutka [201]

Answer:

The angle is 25.34°.

Explanation:

Given that,

Wave length = 650 nm

Angle = 68.0°

We need to calculate the distance

For a diffraction grating

d\sin\theta=m\lambda

d=\dfrac{2\times650\times10^{-9}}{\sin68.0}

d=2.10\times10^{-6}\ m

We need to calculate the angle

Using formula for angle

d\sin\theta=m\lambda

\sin\theta=\dfrac{m\times\lambda}{d}

\sin\theta=\dfrac{2\times450\times10^{-9}}{2.10\times10^{-6}}

\sin\theta=25.34^{\circ}

Hence, The angle is 25.34°.

<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.
