Answer:
White
Explanation:
White light is not a color, its'a combination of all colors, the same as black is the absence of all colors. Therefore it cannot be assigned a single wavelength. White light contains all wavelengths from about 390 nm to 700 nm.
Answer:
The angle between the magnetic field and the wire’s velocity is 19.08 degrees.
Explanation:
Given that,
Potential difference, V = 53 mV
Length of the wire, l = 12 cm = 0.12 m
Magnetic field, B = 0.27 T
Speed of the wire, v = 5 m/s
Due to its motion, an emf is induced in the wire. It is given by :
Here,
is the angle between magnetic field and the wire’s velocity
So, the angle between the magnetic field and the wire’s velocity is 19.08 degrees.
Imaging techniques that use wave behaviors are -
- sonography
- X-ray radiography
- CT scan
<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.

Answer:
Metals have more mass per unit of volume than wood.
Explanation:
Density is defined as the amount of matter contained in a unit of volume. A material that is denser than another will therefore have more mass per unit of volume.
The density of a body can affect buoyancy, bodies with low enough densities can float in fluids. For example wood can float in water while metals can't.
