Answer 2

the speed of a wave with a wavelength of 0.5 m and a frequency of 20 Hz is 10

what is speed ?

Speed can be referred as the ratio of distance to the time in which the distance was covered which is a scalar quantity as it has only direction and no magnitude.

The speed is represented as s=d/t, Where, s is the speed in m.s-1, d is the distance traveled in m, t is the time taken in s

There are four types of speed like Uniform speed, Variable speed, Average speed, Instantaneous speed

Uniform speed is where the object covers equal distance at equal interval of time, variable speed is defined as when the object covers a different distance at equal intervals of times.

Instantaneous speed is defined as an object is moving with variable speed, then the speed at any instant of time is known as instantaneous speed.

Why might a person who has skin cancer later
develop a tumour on her lungs?

Answers

Answer: The cancer of the skin metastasizes into the lymph joints (spreads), and they run everywhere in the body, dropping bad cells when they go. the lungs are super vascular (carry a lot of blood flow), and so is the organ. Therefore, they are favorite places for the cancer cells to end up and grow.

Explanation: hoped this helped:)) you can just search it up

Results showed that people with nonmelanoma skin cancer were at an increased risk of developing the deadly skin cancer melanoma, and that women with nonmelanoma skin cancer were at increased risk of lung cancer and breast cancer, according to the study. Common sites for metastases include the lymph nodes, lungs, liver, bones and brain. Melanoma tumors that have metastasized to other parts of the body are still considered melanoma. For example, melanoma found in the lungs is called metastatic melanoma of the lung or melanoma with lung metastases. Skin cancer is the out-of-control growth of abnormal cells in the epidermis, the outermost skin layer, caused by unrepaired DNA damage that triggers mutations. These mutations lead the skin cells to multiply rapidly and form malignant tumors. Hope this helps!
