Question no-2 (10 mark)
find the anguler momentum of a body if K.E = 4 jule and M.I = 2kg m2.

Answers

Answer 1
Answer:

Answer:

KE = 1/2 I ω^2

Given I = 2 kg m^2 and KE = 4 J

ω = (2 KE / I)^1/2 = (2 * 4 / 2)^1/2 = 2^1/2 sec

P = I ω        definition of angular momentum

P = 2 kg m^2 * (2 KE / I)^1/2 / sec = 2 * 2^1/2 kg m^2 / sec

Nuclear energy use can negatively impact water quality. Please select the best answer from the choices provideda. True
b. False

Answers

The correct answer is B. Nuclear energy use do not have a negative impact on water quality. Although, it might have an effect on life in water bodies. Nuclear power generation requires a lot of water for cooling and heating. Many power plants are situated near bodies of water because this is where they get their water for processing. They use screens in order to minimize entry of foreign materials and in these screens aquatic organisms might be trapped and killed.

the correct answer is true.

Jose has a solid green ball. Which color(s) of light does this ball reflect? A.
blue and yellow

B.
green

C.
all colors except green

D.
white

Answers

If the ball is green, then it is absorbing all the colors of light except green. This means that it is reflecting or denying the absorption of green light, that is why the ball is green. Therefore, your answer would be B.

Hope I helped :)

About 85% sure on this one. 
The ball reflects the green because the ball absorbs all the other colors except green so that's why its the green light is covering it and its absorbing everything else

The term pressure most nearly refers to which of the following?A. another term for density
B. a property of water near the ocean bottom
C. force per area created by the weight of water
D. the pushing of ocean currents on objects in the ocean

Answers


The correct answer would be C. force per area created by water.
pressure is force per unit area or p=f/a. The pressure at the bottom of the ocean =weight of overlying water /1m^2. Think of it as the weight of a column of water 1 meter square sitting on the ocean floor. so the correct answer is "C".
