Explanation / Answer
Ans 10- c) pushing the rock over a cliff. Because in physics for work to be done there needs to be displacement of the body.
Ans 11- d) when it strikes matter. Because radiant energy can travel through space without heating it and ho heat is produced when it is reflected
Ans 12- d) all of these. Because plants need radiant energy to grow which ultimately turns into oil, and wind and water movements are based on the temperature gradient.
Ans 13- c) mass. Because volume would be different and density is a function of volume.
Ans 14- b) quantitative data involving measurement. Because density is a physical quantity.
Ans 15- a) floats on top of the water because it is less dense than water.
Ans 16- c) can severely affect the waterfowl and other organisms living on the surface of the water. Because oil floats on the surface of the water.
Ans 17- d)all of these
Ans 18- b) greater than the surface area of the light shown directly downward. Because when the light is shown directly down the angle is near 90° and the light is the least spread out.
Ans 19- a) at a more slant than during summer. Because during winter the distance between the place and the sun is more than in summer.
Ans 20- a) the beginning of summer. Since Australia is in the southern hemisphere their seasons are opposite of that we experience in the northern hemisphere June 21 is their summer solstice.
Ans 21- c) the beginning of summer. Because June 21 is the summer solstice in the northern hemisphere.
