He waves in terrestrial radiation have a shorter wavelength. Answers: A. The waves in terrestrial radiation have a lower frequency. B. The waves in terrestrial radiation have a shorter wavelength. C. The waves in terrestrial radiation correspond to a higher emission temperature. D. The waves in solar radiation have a longer wavelength.

(C)The waves in terrestrial radiation correspond to a higher emission temperature.

Explanation:

Earth's surface absorbs solar radiation and emits terrestrial radiation. That is  a solar-charged Earth emits long-wave radiation. While water vapor and carbon dioxide molecules merely allow the passage of incoming short waves, they absorb Earth's long waves, heating the atmosphere from the ground up. Terrestrial radiation comes from the earth and solar radiation comes from the sun.

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
