According to universal gravitation, both mass and air resistance affect the gravitational attraction between objects

Answers

Air resistance doesn't appear in the formula for gravitational force, because it doesn't affect it. Mass does because it does.

False, it would be only mass who does it.

Which describes the eye of a hurricane?a. brings winds of up to 300 km/h
c. has strong, spinning winds
b. has warm, calm air and light winds

Answer:

b. has warm, calm air and light winds

Explanation:

The eye of a hurricane is calm and "peaceful", it's the region with calm weather. But the eyewall is really dangerous, due to its pressure and speed difference. Actually, the eyewall has the most severe winds and weather. Another important characteristic is that the eye has the lower pressure.

So, among the options, b. is the right answer.

b. has warm, calm air and light winds

What is Wave ?

Wave is is a disturbance in a medium that carries energy as well as momentum . wave is characterized by amplitude, wavelength and phase. Amplitude is the greatest distance that the particles are vibrating. especially a sound or radio wave, moves up and down. Amplitude is a measure of loudness of a sound wave. More amplitude means more loud is the sound wave.

Wavelength is the distance between two points on the wave which are in same phase. Phase is the position of a wave at a point at time t on a waveform. There are two types of the wave longitudinal wave and transverse wave.

Hence option D is correct.
