Which statements describe solstices? Select 3 correct choices. They occur when the Sun reaches its highest or lowest point in th

e sky. They affect the amount of sunlight in the Northern Hemisphere in June. They contribute to the cycling of winters all year long in the Northern Hemisphere. They influence the cycling of different seasons based on the Sun’s height in the sky. They increase the amount of rays from the Sun directly received in the Southern Hemisphere.

The statements that best describe solstices include:

A. They occur when the Sun reaches its highest or lowest point in the sky.

B. They affect the amount of sunlight in the Northern Hemisphere in June.

D. They influence the cycling of different seasons based on the Sun's height in the sky.

A solstice can be defined as a phenomenon in which the Sun reaches its maximum or minimum declination relative to the celestial equator on the celestial sphere, thereby, producing either the least amount of daylight time within a day or the most amount of daylight time. Also, it occurs twice in a year between June 20-22 and December 21-23.

Traditionally, solstice marks the beginning (start) of seasons such as summer and winter depending on the hemisphere.

Hence, the statements that best describe solstices include:

  • Solstices occur when the Sun reaches its highest (maximum) or lowest (minimum) point in the sky.
  • Solstices affect the amount of daylight time (sunlight) in the Northern Hemisphere in June.
  • Solstices influence the cycling of different seasons depending on the Sun's height in the sky.

soldi70 [24.7K]
Solubility indicates the maximum amount of a substance that can be dissolved in a solvent at a given temperature. Such a solution is called saturated. Divide the mass of the compound by the mass of the solvent and then multiply by 100 g to calculate the solubility in g/100g .

You push very hard on a heavy desk, trying to move it. You do work on the desk:
frozen [14]

Answer:

(C) Only if it starts moving

Explanation:

We know that work done is given by

W=F.d=Fdcos\Theta

So there are two case in which work done is zero

First case is that when force and displacement are perpendicular to each other

And other case is that when there is no displacement

So for work to be done there must have displacement, if there is no displacement then there is no work done

So option (c) will be the correct option

a ball of mass 16 kg on the end of a string is spun at a constant speed of 2 m/s in a horizontal circle with a radius of 1m. Wha
miss Akunina [59]

The work done by the centripetal force during om complete revolution is 401.92 J.

<h3>What is centripetal force?</h3>

Centripetal force is a force that acts on a body undergoing a circular motion and is directed towards the center of the circle in which the body is moving.

To Calculate the work done by the centripetal force during one complete revolution, we use the formula below.

Formula:

  • W = (mv²/r)2πr
  • W = 2πmv²................... Equation 1

Where:

  • W = Work done by the centripetal force
  • m = mass of the ball
  • v = velocity of the ball
  • π = pie

From the question,

Given:

  • m = 16 kg
  • v = 2 m/s
  • π = 3.14

Substitute these values into equation 1

  • W = 2×3.14×16×2²
  • W = 401.92 J

Hence, The work done by the centripetal force during om complete revolution is 401.92 J.
