Spring Tides are formed by the constructive interference of bulges created by the moon and sun. Spring Tides occur when the Sun, Moon and the Earth are aligned. Neap Tides are formed by the destructive interference created by the moon and sun. Neap tides occur when the Sun, Moon, and Earth align to make a right angle.
The range of force exerted at the end of the rope is 285.7 N to 1,000 N.
<h3>Net horizontal force of the cylinder</h3>
The net horizontal force of the cylinder when it is at equilibrium position is determined by applying Newton's second law of motion.
∑F = 0
F - μFn = 0
F - 0.2(5,000) = 0
F - 1,000 = 0
F = 1,000 N
The strength of the applied force increases as the number of turns of the rope increases.
minimum force = total force/number of turns of rope
minimum force = 1,000/3.5
minimum force = 285.7 N
Thus, the range of force exerted at the end of the rope is 285.7 N to 1,000 N.

Answer:
Mass of the steel cube = 7800 kg
Volume of the steel = 1.025 cubic centimetre
Explanation:
Given:
The density of the steel = 7.8
Side of the cube = 12 cm
<u>(1)The mass of steel cube :</u>
We know that,
![Density = \frac{Mass}{Volume}](https://tex.z-dn.net/?f=Density%20%20%3D%20%5Cfrac%7BMass%7D%7BVolume%7D)
We are given with density and sides of the cube
then volume of the cube
=
= ![10^3](https://tex.z-dn.net/?f=10%5E3)
= 1000 cubic centimetre
Now
![7.8 = \frac{mass}{1000}](https://tex.z-dn.net/?f=7.8%20%3D%20%5Cfrac%7Bmass%7D%7B1000%7D)
![mass = 7.8 \times 1000](https://tex.z-dn.net/?f=mass%20%3D%207.8%20%5Ctimes%201000)
mass = 7800 kg
<u>(2)volume of steel:</u>
Given the mass = 8 kg
![Density = \frac{Mass}{Volume}](https://tex.z-dn.net/?f=Density%20%20%3D%20%5Cfrac%7BMass%7D%7BVolume%7D)
Substituting the values
![7.8 = \frac{8}{volume}](https://tex.z-dn.net/?f=7.8%20%3D%20%5Cfrac%7B8%7D%7Bvolume%7D)
![volume = \frac{8}{7.8}](https://tex.z-dn.net/?f=volume%20%3D%20%5Cfrac%7B8%7D%7B7.8%7D)
volume = 1.025 cubic centimetre
Before a star is born, the matter that will become the star exists as a interstelar gas and dust. The stars are formed as a result of the forces:the force of gravity compresses atoms in the interstellar gas. Then the fusion reaction begins. During this fusion reaction the temperature gets extremely high and all the material evolves into a hot bright star.
Answer:
-2.33 m/s²
Explanation:
The computation of the skateboarder’s acceleration is shown below;
Acceleration means the change in velocity per unit with respect to time.
In the given case, the initial velocity is 7 m/s.
As in the question it is mentioned that it comes to a stop, so the final velocity would be zero.
And, The time elapsed is 3 seconds.
Now the following equation should be used
a = (v,final - v,initial) ÷ t
= (0 - 7)/3
= -2.33 m/s²
