Answer:
Movement of Galaxies away from us.
Explanation:
Big Bang theory is the most widely accepted theory which says that the universe started with a huge expansion, it was not an explosion. By that logic everything must be moving from each other even today. This was proved by observing the Redshift in the spectrum of the galaxies which means that they are moving away from us.
The Objects separated by gravitational force of 360 N, masses 6.25 × 10¹⁴ kg and 7.20 × 10⁵ kg. Applying Newton's law with G = 6.67430 × 10⁻¹¹ m³ kg⁻¹ s⁻² yields distance is 2.79139 km.
We can apply Newton's law of universal gravitation to calculate the distance between the two objects. The formula takes the form:
F = (G ⋅ m₁ ⋅ m₂) / r²
Where:
F represents the force between the two objects
G stands for the gravitational constant (6.67430 × 10⁻¹¹ m³ kg⁻¹ s⁻²)
m₁ and m₂ denote the masses of the two objects
r indicates the distance between the centers of the two objects
Given that the force F = 360 N, m₁ = 6.25 × 10¹⁴ kg, and m₂ = 7.20 × 10⁵ kg, we can solve for r:
r² = (G ⋅ m₁ ⋅ m₂) / F
r = √((G ⋅ m₁ ⋅ m₂) / F)
Now, substituting the values and solving for r:
r = √(((6.67430 × 10⁻¹¹ m³ kg⁻¹ s⁻²) ⋅ (6.25 × 10¹⁴ kg) ⋅ (7.20 × 10⁵ kg)) / 360 N)
r ≈ 2791.39 m
Finally, converting the distance from meters to kilometers:
r ≈ 2.79139 km
Consequently, the two objects are approximately 2.79139 kilometers apart.

The correct answer to the question is : B) The weight of the water, and C) The height of the water.
EXPLANATION :
Before coming into any conclusion, first we have to understand potential energy of a body.
The potential energy of a body due to its position from ground is known as gravitational potential energy.
The gravitational potential energy is calculated as -
Potential energy P.E = mgh
Here, m is the mass of the body, and g is the acceleration due to gravity.
h stands for the height of the body from the ground.
We know that weight of a body is equal to the product of mass with acceleration due to gravity.
Hence, weight W = mg
Hence, potential energy is written as P.E = weight × height.
Hence, potential energy depends on the weight and height of the water.
Answer:
fixed distances from the nucleus of an atom where electrons may be found
Explanation:
A. 200 J
B. 330 J
C. 352 J
D. 220 J
Answer: Option (C) is the correct answer.
Explanation:
Work is defined as the energy required when force is applied in a certain direction.
The expression for work, force and distance is as follows.
W = F × d
where, W = work
F = force
d = distance
It is given that force applied to drag the box is 22 N and distance is 16 meters. Therefore, calculate work done as follows.
W = F × d
= 22 N × 16 meters
= 352 Nm (1 Newton meter = 1 joule)
or, W = 352 J
Thus, we can conclude that amount of work done is 352 J.
A mass is stretched 4 centimeters from the equilibrium position of a spring. The restoring force will also double if the displacement doubles.
The restorative force is a force that acts to return a body to its equilibrium position. The restoring force is always directed back toward the system's equilibrium position and is solely determined by the position of the mass or particle. The restoring force is frequently mentioned in basic harmonic motion.
F = k Hooke's law force or spring force are other names for x. In this equation, x represents the displacement from equilibrium or deformation, F represents the restoring force, and k represents a constant relating to how difficult it is to deform the system. The minus sign represents a restoring force acting in the opposite direction of the displacement.
Thus, The restoring force will also double if the displacement doubles.
