The equation E = mc² relates energy and mass and the correct option is option D.
The equation was formulated by Albert Einstein as part of his theory of special relativity. In this equation, "E" represents energy, "m" represents mass, and "c" represents the speed of light in a vacuum, which is approximately 3 x 10⁸ meters per second. The equation states that energy is equal to the mass of an object multiplied by the square of the speed of light.
This equation demonstrates the equivalence between mass and energy, suggesting that mass can be converted into energy and vice versa. It is a foundational equation in physics and has significant implications in understanding the relationship between matter and energy.
Thus, the ideal selection is option D.

Answer:
mass
Explanation:
The density of a substance is defined as the ratio of mass of the substance to the volume of the substance.
It is a scalar quantity.
Its SI unit is kg/m^3.
By comparing the densities we get the idea about how dense the substance is.
For example, cotton and iron, the density of cotton is much less than iron so the cotton is less dense than iron.
The relative density is defined as the ratio of density of substance to the density of water at 4 degree C.
The density of water is maximum at 4 degree C.
Final answer:
Density is the mass per unit volume.
Explanation:
Density is a physical property of matter that describes the mass of a substance per unit volume. It is typically expressed in units like grams per cubic centimeter or kilograms per cubic meter. Density helps identify and compare substances, as objects with higher density are heavier for a given volume, while less dense substances are lighter.
Density is the mass per unit volume of a substance or object, defined as p = m/V. The SI unit of density is kg/m³. For many situations, grams per cubic centimeter (g/cm³) are used for the densities of solids and liquids, and grams per liter (g/L) are used for gases.

Final answer:
The force that opposes your push when you attempt to move a box is the frictional force. In a situation where the box doesn't move, it is specifically static friction. If the box was to move, the opposing force would then be kinetic friction.
Explanation:
When you push on a box and find it difficult to move, the force opposing your push is known as frictional force. This is a resistive force that opposes the motion of an object. In a scenario where the box doesn't move at all despite your push, the static friction is equal to the applied force. However, if the box moves, it is the kinetic friction that is work. Frictional force depends on the nature of the contact surfaces and the normal force (force pushing the two surfaces together).

Answer:
18466.68 N
Explanation:
mass of satellite, m = 2210 kg
mass of earth, M = 5.98 x 10^24 kg
distance between surface of earth and the satellite, h = 5.39 x 10^5 m
radius of earth, R = 6.37 x 10^6 m
The force between the earth and the satellite is given by
F = 18466.68 N
Answers
A. 200 m
B. 31.25 m
C. 0.2 m
D. 5 m
Pa = N/m²
m² = N/Pa
12.5 kPa = 12500 Pa
m² = N/Pa
m² = 2500 / 12500
m² = 0.2
C. 0.2 m²
So the correct answer is 0.2m^2
