Questions and Answers

1.

Write the formula with:average-speed distance time

Explanation
The formula for average speed is calculated by dividing the distance traveled by the time taken. This formula allows us to determine the average rate at which an object is moving over a given distance and time period. By dividing the distance by the time, we can find the average speed of an object.

The formula for calculating the energy of a photon is: E = ______ * f

Explanation
This formula, proposed by Max Planck, is a fundamental equation in quantum mechanics. It describes the relationship between the energy of a photon and its frequency.
E represents the energy of the photon.
h is Planck's constant, a fundamental physical constant that relates a photon's energy to its frequency.
f is the frequency of the photon.
The energy of a photon is directly proportional to its frequency. This means that photons with higher frequencies, such as gamma rays, have 1 higher energies than photons with lower frequencies, such as radio waves.

In the context of simple harmonic motion, the period of oscillation is represented by the formula T = 2π√( ______ / g)

Explanation
This formula calculates the period of a simple pendulum, which is the time it takes for one complete swing back and forth.
T represents the period of oscillation.
π is a mathematical constant (approximately 3.14159).
L is the length of the pendulum.
g is the acceleration due to gravity.
The period of a simple pendulum is directly proportional to the square root of its length and inversely proportional to the square root of the acceleration 1 due to gravity. This means that a longer pendulum will have a longer period, while a stronger gravitational field 2 will result in a shorter period.

Write the formula with:weight mass gravitational-field-strength

Explanation
The formula provided states that weight is equal to the product of mass and gravitational field strength. This formula is derived from the relationship between an object's mass and the force of gravity acting on it. The weight of an object is directly proportional to its mass and the strength of the gravitational field it is in. Therefore, multiplying the mass of an object by the gravitational field strength gives us its weight.

Write the formula with:pressure force area

Explanation
The formula for pressure is given by dividing the force applied on an object by the area over which the force is distributed. This relationship shows that pressure is directly proportional to force and inversely proportional to the area. Therefore, as the force increases, the pressure also increases, while increasing the area over which the force is spread decreases the pressure.

The formula for calculating the gravitational force between two objects is: F = G * (m1 * m2) / ______

Explanation
This formula, known as Newton's Law of Universal Gravitation, calculates the force of attraction between any two objects with mass.
F represents the force of gravity.
G is the gravitational constant.
m1 and m2 are the masses of the two objects.
r is the distance between the centers of the two objects.
The force of gravity is directly proportional to the product of the masses and inversely proportional to the square of the distance between them. This means that more massive objects exert a stronger gravitational pull, but the force weakens rapidly as the distance between the objects increases.
