Use the equation
plug in the variables for the equation. Use 0 for Vf because at the highest point the velocity would be zero. Use -9.8 for acceleration because that is the speed at which gravity pulls down.
your answer would be 2.06122 seconds.
50% Because there are two sides of the penny so the chances will always be 50/50
Answer:
The gravitational force between the sun and the earth drops to (1/16) of its original value.
Explanation:
According to the gravitational law, gravitational force between two bodies is directly proportional the product of the masses of the two bodies and inversely proportional to the square of their distances apart.
If the two masses and the other constants of proportionality are held constant, the gravitational force between two bodies is inversely proportional to the square of their distances apart.
F ∝(1/R²)
If the initial gravitational force between the sun and the earth is given by F₀ and the distance between the sun and the earth is R₀.
F₀ = (k/R₀²)
where k is constant regardless of the values of corresponding gravitational forces and distances apart.
Then, let the new distance apart be R₁,
R₁ = 4 R₀
The new gravitational force between the sun and the earth, F₁ will be given by
F₁ = k/(R₁²)
Recall, R₁ = 4 R₀
F₁ = k/(4R₀)² = k/16(R₀²) = F₀/16
Hence, the gravitational force between the sun and the earth drops to (1/16) of its original value.
I'm assuming you want the first law of thermodynamics.
The First Law of Thermodynamics states that heat is a form of energy and cannot be created or destroyed. It can, however, be transferred from one location to another and can be converted into other forms of energy.
