Which ball has the greater acceleration at the instant of release?
yuradex [85]

They're equal.

Ignoring air resistance, any object you're not holding onto has the same, constant acceleration ... 9.8 m/s^2 down ... from the moment it leaves your hand until the moment it hits the ground.

It doesn't matter how heavy the object is, and it doesn't matter whether you throw it up, down, or sideways, or just let go and let it drop.

Which colors of light represents the lowest visible frequency?
kodGreya [7K]

Answer:

Red

Explanation:

Red is a colour which has the lowest frequency. Violet has the highest frequency. Frequency has a direct relationship with energy. This means the higher the frequency, the higher the energy. Red has the lowest energy of all the colors too.

The frequency and Energy has an inverse relationship with the wavelength.

However Red has the longest wavelength of about 620 - 780 nanometer.

how does distance change when the amount of effort force is increased while the amount of work dine remains the same
Elodia [21]
Work = Force * Displacement.

If the Work is the same, and the Force is increased, from the formula above it means the displacement would have to be reduced. 

So the displacement (a distance in a specified direction)  would be reduced.

States that Earth processes today are similar to those that took place in the past
Maslowich

Answer;

Uniformitarianism

Explanation;

-Uniformitarianism is the principle suggesting that Earth's geologic processes acted in the same manner and with essentially the same intensity in the past as they do in the present and that such uniformity is sufficient to account for all geologic change.  For example, at an active volcano we can observe lava cooling to form layers of basalt.

James Hutton suggested that deep soil profiles were formed by the weathering of bedrock over thousands of years. He also suggested that supernatural theories were not needed to explain the geologic history of the Earth.
