Answer:

Explanation:Potential Energy is the stored energy of an object given its position relative to a body. Gravitational potential energy is one type of potential energy and is equal to the product of the object's mass (m), the acceleration caused by gravity (g), and the object's height (h) as distance from the surface of the ground (the body).

mass m of 3 kilograms falling at gravity g of 9.81 meter per second squared from a height h of 5 meters. Solve for potential energy Pe with the equation PE equals m times g times h

In this example, a 3 kilogram mass, at a height of 5 meters, while acted on by Earth's gravity would have 147.15 Joules of potential energy, PE = 3kg * 9.81 m/s2 * 5m = 147.15 J.

9.81 meters per second squared (or more accurately 9.80665 m/s2) is widely accepted among scientists as a working average value for Earth's gravitational pull. This figure is based on a measure of gravity at sea level at a latitude of 45°.

At higher altitudes, gravity decreases slightly.

The effect of latitude on gravitational force is relevant as gravity increases with increasing distance from the Equator. At the Equator, the Earth's gravity is 9.780 m/s2 and at the poles it is 9.832 m/s2 (source: CRC Handbook of Chemistry and Physics).

Gravitational acceleration (to three significant figures) for other planets and bodies in the solar system is as follows:

 m/s2 gn*

Sun 274 27.9

Mercury 3.70 0.38

Venus 8.87 0.90

Earth 9.81 1.00

Moon 1.62 0.17

Mars 3.71 0.38

Jupiter 24.9 2.54

Saturn 10.44 1.06

Uranus 8.87 0.90

Neptune 11.15 1.14

Pluto 0.58 0.06

*Standard gravity (gn). 1.00gn is equal to 9.80665 m/s2

Answer:

Volt divided by ampere

Explanation:

V = IR

V/I = R

The unit of resistance from ohms law is volt / ampere. Thus, option A is correct.

Ohm's law states that the applied voltage is directly proportional to the current flow in the conductor. It is written as V ∝ I. It remains constant at room temperature.

V is defined as  potential difference or voltage. The SI unit of voltage is volt(V). I is defined as the current flowing in the circuit. The SI unit of current is ampere (A).

Generally, ohm's law equals to V = IR. R represents resistance of a material which oppose the current flow in the conductor. The unit of resistance is ohm(Ω).

When the potential difference(V) is constant, Resistance is inversely proportional to current. Current increases with decrease of resistance and current decreases with increase of resistance.

To find  equivalent unit of resistance, the ohm's law is :

V = IR

R = V / I

  = volt / ampere.

Hence, the unit of resistance from ohm's law is volt / ampere. The SI unit of resistance is ohm(Ω). Thus, option A is correct.

Answer:

The answer is thus, it is clear that when light passes form air to water, its wavelength decreases to 0.750 times its original value.

Explanation:

hope this helps

It is evident that light's wavelength drops to 0.750 times its original amount when it travels from air to water.

Wavelength is the distance between the equivalent points of two successive waves. When two or particles are referred to be "corresponding points," it means that they are both at the same phase and have completed exactly the same portions of their vibration. Typically, the wavelength of transverse waves—those whose points advance at right angles to one another—is measured from crest to crest or from groove to trough, for longitudinal waves—those whose points advance in the same direction—the wavelength is measured from compaction to compaction or from mass to rarefaction.

A wave train's velocity (v) in a material is equal to its frequency (f), hence the formula for wavelength is v/f. Wavelength is usually represented by the Greek symbol lambda (λ).
