Answer: The Sun

Explanation:

Water cycle describes the evaporation of water from Earth's surface, formation of clouds and precipitation water back onto the surface of Earth. Seventy percent of the Earth is covered with water in the form of seas and oceans. <u>The heat of the Sun </u>causes the evaporation of water from the surface of the ocean. The water vapors rise and condense to form water droplets. The collection of these water droplets form clouds which rain down again.

The evaporation of the oceans surface water as part of the water cycle is caused by <u>the Sun</u>

If a vehicle accelerating at 2.7 m/s2what is it's velocity at 20 meters 12.63m/s,1.03m/s,10.39m/s,6.39m/s

netineya [11]

Answer:

The final velocity of the vehicle is 10.39 m/s.

Explanation:

Given;

acceleration of the vehicle, a = 2.7 m/s²

distance moved by the vehicle, d = 20 m

The final velocity of the vehicle is calculated using the following kinematic equation;

v² = u² + 2ah

v² = 0 + 2 x 2.7 x 20

v² = 108

v = √108

v = 10.39 m/s

Therefore, the final velocity of the vehicle is 10.39 m/s.

How many neutrons does element x have if it’s atomic number is 40 and it’s mass number is 82?

Black_prince [1.1K]

The atomic number gives you the number of protons element x has. Since the mass of protons and neutrons are almost similar(around 1 amu), the mass number can be thought of as the sum of protons and neutrons. so if element x whose atomic number is 40 has a mass number of 82, then we know that 42 of those must be neutrons.

A light bulb operating at a voltage of 120 v has a resistance of 200 ω. what is the power?

cluponka [151]

The correct is 72 watt

We know that formula of power is $P=\frac{v^{2} }{r}$

so putting the value of Voltage and Resistance in Formula of power so we get

$P=\frac{120^{2} }{200} =72$

What is Power?

Electric power is the rate at which an electric circuit transfers electrical energy per unit time.

Typically, electricity is generated by generators, but it can also be supplied by sources such as electric batteries. The electric power industry typically distributes it via an electric power grid to businesses and homes (as domestic mains electricity).

Transmission lines allow electric power to be delivered over long distances and used for high-efficiency applications such as motion, light, or heat. Electric charges are converted to other forms of energy when they pass through an electric potential difference (voltage).
