How do we get heat on Earth? Does thermal energy travel directly from the sun?

1 answer:

7 0

We get heat on earth from the sun. Energy from the sun is transferred through space and through earths atmosphere to the earths surface. And since this warms the earth surface it creates heat.

A spinning turbine at an electrical plant produces energy that flows through wires to your house. The energy in the wires can be

Anna007 [38]

The spinning turbine converts mechanical energy into electrical energy that is converted into light energy used to light up the house.

<h3>What is law conservation of energy?</h3>

The law of conservation of energy states that energy can neither be created nor destroyed but can be transformed from one form to another.

The spinning turbine works on the principle of mechanical energy.

Thus, the spinning turbine converts mechanical energy into electrical energy that is converted into light energy used to light up the house.

a DJ uses a 110-volt outlet to plug in a strobe light. if the current flowing through the light is 0.050 amps, how much resistan

tigry1 [53]

Ohms Law: V = IR

V is the voltage in volts

I is the current in amps

R is the resistance in Ohms

Rearrange: R = V/I

R = (110)/(0.050)

R = 2200

There are 2200 Ohms of resistance in the circuit.

Kyle has the mass of 54 kg and is jogging at a velocity of m/s. What is Kyle’s kinetic energy

inysia [295]

m = mass = 54 kg

v = velocity = 3 m/s

KE = (1/2)*m*v^2

KE = (1/2) * 54 * (3)^2

KE = 243 J

Hope this helps!

A spacecraft in the shape of a long cylinder has a length of 100 m, and its mass with occupants is 1 480 kg. It has strayed too

maks197457 [2]

Answer:

2352645198509.9604 m/s²

Explanation:

G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²

M = Mass of black hole = $90\times 1.989\times 10^{30}\ kg$

$R_{f}$ = 10000+100 m

$R_{sb}$ = Distance between the nose and the center of the black hole = 10000 m

The difference in the gravitational field in this system is given by

$\Delta F=\dfrac{GMm}{R_{f}^2}-\dfrac{GMm}{R_{sb}^2}\\\Rightarrow \Delta g=GM\left(\frac{1}{R_f^2}-\frac{1}{R_{sb}^2}\right)\\\Rightarrow g=6.67\times 10^{-11}\times 90\times 1.989\times 10^{30}\left(\frac{1}{(10000+100)^2}-\frac{1}{10000^2}\right)\\\Rightarrow \Delta g=-2352645198509.9604\ m/s^2$

The acceleration is 2352645198509.9604 m/s²
