Answer:

<u>Option-</u>

In a lunar eclipse, the Moon enters the shadow of Earth from the west side of the orbit.

Explanation:

<u>Lunar Eclipse:</u>

The lunar eclipse occurs when the Earth's position inside the orbital system or pattern of the solar system. As the Moon comes behind the Earth in more simplified words, as the Moon comes from the west side of the orbit. While the shadow of the Earth falls on the Moon's body.

<u>For example:</u>

The lunar eclipse occurs in the US in a very specific manner as we observe the lunar eclipse starts from the west coast of the United states, as it goes all the way towards the east coast of the state or the country.

Answer:

Explained

Explanation:

In lunar eclipse, the Moon enter the shadow of Earth from the west side. This happens because that the direction of moon's orbit around the Earth. Just observe moon at a Night , note its apparent position in the night sky and one the next night note its new position, you find that moon has moved eastward. Therefore in Moon shadow the earth from west to east

the magnitude of the electrical force acting between a +2.4x10-8c charge and 1+1.8x10-6 charge that are separated by 1.008m is

Temka [501]

Answer:

3.83×10¯⁴ N

Explanation:

From the question given above, the following data were obtained:

Charge 1 (q₁) = +2.4x10¯⁸ C

Charge 2 (q₂) = +1.8x10¯⁶ C

Distance apart (r) = 1.008 m

Electrical constant (K) = 9×10⁹ Nm²/C²

Force (F) =?

The magnitude of the electrical force acting between the two charges can be obtained as follow:

F = Kq₁q₂ / r²

F = 9×10⁹ × 2.4x10¯⁸ × 1.8x10¯⁶ / (1.008)²

F = 0.0003888 / 1.016064

F = 3.83×10¯⁴ N

Thus the magnitude of the electrical force acting between the two charges is 3.83×10¯⁴ N

To start a great night of doing physics homework, you sit down to pour yourself a good cup of coffee. Your coffee mug has a mass

astra-53 [7]

Answer:

1) The temperature will be closer to water

2) T = 68.239°C

3) T = 72.142°C

4) T = 69.266 °C

Explanation:

The temperature will be closer to water because the heat capacity of water > heat capacity of coffee.

137(1.089)(T - 23.8) = 137(4.186)(79.8 - T)

⇒(1.089)(T - 23.8) = (4.186)(79.8 - T)

⇒1.089 T - 25.9182 = 334.0428 - 4.186 T

⇒1.089 T + 4.186 T = 334.0428 + 25.9182

⇒5.275 T = 359.961

⇒ T = 68.239°C

137(1.089)(T - 23.8) = 225(4.186)(79.8 - T)

⇒(149.193)(T - 23.8) = (941.85)(79.8 - T)

⇒149.193 T - 3550.7934 = 75159.63 - 941.85 T

⇒149.193 T + 941.85 T = 75159.63 + 3550.7934

⇒1091.043 T = 78710.4234

⇒ T = 72.142°C

137(1.089)(T - 23.8) + 11.7(4.186)(T - 5.2)= 225(4.186)(79.8 - T)

⇒(149.193)(T - 23.8) + 48.9762(T - 5.2) = (941.85)(79.8 - T)

⇒149.193 T - 3550.7934 + 48.9762 T - 254.67624= 75159.63 - 941.85 T

⇒149.193 T + 941.85 T + 48.9762 T = 75159.63 + 3550.7934 + 254.67624

⇒1091.043 T + 48.9762 T = 78710.4234 + 254.67624

⇒1140.0192 T = 78965.09964

⇒ T = 69.266 °C

A car goes around a curve of radius r at a constant speed v. Then it goes around a curve ofradius 2r at speed 2v. What is the ce

Rainbow [258]

The centripetal force on the car as it goes around the second curve is twice that compared to the first.

What is Centripetal force?

It is the force that is necessary to keep an object moving in a curved path and that is directed inward toward the center of rotation.

The formula of Centripetal force is:

F(c) = (m* v^2) / r

Here,

At the first curve,

The curve of radius = r

The constant speed = v

At the second curve,

The car speed (v')= 2 v

The radius of the curve (r')=2 r

According to the formula of centripetal Force:

As the car goes around the second curve,

F'(c) = m*v'^2 / r'

F'(c) = m* (2*v)^2 / 2r

F'(c) = 2* F

Thus,

The centripetal force on the car as it goes around the second curve is twice that compared to the first.

A family has a furnace that uses natural gas to heat their home. They are moving to an area that offers the option of using ener

Murrr4er [49]

The disadvantage will the family most likely face by making this switch is that solar power has a less reliable production of heat.Option A is correct.

<h3>What is a power plant?</h3>

A power plant is an industrial structure that generates electricity. The majority of power plants are linked to the electrical grid.

Nuclear power bare a form of the thermal power plant. You have a reactor where fission takes place and heat is generated, a heat exchanger that transports this heat to where it is needed.

Thermal power plant equipment converts this heat into electric energy, usually via a steam turbine.

The household will most likely experience a disadvantage from this decision in that solar power produces heat less consistently.

Hence option A is correct,
