Answer:

The moon is actually quite dim.

Explanation:

compared to other astronomical bodies. The moon only seems bright in the night sky because it is so close to the earth and because the trees, houses, and fields around you are so dark at night. In fact, the moon is one of the least reflective objects in the solar system.

Two charged plates separated by 15 cm create a uniform electric field of 360 n/c. what is the potential difference between the p
nikitadnepr [17]

When two charged plates are separated by a distance, the potential difference between the plates is 54 Volts.

<h3>What is uniform electric field?</h3>

The electric field intensity which does not increase or decrease with time or remain constant is called the uniform electric field.

Given is the plates separated by distance d = 15 cm =0.15 m, electric field E= 360 N/C.

The relation between the electric field and voltage is

E=V/d

Substitute the values into the expression to get the potential difference V,

V = 360 x 0.15

V = 54 Volts

Thus, the potential difference between the plates is 54 Volts.

If our planet was without its ocean but otherwise the same as it is today, would surface temperatures be more extreme than they
Doss [256]
They would actually be so extremely hot that the whole earth would become a desert without any real seasons. The lack of water would also make it unable to sustain human life. Then slowly the planet would most likely have it's atmosphere in short exclamation, "It would go away." And then our planet would probably end up looking very similar to the red planet -- Mars.

What quantity of heat is required to change 20g of ice at -25°c to steam at 120°c
Oksana_A [137]

Answer: 5289 joules

Explanation:

The quantity of Heat Energy (Q) required to heat a substance depends on its Mass (M), specific heat capacity (C) and change in temperature (Φ)

Thus, Q = MCΦ

Since, Mass of ice = 20 g

C is not provided (Recall that the specific heat capacity of ice is 2.010J/g°C)

Φ = (Final temperature - Initial temperature)

(120°C - (-25°C) =

120°C + 25°C = 145°C

Thus, Q = 20g x 2.010J/g°C x 145°C

Q= 5829J

Thus, 5829Joules of heat energy is required to heat ice
