A car interior is heated to 48 C by the sun What type of energy transfer?
Aneli [31]

Answer:

Radiation heat energy transfer

Explanation:

The type of heat transfer from the Sun is radiation heat transfer, which is the transfer of heat through electromagnetic radiation

The distance of the Sun to the Earth is several million kilometers away, with the space between being composes of vacuum and the nuclear reaction in the Sun's core generates vast amount of electromagnetic radiation that is transferred all across the universe and reaches the Earth as visible light and radiant energy at the speed of light

The radiant energy transferred from the Sun heats up the Earth, including the car's interior.

How much current is drawn by a television with a resistance of 30 ω that is connected across a potential difference of 120v?
melomori [17]

By using the Ohms law, we can calculate the current.

Ohms law,

 \frac{V}{I}  = R

Here, V is potential difference, and R is the resistance.

Given,  V=120 V and R = 30 ohm.

Therefore, putting the given values in above relation , we get

\frac{120V}{I} = 30 ohm

or          I=\frac{120}{30} = 4 A

Thus, the current is drawn by a television 4 Ampere

At constant pressure, a sample of a gas occupies 420 ml at 220 K. what volume does the gas occupy at 250 K?
soldier1979 [14.2K]

Answer:

480 mL

Explanation:

Ideal gas law states:

PV = nRT

At constant pressure, nR/P is constant.  Therefore:

V / T = V / T

420 mL / 220 K = V / 250 K

V ≈ 480 mL
