Earth's greenhouse gases trap heat in the atmosphere and warm the planet.

Sergeeva-Olga [200]3 years ago
4 0

Answer:

The answer to this problem is D.

Explanation:

Firstly, light from the sun passes through Earth's atmosphere to reach Earth's surface and heat the planet. However, some of this light is radiated back into space in the form of infrared radiation. This radiation is trapped by Earth's greenhouse gases in the atmosphere, causing Earth's surface to heat up. For this reason, choice D makes the most sense.

A student has four resistors. Each resistor has a resistance of 100 ohms.
ValentinkaMS [17]

Answer:

The minimum resistance is 25 ohms.

Explanation:

Resistance of each resistor is 100 ohms. When resistors are connected in parallel, the equivalent resistance is lowest. For parallel combination, the equivalent resistance is given by :

\dfrac{1}{R}=\dfrac{1}{R_1}+\dfrac{1}{R_2}+....

Here, all resistors are 100 ohms. So,

\dfrac{1}{R}=\dfrac{1}{100}+\dfrac{1}{100}+\dfrac{1}{100}+\dfrac{1}{100}\\\\R=25\ \Omega

So, the minimum resistance is 25 ohms.
