Answer: c) mixture.

Explanation:

An atom is the smallest entity of any substance which consists of subatomic particles called as neutrons, protons and electrons.

An element is a pure substance which is composed of atoms of similar elements. Example: $H_2$

Mixture is formed when atoms of similar or different elements are mixed in no fixed ratio without any chemical combination.

A compound is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass. Example: $H_2O$

Answer:

$T_s = 6.8 degree C$

Explanation:

As per thermal radiation we know that rate is heat radiation is given as

$\frac{dQ}{dt} = \sigma eA (T^4 - T_s^4)$

here we know that

T = 34 degree C = 307 K

$A = 1.38 m^2$

e = 0.557

$\sigma = 5.67 \times 10^{-8} W/m^2K^4$

$\frac{dQ}{dt} = 120 J/s$

now we have

$120 = (5.67 \times 10^{-8})(0.557)(1.38)(307^4 - T_s^4)$

$120 = (4.36 \times 10^{-8})(307^4 - T_s^4)$

$T_s = 279.8 K$

$T_s = 6.8 degree C$

What is the conclusion of coin and feather experiment?

valina [46]

Answer:

So the conclusion is that in presence of air net force acting downward reduces for feather and hence falls slower than coin. But in absence of air resistance, net downward force is just equal to force due to gravity which is same for both coin and feather and hence they fall down at the same rate.

Why is radiation fog more likely near the center of an anticyclone than near the center of a cyclone?

Zigmanuir [339]

Radiation fog is the fog that is formed when the heat absorbed the Earth's surface is released into the atmosphere producing fog. This only occurs when the air is clear and calm. In the center of an anticyclone, the conditions of the air are clear and calm which is favorable for the formation of radiation fog. The center of cyclones, on the other hand, is turbulent and cloudy which prevents the formation of radiation fogs.
