Answer: 2*10^-3 nC
Explanation: The capacitor of two plates is given by C= εoA/d where A and d , are the area and the separation of the plates, respectively.
We also know that C=Q/V and V=E*d ( E=electric field between the plates)
From the above expression we have:
Q= εo*A*E= 8.85 ^10-12*7.54 * 10^-4*300= 2*10^-3 nC
The factor that can have a significant influence on a planet’s surface temperature is its atmosphere.
<h3>What is the role of the atmosphere in the planet's temperature?</h3>
The atmosphere plays a fundamental role in the Earth planet's temperature because it allows the entry and out of certain types of radiation that may increase the temperature.
The role of the atmosphere in the Earth's temperature is well documented because our temperature is thick and it increases its homeostatic temperature balance.
In conclusion, the factor that alters a planet’s surface temperature is its atmosphere.

Answer:
The change in internal energy is zero.
(a) is correct option
Explanation:
Given that,
Work done W = -400 J
The First law of thermodynamics is law conservation of energy
Law of conservation energy is defined the total amount of energy is constant in isolated system.
The energy can not be created and destroyed but the energy can be changed from one form to other form.
The First law of thermodynamics is given by
Where,
W = work done by the system or on the system
= Total internal energy
Q = heat
In isothermal process, the temperature is constant
The energy can not be change and the internal energy is the function of temperature.
So, The internal energy will be zero .
Hence, The change in internal energy is zero.
There are a lot.
Some of them are
Gamma radiation
X-ray radiation
Ultraviolet radiation
Visible radiation
Infrared radiation
Microwave radiation
