A mirror only mists because the air is hot and the mirror is cold and if it is heated than the steam wont make the mirror become misty....
hope this helps :D
The existence of atmosphere increases the average planetary temperature by more than 15°C, due to the greenhouse effect of some atmospheric compounds. The most important of them are water vapour (H2O), ozone (O3), carbon dioxide (CO2), and methane (CH4).
So this form of energy is gravitational potential, which is defined as mass*height*gravity so if we use gravity as 10 m/s^2 to keep it simple we can do 150kg*10m*10m/s^2 and we get a total of 15,000 joules
Answer: C. 1.4 10-11 N up
Explanation:
The magnetic force, F on a charge q moving with velocity v in a magnetic field B at an angle θ is given by:
F = q v B sin θ
Charge of proton, q = 1.6 × 10⁻¹⁹ C
Strength of magnetic field, B = 3.4 T pointing outwards
velocity of the proton, v = 2.5 × 10⁷ m/s towards left
Magnetic force is given by:
F = 1.6 × 10⁻¹⁹ C× 2.5 × 10⁷ m/s ×3.4 T× sin 90 = 13.6 × 10⁻¹² N = 1.4 × 10⁻¹¹ N up
The direction of the force is given by Lorentz Right hand rule. The fingers point magnetic field, the thumb points towards velocity, then the force on the proton is given by the direction perpendicular to the palm.
The magnetic field acts outwards with velocity of the proton towards left. The force would act perpendicular to the two -upwards.
C. This is a direct current

What is schematic Current?</h3>
An electrical schematic is a diagram that shows how all of the wires and components in an electronic circuit are connected.
The ability to read electrical schematics is a really useful skill to have. To start developing your schematic reading abilities,
it’s important to memorize the most common schematic symbols.
Each physical component (i.e resistor, capacitor, transistor) has a unique schematic symbol.
