Answer:
Convection
Explanation:
The method of heat transfer that occurs when particles move through a fluid is called convection.
Conduction is where heat is transferred from one substance to another through direct contact.
Thermal energy is the amount of heat that a substance has.
I hope this helps!
Hi there!
p(a∩b) = 0.
Since a and b are mutually exclusive events, there is no overlap or intersection of events.
These two events CANNOT both occur, so the intersection of p(a) and p(b) does not exist.
Thus, p(a∩b) = 0.
The potential energy of a 2-μc charge at that point in space is joules.
Given,
V=400v, q=2-μc=2*,
U(potential energy)=V*q=400*2*= joules.
<h3>Potential energy</h3>
The energy that an item retains due to its position in relation to other objects, internal tensions, electric charge, or other reasons is known as potential energy in physics. The gravitational potential energy of an object is based on its mass and the distance from the centre of mass of another object. Other common types of potential energy include the elastic potential energy of an extended spring and the electric potential energy of an electric charge in an electric field. The joule, denoted by the sign J, is the SI's definition of an energy unit.
The vectors that are described as gradients of a particular scalar function known as potential can be used to represent these forces, also known as conservative forces, at any location in space.

Answer:
<u>Given </u><u>information:</u><u>-</u>
- Radius of the circular track is <u>636 m</u>
- The time elapsed in the journey is <u>1.5 min or 90 s</u>
- The distance traveled by the cyclist is semi circumference of the circle = <u>πr</u>
The displacement of the cyclist will be shortest distance from his initial to final positions which is nothing but diameter of the circle = 2r
<u>We know that,</u>
- Speed of the cyclist is 22.18 m/s
- <u>Velocity of the cyclist</u> is 14.13 m/s
Thank You :)
Answer is B. Since the number in the inequality is 5, we must be able to include it in the inequality, and therefore must use an “equal to” inequality. Since there are values less than 5, we must be able to include those numbers in the inequality. A greater than sign would therefore not make sense, meaning you must use a less than sign. Combine these two observations and you will find that the graph must be less than or equal to 5.
