If we will connect the resistors 2ohms, 3ohms, 5ohms in series and the 10ohms resistance parallel then we get equivalent resistance of 5 ohms.
The equivalent circuit is,
R equivalent for the series connection is,
The equivalent resistance is 5 ohms.
So your friend is saying true.
A reference point is important in determining motion because in order to say that something is moving, you need to have something stationary to compare it to.
Answer:
a)the process by which heat or electricity is directly transmitted through the material of a substance when there is a difference of temperature
b)the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat
c)radiation is the emission or transmission of energy in the form of waves or particles through space or through a material medium.
Answer:
The angular speed (in rev/s) when her arms and one leg open outward is 1.161 rev/s
Explanation:
Given;
moment of inertia of a skater with arms out, = 3.1 kg.m²
moment of inertia of a skater with arms in, = 0.9 kg.m²
inward angular speed, = 4 rev/s
The angular momentum of the skater when her arms are out and one leg extended is equal to her angular momentum when her arms and legs are in.
Therefore, the angular speed (in rev/s) when her arms and one leg open outward is 1.161 rev/s
