Answer:
The answer is Option A...
The current through R equals the current through R1
Answer:
The mechanism of energy transport through a medium involves the absorption and reemission of the wave energy by the atoms of the material. When an electromagnetic wave impinges upon the atoms of a material, the energy of that wave is absorbed.
Answer:
d. Test the rods one pair at a time in each possible end‑to‑end orientation until finding a pair that repels; the leftover rod is unmagnetized.
Explanation:
Repulsion is the surest test of magnetisation . If two objects repel each other , they must be magnets . If two objects attract each other , they may not be magnets. In later case , one may be non - magnet. So the last test will help us identify the unmagnetised rod.
The initial velocity of the hockey puck is obtained as 22 m/s.
<h3>What is the frictional force?</h3>
The frictional force of the hockey puck is the force that causes it to stop. Now;
Ff = μmg
Ff = 0. 51 * 0.16 Kg * 9.8 m/s^2
Ff = 0.8 N
Now;
F = mv^2/2x
Where;
m = mass
v = velocity
x = distance
v =√ 2xF/m
v = √ 2 * 47.7 * 0.8 / 0.16
v = 22 m/s
