Answer:
1.1655 N
Explanation:
Given that,
Initial speed, u = 25 m/s
Final speed, v = 26 m/s
Time taken, t = 54 s
So, Applying equation of motion as:
According to the Newton's second law of motion:-
Mass = 63 kg
So,
<u>Force = 1.1655 N</u>
<span>The electric field is inversely proportional to the distance.</span>
Low. Copper has relatively high conductivity.
Light intensity and distance is
interrelated. When the distance changes, the intensity of light changes. This relationship
is called inverse-square relationship. The inverse-square relationship refers
to the fact that when distance changes, light intensity also changes: inverse
because when distance decreases, light density increases and when distance
increases, the latter decreases; square refers to the fact that light intensity
and distance is not a one-to-one relationship.
Answer:
Contact glasses.
Explanation:
-Anytime you put on a pair of glasses, or see light bend through a glass of water or a prism, this rule is in action.
-In short, Snell's law governs the angle by which electromagnetic radiation such as light refracts, or changes direction, as it passes from one material to another and slows down.
