It should be 12 N. the force of the book on the table should be the same as the force of the table on the book.
Answer:
B
Explanation:
The net force is the force between action and reaction and when this forces are not the same an acceleration is spurred.
Answer:
Hi,
It states that the in linear systems, two or more stimuli cause a net stimulus that is equal to the sum of the individual responses. Applying the principle of superposition to waves, two waves of the same magnitude at a point in space add up to form a resultant displacement at that point which equals the sum of the two vectors.
Explanation
When two or more waves meet, they can interact to form a bigger wave or cancel out. In both cases, the resultant effect is caused by a combination of the two. This principle is applied in noise cancelling headphones that capture and cancel the noise around you by playing an opposite sound that ensures the cancelling of the destructive noise.
Best wishes!
We can solve for the acceleration by using a kinematic equation. First we should identify what we know so we can choose the correct equation.
We are given an original velocity of 24 m/s, a final velocity of 0 m/s, and a time of 6 s. We and looking for acceleration (a) in m/s^2.
The following equation has everything we need:
So plug in the known values and solve for a:
0 = 24 + 6a
-24 = 6a
a = -4 m/s^2
Answer:
Explanation:
frequency of radiation
= 8.54 x 10¹⁴
wave length = 3 x 10⁸ / 8.54 x 10¹⁴
= .3513 x 10⁻⁶ m
= 3513 A
Energy of this wave OR energy of each photon in eV
= 12375 / 3513
= 3.52 eV
the minimum amount of energy required = 3.52 eV.
