(i) • there is force applied to an objects
• the object moves
• the object moves in the same direction as the direction of the force
(ii) workdone = force x distance
= 23 x 34
= 782Joules
Potential energy is stored energy because it has the potential to do something which laters turns into kinetic energy which is the moving energy.
Answer:
c. Moon A is four times as massive as moon B
Explanation:
Let's assume the:
- mass of the object =
- mass of the moon A =
- mass of the moon B =
- distance between the center of masses of the object and moon B =
According to the given condition the object is twice as far from moon A as it is from moon B
- ∴distance between the center of masses of the object and moon B =
<u>As we know, gravitational force of attraction is given by:</u>
<em>According to the condition</em>
Force on m due to
Force on m due to
Answer:
F = M a is the vector equation involved
F = T - M g are the forces acting on the elevator (scalar equation)
T - M g = M a
T = M (a + g) remember this a scalar
If a is slowing down then it must have a positive acceleration upwards
Therefor the tension in the cable must be greater than zero
When the tension increases to M g, a has increased to zero
For a to be zero, no acceleration, T = M g
Lifting hands and the down by one student at a time best describe the presentation of the transverse wave by students. Option D is correct.
<h3>
What is a Transverse wave?</h3>
- The wave in which the oscillation of particles is is perpendicular to the direction of energy transfer.
- The students can make a transverse wave by raising their hands up and then down, one student at a time.
- The raised hand represents the oscillation of particles while the sequence of the raising hand represents the direction of energy transfer.
Therefore, lifting hands and the down by one student at a time best describe the presentation of the transverse wave by students.
