The correct answer is letter C, regular reflection.
<span>An image seen in a smooth dinner plate is an example of a
regular reflection. This phenomenon only occurs in smooth and polished surfaces.
During this stage light occurs at a certain angle and is reflected back at the
same angle producing reflections in a way like a mirror does this commonly.</span>
Answer:
Net force= 14 units
The object is unbalanced
Explanation:
The net force refers to the sum of all forces applied to an object. However, the direction of force applied determine the net force. In this question, a boy and girl is pulling a heavy crate at the same time.
This means that the force is in the same direction, hence, the net force will be:
F(N) = 7 + 7 = 14 unit
However, since the pull is occuring at the same direction. This means that the object has a net force, therefore, will move in a particular direction. This means that the OBJECT IS UNBALANCED
Answer:
Yes, it will float.
Explanation:
It is given that,
A liquid has a density of 0.85 g/cm³.
We know that, the density of water is 1 g/cm³.
The density of the liquid is less than that of water. If the density of the liquid is less than that of water, it will float in it. Hence, if you pour some of the liquid into a glass of water, it will float.
Answer:
clockwise torque is due to weight of the person + weight of the ladder
Explanation:
As we know that the forces that act on the ladder is given as
1) friction force
2) Normal force at the ends of the ladder
3) Weight of the person standing on the ladder
4) Weight of the ladder
So here we know that our reference point is at the bottom position of the ladder
So we will have
Torque due to weight of the person and weight of the ladder is counter balanced by the torque due to normal force and torque due to friction force
So here we have
clockwise torque is due to weight of the person + weight of the ladder
Answer:
yes
Explanation:
because it has the potential to move
