Answer:
The magnitude of the tension in he string is equal to the magnitude of the weight of the object.
Explanation:
According to the Newton's 1st law, An object will remain at rest or in uniform motion in a straight line unless acted upon by an unbalanced force.
In here, the elevator is moving with a constant speed. So the object must have the equal constant speed. Which means, it has a uniform motion. According to Newton's 1st law, the total unbalanced force on the object must be zero . As we know, there are only two forces are on the object and they are,
The tension in string(T) , The weight of the object(W) .
∴ F = 0
T - W = 0
So to balanced those forces, the magnitude of the tension in the string must be equal to the magnitude of the weight of the object.
D.) It is an "Element".
[ Element cannot be separated by any means ]

The vertical height of the given plane is 4.9 m.
The given parameters:
- <em>speed of the object at the bottom of the ramp, v = 9.8 m/s</em>
The vertical height of the plane is calculated by applying principle of conservation of mechanical energy as follows;
Thus, the vertical height of the given plane is 4.9 m.

Argon come from the air. It is a noble gas present in atmosphere. The percentage of argon in air is about 0.93%. Naturally, it is a colorless and odorless gas. When electrifies it gives a blue-green glow. Argon laser is used in field of medicine and surgery.
