Answer and Explanation:
Parallax method is used for finding the distance of objects in space there are two types of parallax method that is stellar parallax and trigonometric parallax.The disadvantage of using parallax method is that it can can not reach so far in the Galaxy due to this reason parallax method is generally not used for measuring distance in galaxy.
Answer:
Sorry for being late. It is...
A.) X: Load, Y: Fulcrum, Z: Lever
1 mA = 0.001 A
Therefore, 5 mA = 0.001 * 5
=0.005 A
Resistance = voltage / current
= 100 / 0.005
= 20000 ohms
Current = voltage / resistance
= 25 / 20000
= 0.00125 A (or) 1.25 mA

Answer: 
Explanation:
Given
Mass 
Spring constant 
Compression in the spring 
When the mass leaves the spring, the elastic potential energy of spring is being converted into kinetic energy of mass i.e.

The kinetic energy of the mass is 1.102 J.
