Answer:

Explanation:
As we know that the resistance of the wire is given as

now we know that both the bulbs are getting 12.5 A current in their branches
so total current in the circuit is given as


so we have total voltage across the wire is given as


now the load voltage is given as



Answer:
The process known as weathering breaks up rocks so that they can be carried away by the process known as erosion. Water, wind, ice, and waves are the agents of erosion that we
Explanation:
Agents are Water, wind, ice, gravity and waves.
Force = Mass x Acceleration
This is Newton's Second Law of Motion
Anyway,
450 = M x 15
450/15 = M
30kg = M
Answer:
(a) 0.34 cm
(b) 1.32 cm
Explanation:
Given that, 

And the length of objective lens in a microscope

And we have d of the eyepiece is 25 cm.
(a) Focal length of the objective is,

Therefore, objective lens's focal length is 0.34 cm.
(b) Focal length of an eyepiece,

Therefore, eyepiece's focal length is 1.32 cm.
