Answer:
6.0cm
Explanation:
Given
focal length = 15.0cm
object distance = 10.0cm
Required
Image distance v
Using the formula
1/f = 1/u + 1/v
1/15 = 1/10+1/v
1/v = 1/15 + 1/10
1/v = 2+3/30
1/v = 5/30
v = 30/5
v = 6.0cm
Hence the image distance is 6.0cm
Answer:
if the two polarizers have the same direction the transmitted light is 50% of the incident and if the two polarizers are at 90º the transmitted light is zero
Explanation:
The incident light is generally random, that is, it does not have a polarization plane, when the first polarized stops by half, this already polarized light arrives at the second polarizer and the causticity passes
I = I₀ cos² θ
therefore if the two polarizers have the same direction the transmitted light is 50% of the incident and if the two polarizers are at 90º the transmitted light is zero
The force exerted by each team is 30 N. The forces are in the direction opposite to each other.
Force exerted by team 1, 
Force exerted by team 2,
Net force, 
Therefore, net force on the rope is 0 N.
Answer:
prevents pollution, reduces the need to harvest new raw materials, saves energy, reduce greenhouse gas
According to Newton’s second law acceleration= force/mass
So acceleration = 10/2
= 5m/s^2
