The main purpose of the turbine in the turbojet engine is to "<span>compress the air". There is also the added factor of pushing the air, which increases mobility. </span>
Answer:
B. 2.77 x
N
Explanation:
The required force can be calculated by:
F = 
Where F is the force between the particles, K is the coulomb's constant (9 x
),
is the charge on the first particle,
is the charge on the second particle and
is the distance between the particles.
So that:
F = 
= 
= 2.7692 x
The force between the particles is 2.77 x
N.
p=3.0D contact lens is needed to correct his distant vision.
The person is suffering from myopia and hence need a concave lens to correct the defect. The lens should be such that an object at infinity must form its image at the far point.
Hence,f= -32.3cm
= -0.323m
we can define the power of the lens as the reciprocal of its focal length in metre.
The power of lens is the ability to converge and diverge rays of light.
The power of the lens can be obtained as:
p= 1/f
p=1/(-0.323)
p=3.0D
Thus,the power is 3.0D to correct his distant vision.
