Answer:
By teh way is isn't it question of law or science and the picture is of what electric light or not I have read it so I was asking isn't is question of science
Answer:
This whole concept depends on the depends on the direction of propagation of the surface wave or displacement of wave such that if its in direction of wave velocity its said to features of longitudinal wave and if its in direction at 90° to wave velocity its said to have transverse features
A) 
The angular acceleration of the wheel is given by

where
is the initial angular velocity of the wheel (initially clockwise, so with a negative sign)
is the final angular velocity (anticlockwise, so with a positive sign)
is the time interval
Substituting into the equation, we find the angular acceleration:

And the acceleration is positive since the angular velocity increases steadily from a negative value to a positive value.
B) 3.6 s
The time interval during which the angular velocity is increasing is the time interval between the instant
where the angular velocity becomes positive (so,
) and the time corresponding to the final instant
, where
. We can find this time interval by using

And solving for
we find

C) 2.4 s
The time interval during which the angular velocity is idecreasing is the time interval between the initial instant
when
) and the time corresponding to the instant in which the velovity becomes positive
, when
. We can find this time interval by using

And solving for
we find

D) 5.6 rad
The angular displacement of the wheel is given by the equation

where we have
is the initial angular velocity of the wheel
is the final angular velocity
is the angular acceleration
Solving for
,

The radio because u arent pushing as many watts out and it wont pass through as much
Answer:
The correct answer is the Convex lens. An image is formed when a ray of light coming from a point intersects at another point. The image is formed by the real intersection of light. The image is formed by the virtual intersection of Light.
