Answer:
1.9 m.
Explanation:
Three complete waves in the length of 5.7 m
The distance traveled by one complete wave is called wavelength.
Thus, the distance traveled by one wave = 5.7 / 3 = 1.9 m
Thus, the wavelength is 1.9 m.
Answer:
The answer is explained below.
Explanation:
All the point on the disk has same angular acceleration. Here, the point P is at the midway between the center and the rim of the disk and the point Q is at rim of the disk.
So, the distance of the point Q from the axis is twicee the distance of the point P from the axis.
<em>Rp - R</em>
<em>Rq - 2R</em>
The linear acceleration is
α2 - Rα
So, the linear acceleration of Q is twice as great as the linear acceleration of P.
The speed of the particle when it is in the circular motion depends on the radius of the particle.
In this case, the speed of point Q is twice the speed of point P.
45 because you see it in a hot min.
Answer:
The focal length is 15.549 cm
The power of the lens is 0.0643 D
Solution:
As per the question:
The near point is 50.0 cm
Distance of the glasses from the eyeball, d = 2.00 cm
The near point of a normal human eye is 25 cm
Now,
The image distance, v' = 50.0 - 2.00 = 48.0 cm
The object distance, u' = 25.0 - 2.00 = 23.0 cm
Now, using the Lens maker formula to calculate the focal length:
f = 15.549 cm
Now, the power of the lens in diopters is given by:
Answer:
80 N
Explanation:
The windshield is a part of the car and the bug hits it so the bug hits the car. they both are in opposite directions so their total force will be 80N
