Answer:
65 meters to the right.
Explanation:
the shark moves to the right 30 meters and then to the left 15 making his new placement 15. he then moved to the right 50 meters making his new placement 65 meters to the right.
Answer:
When a light wave goes through a slit, it is diffracted, which means the slit opening acts as a new source of waves. How much a light wave diffracts<em> (how much it fans out)</em> depends on the wavelength of the incident light. The wavelength must be larger than the width of the slit for the maximum diffraction. Thus, for a given slit, red light, because it has a longer wavelength, diffracts more than the blue light.
The corresponding relation for diffraction is
,
where is the wavelength of light, is the slit width, and is the diffraction angle.
From this relation we clearly see that the diffraction angle is directly proportional to the wavelength of light—longer the wavelength larger the diffraction angle.
Answer:
Speed, v = 26.5 m/s
Explanation:
It is given that,
The ball hits the ball at an angle of 40 degrees.
Initial height of the ball, h = 1 m
Vertical distance, y = 3.4 m
Horizontal distance, x = 67 m
The trajectory of the particle in projectile motion is given by :
R is the range of projectile.
Putting all the values in above equation as :
R = 71.3 meters
Now using the formula of the range of the projectile as :
Substituting the values in above equation as :
u = 26.5 m/s
So, the speed with which Fred give to the ball is 26.5 m/s. Hence, this is the required solution.
Answer :
It covers 27 meters
