Try drawing the ball in motion by using arrows to point which direction itll go.
Answer:1.6 kJ
Explanation:
Given
mass of truck
speed of truck
We know kinetic Energy is the energy possessed by a moving body such that its value is given by product of mass and square of speed.
Answer:
(a). Index of refraction are = 1.344 & = 1.406
(b). The velocity of red light in the glass 2.23 ×
The velocity of violet light in the glass 2.13 ×
Explanation:
We know that
Law of reflection is
Here
= angle of incidence
= angle of refraction
(a). For red light
1 × = ×
= 1.344
For violet light
1 × = ×
= 1.406
(b). Index of refraction is given by
= 1.344
2.23 ×
This is the velocity of red light in the glass.
The velocity of violet light in the glass is given by
2.13 ×
This is the velocity of violet light in the glass.
The correct answer is
<span>the flux increases because the magnitude of b increases.
In fact, the magnetic flux is given by
</span>
<span>Where B is the intensity of the magnetic field, A the area enclosed by the coil and </span>
the angle between the direction of B and the perpendicular to the area A.
We can see that since in the problem the intensity of B increases, and the direction remains unchanged, then the magnetic flux increases as well.
