Answer:
See below ~
Explanation:
Part (a) :
We can say a body is in uniform acceleration if the acceleration of the object remains constant with respect to time throughout its motion.
Part (b) :
We can say a body is non-uniform acceleration if the acceleration of the body varies with respect to time throughout its motion.
Answer:
<h2>Your skull protects the most important part of all, the brain. You can feel your skull by pushing on your head, especially in the back a few inches above your neck.</h2>
Explanation:
Answer:
1.
-Deflection force
2.q-Charge
3.v-Velocity of the charge
4.B-Perpendicular magnetic field strength
Explanation:
We are given that magnetic deflection

We have to match each symbol in formula with what it represents.
In this formula
Deflection force
q=Charge of particle
v=Velocity of charge
B=Perpendicular magnetic field strength
Therefore,
1.
-Deflection force
2.q-Charge
3.v-Velocity of the charge
4.B-Perpendicular magnetic field strength
Answer:
Red line is reflected ray.
Explanation:
According to the given figure, the blue line represent the incident ray. It strikes the surface and reflection occurs. The dotted line shows normal.
After reflecting the surface, the ray of light is reflected. Red line shows the reflected light.
In this case, the laws of reflection follows i.e. the angle of incidence is equal to the angle of reflection.
Answer:
Juan and Kuri complete one revolution in the same time, but Juan travels a shorter distance and has a lower speed.
Explanation:
Since Juan is closer to the center and Kuri is away from the center so we can say that Juan will move smaller distance in one complete revolution
As we know that the distance moved in one revolution is given as

also the time period of revolution for both will remain same as they move with the time period of carousel
Now we can say that the speed is given as

so Juan will have less tangential speed. so correct answer will be
Juan and Kuri complete one revolution in the same time, but Juan travels a shorter distance and has a lower speed.
