Answer:
a) is the speed of each proton
b)
Explanation:
Given:
radius of path of motion,
we know charge on protons,
magnetic field strength,
we've mass of proton,
a)
From the equivalence of magnetic force and the centripetal force on the proton:
where:
v = speed of the proton
is the speed of each proton
b)
Now the centripetal force on each proton:
Answer:
369.84 W
Explanation:
= Mass flow rate = 10.62 kg/s
v = Velocity of wind = 8 m/s
Power is given by
The power supplied is 339.84 W
If 30 W of this power is wasted that means 339.84+30 = 369.84 W is required
Kinetic energy = 1/2 mv^2
1/2 x 50 x 2.6^2
= 169J
Answer:
Explanation:
The figure is not provided and we don't know the force applied to the books.
Therefore, here we are going to assume the force applied is 3 N:
F = 3 N
We can find the acceleration of the stack of books by using Newton's second law of motion, which states that the net force on an object is equal to the product between its mass and its acceleration:
where
F is the force
m is the mass
a is the acceleration
In this problem we have
m = 1.5 kg is the mass of the books
Therefore, the acceleration is:
-3, because you have to subtract
