Considering the magnetic force is providing the centripetal force,
we get, mv^2/r = qvB
so, r = mv/qB
as the Kinetic energy, K of the particle is given by.5mv^2
so, v = sqrt(2K/m)
substituting the in radius equation,
<span>r = m*sqrt(2K/m)/qB
r = sqrt(2Km)/qB</span>
Answer:
Para que la masa del proton sea 1 kg se requieren alrededor de 6x10²⁶ protones.
Explanation:
Sabiendo que la masa del proton es:
Entonces para que la masa sea 1 kg tenemos:
En donde N es el número de protones.
Por lo tanto, para que la masa del proton sea 1 kg se requieren alrededor de 6x10²⁶ protones.

Answer:
122.45 meters
Explanation:
G.P.E is m*g*h
The mass is 80 kg and gravity is 9.8 m/s². The G.P.E is 96000 J
Plug those in to the equation
96000=80*9.8*h
Multiply 80 and 9.8 to get 784
96000=784h
Divide by 784 on both sides to get h=122.45 meters

The speed of the car at the top of the hill is 14m/s
<u>Explanation:</u>
given that
Initial velocity u of the car=0 m/s
The distance can be determined by finding out the difference between the elevation of the first slope and second slope.
elevation of the first slope=26 m
elevation of second slope=16m
distance s=26-16=10 m
acceleration due to gravity g=9.8 m/s2
speed of the car at the top of the hill can be determined by using the equation
speed of the car at the top of the hill is 14m/s
The initial velocity of the potato is 54.41 m/s.
The given parameters:
- <em>Mass of the potato, m = 0.34 kg</em>
- <em>Mass of the cart, m = 5.0 kg </em>
- <em>Velocity of the recoil, u₂ = 3.7 m/s</em>
<em />
The initial velocity of the potato is calculated by applying the principle of conservation of energy as follows;
Thus, the initial velocity of the potato is 54.41 m/s.
