Answer:
0.114m
Explanation:
From the general expression for the radius of the proton's resulting orbit, we have
where q is is the charge of the proton 
m is the mass of the proton 
B is the magnetic field 
and v i the speed.
to determine the speed, we use the expression
Kinetic Energy=
where <em>V </em>is the voltage value i.e 1.0kv
and v is the speed
Hence, from simple rearrangement we have the speed v to be
if we substitute value, we have
carrying out careful arithmetic we arrive at
.
using the value for the speed in the expression for the radius of the orbit as stated earlier, we have
Answer:
Speed, v = 7.83 m/s
Explanation:
It is given that,
Length of the bridge, l = 5 m
The road on the far side is 2.0 m lower than the road on this side, x = 2 m
The horizontal distance covered by the car is 5 meters and the vertical distance covered by the car is 2 meters.
Initial speed of the car, u = 0
Let t is the time taken by the car . Using the second equation of motion as :
For vertical distance :
Let v is the velocity to jump the stream. It is given by :
Horizontal distance, d = 5 m
v = 7.83 m/s
So, the car should travel with a speed of 7.83 m/s. Hence, this is the required solution.
Answer:
Force has a direct relationship to mass and acceleration. Newton's Second Law, force equals mass times acceleration (F=MA), illustrates their general relationship in an equation.
Explanation:
Relationships to remember:
- <u>Force</u> and <u>acceleration</u> have a direct relationship, meaning if force increases, acceleration will also increase and vice versa
(Ex: The harder you push a box, the faster it will move)
- <u>Mass</u> and <u>acceleration</u> have an inverse relationship, meaning if mass increases, acceleration will <em>decrease</em> and vice versa
(Ex: If you add more furniture in the back of a moving company truck, the truck will move slower than it did before the furniture was added)
- <u>Force</u> and <u>mass</u> have a direct relationship, meaning if mass increases, force will also increase
(Ex: You will need to exert less force to lift a 5-pound weight than a 10-pound weight)
And of course, Newton's Second Law, F=MA sums all of this up in 3 letters and a symbol! If you have any more questions about this problem, please comment on my answer :)
