Answer:
Explanation:
The motion of the vehicule on a highway curve can be modelled by the following equation of equilibrium:
The maximum speed is:
Answer:
The scattering angle is 0.80
Explanation:
As we know
Wave length = h/mc (1-cos α) --1
W = mc^2
m = E/c^2
Substituting this in equation 1 we get
Wavelength = hc/E (1-cos α)
Substituting the given values, we get -
0.95*10^-9 = [(6.626 *10^-34 * 2.998 *10^8)/5.111*1000*1.6*10^-19} (1-cos α)
(1-cos α) = 1.14 *10^-10
cos α = 1- 1.14 *10^-10
α = 0.80
Answer:
1.
2.
Explanation:
1. Electrostatic force is given as:
where k = Coulombs constant
q = charge of first charge
Q = charge of the second charge
r = distance between them
From the question:
F = 100 N
q =
r = 0.01 m
We need to find Q.
From the formula of force, we have that Q is:
This is the charge, Q, of the second charge.
2. From the question:
F = 2 N
q =
r =
We need to find Q.
Using the same formula for Q as in 1. above, we have that:
This is the charge, Q, of the second charge.
Answer:
Yes it would be different on Earth and the moon
To determine the amount of electrons in a given charge we need to remember that the charge of an electros is:
coulombs.
Now, if we have a given amount of charge an we want to know how many electrons are in the charge we divide it by the charge in the electron. In this case we have:
Therefore we have:
We know that for each step the worker collects -50nC, this is the same as collecting:
electrons. Now, that we know this we divide the maximum amount of charge the component can take by the electrons in each step:
Threfore the worker can take 3 complete steps before touching the component
