Answer:
The magnitude and direction of the resultant is 8.66 N and south of East.
The magnitude and direction the equilibrant is 8.66 N and North of West respectively.
Explanation:
Let
= Angle between P and Q =
Magnitude of resultant
Direction is given by
The magnitude and direction of the resultant is 8.66 N and south of East.
The magnitude and direction the equilibrant is 8.66 N and North of West.
Answer:
Inside an atom are protons, electrons and neutrons. The protons are positively charged, the electrons are negatively charged, and the neutrons are neutral. Therefore, all things are made up of charges. For example, if you rub your shoe on the carpet, your body collects extra electrons.
Explanation:
Answer:
a)
m/s
b)
Angular frequency =
Explanation:
As we know
q is the charge on the electron = C
B is the magnetic field in Tesla = T
r is the radius of the circle = m
mass of the electrons = Kg
a)
Substituting the given values in above equation, we get -
m/s
b)
Angular frequency =
Answer:
a.) F = 3515 N
b.) F = 140600 N
Explanation: given that the
Mass M = 74kg
Initial velocity U = 7.6 m/s
Time t = 0.16 s
Force F = change in momentum ÷ time
F = (74×7.6)/0.16
F = 3515 N
b.) If Logan had hit the concrete wall moving at the same speed, his momentum would have been reduced to zero in 0.0080 seconds
Change in momentum = 74×7.6 + 74×7.6
Change in momentum = 562.4 + 562.4 = 1124.8 kgm/s
F = 1124.8/0.0080 = 140600 N
