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:
45 takes less energy and is less stronger light than a 60 watt bulb, but a 60 watt bulb is stronger and takes more energy.
Explanation:
Answer:
ANGLE is 35.3 degree celcius
Explanation:
Given data:
mass m and 3m
initial speed Vi
particle with mass m is moving toward left while particle with mass 3m is moving toward right
By using conservation of momentum :
conservation of energy :
After collision, particle with mass m moves at right angles, thus by considering conservation of momentum in x & y direction,
x direction :
y direction :
subsitute these value in energy conservation
35.3 degree from x-axis
A compound is combining two or more substances chemically and it’s pure with a new substance forming, a mixture is combing two or more substances into one physically its impure and no new substances form
If your keg is not moving the only energy your leg can have is Potential energy.
