Answer:
All the three quantities will have non zero joules.
Explanation:
At the initial position of rest the system will have only gravitational potential energy while the other 2 quantities will be zero.
when the system reaches a height (y-h) only kinetic energy will be zero while the other 2 quantities will be non zero
At the position of (y-h/2) all the 3 quantities will be non zero.
Answer:
The right option is C. i.e L
Explanation:
Dimension of a quantity is the collection of the indexes of each of the fundamental quantities contained in it.
Therefore, to get the dimension of A in the equation
X=Asin(2(pi)ft)
Making A the subject of the formula
A = X / (sin(2(pi)ft)
Since sin(2(pi)ft which is a trigonometric function does not have a dimension
A = L
The dimension of A is L
Answer:
1.47*10^{-8}s
Explanation:
You first calculate the distance traveled by the electron:
Next, you calculate the relative speed as measure by an observer in the positron, of the electron:
with this relative velocity you calculate the time:
The answer is 50 kg plz mark as brainliest
I believe it always acts in the direction opposite to that of the object in motion, so if the force was applied to the left then friction acts in the right
hope that helps
