Weight = (mass) x (gravity)
120 N = (mass) x (9.8 m/s²)
Mass = (120 N) / (9.8 m/s²)
Mass = 12.24 kg (B)
D=Vot+1/2at^2
In this case, there is no initial y velocity so the term Vot=0 so d=1/2at^2
acceleration=acceleration due to gravity=-9.8m/s^2
It falls - 22cm or -0.22m
We have - 0.22=1/2(-9.8)t^2
t^2=(-0.44)/(-9.8)
t=sqrt[0.44/9.8]
A line that is falling towards the x axis represents an object that is negatively accelerating, or slowing down. When the line hits the x axis, the object has stopped moving. If the graph continues below the x axis, the object has changed direction and is moving backwards at increasing velocity.
Answer:
cross at many points
Explanation:
According to the diagram it does not shows the real electric field as the electric field does not intersect with each other but according to the given diagram many lines are intersected with each other
So the correct option is C as it would be crossed at many points
Hence, the same would be relevant
Answer:
The induced emf between two end is 
V
Explanation:
Given:
Length of rod 
m
Height 
m
Magnetic field 
T
For finding induced emf,
Where 
velocity of rod,
For finding the velocity of rod.
From kinematics equation,
Where 
initial velocity, 
Put the velocity in above equation,
V
Therefore, the induced emf between two end is V
