Answer:
Part a)
Part b)
Since on the block wedge system there is no external force in horizontal direction so the Center of mass will not move in horizontal direction but in vertical direction it will move
so displacement in Y direction is given as
Explanation:
PART A)
As we know that there is no external force on the system of two masses in horizontal direction
So here the two masses will have its momentum conserved in horizontal direction
So we have
Also we know that here no friction force on the system so total energy will always remains conserved
So we have
now we have
so we have
and another block has speed
Part b)
Since on the block wedge system there is no external force in horizontal direction so the Center of mass will not move in horizontal direction but in vertical direction it will move
so displacement in Y direction is given as
Answer:
The maximum torque is 
Explanation:
From the question we are told that
The length of the wire is 
The current flowing through the wire is 
The magnetic field is 
The maximum torque is mathematically evaluated as
Where 
is the magnetic dipole moment which is mathematically represented as
Where 
is the number of turns which from the question is 1
substituting values
Now
The ball is traveling in the + x direction at 8m per second. After 20 seconds it has moved 160m forward from the spot where it was tossed.
B. 60 cm
All parallel light rays are bent through the focal point of a convex lens, so the rays from the flashlight 150 cm above the floor must go through the same point on the principal axis as the rays from the flashlight 120 cm above the floor. The location of the focal point does not change when the position of the object is moved either vertically or horizontally.
Hope this helps !
Due to damming the water it will not flow as fast and since it wont flow as fast it will cause the water level to rise.
