1. Giga is the largest
2. Stem-and-leaf
Answer:
momentum
Explanation:
the impulse is equal for both carts, the momentum for both carts is zero both before the string is cut and after it is cut
Answer:
0.1308
Explanation:
To keep the rider from sliding down, then the friction force
must at least be equal to gravity force 


where μ is the coefficient, N is the normal force acted by the rotating cylinder, m is the mass of a person and g = 9.81 m/s2 is the gravitational acceleration.
According to Newton's 3rd and 2nd laws, the normal force would be equal to the centripetal force
, which is the product of centripetal acceleration
and object mass m

Therefore


The centripetal acceleration is the ratio of velocity squared and the radius of rotation

Therefore

Answer:
The speed on boat in still water is
and the rate of the current is 
Explanation:
Since speed , 
Therefore speed of motor boat while traveling upstream is

and speed of motor boat while traveling downstream is
Let speed of boat in still water be
and rate of current be 
Therefore
----(A)
and
------(B)
Adding equation (A) and (B) we get

=>
------(C)
Substituting the value of
in equation (A) we get

Thus the speed on boat in still water is
and the rate of the current is
