Answer:
C
Explanation:
Without thinking, the answer is C.
The problem is with D. Of course it is going to depend on the transparency. If the material is a rock, then the light won't go through, and n >>>1. I don't think you are intended to think that way, but I sure wish D wasn't there. I'd answer C, but be prepared to see it come out as D.
To resolve point A and B we need the concepts related to conservation of momentum (By collision) and Kinetic Energy. Conservation of momentum is given by the equation,
Our values in the statment are:
Part A) As it is in an icy intersection, there is two different components (x,y) then,
Then the magnitude is,
Part B) To obtain the Kinetic Energy Loss we need to use its equation, which is given by,
The final energy is given by,
Then the change in Kinetic Energy is
<em>There was a loss of KE of 183.02kJ</em>
Answer:
it resembles volleyball because its "played as a variation of volleyball
Explanation:
Catchball — a easier version of volleyball in which the players catch and throw the ball rather than hit it. Volleyball — a game for two teams of six players, in which a large ball is hit by hand over a high net, the aim being to score points by making the ball reach the ground on the opponent's side of the court.
Answer:
<h2>A. 180 miles</h2><h2>B. 60 miles</h2><h2 />
Explanation:
In this problem, we are required to solve for the total distance that the car travelled. and the displacement
A) the distance travelled by car
this can be gotten by summing all the distances the car has travelled.
i,e total distance= 60 miles+120 miles
total distance= 180 miles
B) the displacement of the car
the displacement can be gotten by subtracting the final distance from the initial distance
final distance = 120 miles
initial distance= 60 miles
displacement= 120-60= 60 miles
Because it generates enough momentum to keep the train going with out really having to speed up
