There was more force applied therefore there was more movement. Hope this helps.
Answer:
c. slow the flow of heat from inside the house to the outside.
Explanation:
Thermal insulation not completely stops the flow of heat but slow down the process of flowing of heat from inside the house to the outside.

Time taken to complete one revolution is .
Convert time from days into seconds.
The expression for magnitude of earth velocity is,
Substitute for , for .
Further solved,
Explanation | Common mistakes | Hint for next step
Time taken to complete one resolution is 365 days. Convert time from days into seconds. Radius of earth orbit around the sun is given. Velocity is circumference of orbit upon time taken in one resolution. Calculate the magnitude of earth velocity. Change unit of velocity to

Answer:
Explanation:
Let's analyze the situation presented in order to know which answer is correct.
When the stick collides with the puck, it exerts a force for a certain time and discants. / After this time the horizontal force decreases to zero and the disk continues to move by the action of the initial velocity on the x axis and the acceleration of gravity on the y axis.
Therefore, after the collision, the only force that acts on the disk is the gravitational attractive force (WEIGHT), directed on the axis and in a negative direction.
The correct answer is:
C) Since there is no frictional force exerted on the puck, a normal force is not exerted on the puck, but the gravitational force is exerted on the puck
