Answer:
Option C or the third option.
Explanation: Water is a renewable resource there is so much of it and it just keeps circulating through the system it doesn't run out.
We can calculate the acceleration of Cole due to friction using Newton's second law of motion:

where

is the frictional force (with a negative sign, since the force acts against the direction of motion) and m=100 kg is the mass of Cole and the sled. By rearranging the equation, we find

Now we can use the following formula to calculate the distance covered by Cole and the sled before stopping:

where

is the final speed of the sled

is the initial speed

is the distance covered
By rearranging the equation, we find d:
Answer:
13m/s. is the answer probably but do u have ms gallup too?
Answer:
D = 230.2 Km
Explanation:
let distance between seismograph and focus of quake is D
From time distance formula we can calculate the time taken by the S wave

From time distance formula we can calculate the time taken by the P wave

It is given in equation both waves are seperated from each other by 17.8 sec
so we have
sec
Putting both time value to get distance value

D = 230.2 Km
Answer:
Part a)

Part B)

Explanation:
Part A)
At the top of the hump the force on the rider is
1) Normal force
2) weight
so here we know that




Part B)
At the top of the loop we will have

in order to remain in contact the normal force must be just greater than zero
so we will have
