Answer:
Explanation:
The centripetal force is given by:
Here m is the body's mass in which the force is acting and 
is the centripetal acceleration:
Here v is the speed of the body and r its radius. The speed is given by:
Replacing (3) in (2):
Replacing (4) in (1) and solving for f:
Answer:
- 1100 J heat flows out
Explanation:
dW = - 1600 J (as work is done on the gas)
dU = 500 J
dQ = ?
According to the first law of thermodynamics
dQ = dU + dW
dQ = 500 - 1600
dQ = - 1100 J
As heat is negative so it flows out.
Answer:
it should be -2m/s
Explanation:
Because it is going down from minutes 6-8. And down in most cases means negative. And since it is going down 2 it should be -2m/s.
Hope this helped!!
.15 km. It goes in this way from largest to least: Kilometers, Hectometers, decameters, meters, decimeters, centimeters, and finally millimeters. When you are going up in measures you move the decimal point one space to the left for each measure you pass. It is vice-versa for going down these measures plz mark brainliest.
It is Tension as the other 3 answer choices would not make sense. Compression would mean you are pressing the rock on both sides or in this case, pushing it into the dirt. It can't be nuclear force as you are pulling out a rock. Air resistance would not make sense either as there is no air involved in the scenario at all.
