Answer:
Multiply the acceleration by the time to obtain the velocity change.
Answer: The control group is the part where you see what happens when you change a variable you want to study/examine. Basically, you need the control group because you need something to see what happens when you change something.
Hope this Helps! :))))
Answer:
C. D.C.
Explanation:
The current that is being described here is D.C. or direct current. It is the D.C. that moves in one direction from negative to positive. May be created by a battery. It is different from the A.C.( alternating current whose polarity changes regularly). It is A.C. that is used in electrical outlets and not D.C.So, the current option is C.
The force acting on the passenger is equal to:
![F=N-mg](https://tex.z-dn.net/?f=F%3DN-mg)
Where N is the normal force and mg is a force of gravity. If a person feels like their weight is increased by 60% at the bottom that means normal force is 60% stronger than the force of gravity:
![N-mg=0.6mg](https://tex.z-dn.net/?f=N-mg%3D0.6mg)
We know that net force must be equal to the centripetal force:
Answer:
2040 m or 2.04 km
Explanation:
The formula to calculate distance is D = v * t
D = Distance
v = velocity
t = time
Now plug and chug
D = 340 m/s * 6.0s = 2040 m = 2.04 km
