i think the stream with the steep slope but i'm not entirely sure.

2 cups of the same side are filled to the brim with clear liquids cup a hold water cup be contains alcohol your teacher challenges you to figure out which cup How to water because of your grade science knowledge you know that all substances have their on specific properties you and your lab partner and I an ice cube in each cup ice floats in one like what do you predict it is the water and I sinks in the other like would you predict the liquid is alcohol what property of matter do used to identify liquid

Answers

The property is smell

Answer:

You used the property of density.

Explanation:

The ice cube floats in water because it is less dense and sinks in alcohol because it is more dense than the alcohol.

How fast will a cart be moving if a force of 200 N is applied to a 50 kg cart for 10 sec?

Answers

Acceleration = (force) / (mass)

If there is no friction . . .

Acceleration = (200N) / (50 kg) = 4m/s²

Change in speed = (acceleration) x (time) = (4 m/s²) x (10 sec) = 40 m/s

Final speed = (speed of the cart before the force began) + (40 m/s more)

(That's about 89 mph faster than the cart was moving before the force started.)

I'm assuming that the cart starts from rest.

Initial velocity (vi): 0 m/s
Final velocity (vf): ?
Acceleration (a): ?
Force (F): 200 N
Mass (m): 50 kg
Time (t): 10 s

F= ma
200 N= (50kg)(a)
a= +4 m/s^2

a= (vf-vi)/t
+4 m/s^2= (vf - 0m/s)/10s
vf= 40 m/s

Answer: the cart will be moving 40 m/s.
