Answer: ethanol which will dissolve in both water (a polar solvent) and gasoline (a non-polar solvent)
Explanation:
Answer:
53.5 N
Explanation:
Vertical component of the F force 50 sin30 = 25 N upward
force of gravity = m g = 8 * 9.81 =78.5 N Downward
NET downward force by block on table = net upward force exerted by table = 78.5 -25 =53.5 N
Given :
Mass of box , m = 250 kg.
Force applied , F = 285 N.
The value of the incline angle is 30°.
the coefficient of dynamic friction is 
.
To Find :
The speed with which the box is moving with, assuming it takes 4 seconds to reach the top of the incline.
Solution :
Net force applied in box is :
Acceleration , 
.
By equation of motion :
Therefore, the speed of box is 12.04 m/s.
Hence, this is the required solution.
