i don't have any answer without the options
Explanation:
Where is the pic
Answer: Given mass of man = 85kg
Distance crate was pushed = 4m
Force exerted on crate = 500N
Angle inclined = 20°
Let Total force exerted Ft = (mg * sin(20)) + 500
Ft =( 85*9.81* sin20°) + 500
Ft = 758N
Work done Wd = Ft * distance
Wd = 785 * 4 = 3.14 * 10^3J
Answer:
The answer is option B: the ball´s force on the bat
Explanation:
Using Newton's third law (action and reaction) that says: If two bodies interact the force of one exerts on the other is of equal magnitude, direction and opposite direction
Therefore, if the bat hits the ball (action), the ball (reaction) with a force on the bat of equal magnitude, but opposite direction
Answer:
The height of the tower will be 35.714 m
Explanation:
We have given gauge pressure 
Density of water 
We have to find the height of the tower h
We know that gauge pressure is given by 
So the height of the tower will be 35.714 m
Refraction - <span>the fact or phenomenon of light, radio waves, etc., being deflected in passing obliquely through the interface between one medium and another or through a medium of varying density.</span>
