Explanation:
the reason for this is that the weight per in is too heavy crushing the snow blower but with the skies the weight is distributed to the point were the snow can support her weight

Explanation:
Given child moves the box with constant velocity over his head .
Force acting on box due to gravity is equal to his weight
Displacement of the box is Perpendicular to the direction of Applied force
Work done is given by
here 
is the angle between Force and displacement which is 
so work done is zero
the answer is true because evaporates can provide an ideal speed racing surface
An uncharged body is a body that has equal magnitude of positive as well as negative charge on it. So as soon as some charged body is placed near it, the charged body induces negative charges on the uncharged body.
Speed = distance/time
Time = 90/60 = 1.5 hours
Speed = 54/1.5
Speed = 36km/h
