Explanation:
Volume can be found by dividing the mass by the density.
The mass is 100 grams and density is 0.920 grams per cubic centimeters.
Therefore,
Substitute the values into the formula.
Divide. Note that the grams, or "g" will cancel each other out.
The volume of the ice cube is 108.697652 cubic centimeters.
Answer:
Explanation:
For free body diagram see attached sheet .
W is weight of steel girder acting at the middle point of its length . T is tension in the cable .
OB = √ ( 12² - 2² )
= 11.83 m .
OC = 11.83 / 2 = 5.915 m
Taking moment of tension T and weight W about point O
W x OC = T x OB
22 x 5.915 = T x 11.83
T = 22 x 5.915 / 11.83
= 11 kN
Considering forces acting in vertical direction and equating forces in opposite direction
T + R = W
R = W - T
= 22 - 11 = 11 KN
So force of grinder on the ground = R
= 11 KN.
