the number of neutrons may b 21
To solve this, you’d multiply 55 by 4, because he is travelling 55 miles every hour, for four hours, which means 55 miles every hour. The answer would be 220.
Answer:
The moment is 81.102 k N-m in clockwise.
Explanation:
Given that,
Force = 260 N
Side = 580 mm
Distance h = 370 mm
According to figure,
Position of each point



We need to calculate the position vector of AB


We need to calculate the unit vector along AB


We need to calculate the force acting along the edge


We need to calculate the net moment

Put the value into the formula




Put the value into the formula


Negative sign shows the moment is in clockwise.
Hence, The moment is 81.102 k N-m in clockwise.
