A) the tension in the string.
Answer: By 47
Explanation: subtract 310 and 263
Answer:
This is because using a long handled requires less force to the center of gravity and makes it easier to rotate than a short handled spanner
<span>Since forces are vector quantities, we must indicate direction using positive and negative values. East will be assigned positive and west will be negative. Friction will act as a negative force since it impedes action. To calculate the net force we sum the vector quantities, as follows. Net force equals 50n which is derived by the following calculation: 300n-220n-30n.</span>
