Answer:
d. 2m to the right of the pivot
Explanation:
m1 = m
m2 = 0.5m
d1 = 1m
d2 = ?
from principle of moment,
CWM = ACWM
m × 1 = 0.5m × d2
d2 = m/0.5m
= 1/0.5
= 2m
The 2nd child will have to sit 2m to the right
The turning effect of a force is known as the moment. It is the product of the force multiplied by the perpendicular distance from the line of action of the force to the pivot or point where the object will turn.
The principle of moments states that when in
equilibrium the total sum of the anti clockwise
moment is equal to the total sum of the
clockwise moment.
When a system is stable or balance it is said to be in equilibrium as all the forces acting on the system cancel each other out.
In equilibrium
Total Anticlockwise Moment = Total
Total Anticlockwise Moment = TotalClockwise Moment
Scientists believe that a long time ago the seven continents might have been connected, but they think the plates shifted apart at some point.
the energy efficiency of a coal burning power plant is 33% and incandescent light bulb is only 10% and the electrical transmission lines between the power plant and the house is 70 %.
<h3>What is energy Efficiency?</h3>
The definition of energy efficiency is the use of less energy to carry out an activity or achieve a goal. Homes, buildings, and manufacturing facilities that use less energy to manufacture things require less energy to heat, cool, and operate appliances and gadgets.
One of the simplest and most economical methods to slow climate change, lower consumer energy bills, and boost the competitiveness of American businesses is via energy efficiency. In order to achieve net-zero emissions of carbon dioxide through decarbonization, energy efficiency is also a crucial factor.
