The effort distance will be 160 cm.Applying the moment at the center as follows will provide the effort distance:
<h3 /><h3>What is the mechanical advantage?</h3>
Mechanical advantage is a measure of the ratio of output force to input force in a system, it is used to obtain the efficiency of forces in levers and pulleys.
Given data;
Effort,
Load,
Distance from the fulcrum,
The effort distance is found by applying the moment at the center as;
Hence, the effort distance will be 160 cm

Answer:
<em>300 W</em>
<em></em>
Explanation:
power of each bulb P = 75 W
voltage in the circuit = 120 V
we know that electrical power P = IV ....1
and V = IR
we can also say that I = V/R
substituting for I in equation 1, we have
P = 
....2
The total total power in the circuit = 75 x 2 = 150 W
from equation 2, we have
150 = 
R = 
= 96 Ω this is the resistance of the whole circuit.
This resistance is due to the two light bulbs, for each light bulb since they are arranged in series
R = 96/2 = 48 Ω
From P =
for each light bulb, power is
P = 
= <em>300 W</em>
Answer:
If the speed is 70 mile/hour, the time to drive the 256 miles is:
T = 256/70 = 3.66 hours = 3 hours and 39.6 minutes
If you leave at 3:00, then at 6 hours and 39.6 minutes, you will get there.
Hope this helps!

Answer:
60 N
Explanation:
This is just Newton's Second Law
F = m*a
F = ?
m = 12 kg
a = 5 m/^2
F = 5*12 = 60 Newtons
