Answer:
666 bc its on its way to my house
Explanation:
Answer:
<h2>3</h2>
Explanation:
Using the efficiency formula. Efficiency = MA/VR * 100%
MA = Mechanical Advantage
VR = velocity ratio = 
Distance moved by effort = 4.5m
distance moved by load = 1.5m
VR = 4.5/1.5 =3
Assuming efficiency is 100% (since friction can be ignored)
100% = MA/3 * 100%
1 = MA/3
MA = 3*1
MA = 3
Mechanical Advantage of the ramp is 3
Answer:
4 d
Explanation:
because the spring is balanced with t
Answer:
(a) T=6.07s
(b) 
Explanation:
For Part (a)
The initial amplitude is given as A=7.0 cm
Apply the equation
with
we have:

For Part (b)
Apply
with t=4.0s and T=6.07s we have
