Displacement(d)=0.2m
Time taken(t)= 30 s(1min=60 s)
Velocity (v)=?
We know that,
Velocity (v) = d/t
=0.0067
Answer:
Solutions given:
Velocity ratio V.R =5
effort =500N
efficiency =80%
magnitude of load=?
mechanical advantage [M.A ]
we have
efficiency =M.A/V.R*100%
80=M.A./5*100
80/100*5=M.A
M.A.=4
again
we have
M.A =load/effort
4=load/500
load=500*4
load=2000N
<h3>
<u>the magnitude of the load is 2000N</u>.</h3>
Answer:
I think the answer is 0.2683281573
I think that the answer is b
Answer:
D) Ashley and Allan live about the same distance from the school
Step-by-step explanation:
1 m = 3.3 ft . . . . . . given
2000 m = 6600 ft . . . . . multiply the above equation by 2000
Since 6600 ft is about the same as 6000 ft, the appropriate choice is D.
