The width of the rectangle is 15in
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>
A = 15 3 x 15 + 9 = 54 keep up the good work!
Answer:
1:none
2:c
3:b
4:a
Step-by-step explanation:
Answer:
- D. 5.7 km/h north and 5.8 km/h west are instantaneous velocities, while 8.1 km/h northwest is the average velocity.
Step-by-step explanation:
We are given directions and position change.
This is about the velocity, the speed doesn't take into account the direction.
We also see the change in the velocity. The numbers give us instantaneous velocities and the displacement is the average velocity as the sum of vectors.
Considering the above explanation, correct choice is D.
