<u>Answer:
</u>
C option is correct
20 movable and 20 fixed pulleys required
<u>Explanation:
</u>
To lift a 27,800 N elephant with a 700 N drive,
27800/700=39.7
the individual requires a mechanical favorable position of 39.7 which is equivalent to 40. A solitary movable pulley gives a mechanical favorable position of 2, two portable pulleys yield a mechanical preferred standpoint of 4, and a framework with three movable pulleys results in a mechanical favorable position of 6. In light of this example, 20 movable pulleys and 20 fixed are required to give a mechanical preferred standpoint of 40
Answer:
The two answers are in the explanation
Explanation:
Please find the attached files for the solution
Explanation:
The given data is as follows.
M = 35 kg, radius (r) = 2.2 m,
m = 17 kg, = 11 rad/s
We assume that will be the final angular speed.
Now, according to the conservation of angular momentum.
or, 
Putting the given values into the above formula as follows.
or,
= 
= 7.58 rad/s
Thus, we can conclude that the angular speed of the clay and turntable is 7.58 rad/s.
Avg acceleration; under constant acceleration condition only; = Vf-Vi/time
a=Vf-Vi/time=(15m/s-6m/s)/(3s)=
(9m/s)/(3s)=3m/s^2
Hope this helps. Thanks.
Answer:
455,000 Pa
Explanation:
PV = nRT
If n is constant:
PV / T = PV / T
(101,325 Pa) (718 mL) / (273 K) = P (175 mL) / (26 + 273) K
P = 455,000 Pa
