C. Rotations per second
Or normally we'd use Radians Per second
_Brainliest if helped!!
Answer:39.88 rad/s
Explanation:
Given
mass of cylinder m_1=18 kg
radius R=1.7 m
angular speed 
mass of 
dropped at r=0.3 m from center
let 
be the final angular velocity of cylinder
Conserving Angular momentum
Answer:
2.87m
Explanation:
Using the law of gravitation to solve this question
F = GMm/r²
G is the gravitational constant
M and m are the masses
r is the distance between the masses
Substitute the given values
G = 6.67×10^-11 m³/kgs²
M =8.8 x 10^6 kg
m = 5.6 x 10^5 kg
F =440N
400 = 6.67×10^-11×8.8 x 10^6 ×5.6 x 10^5/r²
400r² = 328.698×10
400r² = 3286.98
r² = 3286.98/400
r² = 8.21745
r = √8.21745
r = 2.87m
Hence the distance of separation is 2.87m
Answer: 20 newtons
Explanation:
Given that:
Force applied by Samantha = 10 newtons
Force applied by Emily = 10 newtons
Direction of both forces = same
Net force of their efforts = ?
Since net force of forces applied in the same direction is obtained by adding up the seperate forces applied, then
Net force = (10 newtons + 10 newtons)
Net force = 20 newtons
Thus, the net force of their efforts is 20 newtons.
Find the number of hours by dividing the distance by mph. The number of hours will be to the left of the decimal point:
250 miles / 65 mph
= 3.846153846
= 3 hours
2) Find the number of minutes by multiplying what is remaining from step 1 by 60 minutes. The minutes will be to the left of the decimal point:
0.846153846 x 60
= 50.76923076
= 50 minutes
3) Find the number of seconds by multiplying what is remaining from step 2 by 60 seconds. The seconds will be to the left of the decimal point:
0.76923076 x 60
= 46.1538456
= 46 seconds
So 3 hours 50 mins and 46 seconds
