Answer:
I=0.0361 kg.m^2
Explanation:
Torque is the rotational equivalent of a force
Torque= perpendicular distance r X Force F
Torque T = I(moment of inertia) X α (angular acceleration)
T= Iα
r= 0.0285m
F= 1.9 x 10^3
T=0.0285 x 1.9 x 10^3
T= 54.15Nm
I=T/α
I=54.15/150
I=0.361 kg.m^2
Answer:
0.42 meters/second
Explanation:
The total distance traveled by Mary is: 80 m + 125 m + 45 m = 250 m
We want the speed in meters/second, so we have to convert the 10 minutes elapsed during the trip into seconds. Then we need a conversion factor, 1 minute is equivalent to 60 seconds.
time = 10 minutes * (60 seconds/1 minute) = 600 seconds (notice that minute is cancelled because is multiplying and dividing)
Now, we can compute the average speed is as follows:
Average speed = total distance/time = 250 m/600 s = 0.42 m/s
Tbh ! All of them have lens but I would go with B.) Smart Phone

Answer:
Explanation:
m = Mass of each rod
L = Length of rod = Radius of ring
= Mass of ring
