Answer:
2.3 Nm clockwise
Explanation:
Take counterclockwise to be positive and clockwise to be negative.
∑τ = (3 N) (2.5 m) − (7 N) (1.4 m)
∑τ = 7.5 Nm − 9.8 Nm
∑τ = -2.3 Nm
The net torque is 2.3 Nm clockwise.
Answer:
A) After the Space Age ended, many people moved to other states and the economy began to decline.
Explanation:
After the space age ended, businesses slumped, when the space shuttle program ended those made redundant could not be re absorbed due to a lack of follow-on by NASA. The 2008 recession also had impacted businesses in the area. As such many moved to other states, which had the effect of a brain drain.
After Apollo, in the late 70's, there was a similar decline of economic activities as workers were laid off and where finding it hard to sell off their properties as the real estate prices where low.
Answer:
a = 2.5 m/s^2
Explanation:
u = 0
v = 25
t = 10
(using first eq. of motion)
a = (v - u) /t
a = (25 - 0) /10
a = 25/10
a = 2.5 m/s^2
Answer:
Time = 0.317 seconds.
Explanation:
Given the following data;
Distance = 1.65km to meters = 1.65 * 1000 = 1650 meters
We know that the speed of sound in steel is equal to 5200m/s
To find the time to hear the sound of the whistle;
Time = distance/speed
Substituting into the equation, we have
Time = 1650/5200
Time = 0.317 seconds.
Therefore, it will take him 0.317 seconds to hear the sound of the whistle.
