Thank you for posting your question here and Brainly!~
Even though you have not provided answer choices, I believe the answer is whatever letter corresponds with the answer: "It is rubbed with another object, and electrons move onto the rod."
Hope I helped!~ Brainliest appreciated.
Answer:
For the aceleration we have:
Vf = Vo + a * t
Clearing "a":
a = (Vf - Vo) / t
Replacing and resolving:
a = (34 m/s - 0 m/s) / 21 s
a = 34 m/s / 21 s
a = 1,61 m/s^2
The aceleration of the vehicle is<u> 1,61 meters per second squared</u>
Time = distance/speed
Time = (175 m) / (320 m/s)
<em>Time = 0.547 second</em>
Answer:
Magnitude F(t)=26.6 N
Direction: -x
Explanation:
Given data
Spring constant K=4.77 N/m
Mass m=1.89 kg
Displace A=5.56m
Time t=3.96s
To find
Magnitude of force F
Solution
The angular frequency is given as

Force on object is

Substitute given values
So

So
Magnitude F(t)=26.6 N
Direction: -x
