Answer:
option b is correct.
Explanation:
Since the position as a function of time is given by
which is a periodic function thus the motion of the particle repeats after a time of 2 seconds thus among the given options only option b is case of repetitive motion thus option b is most appropriate since the spinning wheel repeates it's motion.
The above given sentence is true reason being the use of Technology.
Explanation:
The basic purpose double technology is to make hard work easier and help in meeting the needs. Technology was being developed and is being upgraded so as to make some of the tasks, which were harder to do without it, easier.
Development of Technology has made the work easier and the needs are being met with an additional profit of saving time.
It would have to be the right type of metal like copper to run through it
Answer:
k=320N/m
Explanation:
Step one:
given data
Let the initial/equilibrum position be x
mass m1= 0.2kg
F1= 0.2*10= 2N
elongation e= 9.5cm= 0.095m
mass m2=1kg
F2=1*10= 10N
elongation e= 12cm= 0.12m
Step two:
From Hooke's law, which states that provided the elastic limits of a material is not exceeded the extention e is proportional to applied Force F
F=ke
2=k(0.095-a)
2=0.095k-ka----------1
10=k(0.12-a)
10=0.12k-ka----------2
solving equation 1 and 2 simultaneously
10=0.12k-ka----------2
- 2=0.095k-ka----------1
8=0.025k-0
divide both side by 0.025
k=8/0.025
k=320N/m
