A cord can withstand 3,000 N of tension before it snaps. If a moving company uses this chord to hoist a 200 kg piano with an acceleration of 5.00 m/s2, will the
cord snap? *
a. No, the cord will not snap because there is 1,000N of force from the piano
b. Yes, the cord will snap because there is 5,000N of force from the piano
c. Yes, the cord will snap because there is 10,000N of force from the piano
d. No, the cord will not snap because there is 500N of force from the piano

In a vernier instrument the main scale is in 1/2 mm divisions .vernier is made by redividing 19 such divisions into 20 equal parts. calculate the least count of the instrument.

Explain the difference between each pair of concepts. a. frequency and relative frequency b. percentage and relative frequency a. select the correct choice below. a. frequency is the total number of observations in a data set. relative frequency is the number of times a particular distinct value occurs. b. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of a value to the total number of observations. c. frequency is the total number of observations in a data set. relative frequency is the ratio of the number of times a particular distinct value occurs to the frequency. d. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of two different values.
