a)
Answer: 0.91 m
Explanation:
We know that,
P.E. = m g h
Where,
P.E = Potential energy
m = Mass of the object
g = acceleration due to gravity (9.8 m/s²)
It is given that, m = 1.5 kg
P.E. = 13.44 J
⇒ 13.44 = 1.5 kg × 9.8 m/s² × h
⇒ h = 0.91 m
Hence, apple sits om 0.91 m tall counter.
b)
Answer: 216 J
Explanation:
P.E. = m g h
Weight, mg = 120 N ( given)
height, h = 1.8 m ( given)
The energy possessed by the suitcase is due to virtue of its position (gravitational potential energy)
P.E. = 120 N × 1.8 m = 216 J
Hence, the energy possessed by the suitcase sitting on the counter is 216 J.
The answer will be 17 tons.
Step-by-step explanation:
Since we have given that
14 T 1,000 lb. + 2 T 1,000 lb.
As we know that

So, 14 T 1,000 lb. is given by

Similarly,

so,
2T 1,000 lb. is given by

So, 14 T 1,000 lb. + 2 T 1,000 lbs is given by

Hence, the answer will be 17 tons.

<h2>
Answer with explanation:</h2>
A. For males, Third quartile =14, First quartile = 3 (approx)
IQR = Third quartile - First quartile
= 14-3 = 11
B. For males, Median = 12
For females, Median = 17
The difference between the median values = 17-12=5
C. The mean would be a better measure of center for females because the data has no outliers.
The median would be a better measure of center for males because the data has outliers.
D. Reason for outlier: A large number of males gone for movie which is extreme value for the remaining values.
