Answer:
7.5N
Explanation:
work=Force* distance
= 5*1.5
= 7.5N
Jolie is on the weightlifting team at her school, She uses a force of 5 N to lift 150 pounds of weight to a height of 1.5 m, so the work she will do is 5057.55 joules to lift the weight.

Hence, Jolie is on the weightlifting team at her school, She uses a force of 5 N to lift 150 pounds of weight to a height of 1.5 m, so the work she will do is 5057.55 joules to lift the weight.

B. The rating number means it will
protect you that many times
longer than without sunscreen
C. SPF ratings are only good in the
summer
D. SPF doesn't matter after 1 pm
Answer:
B. The rating number means it will protect you that many times longer than without sunscreen
Explanation:
The sun protection factor is a comparison between the length of time it will take for a skin that has no sunscreen to begin reddening compared to a skin with sunscreen applied. Therefore, the ratings is an indication of the length of time a person will be protected from ultraviolet rays than when the individual has no sunscreen applied.
While higher SPF's are believed to offer more protection against UV rays, the added protection is usually just a negligible amount. They are very important for the skin and protect the body against diseases like cancer.
