Answer:
Spring constant, K = 415.9 N/m
Explanation:
The period of vibration of a spring, T, is given by:
T = 2√m/K
Where m = mass of the body in kg, K = spring constant or force constant or elastic constant or stiffness in Nm-1
Making K the subject of the expression,
K = m(2)2/(T)2
K = 4m()2/(T)2
Where m = 0.38kg, = 3.14285714286, T = 0.19s
K = 4 x 0.38 (3.14285714286)2 / (0.19)2
K = 4 x 0.38 x 9.87755102043 / 0.0361
K = 15.0138775511 / 0.0361
K = 415.9 Nm-1
Equality is giving everyone the same amount of something. Equity is giving those who are in need more of something in order to help them be equal with others. For example, an equalist will give everyone the same amount of food regardless of their size. An equitist, on the other hand, will give food in accordance to one's size. In my opinion, both have their pros and cons.

Answer:
Predictive validity.
Explanation:
A Predictive validity test is the test that is taken to predict the future performance of the applicant based on the scores in the test. The test is useful in predicting the future, as suggested by the name.
The tests that are taken before allowing a person in any organisation are often predictive. A pre-employment test is such example.
<u>In the given case, the entrance exams are also an example of predictive validity. It is because based on the scores scored by a student will help the university authorities about the performance of the student</u>.
So, the correct answer is predictive validity.
