Hi

I need a help to solve these 3 questions in my physics class asap. I wrote down here q number 2 and I upload 2 more questions because they has pictures

When a 0.750-kg mass oscillates on an ideal spring, the frequency is 1.35 Hz .

Part A

What will the frequency be if0.190kg are added to the original mass? Try to solve this problem without finding the force constant of the spring.

Express your answer with the appropriate units.

Part B

What will the frequency be if0.190kg are subtracted from the original mass? Try to solve this problem without finding the force constant of the spring.

EXPRESS YOUR ANSWER WITH THE APPROPRIATE UNITS.

Part 4 for q number 3 I can not add any file I will write it down here

What is the mass m?
