Answer:
Horizontal Motion, and Vertical Motion.
Explanation:
Answer:
velocity in problems per hour = 4 per hour
so correct option is b. 4 per hour
Explanation:
given data
worked on homework time = 1.5 hour
completed = 6 problems
to find out
What is the velocity in problems per hour
solution
we know that Shirley solve complete 6 accounting homework problem in 1.5 hour so her velocity in problems per hour will be as
velocity in problems per hour =
..................1
put here value we will get
velocity in problems per hour = ![\frac{6}{1.5}](https://tex.z-dn.net/?f=%5Cfrac%7B6%7D%7B1.5%7D)
velocity in problems per hour = 4 per hour
so correct option is b. 4 per hour
I think the answer is
a.touching chemical solvent
Dermatitis is a general term that describes an inflammation of the skin. Dermatitis can have many causes and occurs in many forms. It usually involves an itchy rash on swollen, reddened skin.
Skin affected by dermatitis may blister, ooze, develop a crust or flake off. Examples of dermatitis include atopic dermatitis (eczema), dandruff and rashes caused by contact with any of a number of substances, such as poison ivy, soaps and jewelry with nickel in it.
Answer:
![T=2.5*10^{-3}s](https://tex.z-dn.net/?f=T%3D2.5%2A10%5E%7B-3%7Ds)
Explanation:
From the question we are told that:
Beat frequency ![F_b=4](https://tex.z-dn.net/?f=F_b%3D4)
Frequency ![F=400Hz](https://tex.z-dn.net/?f=F%3D400Hz)
Generally the equation for Frequency of the violin is mathematically given by
![f_v=F_b+F](https://tex.z-dn.net/?f=f_v%3DF_b%2BF)
![f_v=4+400Hz](https://tex.z-dn.net/?f=f_v%3D4%2B400Hz)
![f_v=404Hz](https://tex.z-dn.net/?f=f_v%3D404Hz)
Therefore the period of the violin string oscillations is
![T=\frac{1}{f_v}](https://tex.z-dn.net/?f=T%3D%5Cfrac%7B1%7D%7Bf_v%7D)
![T=\frac{1}{404}](https://tex.z-dn.net/?f=T%3D%5Cfrac%7B1%7D%7B404%7D)
![T=2.5*10^{-3}s](https://tex.z-dn.net/?f=T%3D2.5%2A10%5E%7B-3%7Ds)

I think it's A, I'm not sure though
