Answer:28 m
Explanation:
Given
Direction is 
North of east i.e. 
with x axis
Also ball moved by 33 m
therefore its east component is 33cos58=17.48 m
Northward component 
None can.

Answer: 2 seconds is the unit rate.
Explanation:
We know that Jason does 30 pushups in 60 seconds at a constant rate, and we know that each push up takes 2 seconds.
then, we can write this as 30 pushups/60 seconds = (1/2) pushups per second.
Here, two seconds represents the time needed to do one pushup, is the unit rate (this means that we need 2 seconds to have a unit "one pushup")
Wave 3 will move the slowest, the statement could made about the data collected in Hamish's table
Answer: Option C
<u>Explanation:
</u>
Sound waves require medium to pass from one to another. Depending upon the density of molecules in the medium, the speed of the sound waves can be determined. As we know that compression and rarefactions will be formed for propagation of sound waves when the waves collide with molecules of the medium.
So, if there is less molecules present in the medium or loosely packed molecules present in the medium with high mean free path length than the sound wave will be travelling slowly in that medium.
Thus, as we known that gas has the loosely packed molecules among the other states of matter, so wave 3 which is made to pass through the gas medium will be propagation at the lowest speed or will move the slowest compared to other 3 gases made to propagate in solid and liquid mediums.
