Answers A and C can be automatically eliminated because evaporation has to do with the water cycle and magnetism has to do with electric current and such. Next we can eliminate B or distillation because it also has to do with water/liquids. Therefore, the answer is D or filtration because it is the only answer left.

I hope this helps!

A man pushes a stalled car with a force of 100 N. If the acceleration of the car is 0.75 m/s 2 , what is the mass of the car?
shutvik [7]
125 because f=ma so you would use 100=mx0.75

A pipe open at both ends has a fundamental frequency of 220 Hz when the temperature is 0°C. (a) What is the length of the pipe?
Allushta [10]

Explanation:

It is given that,

Fundamental frequency, f = 220 Hz

(a) We know that at 0 degrees, the speed of sound in air is 331 m/s.

For open pipe, \lambda=2l

l is the length of pipe

Also,

v=f\lambda

l=\dfrac{v}{2f}=\dfrac{331}{2\times 220}=0.75\ m

(b) Let f' is the fundamental frequency of the pipe at 30 degrees and v' is its speed.

v'=331\sqrt{1+\dfrac{T}{273}}

v'=331\sqrt{1+\dfrac{30}{273}}

v' = 348.71 m/s

So, f'=\dfrac{v'}{\lambda}

f'=\dfrac{348.71}{2\times 0.75}

f' = 232.4 Hz

Hence, this is the required solution.

A force of 7.50N is applied to a spring whose spring constant is 0.289 N/cm. Find its change in length.​
kotykmax [81]

Hook's law states that

F=k\Delta x

where F is the applied force, k is the spring constant, and \Delta x is the change in length.

Plugging your values, we have

7.5 = 0.289\Delta x \implies \Delta x = \dfrac{7.5}{0.289}\approx 25.95
