Answer:
electrical 'pressure' measurement
Explanation:
The polaris is a star which appear to stand still while the rest of the stars move due to the rotation of the earth.If u are standing at the north pole the polaris would be directly above you.To find the polaris u must first find the big dipper which is like a bowl with handle and the move like 5 time to find the polaris
Answers:
a) 222.22 m/s
b) 800.00 km/h
Explanation:
The speed of a wave is given by the following equation:
Where:
is the speed
is the frequency, which has an inverse relation with the period ![T=1 h](https://tex.z-dn.net/?f=T%3D1%20h)
is the wavelength
Solving with the given units:
This is the speed of the wave in km/h
Transforming this speed to m/s:
![v=800.00 \frac{km}{h} \frac{1 h}{3600 s} \frac{1000 m}{1 km}](https://tex.z-dn.net/?f=v%3D800.00%20%5Cfrac%7Bkm%7D%7Bh%7D%20%5Cfrac%7B1%20h%7D%7B3600%20s%7D%20%5Cfrac%7B1000%20m%7D%7B1%20km%7D)
This is the speed of the wave in m/s
The answer would be a speed
Answer:
Number of absent affects the grade
Explanation:
the dependent variable is the grade and the independent variable is the number of absent, since the grade depends of the number of absents.
