Gases expand to fill all the space available. Their particles fly all over the place, and they take the shape and volume of whatever you put them in.
Answer:
41.8° to the vertical ( west of North) , 44.6 s
Explanation:
Using Pythagoras theorem, taking the direction it must go line as the hypotenuse
vh² = vs² + vd² vs is the speed of the stream, vh is the speed in the direction it must go to the vertical and vd is the speed going directly north
3 ² = 2² + vd²
9 - 4 = vd²
√5 = vd
2.24 m/s = vd which is the resultant speed
the direction it will go = tan θ = 2 / 2.24
θ = tan⁻¹(2 / 2.24) = 41.8° to the vertical ( west of North)
b)t = distance / v = 100 / 2.24 = 44.6 s
Answer:
An image of the cosmic microwave background radiation, taken by the European Space Agency (ESA)'s Planck satellite in 2013, shows the small variations across the sky (Image credit: ESA/Planck Collaboration) The cosmic microwave background (CMB) is thought to be leftover radiation from the Big Bang, or the time when the universe began
Explanation:
The formula to find the speed of a wave
speed = wavelength x frequency
speed and frequency are directly proportional so as one increases then the other one will increase as well. in this case as the frequency increases then the speed of the wave will also increase.
hope this helps :)
