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:
It's the natural tendency of things to keep going unless there's something trying to stop them.
It's usually called "inertia".
Don't get the idea from all of this that things stop unless there's something to keep them going. The truth is exactly the opposite: Things keep going unless there's something to make them stop.
<span>The collision produces forces between the car and the bug. These forces depend on the momentums of the objects that collide.
Momentum is the product of mass and velocity. The greater the mass the smaller the acceleration. That is the Newton's second law. Because the mass of the car is greater, it's momentum is also greater and the accelaration is smaller. so, the bigger momentum of the car explains the different damage.</span>

Hello
The period of a wave is the time it takes between two complete oscillations of the wave itself, i.e. it is the time that occurs between two consecutive wavelengths. Therefore, if we want to calculate how many wavelengths pass a certain point in
![t=2~min=120~s](https://tex.z-dn.net/?f=t%3D2~min%3D120~s)
, we need to divide the total time for the period of the wave, T:
![N= \frac{t}{T}= \frac{120~s}{15~s}=8](https://tex.z-dn.net/?f=N%3D%20%5Cfrac%7Bt%7D%7BT%7D%3D%20%5Cfrac%7B120~s%7D%7B15~s%7D%3D8%20%20)
So, the answer is 8 wavelengths.
