All electromagnetic waves travel at 3*10^8 ms⁻¹ , the equation for wave speed is v=wavelength*frequency. Therefore wavelength=v/f=3*10^8/600000000=0.5m
Answer:
A
Explanation:
F=ma
2F=2ma
If m stays constant, then the acceleration must double, or increase by a factor of 2. Therefore, the correct answer is choice A. Hope this helps!
Crystalline metals are solids that are made up of crystals.
Answer:ITS B
Explanation: TOOK DA TEST AND GOT IT RIGHT NO CAP YOUR WELCOME
We will have the following:
First, the equation to use is the following:

Now, we transform the total distance the cat would need to travel:

So, the cat would need to travel 1.5 meters. ("d" in the equation).
Now, using the speed given we determine the time it would take the cat to traverse the 1.5 meters:

So, the time it would take the cat to traverse the distance will be approximately 3.33 seconds.
Now, we know that the acceleration will be given by Earth's gravity, so:


So, the initial vvelocity the cat must leave the floor in order to arrive at the butterfly with the optimum pouncing speed of 0.45 m/s is approximately 16.78 m/s or exactly 1007/60 m/s.
