Answer:
0.56 km/s
Explanation:
We will define a single system of units for measurement, for this case meters per second [m/s]. That is, we must convert the rest of units such as centimeters per second and kilometers per second to meters per second.
![560[\frac{cm}{s}]*(\frac{1m}{100cm} )=5.6[m/s]\\0.56[\frac{km}{s}]*(\frac{1000m}{1km} )=560[m/s]](https://tex.z-dn.net/?f=560%5B%5Cfrac%7Bcm%7D%7Bs%7D%5D%2A%28%5Cfrac%7B1m%7D%7B100cm%7D%20%29%3D5.6%5Bm%2Fs%5D%5C%5C0.56%5B%5Cfrac%7Bkm%7D%7Bs%7D%5D%2A%28%5Cfrac%7B1000m%7D%7B1km%7D%20%29%3D560%5Bm%2Fs%5D)
Therefore the speed of 0.56 [km/s] is the greatest of all
Well since the bowling ball is at rest and is not moving at all, and assuming that the ball is on an even surface, the Fg is equal to the FN = normal force, and thus all forces are balanced, the Fnet = 0.
Answer:
Explanation:
Let's use the decay equation.
Where:
- A is the activity at t time
- A₀ is the initial activity
- λ is the decay constant
We know that 
So we have:
Therefore, the half-life of the source is 6 hours.
I hope it helps you!
