Answer:
The fundamental units are the base units defined by International System of Units. These units are not derived from any other unit, therefore they are called fundamental units. The seven base units are: Meter (m) for Length. Second (s) for Time.
Explanation:
Knowing the force and distance allows you to calculate the work done.
Then, if you know the TIME, you can calculate the power.
<h2>Answer:</h2>
<u>The number of neutrons is </u><u>47</u>
<h2>Explanation:</h2>
In order to find the number of neutrons we subtract the atomic number from the atomic mass.
In the given case the atomic number is 23 and mass number is 70 so
No of neutrons is 70 -23 = 47
You have to be 90 m away from the cat
Just divide 90 by 17.4 and you will get - 5.172 seconds
- It will take 5.17 seconds to accelerate uniformly to stop in exactly 2 m before the cat
