Answer:
73.72
Explanation:
For this subtraction problem, the answer or solution is expressed to the least precise of the numbers we are trying to subtract.
The least precise number is the number with the lowest significant numbers:
105.4 - 31.681
105.4 has 4 significant numbers
31.681 has 5 significant numbers
So;
105.4
- 31.681
------------------
73.719
----------------
The solution is therefore 73.72
This is all related to the centripetal force. Rememeber that In uniform circular motion, velocity changes due to change in direction, eventhough magnitude remains constant. having that in mind we know that <span>She should change the direction of the vectors that are toward the center of the circle so that each points away from the center of the circle.</span>
<h3>Answer:</h3><h3>B.one coulomb</h3>
<h3>Explanation:</h3><h3>It takes an enormous number of electrons to equal one coulomb.In fact,it takes about 6.2x10¹⁸.Looking at this from the opposite perspective,one electron has a negative charge equal to -1.6x10¹⁹ coulombs.</h3>
Answer:
Explanation:
Because the electric potential can be written in 
, then we can find:
in N/C
The electric field is a constant electric field (the electric field is same for every distances from the charge) and the electric field is also comes from the negative point charge.
Earthquakes generate two types of waves p waves and s waves. p waves travel through solids liquids and gasses. s waves travel through only solids.
