Answer:
Assuming the charged density in the insulated solid sphere of radius 3.1m is 8.8e-9, the electric field at 5.2 meters is 73.1256 .
Explanation:
The electric charge linear density is equal to 8.8 x
the radius of the sphere is 3.1m
The magnitude of the electric field at the radius of the sphere equal to 5.2 meters can be calculated with the formula ;
- E = λ / 4πε₀ [ r / α ( α + r ) ]
Solution:
E = 8.8 x / 4πε₀ [ 3.1/ 5.2( 5.2 + 3.1) ]
= 1018.0995 [0.07183]
= 73.1256
Answer:
340 meters
Explanation:
For this we have to use the formula of constant velocity motion:
Because you hear the blows exactly 1 per second. And you hear only one blow after she finished, the sound takes one second to get to you.
Answer:
The greater the luminosity of a star, the longer its period of oscillation.
Answer:
<u> George Washington</u>
<u>Explanation:</u>
The image of the famous first President of the United States-George Washington (from 1789 to 1797) is found on every $1 bill. George Washington's image began to be found on the $1 bill in 1869.
Answer:
D. Electricity will flow if the electrons are bound loosely to their atoms in the material.
Explanation:
The continuous flow of charges is known as electricity (current). The flow of these charges are due to free or mobile electron within the atoms of the conductors. The materials which will allow current to pass through them, must have free or mobile electrons which are loosely bound to their atoms.
Thus, the correction for this question is "D"
D. Electricity will flow if the electrons are bound loosely to their atoms in the material.
