<h2>Answer:</h2>
<u>The intensity is </u><u>49 Candelabra</u>
<h2>Explanation:</h2>
The formula for calculation the luminous intensity is;
Luminous intensity = illuminance × square radius
Lv = Ev × r²
= 3.5 × 2²
= 3.5 × 14
= 49 Candelabra
There are no nonmetals on the list you provided.
Answer:
The radius r of the metal sphere
Explanation:
Electric field, where Q is the magnitude of the charge, R is the distance from the center of the metal sphere. Whenever the sign of the charge changes, the direction of electric field also changes. Therefore, it's only the the radius r of the metal sphere does not affect the electric field at a distance R from the center of the metal sphere when R>r
<span>B). it will decrease.
But, you should keep the temperature constant, 'cause according to Boyle's law, pressure of the ideal gases is indirectly proportional to it's volume but at constant temperature. So, don't confuse in that.
Hope this helps!
