Answer:
the correct option is C
Explanation:
The intensity of a lamp depends on the power of the lamp that is provided by the current flowing over it, therefore the intensity would increase if we raise the current.
Another way to increase the intensity is to decrease the area with a focusing lens, as the intensity is power over area, decreasing the area increases the power.
When we see the possibilities we see that the correct option is C
Answer:
C) 100N
Explanation:
Formula for calculating the Weight of an object is expressed as;
Weight = mass × acceleration due to gravity
Given
Mass of the object = 10kg
Acceleration due to gravity = 9.81m/s²
Substitute into the formula above
Weight = 10×9.81
Weight = 98.1N
Hence the approximate weight of the object is 100N
