Answer:
Explanation:
First of all, we calculate the resistance of the lamp. The power of the lamp is given by
Where
P = 100 W is the power
V = 250 V is the voltage
R' is the resistance of the lamp
Solving for R',
Now this resistance is connected in parallel to the other resistance R, so their equivalent resistance is
(1)
Now the total power in the circuit is
P = 1100 W
And the voltage is
V = 250 V
So we can write
to find the equivalent resistance:
Therefore, rearranging (1), we find R:
Answer:Density is the mass of an object divided by its volume. Density often has units of grams per cubic centimeter (g/cm3). ... You probably have an intuitive feeling for density in the materials you use often. For example, sponges are low in density; they have a low mass per unit volume.
Explanation:
Answer:
increases
Explanation:
when the mass of an object is constant and you add more force, acceleration increases
