<u><em>Answer:</em></u>498.82 cg is equivalent to 4988.2 mg
<u><em>Explanation:</em></u>cg stands form centigrams
mg stands for milligrams
From the standards of conversion, to convert from centi to milli, we multiply the amount ny 10
<u>This means that:</u>
1 centigram = 10 milligram
To convert 498.82 cg to mg, all we have to do is <u>cross multiplication</u> as follows:
1 cg ..................> 10 mg
498.82 cg .........> ?? mg
498.82 cg = </span>

<span> = 4988.2 mg
Hope this helps :)</span>
Answer:
Bulb 1 has more resistance.
Explanation:
Given that,
Two lightbulbs work on a 120-V circuit.
The power of circuit 1, P₁ = 50 W
The power of circuit 2, P₂ = 100 W
We need to find the bulb that has a higher resistance.
The power of the bulb is given by :

For bulb 1,

For bulb 2,

So, bulb 1 has higher resistance.
Answer:

Explanation:
The torque applied by a force can be calculated as

where
F is the magnitude of the force
d is the length of the arm
is the angle between the direction of the force and the arm
In this problem, we have
F = 15 N
d = 2.0 m

Substituting into the equation, we find
