How much power is delivered to a light bulb on a 120V, 0.5A circuit?

jasenka [17]

Answer:

60 w

Explanation:

Given :

V= 120V

I=0.5 A

Now,

power can be calculated as :

P=VI

where,

V is voltage

I is current

Now,

P=(120)(0.5)

P=60 W

Therefore, 60w power is delivered to a light

What mass of silver will occupy a volume of 87.75 mL? The density of silver is 10.49 g/mL.

Anastaziya [24]

Answer:

The mass of silver that will occupy a volume of 87.75 mL is 920.5 grams.

Explanation:

Density is defined as the property that matter, whether solid, liquid or gas, has to compress into a given space. In other words, density is a quantity that allows us to measure the amount of mass in a certain volume of a substance. Then, the expression for the calculation of density is the quotient between the mass of a body and the volume it occupies:

$density=\frac{mass}{volume}$

So the density of silver is 10.49 g / mL indicates that 10.49 g occupies a volume of 1 mL. Then a rule of three can be applied in the following way: if in 1 mL a mass of 10.49 g is occupied, in 87.75 mL how much mass will it occupy?

$mass=\frac{87.75 mL*10.49 g}{1 mL}$

mass= 920.5 g

The mass of silver that will occupy a volume of 87.75 mL is 920.5 grams.

Is the sun yellow or is it orange.

LiRa [457]

Answer:

But the Sun isn't actually yellow; it's just an illusion caused by the Earth's atmosphere. The powerful processes happening inside the Sun are so robust that it emits every color of light imaginable. Together, these colors form a pure white light, which is precisely what you'd see from space.

The current through inductance L is given by I=I0e−t/τ

ohaa [14]

ΔVl = L di/dt
i = i₀e -t/T
di/dt = i₀ × (-1/T) e -t/T
ΔVl = L× (-I/T i₀e -t/T
ΔVl = -L/T i₀e -t/T

b. 15mm, i₀ = 36mA, T = 1.1m
t= Os
ΔVl = 0,491V
C. t = 1ms
ΔVl = 0.198V
t = 2ms
ΔVl = 0.08V

E. t = ms
ΔVl = 0.032V
