Answer:

a.95J

b.90J

Explanation:

a.Applying energy conservation laws:-

Energy Into Bulb= $Light \ Energy+Thermal \ Energy(Heat \ Energy)$

Given that light energy=5J,and Total Energy=100J

$Heat \ Energy= \Total \ Energy- Light \ Energy\\=100J-5J=95J$

b. Applying the laws in a above.

Total Energy=100J

Light Energy=10J

$Heat \ Energy=100J-10J=90J$

AveGali [126]

The thermal efficiency of an engine is
$\eta= \frac{W}{Q}$
where
W is the work done by the engine
Q is the heat absorbed by the engine to do the work

In this problem, the work done by the engine is W=200 J, while the heat exhausted is Q=600 J, so the efficiency of the machine is
$\eta= \frac{W}{Q}= \frac{200 J}{600 J}=0.33 = 33 \%$

Three resistors of 100 W, 3900 W, and 1000 W are connected in series across a 200-V battery. What is the voltage drop across the

Gala2k [10]

Answer:

40 V

Explanation:

I will assume that the resistors are

100 and 3900 and 1000 OHMS <=====(NOT W)

In series , the resistances add together 100 + 3900 + 1000 = 5000 ohms total

V = IR

I = V / R so the total current will be 200 v / 5000 ohms = .04 amps

this is the current through all of the resistors

so for the 1000 ohm resistor V = IR .04 (1000) = 40 V
