Answer:
-78.4 cm
Explanation:
We can solve the problem by using the lens equation:
where
p is the distance of the object from the lens
q is the distance of the image from the lens
f is the focal length
Here we have
p = 80.0 cm
q = -39.6 cm (negative, because the image is on the same side as the object , so it is a virtual image)
Substituting, we find f:

(1.4 x 10⁵ newton/coulomb) x (-1.6 x 10⁻¹⁹ coulomb)
= (1.4 x 10⁵ x -1.6 x 10⁻¹⁹) newton-coulomb/coulomb
= - (1.4 x 1.6) x 10⁵⁻¹⁹ newton
= - 2.24 x 10⁻¹⁴ newton
Answer:
165 degrees F (high)
Explanation:
to destroy the most heat pathogens found in raw poultry
A) It is very dry at the equator because it is so hot.
False. It depends on what else is around.
The Sahara Desert is near the Equator.
But so is the Amazon rain forest.
B) Higher places are usually warmer because they are closer to the Sun.
False. Higher places are usually colder, because the air is thinner.
C) Land masses change the direction of currents.
True
D)The sun provides energy needed for the evaporation process. Gravity allows water droplets to fall as precipitation.
True
Answer:C
Explanation:
Power=280watts=280/1000 kilowatts
Power=0.28 kilowatts
Device use 0.28 kilowatts in 1 day
1day=24hours
Device use 0.28 kilowatts in 24hours
30days=30 x 24=720 hours
For 720 hours=(0.28x720) ➗ 24
For 720 hours=201.6 ➗ 24
For 720 hours=8.4
