A lamp is plugged into a standard 120-volt outlet. If the lamp draws a current of 0.5-amps, how much energy is consumed in 1 minute?

Answers

Answer 1

Answer: One handy formula for electrical power ... the one that's
most helpful here ... is:

Power = (voltage) x (current).

so Power = (120 volts) x (0.5 ampere) = 60 watts.

Now 60 watts means 60 joules of energy per second.
In one minute, the lamp dissipates

(60 joules/second) x (60 seconds/minute) = 3600 joules/minute.

Which of these is NOT an event that helped make the Moon as it is today?a. Iron sank into Earth's core.
b. Plate tectonics caused lava to flow.
c. Earth and a planetesimal collided.
d. The lunar surface melted and was bombarded by meteoroids

Answers

The correct answer to the question that is stated above is letter b, Plate tectonics caused lava to flow. All of the options are mentioned in the theories of the formation of the moon except for letter B.

There are 5 serious theories about the formation of the moon,these are:
The Fission Theory--
The Capture Theory--
The Condensation Theory--
The Colliding Planetesimals Theory--
The Ejected Ring Theory--

See attached file for the description of each theory.

A 70 kilogram mountaineer is standing on the summit of Mt. Everest. The distance between the mountaineer and the center of Earth is 6.39 × 106 meters. What is the magnitude of the force of gravity acting on the mountaineer? (The value of G is 6.673 × 10-11 newton meter2/kilogram2. The mass of Earth is 5.98 × 1024 kilograms.)90.50 newtons

111.5 newtons

684.1 newtons

4041.7 newtons

Answers

The force due to gravity between two point masses is given by:
F = GMm/r²; where G is the gravitational constant, M is the larger mass, m is the smaller mass, and r is the distance between the two.
F = (6.673 × 10⁻¹¹ × 5.98 × 10²⁴ × 70) / (6.39 × 10⁶)²
F = 684.1 N

F = GMm/r²

F = (6.673*10^-11)(5.98*10^24)(70)/(6.39*10^...

F = 684 N (3sf)

At its closest point, Mercury is approximately 46 million kilometers from the sun. What is this distance in AU?

Answers

This problem can be solved using the following relation: 1 kilometer = 6.6846e-9 AU. Since we are already given the number of kilometers, we simply have to multiply it to its equivalent in AU to solve for the equivalent distance. This is done below:

46 000 000 * 6.6846e-9 = 0.3 AU

A wave travels at a constant speed. How does the frequency change if the wavelength increases by a factor of 2?A.The frequency decreases by a factor of 2. B.The frequency increases by a factor of 4. C.The frequency increases by a factor of 2. D.The frequency does not change.

Answers

Answer : The frequency decreases by a factor of 2.

Explanation :

Given that the wave travels at a constant speed. The speed of the wave is given as :

$v=\nu* \lambda$

Where

υ is the frequency of the wave

and λ is the wavelength of the wave.

In this case, the speed is constant. So, the relation between the frequency and the wavelength is inverse.

$\nu\propto (1)/(\lambda)$

If the wavelength increases by a factor of 2, its frequency will decrease by a factor of 2.

Hence, the correct option is (A) " The frequency decreases by a factor of 2 ".

A.The Frequency decreases by a factor of 2.
