What is the power of 4ohm resistor connected to a 12v battery?
NemiM [27]

Answer:

36watts

Explanation:

Data obtained from the question include:

R (Resistor) = 4 Ohms

V (Voltage) = 12V

P (power) =?

P = IV

Recall: I = V/R

P = V^2 /R

P = (12)^2 /4

P = 144/4

P = 36watts

Therefore, power is 36watts

Zielflug [23.3K]
<span>While modern humans first evolved approximately 200,000 years ago,
the age of the Earth, the Sun, and the rest of the solar system is believed
to be approximately 4.6 billion years.

That makes the Earth, the Sun, and the rest of the solar system
something like  23 thousand times  as old as the human species !

A star is a ___ that emits energy produced by nuclear reactions in its interior.
grigory [225]

A star is a large ball of gas that emits energy produced by nuclear reactions in the star's interior. Much of this energy is emitted as electromagnetic radiation, including visible light. Light emitted by stars enables other objects in the universe to be seen by reflection.

What is a wave? Use the terms wavelength and frequency in your definition.
adelina 88 [10]

Explanation:

A wave is a disturbance in a medium. For example, when some pebbles are thrown in water, the water particles gets disturbed. A wave is characterized by the following parameters i.e.

Frequency

Wavelength etc

The number of oscillations or vibrations in a medium is called the frequency of a wave.

Also, the distance between two consecutive crests and troughs is called the wavelength of a wave. The relationship between the wavelength and the frequency of a wave is given by :

Speed of wave = frequency × wavelength

When a falling meteoroid is at a distance above the Earth's surface of 3.40 times the Earth's radius, what is its acceleration d
Alchen [17]

Answer:

g = 0.85 ms^{-2}

Explanation:

g = \frac{GM}{h^{2} }

were; g is the acceleration due to Earth's gravity, G is Newton's gravitation constant (6.674 x 10^{-11} Nm^{2}kg^{-2}), M is the mass of the earth (5.972 x 10^{24} kg), and h is the distance of meteoroid to the earth.

h = 3.40 x R

  = 3.40 x 6371 km

h = 21661.4 km

  = 21661400 m

Thus,

g = \frac{6.674*10^{-11}*5.972*10^{24}  }{(21661400)^{2} }

  = \frac{3.9857 *10^{14} }{4.6922*10^{14} }

  = 0.84944

g = 0.85 ms^{-2}

The acceleration due to the Earth's gravitation is 0.85 ms^{-2}.
