Answer:
2.73 K
Explanation:
The Cosmic Microwave Background (CMB) radiation are a type of electromagnetic radiations that are released after the explosion of the big bang. It propagates in all direction in space and is moving further with the expansion of the universe. They are not visible but they are helpful in estimating the age of the universe.
These radiations have a wavelength of about 970 μm (approximately 1 mm).
The temperature of the corresponding blackbody of this radiation is approximately <u>2.73 K(-270.42°C)</u> and its extremely cold.
Answer:
Explanation:
The rest energy is the energy associated with the base ball at zero velocity which is expressed as
Note: the speed C is the speed of light which is expressed as 3*10^8
while the kinetic energy is the energy associated with the ball during its motion and is expressed as
the ratio can be expressed as
I don't know why the answer is D , because I can't see the list of choices.
The only way to get 8.0 Amps is by making a serious mistake.
The current in the second picture is 4.0 Amps.
If the resistors are identical, then the effective resistance of
two resistors in parallel is 1/2 the resistance of each one.
The resistance in the second picture is 1/2 the resistance
in the first picture.
Current = (voltage) / (resistance)
Cutting the resistance in half causes the current to double.
If the current was 2.0 Amps in the first picture, it's 4.0 Amps
in the second picture.
It would have to be the right type of metal like copper to run through it
Answer:
a
The speed is 
b
The distance is 
Explanation:
From the question we are told that
The speed of the banana is 
The distance from my location is 
The time taken is 
The speed of the ice cream is
substituting values
The distance of separation between i and Valdimir is the same as the distance covered by the banana
So
substituting values
