Answer:
50 kg·m/s.
Explanation:
Momentum can be calculated using p = mv. (Let p represent momentum, m represent mass, and v represent velocity.)
Plugging our terms in, we have p = 5 kg * 10 m/s. This gives us p = 50 kg·m/s as an answer.
To solve this problem it is necessary to apply the concepts related to Wavelength depending on the frequency and speed of light.
The equation that meets these parameters is given by
Where,
c = Speed of light
f = Frequency
Our values are given as
velocity of light in free space
f = 2Hz
Replacing we have that
Therefore the correct answer is B.
The correct answer is mass
Answer:
The correct answer is - 43%.
Explanation: The increase in CO2 between these two suggested periods is approximately 43%. Even though it is a natural process that the CO2 levels vary in the atmosphere, still this is not the same case nowadays. Nowadays, or rather in the past few decades, apart from the natural increase of CO2 in the atmosphere, it has seen a much more increased levels because of the human activity. The industrial facilities and the vehicles, the cutting of the forests and burning the wood (there's both release of CO2 from the burning of the trees and loss of natural accumulator of the CO2), are just some of the more important human activities that contribute to a significant rise in the CO2 levels.
Answer:
the y axis, every moment is subjected to a vertical acceleration directed towards the center of the Earth, which is called the acceleration of gravity
Explanation:
In projectile launching, the movement is separated into two movements, one on the x-axis and the other on the y-axis, related through time.
In horizontal movement, the speed is constant, because there is no acceleration in this axis, the effect of air friction is almost always eliminated.
In the other movement on the y axis, every moment is subjected to a vertical acceleration directed towards the center of the Earth, which is called the acceleration of gravity.
This value of the eceleration of gravity is constant for small distances
compared to the radius of the Earth, for higher altitudes an expansion in beings of the distance is used, giving a linear dependence.
