The color of light that a star emits is somewhat related to its age, whereas the color of light that we actually <em>observe</em> from a star is related to the speed at which it's moving with respect to us.
Answer:
No
Explanation:
The fastest recorded time for a person to run 100 metres is 9.58 seconds, which is the equivalent of 10.4 metres per second
The forces acting on your mom while cooking is Air resistance and the force of friction
<u>Explanation:</u>
<u>1. Air resistance:</u>
- In simple words, Air resistance can be stated as the type of friction between the air and the other materials.
- In this scenario, there will be an air resistance and the air hits the mom while cooking via the doors or windows
<u>2. The force of friction:</u>
- In simple words, friction can be stated as, the resistance that one surface or object encounters when moving over another.
- While cooking the food mom would experience the friction since friction is the transfer of heat, and cooking is the process of receiving that heat.
Answer:
a) p = 4.96 10⁻¹⁹ kg m / s
, b) p = 35 .18 10⁻¹⁹ kg m / s
,
c) p_correst / p_approximate = 7.09
Explanation:
a) The moment is defined in classical mechanics as
p = m v
Let's calculate its value
p = 1.67 10⁻²⁷ 0.99 3. 10⁸
p = 4.96 10⁻¹⁹ kg m / s
b) in special relativity the moment is defined as
p = m v / √(1 –v² / c²)
Let's calculate
p = 1.67 10⁻²⁷ 0.99 10⁸/ √(1- 0.99²)
p = 4.96 10⁻¹⁹ / 0.141
p = 35 .18 10⁻¹⁹ kg m / s
c) the relationship between the two values is
p_correst / p_approximate = 35.18 / 4.96
p_correst / p_approximate = 7.09
