Answer:
I would say a pond
Explanation:
A pond is more still than an ocean, therefore you could see your reflection better
An object with a velocity (v) of 9 m/s and a linear momentum (p) of 72 kg.m/s, has a mass (m) of 8 kg.
<h3>What is momentum?</h3>
In Newtonian mechanics, linear momentum, or simply momentum, is the product of the mass and velocity of an object.
It is a vector quantity, possessing a magnitude and a direction.
The mathematical expression for momentum is:
p = m . v
where,
- p is the linear momentum of the object.
- m is the mass of the object.
- v is the velocity of the object.
An object has a velocity (v) of 9 m/s and its linear momentum (p) is 72 kg.m/s. We will use the definition of linear momentum to calculate the mass of the object.
p = m . v
m = p / v
m = (72 kg.m/s) / (9 m/s) = 8 kg
An object with a velocity (v) of 9 m/s and a linear momentum (p) of 72 kg.m/s, has a mass (m) of 8 kg.

Answer:
The speed of light is that medium is 281907786.2 m/s.
Explanation:
since the critical angle is Фc = 430, we know that the refractive index is given by:
n = 1/sin(Фc)
= 1/sin(430)
= 1.06
then if n is the refractive index of the medium and c is the speed of light, then the speed of light in the medium is given by:
v = c/n
= (3×10^8)/(1.06)
= 281907786.2 m/s
Therefore, the speed of light is that medium is 281907786.2 m/s.
Answer:
- Time delta is associated with difference in wavelengths
Explanation:
When pulsating radio waves consisting of different wavelengths pass through the ionized gas in interstellar space, the fast oscillating radio waves travel relatively faster than the slowly oscillating radio waves. As a result radio waves get dispersed and there is a time difference between the radio waves with different wavelength when the pulses arrive.
Answer:
his acceleration is 3.25
Explanation:
because you do 26÷16 which =1.625×2=3.25
