Answer:
Explanation:
formula for the period of a satellite = 2π.
period of satellite A (Ta) = 2π.
period of satellite B (Tb) = 2π.
ratio of the periods of the satellites = (take note that π is shown as )
where
- Me = mass of the earth
- G = universal gravitational constant
- π = 3.142
- all the above are constants and cancel each since they are both at the numerator and denominator
- R = distance from the earth
the equation now becomes
=
- the velocity of a satellite = (take note that π is shown as )
- rearranging the above R = (take note that π is shown as )
- now substituting the above into the equation we have
= (take note that π is shown as )
2π will cancel itself from the numerator and denominator and we have
=
squaring both sides we have
=
now cross multiplying we have
from the question the velocity of satellite A is 3 times that of satellite B hence Va = 3Vb
Answer:
The speed of the center of mass of the two carts is 0.103 m/s
Explanation:
It is given that,
Mass of the air track cart, m₁ = 350 g = 0.35 kg
Velocity of air track cart, v₁ = 1.25 m/s
Mass of cart, m₂ = 280 g = 0.28 kg
Velocity of cart, v₂ = -1.33 m/s (it is travelling in opposite direction)
We need to find the speed of the center of mass of the two carts. It is given by the following relation as :
Hence, this is the required solution.
Explanation:
In order from highest to lowest energies the parts of electromagnetic spectrum are named as
Gamma rays,
X-rays,
ultraviolet radiation,
visible light,
infrared radiation,
and radio waves.
Microwaves are a subsections of radio waves. They are used in microwave ovens to heat the food items.
This is expected EM spectrum in field of science.
Answer:
4500 N
Explanation:
F = ma
= 1500 kg * 3 m/s^2 = 4500 N
