Energy because only the energy moves ahead.
Answer:
Orbital period, T = 1.42 years
Explanation:
It is given that,
Orbital period of a solar system planet,
The orbital period of the planet can be calculated using third law of Kepler's. It is as follows :
M is the mass of the sun
r = 1.42 AU
So, the solar-system planet that has an orbital period of 8 years would have an orbital radius of about 1.42 AU.
The equation that she will use to calculate the specific heat capacity is Q/(mΔθ).
<h3>What is specific heat capacity?</h3>
Specific heat capacity is the quantity of heat required to raise 1 kg unit mass by 1 kelvin temperature.
Q = mcΔθ
where;
- Q is quantity of heat required
- m is mass of the water
- c is the specific heat capacity
- Δθ is change in temperature = 75 - 25 = 50°C
c = Q/(mΔθ)
c = (90,000) / (350 x 50)
c = 5.143 J/g°C
Thus, the equation that she will use to calculate the specific heat capacity is Q/(mΔθ).

Wave A has a higher amplitude than Wave B.
B) 200 km/h
Each car is traveling at 100 km/h, so you add the speeds to gether since they are traviling in opposite directions.
