Answer:
The escape speed of the planet is 41.29 m/s.
Explanation:
Given that,
Speed = 52.9 m/s
Final speed = 32.3 m/s
We need to calculate the launched with excess kinetic energy
Using formula of kinetic energy
We need to calculate the escape speed of the planet
Using formula of kinetic energy
Hence, The escape speed of the planet is 41.29 m/s.
Gas and solar power I think

Answer:
a. Temperatures increase can change a solid to a liquid, but cannot change a liquid to a solid
b. The particles in a solid are much closer together than the particles in a liquid.
Explanation:
Any material expands when heated and contracts when cooled. So, when a body is heated to a particular temperature, it starts melting and changes into a liquid.
As the material expands the distance between the atoms or molecules increases and it will become a liquid. So it can move around the material. It doesn't become solid on further heating. But water is an exception where it contracts when heated from 0° to 4° C.
In solids, these atoms or molecules are closely packed. It is rigidly fixed.
The solid, as well as the liquid, has a definite volume, but the liquid does not have a definite shape.
Answer:
306.08 kPa
Explanation:
Given data
Average stress of first wave = 3811 kPa
amplitude of first wave ( A1 ) = 430 kPa
Frequency of first wave = 6 Hz
<u>Determine the average stress of the second sinusoidal component in kPa </u>
Amplitude of the additional wave (A2add) = = 430 / 2 = 215 kPa
next we will determine the resultant amplitude of the second wave
A2 =
=
=
= = 480.79
hence the average stress of the second sinusoidal component
=
= = 306.08 kPa
