Because the four outer planets are comprised of mostly gases give me a thanks or brainiest answer if this helps!
a = dv/t = (330-x)/1.5 =50
x= 330-75 = 255 m/s
Intial velocity 255 m/s
Answer:
Heat is the energy that flows between two substances of different temperatures.
Explanation:
Heat is a type of energy in transition that is transferred by non-mechanical means between systems, which means that it is energy that is transferred (or that <u>flows </u>) from one system to another.
This flow of energy occurs due to a temperature difference, and heat will flow from the system or substance with a higher temperature to the substance with a lower temperature, and if kept in contact they will eventually reach the thermal equilibrium.
So the correct answer is: Heat is the energy that flows between two substances of different temperatures.
Answer: 
Explanation:
The rest of the question is below:
Find a2, the magnitude of the centripetal acceleration of the star with mass m2.
Assuming both stars are describing a uniform circular motion, their acceleration vector is directed towards the center of mass of the system (that's why it's called centripetal acceleration).
Now, according to Newton's 2nd law, the force 
is directly proportional and in the same direction as the acceleration.
For 
:
For 
:
If the centripetal force is the same for both stars:
Isolating 
:
An object of mass m attached to a spring of force constant k oscillates with simple harmonic motion. The system's potential energy when kinetic energy of (3/4) E is (1/8) k A².
<h3>What is mechanical energy?</h3>
Mechanical energy is the sum of potential energy and kinetic energy.
Total mechanical energy = P.E max = K.E max
Total mechanical energy = K.E +P.E
Given is the kinetic energy is (3/4)E.
E= (3/4)E + P.E
P.E = (1/4) E
Maximum potential energy =E = (1/2) k A²
Here. A is the maximum displacement and k is the spring constant.
The potential energy at kinetic energy of (3/4) E is
P.E = (1/4)E = (1/8) k A²
Therefore, the system's potential energy when kinetic energy of (3/4) E is (1/8) k A².
