Answer:
I believe the answer is A and D.
I am unsure of C.
A. atoms fuse in the sun, but atoms break up in nuclear power plants.
The process in the Sun is a Fusion Process, atoms are fused, while the process in nuclear power plant is a Fission Process, atoms break up.
Answer: B = surface waves
Explanation:
Transverse and longitudinal waved combined make surface waves.
would'nt mind if you click the brainliest button lol ;)
Answer:
a-
50°C whn converted into K - 323 K
Answer:
Acceleration is the rate of change of velocity. What is commonly said as ‘ten meter per second squared’ can bee broken down into ‘ten meter per second per second.’ This gives us the true meaning of the term acceleration.
Just like ‘ten meter per second’ means increasing the displacement by ten meters every second, ‘ten meter per second per second’ means increasing the velocity by ten meters per second every second.
So, basically if you consider the case of a free fall motion, where ‘t’ stands for time and ‘v’ stand for velocity at that instant:
At,
t=0, v=0 m/s
t=1, v=0+10 m/s;
t=2, v=0+10+10 m/s;
t=3, v=0+10+10+10 m/s;
This can also be thought as a Arithmetic Progression where common difference ‘D’ is the acceleration(a), since it adds a 10 m/s to velocity every second and the first term ‘A’ stands for the initial velocity (u). Using this approach we can derive to the first equation of motion:
v = u + at
