The variables that show a direct relationship are :
- The speed of a car and the distance traveled
- Number of students in a cafeteria and the amount of food consumed
- The distance a planet is from the sun and that planet's temperature
- The mass of a space shuttle and its acceleration through space
In direct relationship, when one factor is increased/decreased , it will directly cause the other factor to be increased/decreased
The greater the energy, the larger the frequency and the shorter (smaller) the wavelength. Given the relationship between wavelength and frequency — the higher the frequency, the shorter the wavelength — it follows that short wavelengths are more energetic than long wavelengths.
Answer:
The answer is "512 J".
Explanation:
bullet mass 
initial speed 
block mass
initial speed
final speed 
Let
will be the bullet speed after collision:
throughout the consevation the linear moemuntum
The kinetic energy of the bullet in its emerges from the block


Explanation:
First convert the speed into m/s and time into seconds
i believe i could be wrong but i think its kinetic energy.
