Answer:
its In most solids, conduction takes place as particles vibrate in place.
Explanation:
i did it in a test
Answer:
speed of the arrow as it leaves is 41.05 m/sec
Explanation:
We have given mass m = 0.285 kg
Average force F = 182 N
Distance traveled d = 1.32 m
We know that work done = force distance
Sp work done =
Now according to work energy theorem work done will be equal to kinetic energy
So
v = 41.05 m/sec
So speed of the arrow as it leaves is 41.05 m/sec
This is the order of the spectrum from highest frequency to lowest frequency:
Gamma Ray (Highest energy em wave)
X Ray (Used in medical imaging)
Ultra violet (dangerous to human skin)
visible light (human eye can see)
Infrared (medium frequency)
Microwave (used to heat food)
Radio (longest wavelength)
The correct answer is
B It increases.
In fact, the kinetic energy of a moving object is given by
where m is the mass of the object and v is its speed. We see that the kinetic energy is proportional to the mass and proportional to the square of the speed: in this problem, the speed of the object remains the same, while its mass increases, therefore the kinetic energy will increase as well.
