Increasing mass increases kinetic energy. This can be seen in the equation KE = 1/2 (m) (v)^2

Answer:
Temperature=3.86*10^7K
V1=1.4
Explanation:
Deuterium (2H), when heated to sufficiently high tempera- ture, undergoes a nuclear fusion reaction that results in the production of helium. The reaction proceeds rapidly at a temperature, T, at which the average kinetic energy of the deuterium atoms is 8 × 10216 J. (At this temperature, deu- terium molecules dissociate completely into deuterium atoms.)
(a) Calculate T in kelvins (atomic mass of 2H 5 2.015).
(b) For the fusion reaction to occur with ordinary H atoms, the average energy of the atoms must be about 32 × 10216 J. By what factor does the average speed of the 1H atoms differ from that of the 2H atoms of part (a)?
k.E =3/2kT
K.E is the kinetic energy
k=boltzmann constant
T=Temperature in kelvin
juxtaposing the given values we have
T=2(KE)/3k
T=2*8*10^-16/(3*1.38*10^-23)
T=3.86*10^7K
Temperature=3.86*10^7K
b. average speed V=
R is the gas constant
T absolute temperature in kelvin
M molar mass
since R.T,PI are constant
we are comparing between hydrogen and helium particles
V=
V1/V2=
V1=V2
V1=V2* 1.4
V1=1.4
A. The amount of water. 50/50
Answer:
412.1 N
Explanation:
First of all let's calculate the total speed of the ball as it is released, which is equal to the speed of the ball + the speed of the bowler:
Now let's convert it into m/s. We know that
So
And now we can calculate the centripetal force, which is given by:
where
m = 0.16 kg is the mass of the ball
v = 40.6 m/s is the speed of the ball
r = 0.64 m is the radius of the circular path (equal to the length of the bowler's arm)
Substituting:
If a violin string vibrates at 430 hz as its fundamental frequency,then the frequencies of the harmonics are 880, 1320, 1760
The frequency in physics is the number of waves passing a fixed location in a unit of time. It also indicates how many cycles or vibrations a body in periodic motion experiences in a given unit of time.
How frequently something occurs is what is meant by the word frequency. A person blinking their eyelids 47 times in a minute is an example of frequency. the quality or state of happening frequently.
Integer (whole-number) multiples of the fundamental frequency are used to define harmonics, which are voltages or currents that function at certain frequencies. This means that for a waveform with a fundamental frequency of 50 Hz, the second harmonic frequency would be 100 Hz (2 x 50 Hz), the third harmonic would be 150 Hz (3 x 50 Hz), etc.
