Answer:
28.295244 MeV
Explanation:
= Mass of proton = 1.007276 u
= Mass of neutron = 1.008665 u
= Mass of electron = 0.000549 u
Mass of reactant is 4.002604 u
Mass of the products is

(2 because there are 2 of each)
The difference in mass is

So, the work done in MeV would be

The work done required to completely disassemble all the helium is 28.295244 MeV
Answer:
4
Explanation:
Waves that are squished have higher frequency. It has short wavelength.
You already told us that its speed is constant. That's one part of acceleration.
The other part of acceleration is the direction it's moving.
If it's rolling in a straight line, then there's no acceleration.
If it's curving left or right, then that's acceleration.
K.E = 1/2 mv²
800 = 1/2 ×12 ×v²
800 = 6 v²
800 / 6 = v²
= 133.4 =v²
√133.4 = √v²
11.5 = v²
I hope this answer is correct.
Answer:
337k
Explanation:
First, let us find the difference between the given two temperatures.
Difference = 85°C - 21°C
= 64°C
<u>And now we have to write the temperature in kelvins.</u>
To convert Celcius to Kelvins you can add 273 to the temperature in Celcius.
<u>Let us find it now.</u>
64°C + 273 = 337k
Therefore,
64°C ⇒ <u>337k</u>
