7 0

Answer:

18 neutrons

Explanation:

Potassium is nuimber 19 on periodic table, so when the mass equals 37, you simply subtract 37-19 to get 18

potassium usually has a mass of 39, so when we have potassium 37, it is two less neutrons than normal

UDAY WAS TOLD TO PUT SOME CONTAINERS IN ONE OF THE COLD STORES AT WORK. THE LABLES ON THE CONTAINERS READ STORE BELOW -5 C.THERE

Alja [10]

He should choose the room that’s 15 F.

-5 C = 23 F
Meaning that 15 F is below -5 C and 25 F is not.

A proton is accelerated down a uniform electric field of 450 N/C. Calculate the acceleration of this proton.

olasank [31]

Answer:

The acceleration of proton will be $431.137\times 10^8m/sec^2$

Explanation:

We have given electric field E = 450 N/C

Charge on proton $=1.6\times 10^{-19}C$

Force on electron due to electric field is given by $F=qE=1.6\times 10^{-19}\times 450=720\times 10^{-19}N$

Mass of electron $m=1.67\times 10^{-27}kg$

Now according to second law of motion $F=ma$

So $720\times10^{-19}=1.67\times 10^{-27}a$

$a=431.137\times 10^8m/sec^2$

So the acceleration of proton will be $431.137\times 10^8m/sec^2$
