An atomic physicist determines that an atom is composed of 8 positively charged particles and has a mass of 15 amu. which is the
best conclusion that can be drawn? 1.the atom has 7 neutrons and 8 protons. 2. the atom has 7 electrons and 8 protons. 3. the atoms has 8 neutrons and 7 electrons. 4. the atoms has 8 electrons and 7 protons.
<span> 1.the atom has 7 neutrons and 8 protons....
because the positively charged particles are the protons ...and 8 is also the atomic number ...so number of neutrons can be calculated by subtracting </span>atomic number from the mass number...which gives us the neutrons 7 ...
No "might<span>". The amount of CO2 in the </span>atmosphere<span> HAS gone up since the start of industrialisation as the result of </span>burning fossil fuels<span>.</span>
You already have the speed, now you need the time. I will use the formula for speed which is S=D/T. S=Speed D=Distance T=Time. So here we have, 18m/s = 52m/T we do 18 divided by 52 which would be .3461. .3461 seconds is how long it took the stone to reach the water.
