Hello!
First one we can use that PE=mgh so we have
4.37*10^5J/(9.12*10^3kg*9.80m/s^2)= 4.89m
Second one we can use Newton’s Second Law
F=ma and in this case F=mg so we have
g= 3.28*10^-2N/6*10^-3kg = 5.47m/s^2
Hope this helps. Any questions please ask. Thank you.
I think it's 16.8 because you multiply 5.6x3=16.8
I think you go to my school!
Magnesium is in group 2 while sulfur is in group 6.
the group number determines the number of valence electrons.
Metals gives lose electrons (mg)
Non Metals gain electrons (s)
answer: Magnesium gives 2 electrons to sulfur.
Mg is now 2.8
Sulfur is 2.8.8
cuz ionic bonding
Alpha particles are released by proton rich unstable nuclei. It has no electrons to balance the protons making it positively charged particles moving at very high speeds. Gamma articles are electromagnetic waves of short wavelength and high frequency. It has a speed same as the speed of light. Beta particles are released by neutron rich unstable nuclei. It has a speed of less than the gamma particles.
