56 Newtons bc w=F×D so if you divide by D on both side you get w/D=F
D. velocity
Velocity depends on speed and direction
Answer:
Electromagnetic are produced by gases and air and so much many things
Explanation:
Science teacher said I did awesome
We will have the following:
So, the force is approximately 1.85*10^-6 N.
Answer:
Protons = 50
Mass number = 119
Explanation:
A neutral of tin, Sn, has a Z value of 50 and neutrons are 69.
Z is the atomic number. The atomic number is equal to number of protons or number of electrons in an atom that is neutral i.e:
Z = PROTONS = ELECTRONS
So the number of protons = 50 since Z is 50
>>>>>>>>>>>>>>>¦
The bulk of the mass of an atom is concentrated in the nucleus. To calculate mass number, we simply sum all the elementary particles in the nucleus i.e protons and neutrons. These particles are called the nucleons.
Mass number (A) = P + N
= 50 + 69
= 119
