The weight of the child is 210 N, which is equivalent to approximately 21.4 kg because 1 N is equivalent to 0.102 kg in Earth's gravity. Mass is a measure of the amount of matter in an object, so the mass of the child would also be 21.4 kg.
The athlete with a mass of 100 kg will have greater momentum because momentum is directly proportional to mass. Both athletes have the same velocity, so the athlete with the larger mass will have the greater momentum.
The symbol Po-210 represents the isotope of Polonium with a mass number of 210.
You can solve this in two ways.1) Trial and error. That is, try multiplying two consecutive integers; if the product is too large, try smaller integers; if the product is too small, try larger consecutive integers. 2) Call the two consecutive integers "n" and "n+1", and solve the equation: n(n+1)=210
They are numbers of the form 210 + 2*n where n = 1, 2, 3, ... 15.
Polonium-210 has 126 neutrons.
There are 210 In-n-Outs in California according to the In-n-Out website.
Number of neutrons = Mass number - atomic number = 210 - 82 = 128
4n/15 + n/14 = (4n x 14 + 15n)/210 = 71n/210
The ratio is N:21
The mass of one staple is 0.032 grams. This can be found by dividing the total mass of 210 staples (6.80 grams) by the number of staples (210).
Polonium is a metal element. Atomic mass of it is 209.
