The gravitational field is the Force divided by the mass
Call g the gravitational fiel, F the force exerted by the earth and m the mass of the telescope.
g = F / m
g=9.1x10^4 N / 1.1 x 10^4 kg = 8.27 N/kg
Note that the unit N/kg is equivalent to m/s^2
<span>C. free electrons. Plasma is made up of atoms. The atoms have had some or all of the electrons stripped away. The nuclei are positively charged and are called ions. The ions roam freely. Gases are made up of both molecules and atoms.</span>
Answer:
F = 5291.25 N
Explanation:
F = Ma so 1245 times 4.25^2 ,, that equals 5291.25 N
Explanation:
Use half life equation:
A = A₀ (½)^(t / T)
where A is the final amount,
A₀ is the initial amount,
t is time,
and T is half life.
0.375 = 3 (½)^(1 / T)
0.125 = (½)^(1 / T)
(½)^3 = (½)^(1 / T)
3 = 1 / T
T = 1/3 hours
T = 20 minutes
