If an object's acceleration is really zero, then its speed
is constant, and it's moving in a straight line.
Answer:
Charles' Law
Explanation:
When pressure is held constant the volume of a mass of gas is directly proportional to its temperature.
The asker of the second question needs a tutorial in radiometric dating. There is little likelihood that the daughter isotope has the same atomic weight as the parent isotope. To measure the mass isotopes doesn't tell us how many atoms of each exist. To get around that let's pretend — which will likely serve the purpose ineptly intended — that the values give an the particle ratio, 125:875.
<span>The original parent isotope count was 125 + 875 = 1000. The remaining parent isotope is 125/1000 or 1/8. 1/8 = (1/2)^h, where h is the number of half-lives. </span>
<span>h = log (1/8) ÷ log(1/2) = 3 </span>
<span>And 3 half-lives • 150,000 years/half-life = 450,000 years.</span>

Answer:
a) T = 2.997 s
b) K = 14.3 J
c) φ = 0.444 rad
Explanation:
a) Determine its period
The pendulum simple’s period is:
T = 2π
Where l: Pendulum’s length
g = 9.8 m/s2
T = 2π
T = 2.997 s
b) Total energy
Initially his total energy is kinetic
K = 
K = 
K = 14.3 J
c) Maximum angular displacement
φ = 
φ = 
φ = 0.444 rad
