I think the one that is most needed for cosmologist to study the age of the universe is : D. distance travelled
It is used to determine the Hubble constant  today and extrapolating back in time with the observed value of density parameters

Hope this helps

A 2 kg marble moving at 4 mi./s collides into a 1 kg marble at rest. After collision, the 2 kg marble speed decreased to 2 mi./s
Klio2033 [76]

Answer:

2\sqrt{6}  \frac{mi}{s}

Explanation:

Assuming there is no waste of energy:

K_{1} = K_{2}\\\frac{1}{2}m_{1}v_{1_{1}}^{2} + \frac{1}{2}m_{2}v_{2_{1}}^2 = \frac{1}{2}m_{1}v_{1_{2}}^{2} + \frac{1}{2}m_{2}v_{2_{2}}^2\\\\=> m_{1}v_{1_{1}}^{2} + m_{2}v_{2_{1}}^2 = m_{1}v_{1_{2}}^{2} + m_{2}v_{2_{2}}^2\\\\m_{1} = 2 kg, m_{2} = 1 kg, v_{1_{1}} = 4 \frac{mi}{s} , v_{2_{1}} = 0\\=> 32 = 8 + v_{2_{2}}^{2} => v_{2_{2}} = 2\sqrt{6} \frac{mi}{s}

Salsk061 [2.6K]
  • Mass=m=25kg
  • Height=h=10m
  • Acceleration due to gravity=g=10m/s^2

\boxed{\sf E_P=mgh}

\\ \sf\longmapsto E_P=25(10)(10)

\\ \sf\longmapsto E_P=25(100)

\\ \sf\longmapsto E_P=2500J
