Heavy elements, such as iron and silicon have temperature as compared to light elements such as hydrogen and helium. a) lower b) equal c) higher

Heavier elements, such as iron and silicon have a "higher" condensation temperature as compared to the light elements such as hydrogen and helium.

Please correct me if I'm wrong!! :)

waves moving from a fast medium to a slow medium will experience a reflection as light travels more slowly than red light. total internal reflection occurs when the critical angle is.

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2
