What is the difference between time and velocity

1 answer:

7 0

There are loads of similarities, but there are differences and that's what you want!

Speed- Is usually referring to how fast an object moves, it is calculated by space per unit.

Velocity- Refers to the rate at which said object changes position in a certain direction. Usually calculated by the displacement of space per unit.

SO it sounds the same, but simple answer Velocity deals with direction, and speed does not!

Two students, Nora and Allison, are both the same age when Allison hops aboard a flying saucer and blasts off to achieve a cruis

White raven [17]

Answer:

23.38 years

Explanation:

Speed of Allison = 0.83 c = v

Time passed according to Allison = Δt = 29.5 years

Time dilation

$\Delta t'=\frac{\Delta t}{\sqrt{1-\frac{v^2}{c^2}}}\\\Rightarrow \Delta t'=\frac{29.5}{\sqrt{1-\frac{0.83^2c^2}{c^2}}}\\\Rightarrow \Delta t'=\frac{29.5}{\sqrt{1-0.83^2}}\\\Rightarrow \Delta t'=52.88\ years$

For Nora 52.88 years would have passed

So, their age difference would be 52.88-29.5 = 23.38 years

Well, i would tell the kid that light is electromagnetic radiation which is visible. The frequency and wavelength is just right so the radiation becomes visible, and that visible radiation goes away from the star and reaches earth It also depends on the age of the child and the comprehension level
