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

the answers the correct one is: the time increases

Explanation:

When an insulating material is placed in the cavity of a wall the thermal conductivity of the system increases, therefore the temperature changes take longer.

P= dQ / dt = K A dT / dx

when placing insulation the value of k is less

When reviewing the answers the correct one is: the time increases

In projectile motion on Earth, the horizontal component of gravitational acceleration is

kipiarov [429]

In projectile motion the horizontal component is not affected by gravity. You split the motion in horizontal and vertical motion. The horizontal will be an uniform motion, with v being constant. While the vertical will be an uniform accelerated motion, with the acceleration being the gravity.
