Semi anthracite has the higest which is 29.5
I can only help you with the last two questions from lesson 5.01
-Because light is the fastest thing in our universe you can calculate the distance by how much time light has to take in order to travel that distance which is light years
-Light years, and every measurement you can think of. Except light years are the easiest most efficient way to measure distances
Okay... so here's what happened;
A huge amount of mass is above you, squeezing down from you from all sides; that's what happened to the hydrogen gas in the core of the sun. It got squeezed together so tightly that four hydrogen nuclei combined to form one helium atom. That's called nuclear fusion. In the process, some of the mass of the hydrogen atoms is converted into energy in the form of light.

Answer:
Distance s = 90 meter
Explanation:
Given:
Initial velocity u = 0 m/s
Final velocity v = 30 m/s
Acceleration a = 5 m/s²
Find:
Distance s
Computation:
v² = u² + 2as
30² = 0² + 2(5)(s)
Distance s = 90 meter
Answer:D
Explanation:
For Rod 1
length,diameter and Tension is L, d and T
for Rod 2 length,diameter and Tension is 2L, 2d and 2T
Change in Length is given by

where P=load
L=length
A=area of cross-section
E=young's Modulus

since both are aluminium rod therefore E is common


Thus extension in both the rods are same
