The angle(s) that it will reflect will be at any angle between -90° and 90. The correct answer between all the choices given is the fourth choice or letter D. Lmk if this is correct
Answer:
The velocity is
Explanation:
From the question we are told that
The side of the cube is
The mass of the object is
The density of the object is
Generally the volume of the object according to the moving observer is mathematically represented as
Therefore the length of the side as observed by the observer on high speed is mathematically represented as
Now the original length of side is mathematically represented as
Where c is the speed of light with value
So
=>
=>
Answer:
E= 3.186 * J
Explanation:
mass of atom =m=3.54 × kg.
speed of light =c= 3*
energy equivalence=E= ?
E =m c²
= 3.54 × *
E= 3.186 * J
