Answer:
Astral projection is a term used in esotericism to describe an intentional out-of-body experience that assumes the existence of a soul or consciousness called an "astral body" that is separate from the physical body and capable of travelling outside it throughout the universe.

Answer:50</h2>
Explanation:
Let be the airspeed.
Let be the cross wind speed.
We know that,ground speed is the vector sum of airspeed and cross wind speed and airspeed is perpendicular to cross wind speed.
If and are two perpendicular vectors,the resultant vector has the magnitude
Given,
So,the ground speed is

Answer:
E = 73.5 J
Explanation:
Given that,
Mass of a marble, m = 5 kg
It is placed at the edge of a 1.5 m table
We need of find the gravitational potential energy of the marble. It is given by the formula as follows :
E = mgh
E = 5 kg × 9.8 m/s² × 1.5 m
E = 73.5 J
So, the potential energy of the marble is 73.5 J.
From the information given, there is a 15 kg mass that needs to be accelerated to a velocity of 2.8m/s²
We use the formula: F = m × v.
Where F = force, m = mass and v = velocity.
In our case, m = 15kg and v = 2.8m/s². Therefore:
F = m × v.
F = 15 × 2.8.
F = 42.
Therefore the net force needed to accelerate the 15kg mass to 2.8m/s² is 42 kg m/s² (or 42 Newtons)
