Yo sup??
The weight vector is usually drawn vertically downwards from the centre of the body.
It can be respectively resolved as well.
Hope this helps
<span> Atmospheric pressure decreases with altitude is because of gravity . The more you are away from the surface, the less atmosphere you have above you. The relationship between the atmospheric pressure and altitude depends on the mass of the planet.

Answer:
The weight of the body in the new planet is 100 newtons.
Explanation:
From Newton's Law of Gravitation we find that gravitational force is directly proportional to mass of the planet and inversely proportional to the square of its radius. From this fact we can build the following relationship:
(1)
Where:
, 
- Gravitational force, measured in newtons.
, 
- Mass of planet, measured in kilograms.
, 
- Radius of the planet, measured in meters.
If we know that 
, 
and 
, then the expected gravitational force in the new planet is:
The weight of the body in the new planet is 100 newtons.
Explanation:
Solution,
Volume (v)=287 cm^3
Mass(m)=816 g
Density(d)=m/v
=816/287
=2.84
So, the density of the block of marbles is 2.84 g/cm^3.

Answer:
The answer is below!!
Explanation:
Electromagnetic radiation (e.g., radio, microwaves, light) can be modeled as a wave of changing electric and magnetic fields or as particles called photons. The wave model is useful for explaining many features of electro-magnetic radiation, and the particle model explains other features.
