In projectile motion we can say initial components of velocity is


now here horizontal motion is uniform motion as there is no force in this direction while in vertical direction due to gravity it will accelerate
so we have


so here we have x and y coordinates are related to each other as it will take same time to move the positions
so here correct options are
<em>Projectile motion is a combination of horizontal and vertical motion.
</em>
<em>The horizontal and vertical motions of a projectile are dependent on each other.</em>
Answer:
Heat can be transferred in 3 ways.
Explanation:
Conduction- The process of transmission of heat in solids,without the actual movement of particles.
Convection- A process of transmission of heat in fluids (liquids and gases)with the actual movement of particles.
Radiation- It is the process of transmission of heat without any medium.
Nicholas Copernicus correctly assumed that the planets revolved around the sun but he incorrectly assumed that the planets followed a perfect circle orbit around the sun. It was later on discovered by Johannes Kepler that the planets moved around the sun following an elliptical orbit.
