Answer:
150N
Explanation:
formula= pressure= force/area
300pa= x/0.5
300*0.5= x
150N= x
force= 150N
Explanation:
Using kinematics,
t = 4s
u = 0m/s
a = 9.8m/s^2
Therefore v = u + at = 0 + (4)(9.8) = 39.2m/s.
Gravity<span> - is the force by which a planet or other body draws objects toward its center. The force of gravity keeps all of the planets in orbit around the sun.
Air resistance - </span>By definition, air resistance describes the forces that are in opposition to the relative motion of an object as it passes through the air. These drag forces act opposite to the oncoming flow velocity, thus slowing the object down. Unlike other resistance forces, drag depends directly on velocity, since it is the component of the net aerodynamic force acting opposite to the direction of the movement.
<span>Another way to put it would be to say that air resistance is the result of collisions of the object’s leading surface with air molecules. It can therefore be said that the two most common factors that have a direct effect upon the amount of air resistance are the speed of the object and the cross-sectional area of the object. Ergo, both increased speeds and cross-sectional areas will result in an increased amount of air resistance.</span>
Copper is a chemical element having atomic number 29 and represented by the symbol Cu.
The electron configuration of copper is 1s2 2s2 2p6 3s2 3p6 4s1 3d10 and copper will share one atom from s orbital as it can hold two electrons and form one bond with other atoms to become stable.
