A stone is dropped from a tower 100 meters above the ground. The stone falls past ground level and into a well. It hits the wate
r at the bottom of the well 5.00 seconds after being dropped from the tower. Calculate the depth of the well. Given: g = -9.81 meters/second2. 22.5 meters 50.7 meters 100 meters 110 meters 152.45 meters

Answer:
v_y = 14.55 m/s
Explanation:
given,
height at which gull is flying = 10.80 m
speed of the gull = 6 m/s
acceleration due to gravity = 9.8 m/s²
Relative to the seagull, the x-speed is 0,
because the seagull has the same x-speed.
Only the y-speed counts:
v_y = 14.55 m/s
hence, the speed at which the clam smash the rock is v_y = 14.55 m/s
Explanation:
A chemical reaction is a reaction in which two or more species combine together to form a molecule with a new chemical composition.
In a chemical reaction, the reactants are written on left hand side pointing a forward arrow towards the products which are written on the right hand side.
For example, chemical reaction between hydrogen and oxygen will result in the formation of water. The reaction equation will be as follows.
