2 gram piece of iron, because is doesn't float.
Vf = Final velocity.
Vi = initial velocity
a = acceleration.
t = time
Vf = Vi + at
Vf = 0 + (2 m/s^2)(3s)
Vf = 6 m/s south
Explanation:
The pressure exerted in the fluid at that depth is given by :
..............(1)
Where
is the density of the fluid
g is the acceleration due to gravity
h is the depth of the fluid
It is clear from equation (1) that the pressure exerted in the fluid is directly proportional to the depth in a fluid. As the depth increases, the pressure will also increase.
Answer:
Energy: The ability to do work
Kinetic energy: Kinetic energy is the energy an object has due to its motion
Potential energy: potential energy is the energy that is stored in an object
Work: Work is the transfer of energy by a force acting on an object as it is displaced
Friction: Friction acts as a resisting force which is generated , when two solid surfaces slide against one another
The velocity of an object determines if it is moving. If the velocity is zero, it is not moving. If it has a positive velocity, then it is moving forward. If it has a negative velocity, then it is moving backwards.
