Explanation:
<u>Pressure Exerted by a Column of Liquid</u>
The pressure P exerted by a column of liquid of height h and density ρ is given by the hydrostatic pressure equation:
P = ρgh
Where ρ is the density of the liquid, g is the acceleration of gravity g=9.8m/s^2, and h is the height of the column of liquid.
The data provided is as follows:
The pressure is:
To determine which object has the greatest acceleration, you would use the formula:
acceleration = (Final Velocity - Initial Velocity) / Time
Just plug-in values for what you have and see which one has the greatest acceleration. If you're given velocity-time graphs, then the one with the steepest slope would have the greatest acceleration.
The final speed of a lion running 30 m/s accelerates at a rate of 3 m/s3 for 5 seconds it’s 3.2
Answer:
none. 0. for work to be done the object has to have displacement, and even though you were exerting force, the box did not move and s work is o it could also be 50 but I'm sure it is 0
Explanation:
Answer:
a = kL/m
Explanation:
Here we can use Hooke's Law to find out the force applied on the system. Hooke's Law states that when a spring is stretched by some force, the force applied is directly proportional to the displacement of spring. The formula is given as:
F = kL
Now, the Newton's Second Law of motion states that whenever an unbalanced force is applied to a body it produces an acceleration in the body, in its own direction. So, the force is given by the formula:
F = ma
Comparing both the forces, we get:
kL = ma
<u>a = kL/m</u>
