The average speed of the football is 15 meters per second. Just divide both of the numbers by 4 :)
Answer:
Inertia
Explanation:
Inertia is the inherent property of an object to remain in its state of rest or motion without being disturbed.
For an object at equilibrium :
.option D: It might be stationary.
.option E: Fnetx must be zero, Fnetx can be anything.
What is equilibrium?
This refers to a state in which an object is at rest or balanced to the equal action of opposing forces.
At equilibrium, in the presence of external forces, the opposite forces normally have a balanced effect on the object in concern. Objects at equilibrium are known for their stable nature in terms of motion and energy.
Conditions for equilibrium
.The object must have no acceleration.
.The total force acting on the body i.e the net force and the net torque on the object must be zero.

Answer:
Hello Adam Here! :D
Explanation:
A scalar quantity is defined as the physical quantity that has only magnitude, for example, mass and electric charge. On the other hand, a vector quantity is defined as the physical quantity that has both magnitude as well as direction like force and weight. The other way of differentiating these two quantities is by using a notation.
OH YEAH! XD
Answer:
Final volumen first process
Final Pressure second process
Explanation:
Using the Ideal Gases Law yoy have for pressure:
where:
P is the pressure, in Pa
n is the nuber of moles of gas
R is the universal gas constant: 8,314 J/mol K
T is the temperature in Kelvin
V is the volumen in cubic meters
Given that the amount of material is constant in the process:
In an isobaric process the pressure is constant so:
Replacing :
Replacing on the ideal gases formula the pressure at this piont is:
For Temperature the ideal gases formula is:
For the second process you have that So:
