Answer:
Explanation:
In the image attached with this answer are shown the given options from which only one is correct.
The correct expression is:
Because, if we derive velocity with respect to time we will have acceleration , hence:
Where is the mass with units of kilograms () and with units of meter per square seconds , having as a result
The other expressions are incorrect, let’s prove it:
This result has units of
This result has units of
This result has units of and is a constant
This result has units of
This result has units of
This result has units of and is a constant
This result has units of and is a constant
because is a constant in this derivation respect to
This result has units of and is a constant
Answer:
12 units
Explanation:
This problem can be solved if we take into account the equation for a sphere
where we took that the radius is 13 units. If we take z=5 and we replace this value in the equation of the sphere we have
where we have taken x2 +y2 because if the equation of a circunference.
In this case the intersection is made when we take z=5, for this value the sphere and the plane coincides in values.
Hence, the radius is 12 units
I hope this is useful for you

I believe the correct answer from the choices listed above is option C. A group of students is asking people whether they use plastic bags. By doing such, the students are <span>collecting data. They are collecting data of how many people uses plastic bags. Hope this answers the question.</span>
Kinetic Energy is defined by 1/2 times the mass times the velocity squared.
KE = (1/2)mv2
Thus, a swinging pendulum has its greatest kinetic energy and least potential energy in the vertical position, in which its speed is greatest and its height least; it has its least kinetic energy and greatest potential energy at the extremities of its swing, in which its speed is zero and its height is greatest.
