Answer:
B
This is because frictional energy is similar to thermal energy in a system. Therefore the thermal energy produced is equal to
Answer:
A motion diagram represents the motion of an object by displaying its location at various equally spaced times on the same diagram. Motion diagrams are a pictorial description of an object's motion. They show an object's position and velocity initially and present several spots in the center of the diagram.
Explanation:
Fluid Dynamics is an area of research that started a long time ago, along with Calculus. It combines techniques of Mathematical Analysis and of Dynamical Systems, such as Bifurcation Theory, among others.
<h3>What is surface tension?</h3>
Surface Tension is a phenomenon that occurs in all liquids, it is characterized by the formation of a kind of elastic membrane at its ends.
<h3>How to calculate the contact angle?</h3>
Contact angles in powders can be measured using the sessile drop measurement in the compressed powder or using the force tensiometer with the Washburn method.
In fluid dynamics, the variables of surface tension, viscosity and contact angle are treated. When dealing with viscosity we have fluid can be viscous or a real fluid. In general, fluids are viscous.

Answer:

Explanation:
The equation for the linear impulse is as follows:

where
is impulse,
is the force, and
is the change in time.
The force, according to Newton's second law:

and since 
the force will be:

replacing in the equation for impulse:

we see that
is canceled, so

And according to the problem
,
and the mass of the passenger is
. Thus:



the magnitude of the linear impulse experienced the passenger is 
Answer:
x = 102.33 m
Explanation:
Given that,
Position where a forest ranger stands is 35 m above the ground. The angle of depression to the base of the fire is 20. We need to find how far from the tower is the fire.
Let the distance is x. We can find x using trigonometry as follows :

Hence, the fire is at a distance of 102.33 m from the fire.
