Which of the following will result in the highest conductance ? A. Large cross-sectional area, short pipe
B. Large cross-sectional area, long pipe
C. Small cross-sectional area, short pipe
D. Small cross-sectional area, long pipe
Answers
Answer:small cross-section area,long pipe
Explanation:
Conductance is a measure of how easily the current can flow through a electrical component.
It is the inverse of resistance.
Conductance is given by
where is conductivity(constant for a component),
is the length of component parallel to the flow and
is the area of cross-section of the component perpendicular to the flow.
So,conductivity increases with increase in and decreases with increase in
So,small cross-sectional area and long pipe has high conductance.

After the initial push, the rock will keep moving forever at constant velocity (constant speed in a straight line)
Explanation:
We can answer this question by using Newton's first law of motion:
"An object at rest (or in motion at constant velocity) will stay at rest (or will keep moving at constant velocity) unless acted upon unbalanced forces" (Law of inertia)
In this problem, we have a rock in a place very far from any force that can act on it. This means that there are no unbalanced force acting on it, so the rock will keep its state of motion forever.
In this situation, the rock is initially thrown by the astronaut. After the initial push, which accelerates the rock up to a certain velocity, there will be no more forces acting on the rock. This means that the rock will continue moving at a constant velocity forever, so at a constant speed in a straight line.

A stained glass window usually has several sections to it,
and they handle light differently.
-- The sections that are completely clear, and if you look
through one of them you can see the cars outside in the
parking lot, are transparent.
-- The sections that are milky, and light comes through them
but if you look through them you can't see the shapes of cars
or people, are translucent.
-- The sections that are so heavily stained or tinted that they
look completely dark are opaque.

The x-component of the vector is 36.55 m.
Components of vectors
The components of a vector include both x and y components. The x-component is determined along x-axis, while y-component is determined along y-axis.
Vx = Vcosθ
Vy = Vsinθ
where;
- Vx is the x-component of the vector
- Vy is the y-component of the vector
X-components of the vector
The x-component of the vector is calculated as follows;
x = 47.3 x cos(39.4)
x = 36.55 m
Thus, the x-component of the vector is 36.55 m.

A) the piano lost mass as it was pushed up the ramp.
B) energy was destroyed moving the piano up the ramp.
C) some of the energy required to push the piano up the ramp was used to overcome friction between the piano and the ramp.
D) the work required to push the piano up a ramp is greater because the force is the same as if it were lifted, but the distance is greater when using a ramp.

Answer: To complete the process of digestion after the food is ingested by mouth.
Explanation:
The food that we eat is ingested by mouth and here the mechanical degradation of food takes place. This breaks down the food into smaller pieces.
Mouth also contains the enzyme that is responsible for the digestion of starch.
Then the food from the mouth reaches the stomach where various types of digestive juices and enzymes are secreted to digested the food.
Hence, mouth and stomach must be near in the digestive system.
