What happens when there is a change in pressure at any point in a fluid

Answers

A change in pressure applied to an enclosed fluid is transmitted undiminished to every point of the fluid and to the walls of the container. This is a statement of Pascal's Principle, which is the basis of the hydraulic jack you see lift cars at the garage.

How could a lightbulb near an electromagnet, but not touching it, be lit? Is ac or dc required? Defend your answer.

Answers

Answer:

If the light bulb is connected to a wire loop that intercepts changing magnetic field lines from an electromagnet, voltage will be induced which can illuminate the bulb. Change is key, so to stay lit the electromagnet should be powered with AC.

Explanation:

In a physics experiment, two equal-mass carts roll towards each other on a level, low-friction track. One cart rolls rightward at 2 m/s and the other cart rolls leftward at 1 m/s. After the carts collide, they couple (attach together) and roll together with a speed of __________. Ignore resistive forces.a. 0.5 m/sb. 0.33 m/s
c. 0.67 m/s
d. 1.0 m/s
e. none of these

Answers

Answer:

The correct answer is option a.

Explanation:

Conservation of momentum :

$m_1u_1+m_2u_2=m_1v_1+m_1v_2$

Where :

$m_1, m_2$ = masses of object collided

$u_1,u_2$ = initial velocity before collision

$v_1,v_2$ = final velocity after collision

We have :

Two equal-mass carts roll towards each other.

$m_1=m_2=M$

Initial velocity of $m_1=u_1=2 m/s$

Initial velocity of $m_2=u_2=-1 m/s$ (opposite direction)

Final velocity of $m_1=v_1=v$ (same direction )

Final velocity of $m_2=v_2=v$ (same direction)

$M* 2 m/s+M(-1 m/s)=Mv+Mv$

$1 m/s=2v$

v = 0.5 m/s

The speed of the carts after their collision is 0.5 m/s.

An insect is able to walk across the surface of a pond without sinking because of the A. polarity of the water molecules.
B. process of evaporation.
C. surface tension of the water.
D. adhesion of the insect's feet to the surface of the water.

Answers

C. surface tension of the water.

the answer to that will be D because it has nothing at all to do with the water because either way the water shall stay the same if the animal or insect could or could not be able to walk on water.
