Answer:

Reaction force

Explanation:

A ball is thrown against a wall: The ball puts a force on the wall (action force), and the wall puts a force on the ball (reaction force) so the ball bounces off

Where must an object be placed to form an image 30.0 cm from a diverging lens with a focal length of 43.0 cm?
Schach [20]
Using lens equation;

1/o + 1/i = 1/f; where o = Object distance, i = image distance (normally negative), f = focal length (normally negative)

Substituting;

1/o + 1/-30 = 1/-43 => 1/o = -1/43 + 1/30 = 0.01 => o = 1/0.01 = 99.23 cm

Therefore, the object should be place 99.23 cm from the lens.

A cylinder has a magnetic flux of 13 Wb directed inward through its bottom end, and a magnetic flux of 22 Wb directed out of the
satela [25.4K]

To give a solution to this exercise, it is necessary to apply Gauss's magnetic law in which he proposes the magnetic flux through closed surface is zero.

Our data given are as follows:

Inward flux = 13Wb

Outward flux = 22Wb

Since the field of the second flow is directed OUT of the curved side we need to subtract the values, therefore,

Flux = 22-13

Flux = 9Wb\Rightarrow INWARD.

if it is true that the net charge in the universe does not change, how is it ever possible to charge an object that was initiall
olga55 [171]

By transferring electrical charges from one object to another

Explanation:

The law of conservation of electric charge states that the total electric charge of the universe is constant, therefore no charge can be created or destroyed, but only transferred.

Indeed, when an object is charged, this is due to the fact that charge carriers (typically electrons) are transferred to/from the object.

Consider an object initially neutral: this means that the object has initially an equal amount of positive charges (protons) and negative charges (electron).

Later, if we remove electrons from the object, then it will remain with an excess of protons: therefore, it will be positively charged. However, the electrons have not disappeared: simply, they have been moved somewhere else (on another object, for example, which will become negatively charged: so, the total net charge will still be zero).

Similarly, if we add electrons to the object, it will become negatively charged: however, the electrons have been removed from another object which is now positively charged, so the net charge still has not changed.

A rock at rest falls off a tall cliff and hits the valley below after 3.5s. What is the rocks velocity as it hits the ground
pogonyaev
T = 3.5 secs

Velocity (v) = g * t = 10 m/s^2 * 3.5 sec = 35 m/s
