What happens to the brightness of the bulb if the two resistors are exchanged? construct the correct explanation.

Answer:

Final velocity (v) = 36 m/s

Distance traveled (s) = 2,160 m

Explanation:

Given:

Initial velocity (u) = 0

Acceleration (a) = 0.3 m/s

Time travel (t) = 2 minutes = 120 seconds

Find:

Final velocity (v) = ?

Distance traveled (s) = ?

Computation:

v = u + at

v = 0 + 0.3(120)

v = 0.3(120)

v = 36 m/s

Final velocity (v) = 36 m/s

Distance traveled (s) = ut + (1/2)at²

Distance traveled (s) = (0.5)(0.3 × 120 × 120)

Distance traveled (s) = 2,160 m

The height of the image formed by the convex spherical mirror is approximately 0.64 cm.

To find the height of the image, we can use the mirror formula and magnification formula. The mirror formula is 1/f = 1/u + 1/v, where f is the focal length, u is the object distance, and v is the image distance. Using the given values, we can calculate v.

After finding v, we can use the magnification formula, M = -(v/u), to find the magnification (M). Finally, to find the height of the image (h'), we can multiply the object height (h) by the magnification: h' = M * h. In this case, h' = M * 2.0 cm, which gives us approximately 0.64 cm as the height of the image.

Almost 90% of the mass of spiral galaxies is in dark matter. So, option E.

Spiral galaxies make up around 77% of all the galaxies that have been spotted in the cosmos. A common spiral galaxy is our own Milky Way.

The rotational speed of the majority of spiral galaxies is directly proportional to mass in stars and gas that they are composed of. In these galaxies, the rotation speed is likewise influenced by the dark matter. However, because dark matter tends to be correlated with visible matter, rotational velocities are still correlated with visible mass.

Answer: the coefficient of friction

Explanation:

The magnitude of frictional force is \(\mu\)N and the magnitude of the force is N. So if we take the ratio of it we will get  \(\mu\) In result.

The friction coefficient is the ratio of the normal force pressing two surfaces together to the frictional force preventing motion between them. Typically, the Greek letter is used to symbolize it, i.e., \(\mu\). In mathematical terms, is equal to F/N, where F represents frictional force and N represents normal force. Since both F and N are measured in units of force, the coefficient of friction is a dimensional less quantity (such as newtons or pounds).

For both static and kinetic friction, the coefficient of friction has a range of values. When an object experiences static friction, the frictional force resists any applied force, causing the object to stay at rest until the static frictional force is removed. In kinetic friction, the frictional force resists the motion of the object.

if you drink lots of water while running your less likely to be hot and dehydrated. even if it's the same amount you run which tires your body and causes you to need more water.

It is hot and she is practicing more so she probably needs more water. The correct option is B.

When your body loses more fluid than you take in, you become dehydrated.

When your body's normal water content is reduced, it disrupts the balance of minerals (salts and sugar) in your body, affecting how it functions. Water accounts for more than two-thirds of the healthy human body.

As you lose fluid, your blood becomes more concentrated, requiring your cardiovascular system to work harder to pump blood efficiently. A high blood concentration causes your kidneys to retain more water, causing you to urinate less.

Dehydration occurs when you do not drink enough fluid or lose more fluid than you take in. The severity of dehydration is affected by a variety of factors, including climate, level of physical activity, and diet.

Thus, the correct option is B.

Answer:

Gravity is an ever present force, and therefore acceleration is guaranteed to happen at every single one of those points (and in fact, everywhere in the universe).

On top of that, friction will be present in all four spots (friction with the rails, with the air, with the axles, etc.), and friction is a perfectly acceptable force that will cause acceleration, slowing the roller coaster down.

So the correct answer is every single point, regardless of what answer the teacher expects.

The object will be moving faster if the acceleration and velocity are pointing in the same direction. The object will also slow down if the acceleration is pointing in the opposite direction as the velocity.

When an object's speed, direction of motion, or both change, it accelerates. Even while it may appear to be virtually immediate in some circumstances, such as when a golf ball is struck by a club or during car collisions, changes in an object's speed are always continuous.

Since gravity is a constant force, acceleration will unavoidably occur at each of those locations and throughout the whole universe.

Therefore, In addition, there will be friction at all four locations—friction with the axles, the air, the rails, etc.—and friction is a completely normal force that will accelerate the roller coaster, slowing it down.

Due to the greater disorder of molecules and the increase in heat energy associated with the liquid state, 1 kg of liquid iron would have greater entropy compared to 1 kg of solid iron.

The kilogram of liquid iron would have greater entropy compared to the kilogram of solid iron. Entropy is a measure of the disorder or randomness in a system.

In the case of iron, when it transitions from a solid to a liquid state, the arrangement of its molecules becomes more disordered.

In the solid state, the iron atoms are arranged in a regular lattice structure, which is more ordered compared to the random arrangement of molecules in the liquid state. The increased disorder in the liquid state contributes to higher entropy.

Additionally, as you mentioned, in order to transform solid iron into liquid iron, heat is added. This increase in heat energy also contributes to higher entropy since it leads to greater molecular motion and randomness within the system.

Therefore, due to the greater disorder of molecules and the increase in heat energy associated with the liquid state, 1 kg of liquid iron would have greater entropy compared to 1 kg of solid iron.
