When the mass of the cylinder increased by a factor of 3, from 1. 0 kg to 3. 0 kg, what happened to the cylindera's gravitational potential energy? It decreased by a factor of 3. It decreased by a factor of 2. It increased by a factor of 2. It increased by a factor of 3.

Answers

The mass of the cylinder increased by a factor of 3, the  gravitational potential energy increases by a factor of 3.

The given parameters:

Initial mass of the cylinder, m₁ = 1.0 kgFinal mass of the cylinder, m₂ = 3.0 kg

The gravitational potential energy of an object is calculated as follows;

P.E = mgh

where;

m is the mass

g is acceleration due to gravity

h is the height of the cylinder

when the mass = 1 kg

P.E = 1 x g x h

P.E = gh

when the mass = 3 kg

P.E = 3 x gh

P.E = 3gh

Thus, when the mass of the cylinder increased by a factor of 3, the  gravitational potential energy increases by a factor of 3.

Answers

During chemical reactions, bonds between atoms break and form Electrical fields of charged particles interact, bonding those with opposite charges.

What is the chemical bonds?

During chemical reactions, bonds between atoms break and form Electrical fields of charged particles interact, bonding those with opposite charges.

Since we know that every element have electrons in their atoms and every atom have vacant shells.

So during chemical reactions the elements fulfill their vacant shells and form bonds between each other it can be ionic or it can be covalent bond.

But when atoms breaks the bond their will be the positively or negatively charged electrons left in the atoms.

Hence During chemical reactions, bonds between atoms break and form Electrical fields of charged particles interact, bonding those with opposite charges.

Answers

Answer:

Explanation:

White dwarf, Sun, red supergiant shows the stars in the correct order, from smallest in size to largest.

What is the size stars?

More than 1.4 million kilometers span our Sun. However, not every star is the same size. They range in size from that of a metropolis to that of our solar system's half!

The mass of neutron stars is concentrated into a very compact area. Even though they are frequently only 20 to 40 km in diameter, they may hold the mass of one or two Suns. White dwarf stars are a little larger and frequently resemble the size of the Earth.

Compared to our Sun, the greatest supergiant stars can be more than 1500 times bigger. They are now more than 2,000 million kilometres across. Supergiants don't, however, have thousands of times the mass of the Sun. The reason for this is that as supergiants become older, their interiors become considerably more dispersed. Betelgeuse, a red giant in Orion's constellation, is nearly 1000 times broader than the Sun yet only has around 15 times as much mass.

At any point along the track, the rollercoaster's mechanical energy is equal to the sum of its potential and kinetic energies,

M = P + K

and we assume the coaster's total mechanical energy is conserved throughout its motion along the track, so that M is the same at every point.

At the first point,

K + 75,000 J = 90,000 J   ⇒   K = 15,000 J

At the second point, since M = 90,000 J everywhere,

K + 45,000 J = M   ⇒   K = 45,000 J

At the third point,

K + 0 J = M   ⇒   K = 90,000 J

The same principles apply to the pendulum, so M = 5,100 J throughout its swing.

At the first point,

K + 4,500 J = 5,100 J   ⇒   K = 600 J

At the second point,

K + 0 J = M   ⇒   K = 5,100 J

At the third point,

600 J + P = M   ⇒   P = 4,500 J

Answers

Hi there!

Recall that:

Change in momentum = mass × change in velocity

Or:

Δp = mΔv = m(vf - vi)

Plug in the given values. We can assign east to be positive and west to be negative in this instance (Velocity is a vector with direction).

Thus:

Δp = (1)(-21 - 10) = -31 kgm/s OR 31 kgm/s WEST.

The correct answer is B.

Change in momentum is EQUIVALENT to the quantity of IMPULSE.

The correct answer is H.

what is the static friction force and kinetic friction for the image

According to the plot, static friction force has a maximum magnitude of around 3.0 N, and kinetic friction has a magnitude of about 1.5 N.

The plot appears to be telling you the force required to get the yellow block moving along the table. If one applies less than 3.0 N of force, the block remains motionless. But as soon as it starts to slide, one need only apply 1.5 N of force to keep it moving (presumably at a constant speed).

what is momentum?
what is period of an oscillating body?
what is friction?

Answers

Answer:

Explanation:

Momentum is the quantity of motion of a moving body, measured as a product of its mass and velocity.

The period of an oscillating body is the smallest interval of time in which a system undergoing oscillation returns to the state it was in at a time arbitrarily chosen as the beginning of the oscillation.

Friction is a force between two surfaces that are sliding, or trying to slide, across each other.  Friction always slows a moving object down. The amount of friction depends on the materials from which the two surfaces are made. The rougher the surface, the more friction is produced.

Judging by the large number of medieval-themed books and movies, it's more popular than ever. Much like today, the characters in these medieval works all had clearly defined jobs or roles to play. Like today's occupations, these roles were all part of a process of career growth. For example, knights only became knights after a long, three-step process. If, at the age of seven, a boy displayed very good manners, smarts, and courage, his parents might decide they wanted him to become a knight. He would spend the next seven years as a page, performing simple duties such as helping knights with their horses and armor. After completing training as a page at around age 14, the boy would become a squire. A squire took on more responsibility and received more hands-on instruction in fighting and battle strategy. He would sometimes ride into battle with a knight and assist him. In some cases, the squire would even be required to fight in the knight's place if the knight was injured. At the age of 21, the squire was eligible to become a knight. First, he had to prove himself worthy by showing great bravery, wisdom, and devotion. worthy, he would be knighted in a ceremony where he vowed to protect his kingdom. Knights perform very different tasks from doctors, teachers, or professional athletes, but in each of these careers, there is a long process with clearly defined steps for moving up.
