When the motion energy of an object changes, there is inevitably some other change in energy at the same time. If an object is slowing down, where is the energy going? (Check all that apply)

Question 9 options:

The potential energy could be increasing, like a ball thrown into the air.


The kinetic energy could be lost to friction or air resistance.


The ball could be returning to its natural resting state.


Due to the conservation of energy, the kinetic energy must stay the same.

Answers

Answer 1

Explanation:

This problem bothers on the conservation of mechanical energy

This is the principles in which the energy changes by virtue of the position of the body and when in motion are conserved.

The principle of conservation of mechanical energy  states that "energy can neither be created nor destroyed but can be transformed from one form to another".

Based on the principle of energy conservation the correct options are

The potential energy could be increasing, like a ball thrown into the air.The kinetic energy could be lost to friction or air resistance.The ball could be returning to its natural resting state.

An object has an acceleration of 18.0 m/s/s. If the net force was doubled and the mass were tripled then the new acceleration would be

Answers

Answer:

12.0 m/s²

Explanation:

Newton's second law:

F = ma

Solving for acceleration:

a = F/m

If force is doubled and mass is tripled:

a' = (2F)/(3m)

a' = ⅔ (F/m)

a' = ⅔ (18.0 m/s²)

a' = 12.0 m/s²

The new value of acceleration of object is 12 m/s².

Given data:

The magnitude of acceleration of object is, [tex]a =18 \;\rm m/s^{2}[/tex].

Let F be initial net force and m be the initial mass. Then as per the problem, the new values of each are,

F' = 2F

m' = 3m

Apply the Newton's Second law, which says that the product of mass and acceleration of object given net force. Then,

F = ma

F = m(18)

F/m = 18 .................................................(1)

Now, for new value of net force,

F' = m'a'

2F = (3m) a'

2F/3m = a'

a' =2/3× (18)                                                   (From equation 1)

a' = 12 m/s²

Thus, we can conclude that the new value of acceleration of object is 12 m/s².

B. Individuals pass on their best traits to their offspring.

C. Mutations help an individual survive and reproduce.

D. Well-adapted individuals survive and reproduce.

Answers

Answer:

B. Individuals pass on their best traits to their offspring.

Explanation:

because genes are always passed from parents to offspring.

The best summary of the process of natural selection is Individuals pass on their best traits to their offspring. Hence, the correct option is B.

What is the theory of Natural selection?

The theory of natural selection gives the mechanism of evolution. It defines the method of different survival and reproduction of individuals due to differences in phenotype.

The theory of natural selection was proposed by Charles Darwin as a way of adaptation and speciation. The variations occur in organisms by random mutations occurring in the genome of individual organisms and this change in mutations may inherit in offspring.

Organisms that are more adapted to the environment are more likely to survive and pass on the genes to future generations. This process cause changes to the generations and diverged over time.

The organisms produce more offspring that are able to survive in the environment. The four factors of natural selection are Variations, Inheritance, Selection, and time.

Thus, the best summary of the process of natural selection is individuals pass on their best traits to their offspring. Hence, the ideal solution is option B.

How much current must be applied across a 60 Ω light bulb filament in order for it to consume 55 W of power? Unserious answers will be deleted, and reported. (Please show some work)

Answers

Answer: current I = 0.96 Ampere

Explanation:

Given that the

Resistance R = 60 Ω 

Power = 55 W

Power is the product of current and voltage. That is

P = IV ...... (1)

But voltage V = IR. From ohms law.

Substitutes V in equation (1) power is now

P = I^2R

Substitute the above parameters into the formula to get current I

55 = 60 × I^2

Make I^2 the subject of formula

I^2 = 55/60

I^2 = 0.92

I = sqr(0.92)

I = 0.957 A

Therefore, 0.96 A current must be applied.

Answer:

acceleration

Explanation:

From the question: "FORCE... divided by the MASS..." is translated to a math equation as "F / m", where "F" is the force and "m" is the mass.  

Now, the second Newton's law says "F = m . a ", where a is acceleration.

If you move m to the left side, clearly you have "F / m", and "a" is alone to the right. Math equation:

a = F / m

What is an intermolecular force in matter?

An intermolecular force is a force of attraction or repulsion that exists between molecules or atoms within a substance.

Here,
In the gaseous state, the intermolecular forces are weak, and the molecules are far apart and move freely in all directions. In the liquid state, the intermolecular forces are stronger, and the molecules are closer together, but still able to move past each other. In the solid state, the intermolecular forces are the strongest, and the molecules are tightly packed together in a fixed arrangement, which results in a definite shape and volume.

Therefore, the correct order of increasing the intermolecular force of attraction for the three most common states of matter is gas, liquid, and solid.

A tennis ball and a solid steel ball of the same diameter are dropped at the same time. Which ball has the greater amount of force acting on it?

Answers

The steel one.

The steel one has more force due to the weight and mass.

An object's mass is a crucial indicator of how much stuff it contains. The gravitational pull of an object is measured by its weight. It is influenced by the object's location in addition to its mass. As a result, weight is a measurement of force.

What ball has the greater amount of force acting on it?

The heavier (denser) object will fall quicker if two identically sized but made of different materials objects are present. This is because both objects will experience the same drag and buoyancy forces, but the heavier object will experience a stronger gravitational pull.

Things fall to the earth faster as a result of gravity. Acceleration is a modification of velocity, and velocity is a measurement of the direction and speed of motion. The longer an object is in free fall, the faster gravity makes it tumble toward the ground.

Therefore, solid steel ball have high mass and greater amount of force acting on it.

Producing 100 L of ethanol from sugar cane
Producing 200 L of ethanol from sugar beet
Producing 300 L of ethanol from potatoes
Producing 400 L of ethanol from corn

Answers

Answer:

Producing 300 L of ethanol from potatoes

Explanation:

From the diagram, one liter of ethanol production from sugar cane requires 2000 liters of water. Hence, in order to produce 100 L of ethanol from sugar cane, 2000 x 100 = 200,000 L of water.

1000 liters of water is needed to produce 1 liter of ethanol from sugar beet. Hence, 200 x 1000 = 200,000 L of water will be needed to produce 200 liters of ethanol.

1000 liters of water is also required to produce 1 liter of ethanol from potatoes, hence, 300 x 1000 = 300,000 L of water would be required to produce 300 L of ethanol from the same material

About 500 liters of water is required to produce 1 liter of ethanol from corn, hence, 400 x 500 = 200,000 L of water would be needed to produce 400 L of ethanol from corn.

In conclusion, producing 300 L of ethanol from potatoes would require using the most water among all the options.

What is the net force acting on a .15 kg hockey puck accelerating at a rate of 12 m/s2

Answers

Answer:

The net force is 1.8N

Explanation:

Given that the formula for force is Force = mass×acceleration. So you have to substitute the values into the formula :

[tex]force = mass \times acceleration[/tex]

Let mass = 0.15kg,

Let acceleration = 12m/s²,

[tex]force = 0.15 \times 12[/tex]

[tex]force = 1.8[/tex]

Answer:

1.8 Newtons

Explanation:

We want to figure out the net force acting on a 0.15 kg hockey puck that has an acceleration of 12 m/s². To solve this, we must apply Newton's Second Law of Motion which is denoted by the formula: f = ma.

Here, f is the force, m is the mass, and a is the acceleration. Plug our given values in to find f:

f = ma

f = (0.15 kg) * (12 m/s²) = 1.8 Newtons

Thus, the answer is 1.8 N.
