Explain how potential and/or kinetic energy are working in each of the pictures below

Answers

Answer: canetic carts

Explanation:

In the first one, kinetic energy got the roller coaster to the top of the hill, and it becomes lots of potential energy due to being at the top of a steep drop.

In the second one, it begins with potential energy, until the person is put into a falling motion, transferring to kinetic energy.

In the third one, there is potential energy, because the bow string is taut, and ready to release and allow the arrow to go flying.

In the fourth one, the car has gas which is potential energy, until it begins moving and is turned into kinetic energy.

Describe at least one way that builders can mitigate the impact of human activity on Earth's water

Answers

Builders must keep streets and sidewalks near their project clean to reduce harmful runoff discharge. They should also collect and treat water waste produced while working. Construction companies can even treat and repurpose their water waste to minimize pollution

Answer:

Builders can minimize their water pollution and maximize their sustainability by following environmental guidelines set by their federal and local governments and by adopting more environmentally sound practices of their own volition.

Explanation:

Many nations have issued sweeping regulations to preserve clean water.

In the United States, for example, the Clean Water Act places special attention on construction activity where disposal sites may interfere with water and wildlife.

In the EU, the Water Framework Directive requires each state to set objectives related to water standards, monitoring sewage, agricultural use and waste among other concerns.

Answers

Answer:

vulnerable to :)

Explanation:

A penicillin-resistant parent bacteria cell's subsequent generations of bacteria from this parent will be resistant to penicillin. The third option is correct regarding the antibiotics.

What is antibiotic resistance?

The antibiotics are given to kill the bacteria and remove the bacterial infection from the body, but when the bacteria come into contact with the antibiotics for a long time, they will become resistant to them. This is called "antibiotic resistance," as neither the antibiotics nor the bacteria can harm each other now.

Antibiotic resistance is harmful to humans because it necessitates a high dose of antibiotics when infections occurs. This drug has many side effects and can harm the body as well. When the bacteria become resistant to the antibiotic penicillin, all the next generations will be resistant to the antibiotics.

As a result, the correct answer is the third option, which states that future generations will be resistant to penicillin.

Explanation:

When the speed of the bottle is 2 m/s, the KE is kg m2/s2. When the speed of the bottle is 3 m/s, the KE is kg m2/s2. When the speed of the bottle is 4 m/s, the KE is kg m2/s2. When the speed of the bottle is 5 m/s, the KE is kg m2/s2. When the speed of the bottle is 6 m/s, the KE is kg m2/s2.
instructions
In this part of the experiment, you will be changing the speed of the bottle by dropping it from different heights. You will use the same mass, 0.250 kg, for each trial, so record this mass in Table B for each velocity. Then, calculate the expected kinetic energy (KE) at each velocity. Use the formula KE = mv2,
where m is the mass and v is the speed. Record your calculations in Table B of your Student Guide.

Answers

Answer:

Based on the given instructions, you need to calculate the expected kinetic energy (KE) at each velocity using the formula KE = mv^2, where m is the mass and v is the speed. The mass is given as 0.250 kg.

Table B: Calculation of Kinetic Energy (KE)

Speed (m/s)Mass (kg)KE (kg m^2/s^2)20.2500.50030.2500.75040.2501.00050.2501.25060.2501.500

To calculate the kinetic energy at each velocity, multiply the mass (0.250 kg) by the square of the velocity.

For example, when the speed of the bottle is 2 m/s: KE = (0.250 kg) * (2 m/s)^2 = 0.250 kg * 4 m^2/s^2 = 1.000 kg m^2/s^2

Perform similar calculations for the other velocities and record the results in Table B.

Answer:

Explanation:mass of the bottle in each case is M = 0.250 kg

now as per given speeds we can use the formula of kinetic energy to find it

1) when speed is 2 m/s
