Radiometric dating: Radiometric dating is a method of determining the age of materials by measuring the decay of radioactive isotopes. The most common radioactive isotopes used for radiometric dating are uranium-238, potassium-40, and rubidium-87.

These isotopes decay at a known rate, and by measuring the amount of radioactive material and its decay products, scientists can calculate the age of the material.

Meteorites: Meteorites are pieces of rock that have fallen to Earth from space. They are thought to be remnants of the solar system's formation, and they can be used to date the solar system.

By measuring the composition of meteorites and comparing them to the composition of the Sun and planets, scientists can estimate the age of the solar system.

Moon rocks: The Moon is thought to have formed from a collision between the Earth and a Mars-sized object early in the solar system's history.

By studying the composition of Moon rocks, scientists can learn about the conditions that existed in the solar system at the time of the collision. This information can be used to estimate the age of the solar system.

The age of the solar system is a fundamental piece of information about our planet and its place in the universe. By understanding the age of the solar system, we can better understand how it formed and evolved. This knowledge can help us to understand the future of our planet and its place in the universe.

The velocity of the body is 16.1 m/s.

The rate of motion and direction of an object are measured by a vector known as velocity. Therefore, we need to understand both the magnitude and direction in order to calculate the velocity according to this definition.

For instance, if an object moves at 5 meters per second (m/s) in the direction of the west, its velocity in that direction will be 5 m/s. The most popular and straightforward method for calculating velocity is given in the formula below.

While m/s (meter per second) is the SI unit for velocity, it can also be expressed in any d/t unit (distance per time). Miles per hour (mph), kilometres per second (km/s), and kilometers per hour are a few of the units that can be used to express velocity (kph).

D. the water's latent heat of vaporization is being pulled from the air.

Explanation:

A swamp cooler also generally referred to as the evaporative cooler is an electronic device that uses moisture to cool air. This simply means that, the electronic device works on the principle of evaporation of water to cool the surrounding air.

In swamp coolers, water absorbs large amount of warm air via the evaporative wet cooler pad, so as to evaporate and consequently cooling the air effectively and efficiently.

Swamp coolers are effective because the water's latent heat of vaporization is being pulled from the air.

The latent heat of vaporization can be defined as the energy that is being absorbed by water during evaporation.

The swamp coolers are typically made up of the following essential components, these are;

1. Float.

2. Blower.

True, one of the eight steps to establish and verify an electrically safe work condition is to release stored energy.

Releasing stored energy is a critical step in ensuring electrical safety during maintenance or repair work. When working on electrical equipment, there can be residual energy stored in capacitors, inductors, batteries, or other sources.

This stored energy poses a significant risk to workers if not properly released before beginning work. To mitigate this risk, the process of releasing stored energy involves discharging capacitors, removing power sources, and ensuring that all energy sources are de-energized. It may also involve following specific procedures provided by equipment manufacturers or industry standards.

By releasing stored energy, potential hazards such as electric shock, arc flashes, or explosions can be minimized, creating a safer work environment for electrical workers.

The average change in momentum for the car during the trip is 8400 kg·m/s.

What is Momentum?

Momentum is a vector quantity, meaning it has both magnitude and direction. The direction of momentum is the same as the direction of velocity, and its magnitude is proportional to both the mass and the velocity of the object.

Then, we calculate the final momentum of the car during the remaining 3 hours:

Final momentum during the remaining 3 hours = mass × final velocity during the remaining 3 hours = m × v2

Now, we can calculate the average change in momentum:

Average change in momentum = Final momentum - Initial momentum

= (Final momentum during the first 2 hours + Final momentum during the remaining 3 hours) - Initial momentum

= [(m × v2) + (m × v2)] - (m × v1)

= 2m × v2 - m × v1

Plugging in the given values:

Mass of the car (m) = 1400 kg

Initial velocity (v1) = 32 m/s

Final velocity during the first 2 hours (v2) = 38 m/s

Average change in momentum = 2m × v2 - m × v1

= 2 × 1400 kg × 38 m/s - 1400 kg × 32 m/s

= 53200 kg·m/s - 44800 kg·m/s
