Which statement would be the best evidence that heat transfer through radiation has occurred and why? A) A pan gets hot on a sto

ve. Radiation requires molecule to molecule contact. B) On a windy day, you feel colder. This is because more heat is removed from your body. C) At several feet from a fire, you still feel the heat. Heat is transferred through the air. D) An oven uses fans to heat up the food inside faster. Radiation is the most efficient form of heat transfer.

a 202 kg bumper car moving right at 8.50 m/s collides with a 355 kg car at rest. Find the total momentum of the system.
Hunter-Best [27]

Explanation:It is given that,

Mass of bumper car, m₁ = 202 kg

Initial speed of the bumper car, u₁ = 8.5 m/s

Mass of the other car, m₂ = 355 kg

Initial velocity of the other car is 0 as it at rest, u₂ = 0

Final velocity of the other car after collision, v₂ = 5.8 m/s

Let p₁ is momentum of of 202 kg car, p₁ = m₁v₁

Using the conservation of linear momentum as :

p₁ = m₁v₁ = -342 kg-m/s

So, the momentum of the 202 kg car afterwards is 342 kg-m/s. Hence, this is the required solution.

Newton’s ideas on physics “won”, and aristotle’s ideas were kicked out of science and over into history. why?
mestny [16]
Basically, Newton's ideas matched up better with experiments and observations about the natural world than Aristotle's did. Newton gave a rigorous mathematical framework that made very specific predictions about our world, while Aristotle in general made more comparative laws, that even when true were less useful than the certainty Newton's laws gave us. Many of Newton's laws have been found to be at least partially incorrect now, for instance his laws of motion fall apart at speed nearing the speed of light, his laws of gravity fall apart when talking about more than two objects and in the presence of large gravitational fields that are close together, and Newton's law of cooling is just untrue in general (though can make some approximations in narrow temperature ranges).

Identify the differences between the dfss (design for six sigma) and the dmaic (define, measure, analyze, improve, control) proc
s344n2d4d5 [400]

The difference between the dfss (design for six sigma) and the dmaic (define, measure, analyze, improve, control) processes only lies in the analyzing stage. To further avert problems, DFSS requires market research data, customer complaints about the product, and attempts to rebuild a new product.

The primary distinction is that DMAIC is a technique that emphasizes making changes to the organization's current goods and services.

On the other hand, DFSS strives to create a new, defect-free good or service that satisfies CTQ requirements and results in customer satisfaction.

Design for Six Sigma (DFSS) is an improvement process that aids companies in producing high-quality new goods and services.

The technique tries to satisfy client expectations while making the most of the company's capabilities during the initial development of a process.

A data-driven quality technique called Define, Measure, Analyze, Improve, and Control (DMAIC) is used to enhance processes.
