WILL GIVE BRAINLIEST TO THE BEST Scenario

Espresso Coffee House is designing a coffee mug that keeps liquids hot. The research department tested several different materials for their ability to keep a normal-sized cup of coffee hot the longest amount of time. The testing room temperature is approximately 25 degrees Celsius.

Prompt

Write a scientific explanation to justify the selection of material, A, B, or C, used to create the cup that would keep the coffee the hottest for the longest period of time.

Write a scientific explanation to justify the selection of material, A, B, or C, used to create the cup that would keep the coffee the hottest for the longest period of time.

CLAIM

Write a 1-sentence statement that responds to the prompt.

first let us lay out the formula for potential

and kinetic energy:

pe = mgh

ke = (mv^2)/2

where: m=mass, v=velocity, g=gravitational

acceleration, h=height

calculating for mass using the known values of

pe:

340j = m (9.81 m/s^2) (50ft) (1m/3.28ft)

m = 2.27 kg

the law of conservation of energy states that

energy is neither created nor destroyed. therefore, the change in kinetic

energy from 50 ft to 35 ft would be equal to the change in potential energy

from 50 ft to 35 ft. however it would be opposite in signs since one is losing

while other is gaining.

ke(35ft) – ke(50ft) = - [ pe(35ft) – pe(50ft]

ke(50ft) = 0 since the brick is initially at rest

ke(35ft) = 340j - 2.27kg (9.81 m/s^2) (35ft)

(1m/3.28 ft)

ke(35ft)

= 102.38 j

the maximum mass of nh3 is nh3 in grams

(b) which contains higher levels of vitamin b, oranges or spinach?

explanation:

you can eliminate a, c, and d because they are questions based on opinions.
