eased to 10°C. (Round your jonathanlewisforcongress.coms to two decimal places.) (a) What is the temperature of the drink after 45 minutes? °C (b) When will its temperature be 16°C? min
b) t=83.38 min
After 25 min, T=10°C
We know that cold drink will cool because its surrounding temperature is high .
You are watching: When a cold drink is taken from a refrigerator
From Newton”s law of cooling
Where K is the constant,T is the temperature at any time t and
is the surrounding temperature.
By solving above differential equation
When t=25 min T=10°C
(a) When t=45 min
(b) When T=16°C
How is the mechanical efficiency of a machine usually expressed 1. As a fraction 2. As a percentage 3. As inches or feet 4. As o
The efficiency of any contraption that uses energy to do a job is defined as (amount of useful energy output) / (amount of energy input) .In describing or talking about the efficiency f the machine, it”s most often expressed as a percentage. It”s important to notice that the output is taken to be the useful output.Why is that important ? Here”s a simple example:If you use an incandescent light bulb as a source of light, then the useful output is the light, and its efficiency is quite low.If you use an incandescent light bulb as a source of heat, thenthe useful output is the heat, and its efficiency is quite high.
During the stage of internal combustion engine operation in which the piston rises and compresses the fuel in the combustion cha
The piston rises and compresses the fuel in the cylinder during the “compression” stroke. Both valves have to closed in order to compress the fuel in there. If either valve were open, just a crack, then the gases wouldn”t get as compressed as they should … they”d just get forced out into the fuel line or the exhaust line through the open valve.
Oceania crust is typically made up of igneous rocks such as basalt. Igneous rocks are formed when lava flows from volcanoes cool and harden.
Entrepreneurs are not wild risk takers but are instead calculating risk takers. They appear to be risk takers because they see the market differently than the rest of us do. 3. … Entrepreneurs tend to be optimistic about their chances for success, and usually their optimism is based in reality.
