If you drop a 50 gram piece of metal that has a temperature of 110°Celsius into 1000 grams of water at 25°Celsius, what best describes what would occur?A.) The water will quickly reach the boiling point.
B.) The water’s temperature will stay the same, but the metal will cool down.
C.) The water’s temperature will increase, and the metal will stay constant.
D.)The water and the metal’s temperature will reach the same temperature.

Answers

If you drop a 50 gram piece of metal that has a temperature of 110°Celsius into 1000 grams of water at 25°Celsius, D.)The water and the metal’s temperature will reach the same temperature. In any system undergoing heat transfer, the objects involved will eventually reach the same temperature, signifying thermal equilibrium.

Answer:

D.)The water and the metal’s temperature will reach the same temperature.

Explanation:

As we know that heat is a dynamic energy which will flow from high temperature to low temperature.

So here we know that 50 g metal piece at 110 degree Celsius is dropped into the water at 25 degree Celsius. Since metal is at higher temperature so here the heat will flow from metal to the water and this will continue till the temperature of these two bodies will become equal.

So here the final temperature of metal and the water will be same at thermal equilibrium.

So here correct answer will be

D.)The water and the metal’s temperature will reach the same temperature.

What type of machine is a pair of scissors?a. Simple - Lever

How could i design an experiment to test the speed of sound in different materials such as fabric, cardboard, steel, aluminum, plastic.

Answers

To design an experiment to test the speed of sound in different materials, you could use a speaker and a microphone to measure the time it takes for sound to travel through each material. First, you would need to set up the speaker and microphone on opposite sides of each material and measure the distance between them. Then, you would play a sound from the speaker and measure the time it takes for the sound to reach the microphone. You could repeat this process for each material and use the data to calculate the speed of sound in each material. Additionally, you could compare your results to the known speed of sound in air (343 m/s) to see how the materials affect the speed of sound.

Number 33 apparently the answer is 4 but I have no idea why

Answers

It would help if you managed to capture the whole question and all the answer choices
in the picture. Fortunately, you caught the whole question in the picture of #32.

Tools you need in order to answer this one:
-- When the frequency of a wave goes up, the wavelength gets shorter. 
(That's why the high numbers on a radio receiver are called 'short-wave'.)
-- Photons with higher frequency carry more energy.
(That's why x-rays and gamma rays are dangerous to our delicate human tissues.)

Do you remember hearing these things in class ?

Anyway, as the frequency of the photons increases,  their
energy increases, and their wavelengths get shorter.

I hope that's one of the choices that escaped getting caught in the photo.

Why does a year consist of 365 days and a day of 24 hours?

Answers

For question 1: What percentage of the earth is covered by water?

Your answer for question 1: About 71 percent of the earth's surface is covered by water.

For Question 2: Did dinosaurs and humans ever exist at the same time?

Your answer for question 2: No. Dinosaurs went extinct at the end of theCretaceous period, 65 million years ago. Modern humans did not appearuntil around 200,000 years ago.

For question 3: What is Darwin's theory of the origin of species?

Your answer for question 3: Darwin's theory of species origination says thatnatural selection chooses organisms that possess variable and heritabletraits and that are best suited for their environments.

For question 4: Why is the sky blue?

Your answer for question 4:
Solar radiation sunlight is scattered across theatmosphere by a process called diffused sky radiation. The sky is bluebecause much more short-wave radiation, blue light, is scatteredacross the sky than long-wave radiation, red light.

For question 5: What causes a rainbow?

Your answer for question 5: Rainbows can be seen when there are water droplets in theair and the sun is shining. Sunlight, which contains all colors, isrefracted, or bent, off the droplets at different angles, splittinginto its different colors of red, orange, yellow, green, blue, indigoand violet.

For question 6: Why does a year consist of 365 days and a day of 24 hours?

Your answer for question 6: A year, 365 days, is the time it takes for the Earth totravel around the Sun. A day, 24 hours, is the time it takes for theEarth to spin around once on its axis.
