Answer:
Throughout the description box below, the overview including its query is listed.
Explanation:
- Hypothesis: unless the food is colored, then it would be picked by the youngsters or kids.
- Independent Variable: The Hue Variable or color.
- Dependent variable: The proportion of children selecting the potatoes selected.
- Controlled variables: The community of plans.
- Control procedure or treatment: The color selection community.
INFORMATION:
Is given that:
- if you have a block of plastic and a block of copper that are the same mass and are placed in the sun for 10 minutes.
And after the 10 minutes copper has a higher temperature.
We must determine the reason.
STEP BY STEP EXPLANATION:
To determine it, we need to know the concept of specific heat
If the block of copper has a higher temperature after 10 minutes, that means copper needs less heat to raise its temperature.
So, plastic has a higher specific heat than metal, so it takes more energy to heat plastic than copper. As a result, plastic would heat up more slowly.
ANSWER:
The explanation for the copper having a higher temperature after 10 minutes in the sun, is that plastic has a higher specific heat than metal, so it takes more energy to heat plastic than copper. As a result, plastic would heat up more slowly. Since the copper has a lower specific heat, it will be heat quickly.
Answer:Set up a proportion os V1/n1 = V2/n2. V is the volume, n is the amount in MOLES, not grams. Convert the CO_2 to moles, then solve and find that the amount of N_2 should be the same amount of moles. Then use the molar mass of N_2 (28.02 grams/mole) to convert that amount of moles into grams. That's your answer.
Explanation:
We know, Weight = Mass * Gravity
Here, Mass = 20 Kg
Gravity = 10 m/s² [Approximate value ]
Substitute their values,
w = 20 * 10
w = 200 N
In short, Your Answer would be Option C
Hope this helps!
