Why do our eyes see the color red when we look at a tomato?
A. Tomatoes emit red light.
B.Tomatoes reflect red light and absorb green and blue light.
C. Tomatoes absorb red light and reflect green and blue light.
D. Tomatoes reflect all colors of light, but our eyes only absorb red light,
Answer:
B. Tomatos reflect red light
Explanation:
The only reason colors exist is because the objects with color reflect all other light except for what they are portrayed as. White reflects all colors, and black absorbs all colors.
If you have any questions feel free to ask :)
Answer:
Explanation: the pigment atoms in the skin absorb photons of all energies except those that correspond to red wavelengths of light, which they reflect back to your eye.
B is more likely the answer

Geologists use tools other than the law of superposition to help them with relative dating. Which statements describe those tools? Check all that apply.
Answer: Cross-cutting features are always younger than the surrounding rock.
When material erodes before sediment is deposited on it, a geologic gap results.
Explanation:
The options include:
1. An unconformity is created when lava pours out on Earth’s surface.
2. Faults are the result of volcanic activity.
3. Intrusions and extrusions are sedimentary formations.
4. Cross-cutting features are always younger than the surrounding rock.
5. When material erodes before sediment is deposited on it, a geologic gap results.
The law of superposition simply states that when there is a layers of rocks, we would see that the younger layers will lie and be on top of the layers that are older.
Other tools that can help scientist with relative dating are:
• Cross-cutting features are always younger than the surrounding rock.
• When material erodes before sediment is deposited on it, a geologic gap results.

Answer:
68.6N
Explanation:
Given parameters:
Mass of object = 7kg
Unknown:
Weight = ?
Solution:

what is the approximate increase in thermal energy in joules when the temperature of 15 grams of water is raised from 20° to 35° C. the specific heat of water is 4.19 j/g degrees Celsius
Answer:
942.75J
Explanation:
Change in thermal energy is equal to the mass of the given substance times the specific heat capacity times the temperature change.
We've already been given the specific heat capacity, the mass as well as the initial and final temperatures.
So change in temperature will be 35° - 20° = 15°
Thermal energy change = 15 × 15 × 4.19
The final answer is 942.75J
Hope that helped.
The half-life of radium-226 is 1600 years. How many
grams of a 7 g sample will remain after 3200 years?
SHOWALL STEPS TO SOLVE THE PROBLEM
Answer:
1600 years half life
3200/1600 is 2 half lifes
first half life takes the sample to 1/2 it's original amount and the second takes it to 1/4 of it's original amount
so 1/4*7gm is 1.75gm

A group of friends are going bowling. They discuss how ball weight and speed can change the amount of
kinetic energy transferred to the pins.
They can use a 6 pound, 10 pound or 12 pound ball.
They can roll the ball at 10 miles per hour (beginner), 14 miles per hour (intermediate) or 18 miles per hour (professional) speed.
A. Describe a strategy that they could use to transfer the greatest amount of kinetic energy to the pins.
B. Explain the relationship between kinetic energy and strategy that you chose in part A.
C. Draw a model that demonstrates the energy transfers that occurred in the system.
Answer:
A. you would want to use the 12 ound ball and the 18 mph speed in order to transfer the most kinetic energy
B. KE= 1/2 MV^2 so you would want to maximize both your Mass(weight of the ball) and Velocity(speed of the roll) in order to achive the greatest KE.
C. see image
Explanation:
Full disclosure not totally sure what you are being asked in the last one but I put togethere a rough sketch that is my best guess.

Discuss the characteristics of cool red dwarf stars, including their mass and age.
Discuss the correlation or connection between stars with a higher mass and the amount of fuel they have to work with.
How old is the sun and since its birth, how has the sun changed?
During its lifespan, what characteristics of the sun will change?
Answer:
(3rd Question about the Black Widow Pulsar)
J1311 is a fast spinning neutron star, which means it emits strong beams of radiation from it's poles.
As the beam of the pulsar sweeps across the surface of the companion star, it heats it up and blows its material outward into space, thus decreasing its mass.
A 1-kg plastic block is neutrally buoyant when submerged in water with a density of 1 g/cm3. If the same block is placed, such that it is completely submerged, in a container of oil with a density of 0.8 g/cm3, find the acceleration of the block.
Answer:
-2 m/s
Explanation:
The computation of the acceleration of the block is as follows:
The volume of the block is
V = 1kg ÷ 1,000 kg/m^3 = 1 ÷ 1,000 m^3
Now at the time of submerging in the oil
Net force is
[tex]m_g - F_B = m \times (-a)\\\\m_g - v\times S_{oil} \times g = -ma\\\\a = (\frac{v}{m} \times S_{oil} - 1) g\\\\= (\frac{1}{1000} \times 0.8 \times 1000 -1 ) \times 10\\\\[/tex]
= -2 m/s

4. A force of 6.0 Newtons is applied to a block at rest on a horizontal frictionless surface over a 7.0 meter span. How much energy is gained by the block?
Answer:
42 Joules
Explanation:
Given that a force of 6.0 Newtons is applied to a block at rest on a horizontal frictionless surface over a 7.0 meter span. How much energy is gained by the block?
The parameters given are:
Distance covered = 7.0 m
The force = 6.0 m
The formula for work done is the product of force and distance. That is,
Work done = force × distance
Where work done is the same as energy.
Energy = force × distance
Energy = 6 × 7
Energy = 42 Joules.
Therefore, the energy gained by the block is 42 Joules.
