What causes the apparent colors of the objects we see?
Answer: The human eye and brain transform light into color. Allowing us to see them.
Explanation: Light receptors within the eye turn light into color. The color that is reflected off of an object, is what we see. Hope this helps.
The apparent colors of the objects we see causes due to reflection of the light which they absorb and emit.
What is reflection?Reflection is the change in direction of a wavefront which occurs at an interface present between the two different media so that the wavefront of the wave returns into the medium from which it has been originated. Common examples of reflection include the reflection of light, sound wave and water waves.
The color of an object is the wavelengths of light waves that it reflects. The reflection is determined by the arrangement of electrons in the atoms of that substance which will absorb and re-emit photons of particular energy levels according to the quantum laws.

In many areas electricity is produced by huge generators close to dames. What function does a large volume of moving water have in generating electricity?
Answer:
To increase the volume of moving water, impoundments or dams are used to collect the water. An opening in the dam uses gravity to drop water down a pipe called a penstock. The moving water causes the turbine to spin, which causes magnets inside a generator to rotate and create electricity.
What question can a student BEST answer when comparing and contrasting the models?
Answer:
A
Explanation:
What is the acceleration of a 5.9 kilogram bowling ball if a force of 11 N is applied to it?
Answer:
1.86 [tex]m/s^{2}[/tex]
Explanation:
Acceleration = [tex]\frac{Force}{mass}[/tex]
Force = 11N
Mass = 5.9 kg
∴ Acceleration = [tex]\frac{11}{5.9}[/tex]
= 1.86 [tex]m/s^{2}[/tex]

when is the object at rest? in constant speed? accelerating?
Answer:
Answered in explanaion.
Explanation:
REST: When an object does not change its position with respect to its frame of reference or surrounding, then the object is said to be in the state of rest.
CONSTANT SPEED: When the object covers equal distance in equal intervals of time, the object is said to be moving with constant speed.
ACCELERATING: An object is said to be accelerating when the speed of the object increases with respect to time.

what would be the mass of a rock falling from the sky if it hits the ground with a force of 147 N
Explanation:
we know,
F = mg
where m is mass of object and g = acc. due to gravity (9.8 ) m/ s^2
147 = m x 9.8
147/ 9.8 = m
15 = m
therefore mass of object = 15 kg

If a riding lawnmower engine exerts 19 hp in one minute to move the mower, how much work is done? (Hint convert: 1 watt equals 0.00135962 hp)
Answer:
Work done = 838470 Joules.
Explanation:
Given the following data;
Power = 19 hp
Time = 1 minute to seconds = 60 seconds.
Next, we would convert the unit of power in "hp" to "Watt."
1 Watt = 0.00135962 horsepower
x Watt = 19 horsepower
Cross-multiplying, we have;
19 = 0.00135962x
x = 19/0.00135962
x = 13974.5 Watts.
Now, to find the work done in moving the mower;
Work done = power * time
Substituting into the formula, we have;
Work done = 13974.5 * 60
Work done = 838470 Joules.

Answer:
I think it's 250
Explanation:
If the car is traveling 50 km/hr that means every hour, the car drives 50 km. So if you want to know how far it will go in 5 hours you do 50x5.
