27) The connections between neurons in the retina, specifically the connections referred to as “lateral inhibition,” help us see which of the following better?
Contrast
Faces
Colors

45) Improving the contrast of an image (making the dark regions darker and the light regions lighter) helps us to identify:

The edges of objects
The center of objects
The color of an object

67What assumption does our visual system make in order to see curved surfaces (domes, holes)?

Light comes from above
Curved surfaces are always evenly lit
Curved surfaces are always easy to see, no assumptions are made

78) Which part of the face does our brain pay the most attention to?

Eyes and mouth
Eyes and ears
Eyes and chin

88) If all these assumptions sometimes lead to mistakes, for example in these optical illusions, why do we make them?

It helps us see things faster
It helps us see things correctly
It helps us pay attention to what's important
All of the above

Help?? How does the thermal energy of a swimming pool compare to the thermal energy of a lake at the same temperature? A. Thermal energy is the total potential energy of the particles in a substance. The lake is larger, so it contains more total particles than the swimming pool. The thermal energy of a lake is greater than a swimming pool because the lake is larger. B. Thermal energy is the total kinetic energy and potential energy of the particles in a substance. The lake is larger, so it contains more total particles than the swimming pool. The thermal energy of a lake is greater than a swimming pool because the lake is larger. C. Thermal energy is the total kinetic energy of the particles in a substance. The lake is more spread out, so it contains fewer total particles than the swimming pool. Therefore, the thermal energy of a lake is less than that of a swimming pool. D. Thermal energy is the total potential energy of the particles in a substance. The lake is more spread out, so it contains fewer total particles than the swimming pool. Therefore, the thermal energy of a lake is less than that of a swimming pool. i think it is B, but can someone help me if im correct or not?

Which simple machine is best suited to assist with the task of moving heavy objects into a moving truck 1.5 meters above the groundA. screw
B. pulley
C. wedgd
D. inclined plane

Answers

Inclined plane because its purpose is to bring objects onto vechiles. Example: The ramp on a UHaul is an inclined plane.

Final answer:

The inclined plane is the best simple machine to assist with moving heavy objects into a truck. It allows for less force to be used by distributing the required force over a longer distance.

Explanation:

The simple machine that is best suited to assist with the task of moving heavy objects into a moving truck 1.5 meters above the ground is the inclined plane (option D).

An inclined plane is a flat surface that is inclined or sloped, which allows us to move objects up or down with less force. By using an inclined plane such as a ramp, we can reduce the amount of force needed to lift the heavy objects into the truck.

For example, instead of trying to lift a heavy object straight up into the truck, which would require a significant amount of force, we can use an inclined plane to gradually raise the object by pushing it up the inclined surface. This allows us to distribute the required force over a longer distance, making it easier to move the object.

a wagon is pulled at a speed of 0.40 m/s by a horse exerting an 1,800 newton horizontal force. what is the power of this horse.

Answers

1,800/0.40=4500 this is the equation you need F=ma then you take f which is 1800 and divided by a which is 0.40 to find m

A cat lifting a barbell of 2.5 kg a distance of 3 meters. How much work is done lifting the barbell? How much work is done if the cat holds the barbell over his head for 3 minutes?

Answers

Work = (force) x (distance)

Force = weight of the barbell = (mass) x (gravity) = (2.5 kg) x (9.8 m/s²)

Work = (2.5 x 9.8 newtons) x (3 meters) = 74 newton-meters = 74 joules.

It takes 74 joules to lift the 2.5-kg load 3 meters up off the floor.

After that, as long as the load is held motionless, no more work is done.
