sandpaper
slip n slide
slip n slide coated with oil
surface of your desk

Answers

Answer 1
slip and slide covered with oil
Answer 2
should be slip n slide with oil since it’s more likely to create more friction than just a normal slip n slide.

Add all the net forces together and that number will be your new net force and that’s how it done
If the arrows are in the same direction then you have to add them. If the arrows are in opposite you have to take away. For example for question 5 8-4=4 so thE net force will be 4 and the arrow will be left as 8N is bigger. For question 4 they are in the same direction so you add them it will be 9N to the right. For question 3 they are in opposite so it will be 0 and both arrows are equal so the net force is 0 and then object is stationary

Answer:

Hope this helps

Explanation:

As we know our atmosphere or air have different levels. Every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.

How would conditions on Earth be different if its axis did not tilt? *
A There would be no seasons.
B There would be no years.
C There would be no temperature
D The equator would not be as warm in winter.

Answers

If the earth didn't have a tilt, we wouldn't have seasons. Instead, the environment would be unchanging, and the temperature would vary upon latitude. Equatorial regions would be constantly hot and humid, and polar regions would always be cold. There would no variability to the climate as the year progresses.
I think the answer is C

.1
.01

Answers

Answer:

0.01

it has the least amount of resistance

A push on a 1-kg brick accelerates it. Neglecting friction, equally accelerating a 10-kg brick requires 10 times as much force. Using your knowledge of Newton’s Second Law, explain why this is correct.

Explanation:

A heater has a resistance of 10.0 Ω. It operates on a 12.0 V. What is the current through the resistor?

         Known:

R = 10.0 Ω                            V = 12.0 V

       Unknown:

I = ???

I = V/R

= 12.0 V / 10.0 Ω

= 1.2 amps
