A person walks first at a constant speed of 4.90 m/s along a straight line from point A to point B and then back along the line from B to A at a constant speed of 3.05 m/s.A) What is her average speed over the entire trip?B) What is her average velocity over the entire trip?

Answers

Answer 1
Answer:

Answer:

A.) 3.975 m/s

B.) 0.925 m/s

Explanation:

Given that a person walks first at a constant speed of 4.90 m/s along a straight line from point A to point B and then back along the line from B to A at a constant speed of 3.05 m/s.

A) What is her average speed over the entire trip?

The average speed = (4.90 + 3.05)/2

Average speed = 7.95/2

Average speed = 3.975 m/s

B) What is her average velocity over the entire trip?

Since velocity is a vector quantity, that is, we consider both the magnitude and direction

Average velocity = ( 4.90 - 3.05)/2

Average velocity = 1.85/2

Average velocity = 0.925 m/s

Which of these is not a resistor?a. wire
b. light bulb
c. hair dryer
d. all of these are resistors

Answers

The correct answer is (d.) all of these are resistors. A resistor creates the reduction of the current flow and voltage levels within the circuits. A wire is a resistor because it is made up of alloy and carbon that helps to maintain a low resistance and have an easy flow of the electric charges. Same as the light bulb and the hair dryer, they all reduce the current flow.

Which is more 3 tons or 6001 pounds

Answers

3 tonnes

The answer is 3 tonnes, because 3 tonnes equal 6613.87 pounds, which is higher than 6001.

I hope this helps! I would love it if you could help me answer my question too!

Final answer:

6001 pounds is slightly more than 3 tons. This is because, in the comparison scale, 1 ton is equal to 2000 pounds. So, 3 tons equals 6000 pounds.

Explanation:

The student is asking which is more, 3 tons or 6001 pounds. To determine this, we need to understand the relationship between tons and pounds. We know that 1 ton is equivalent to 2000 pounds. So, 3 tons would be equivalent to 3*2000 = 6000 pounds.

Hence, comparing 6001 pounds with 3 tons, or effectively 6000 pounds, 6001 pounds is slightly more than 3 tons.

The average kinetic energy of the atoms that make up a substance which is changing from a liquid to a solid is _____________.Select one of the options below as your answer:
a. decreasing
b. increasing
c. unchanged

Answers

The average kinetic energy of the atoms that make up a substance which is changing from a liquid to a solid is decreasing. The answer is letter A. This  is because there is more room for movement of atoms if the pahse is in liquid than in solid.

The water at the top of a waterfall has _____ energy.potential
kinetic
heat
metabolic

Answers

I believe the answer isPOTENTIAL ENERGY. The water at the top of the waterfall has Potential Energy.Potential Energy is defined as the energy that is stored when an object is atrest. At the top of the waterfall, water will have maximum potential energy. Whenthe water falls down, it is will already have kinetic energy which is energythat is produced through continuous motion. When it is finally in the bottom,water will have maximum kinetic energy. 

Answer:

The water at the top of a waterfall has __potential___ energy.
