Which does more work, a force of 500 N moving through 10 m or a force of 100 N moving through 40 m?

Answers

Answer 1

Answer:

Explanation:

To determine which force does more work, we can calculate the work done by each force using the formula:

Work = Force × Distance

For the first scenario:

Work = 500 N × 10 m = 5000 N·m

For the second scenario:

Work = 100 N × 40 m = 4000 N·m

Therefore, the force of 500 N moving through 10 m does more work, with a total of 5000 N·m.

A pet turtle moves 30.1 mm in 72s. how slow is it moving? is this a speed or a velocity?

Answers

The pet turtle is moving at a certain speed, and to determine how slow it's moving, we can calculate its speed.

Speed is a scalar quantity, which means it only has magnitude and no direction. Velocity, on the other hand, is a vector quantity and includes both magnitude and direction.

To calculate the speed of the turtle, you can use the formula for speed:

Speed (S) = Distance (D) / Time (T)

In this case, the turtle moves 30.1 mm in 72 seconds:

S = 30.1 mm / 72 s

To make the units more convenient, we can convert millimeters to meters (1 meter = 1000 millimeters):

S = (30.1 mm / 1000) m / 72 s

S ≈ 0.000301 m / 72 s

Now, let's calculate the speed:

S ≈ 0.00000418056 m/s

So, the pet turtle is moving at a speed of approximately 0.00000418056 meters per second.

It's important to note that this is indeed a speed, not a velocity, because it only provides the magnitude of the motion (how fast it's moving) without specifying a direction.

Given the diamond shape of a baseball field in the speed of which baseballs or hit why is it harder for a hitter to hit a homerun to the center field then to the right or left field

Answers

Because, say the diamond was 125 feet on both right and left fields, the center field would be 130 feet long, see what i mean? I hope I helped. :)

Please help me!!!!!!!What role does voltage play in the formation or use of an electromagnet?

Answers

The voltage drives the necessary force for an electromagnet to work. The strength of an electromagnet depends on the electric current which flows through its wires, but not on what drives the current.

PLEASEEE HELP, thank you :)

Answers

Answer:

The answer is B.

Explanation:

Given that the current (Ampere) in a series circuit is same so we can ignore it. We can assume that the total voltage is 60V and all the 3 resistance are different, 20Ω, 40Ω and 60Ω. So first, we have to find the total resistance by adding :

Total resistance = 20Ω + 40Ω + 60Ω

=120Ω

Next, we have to find out that 1Ω is equal to how many voltage by dividing :

120Ω = 60V

1Ω = 60V ÷ 120

1Ω=0.5V

Lastly, we have to calculate the voltage at R1 so we have to multiply by 20 (R1) :

1Ω = 0.5V

20Ω = 0.5V × 20

20Ω = 10V
