A worker pushes horizontally on a large crate with a force of 265.0 N and the crate moved 4.3 m. How much work was done?
trapecia [35]

Answer:

<h2>1139.5 J</h2>

Explanation:

The work done by an object can be found by using the formula

workdone = force × distance

From the question we have

work done = 265 × 4.3 = 1139.5

We have the final answer as

<h3>1139.5 J</h3>

Hope this helps you

Friction removes energy from objects in motion. Which statement best describes how this works?
xenn [34]

<em>friction transforms KE into thermal energy (a)</em>

That's why, if it goes on long enough, the moving object actually gets warm.

The repulsive force between two protons has a magnitude of 2.00 N. What is the distance between them?
Aloiza [94]

Answer:

The answer to your question is letter A.     r = 1.07 x 10⁻¹⁴ m

Explanation:

Data

F = 2 N

d = ?

q = 1.6 x 10 ⁻¹⁹ C

k = 8.987 Nm²/C²

Formula

                 F = K\frac{q1q2}{r^{2}}

Solve for r

                r = \sqrt{\frac{kq1q2}{F}}

Substitution

                r = \sqrt{\frac{8.987 x 10^{9}x1.6 x 10^{-19} x 1.6 x 10x^{-19}}{2}}

Simplification

                r = \sqrt{\frac{2.3 x 10^{-28}}{2}}

                r = \sqrt{1.15 x 10^{-24}}

Result

                r = 1.07 x 10⁻¹⁴ m

__ modified the concept by adding an internal combustion engine and marketing hybrids that were part electric and part gas power

Hybrid

<u>Hybrid</u> modified the concept by adding an internal combustion engine and marketing hybrids that were part electric and part gas powered.

  • The driving wheels of hybrid vehicles receive power from their drivetrains.
  • A hybrid car has numerous sources of propulsion.
  • There are numerous hybrid configurations.
  • A hybrid vehicle might, for instance, get its energy from burning gasoline while alternating between an electric motor and a combustion engine.
  • Although they have primarily been employed for rail locomotives, electrical vehicles have a long history of integrating internal combustion and electrical transmission, like in a diesel-electric power-train.
  • Because the electric drive transmission directly substitutes the mechanical gearbox rather than serving as an additional source of motive power, a diesel-electric powertrain does not meet the definition of a hybrid.
  • Only the electric/ICE hybrid car type was readily accessible on the market as of 2017.
  • One type used parallel operation to power both motors at the same time.
  • Another ran in series, using one source to supply power solely and the other to supply electricity.
  • Either source may act as the main driving force, with the other source serving to strengthen the main.
