Answer:

Bob provided the greatest impulse.

Explanation:

Given:

Arnold exerts force = 300 N for 3 seconds

Bob exerts force = 500 N for 2 seconds

Cecil exerts force = 200 N for 4 seconds.

Find:

Highest impulse

Computation:

Impulse = Force × TIme

Arnold provides impulse = 300 N × 3 seconds = 900 N/s

Bob provides impulse = 500 N × 2 seconds = 1,000 N/s

Cecil provides impulse = 200 N × 4 seconds = 800 N/s

Therefore, Bob provided the greatest impulse.

Suppose an asteroid had an orbit with a semimajor axis of 4 au. how long would it take for it to orbit once around the sun?
Nitella [24]

It would take <u> 8 years </u> for the asteroid to orbit once around the sun.

What is a semimajor axis?

  • In geometry, the major axis of an ellipse is its longest diameter: a line segment that runs through the center and both foci, with ends at the two most widely separated points of the perimeter.
  • The semi-major axis (major semiaxis) is the longest semidiameter or one half of the major axis, and thus runs from the centre, through a focus, and to the perimeter.
  • The semi-major axis of a hyperbola is, depending on the convention, plus or minus one half of the distance between the two branches.
  • Thus it is the distance from the center to either vertex of the hyperbola.
  • In astronomy, the semi-major axis is one of the most important orbital elements of an orbit, along with its orbital period.
  • For Solar System objects, the semi-major axis is related to the period of the orbit by Kepler's third law.

_____ is the transfer of thermal energy between two bodies which are at different temperatures. The si unit for this is the joul
ss7ja [257]

Answer:

Heat

Explanation:

The thermal energy is usually defined as a heat energy that occurs due to the increase in temperature. Due to this increasing temperature, the atoms, as well as the molecules, start to migrate at a much faster rate and rapid collisions occur with one another.

This temperature change that is involved in this process can be measured.

Thus, in thermal energy, heat (heat energy) is transferred from one body to another at different distinct temperatures.

The SI unit of heat is Joule.
