1.When I cook an egg in a microwave oven, the device uses electromagnetic energy to increase the kinetic energy of particles of

matter in the egg.
2.Many stoves and ovens have exhaust fans overhead to remove the rising warm air from the kitchen. The thermal energy is added to air and it rises.

3.When I cook an egg in a pan, thermal energy is transferred as the egg touches the hot surface of the pan. The thermal energy is transferred as objects touch.

The graph below represents the relationship between speed and time for an object moving along a straight line. What is the total
KiRa [710]

The distance travelled by the object during the first 4 seconds is 80 m

<h3>Definition of speed </h3>

Speed is defined as the distance travelled per unit time. Mathematically, it can be expressed as:

Speed = distance / time

With the above formula, we can obtain the distance travelled by the object in the first 4 seconds.

<h3>How to determine the distance travelled </h3>
  • Speed = 20 m/s
  • Time = 4 s
  • Distance =?

Speed = distance / time

20 = distance / 4

Cross multiply

Distance = 20 × 4

Distance = 80 m

Anika [276]
No, gravity acts equally on all objects.  The crumpled paper falls faster because it resists the drag force due to the atmosphere because of its compact size.  A flat piece of paper has an extended body and "catches" the air and falls more slowly.  In a vacuum they would fall at the same rate either way.
