A pizza deliverer have 5 pizzas to deliver, in the following sequence A, B,C, D and E. The pizza company have a 45 min delivery policy, that means that the 5 pizzas should be deliver in that time.

Solve:
1) Calculate the total displacement of the deliverer.
NOTES:
You should use Pythagoreans theorem to find the distance between some points (A, B,C, D,E).
The units of the cartesian plane are km. (use 4 digits after the point in your calculations).
The deliverer start moving from 0 (that’s the direction of the pizza place) and finish in E (the last house).

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
