You drive 3.4 km in a straight line in a direction 6.9º east of north. if an alternate route to this same destination takes you straight east and then turns directly north to arrive at the same point, find the distance you would have to drive north.

You would have to drive in north direction 0.41km

Explanation:

We can solve this with trigonometry, We know that:

So the distance I will have to drive in north direction is 0.41km

  the unit of the measure =

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
