Given two vectors A⃗=4.30i^+7.20j^ A → = 4.30 i ^ + 7.20 j ^ and B⃗=5.20i^−2.30j^ B → = 5.20 i ^ − 2.30 j ^ , find the scalar product of the two vectors A⃗ A → and B⃗ B → .

a small object of mass 3.66 g and charge -17.6 µc is suspended motionless above the ground when immersed in a uniform electric field perpendicular to the ground. what are the magnitude and direction of the electric field?

  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
