A flight attendant who is walking 2 mph toward the nose of a plane that is traveling 500 miles per hour is moving at a combined velocity of?​

second mirror gathers light from a faraway object and reflects it to another mirror. - a.

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be

the body's situation won't change the forces are equal opposit and on the same body

  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
