Three displacement vectors A → , B → , and F → (Figure 2.13) are =10.00,B=7.00,andF=20.00,respective ly, angles with the horizontal direction α=35°, β =−110°, and φ=110°. The physical units of the magnitudes are centimeters. Use the analytical method to find vector G → = A → +2 B → − F → . Verify that G= 28.15 cm and that θG =−68.65°.

less than one you can't create energy

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.

  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
