Mastering physics to understand how to compute the work done by a constant force acting on a particle that moves in a straight line. in this problem, you will calculate the work done by a constant force. a force is considered constant if f⃗ (r⃗ ) is independent of r⃗ . this is the most frequently encountered situation in elementary newtonian mechanics.

d

explanation:

v=uf/(u-f)

= 5.10/(5-10) convex lens has positive focal length

=50/-5

=-10 cm (formed at other side)

  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

at right angles to each other
