*Average Speed v = d/t Distance d = v t

Time t = d/v

* remember v = average speed

Solve the following problems for average speed, distance or time. Round to tenths place:

Find the distance traveled by a car that travels with an average speed of 110 km/h for 3.5 h.

How long does it take a baseball moving with an average speed of 35 m/s to travel 18 m?

What is the average speed of a car that travels 870 km in 14.5 h?

  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

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
