find the force required to produce iacceleration of 2 metre per second square on a body of mass 10 kg what will be its acceleration if a force is double

The wording of the problem leaves much to be desired. It does not indicate in which direction is the object’s acceleration. It also fails to mention the presence or absence of friction. In order to cover all conditions, the answer must be a range of values, with the direction changing from zero to ninety degrees.

The range would be: 20 N to 120 N (100 + 20 = 120) starting from zero all the way up to ninety degrees.

wavelength divides in half and speed stays the same.

  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
