An object of mass 3.4 kg is moving in a straight line with kinetic energy 59.177 J. A force is applied in the direction of its motion for 2.7 seconds, and as a result, its kinetic energy is multiplied by a factor of 1.57. By what factor is its momentum multiplied?

Its momentum is multiplied by a factor of 1.25

Explanation:

First, we calculate the initial velocity of the object:

With that velocity we can calculate the initial momentum of the object:

Then we calculate the velocity of the object once its kinetic energy has increased:

And calculate the second momentum of the object:

Finally we calculate the factor:

the temperature and the pressure affect solubility. temperature affects by changing the properties of the solvent. the increase in pressure increases solubility, the decrease in pressure decreases solubility.

a.metals can become magnetic if they have many spinning electrons that create magnetic fields.d.only some metals are attracted by magnets; these metals are called ferromagnetic.

d.wrapping an insulated wire around a metal with ferromagnetic properties and applying an electric current.
