Answer:

C

Explanation:

The kinetic energy of a body is the energy due to the motion of a body. It is mathematically given as;

 Kinetic energy  = \frac{1}{2} m v²

m is the mass of the body

v is the velocity

 Now, let us find the K.E from the given choices;

Option C will have the greatest kinetic energy;

         mass  = 0.14kg , v  = 40m/s

 Kinetic energy  = \frac{1}{2} x 0.14 x 40²   = 112J

What is mass in grams of
ELEN [110]

The mass in grams 550 mL of salt water with a density of 1.50 g/cm³ is 825grams.

<h3>DENSITY:</h3>
  • The mass of a substance can be calculated by multiplying the density of the substance by its volume. That is;

Mass = density × volume

  • According to this question, the volume of the salt is 550mL while its density is given as 1.50g/mL. The mass is calculated as follows:

Mass = 1.50g/mL × 550mL

Mass = 825grams.

Therefore, the mass in grams 550 mL of salt water with a density of 1.50 g/cm³ is 825grams.
