. What is the kinetic energy of a jogger with a mass of 65.0 kg traveling at a speed of 2.5 m/s?

The branch of science which deals with the chemicals bond is called chemistry.

The correct answer is 20.3125J

The energy formed by the motion of particles is called kinetic energy. The formula is half of the product of the mass and velocity.

After putting the value:-

After solving the equation, the kinetic energy is 20.3125Joules.

Hence, the correct answer is 20.3125Joules.

Kinetic energy=1/2mv^2.

1/2×65×2.5^2.

1/2×6.5×6.25.

1/2×40.625.

=20.3125Joules.

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
