So, doubling the time results in double the distance covered.

Explanation

Quadratic equations have roots that can be:

“Cubic” relates to degree 3, not to root types.

Explanation

When flipping a coin 3 times, each flip has 2 possible outcomes (heads or tails).

So, the total number of outcomes is 2³ = 8.

The favorable outcome is getting 3 heads (HHH).

There is only 1 way to achieve this.

Probability = Number of favorable outcomes / Total number of outcomes = 1/8 = 0.125.

Explanation

The law of conservation of energy is based on the principle of Bernoulli's theorem.

Bernoulli's theorem states that in a steady flow of an incompressible, frictionless fluid, the total mechanical energy (sum of potential energy, kinetic energy, and pressure energy) per unit mass of the fluid remains constant along a streamline.

This means that the total energy of the fluid is conserved as long as no external forces are acting on it, such as friction or heat transfer.

Explanation
