Answer:

400 Joules

Explanation:

From the question,

The total kinetic energy of the water balling when hits the ground is given as

K.E = 1/2mv².................. Equation 1

Where K.E = Kinetic Energy of water ballon, m = mass of water balloon, v = velocity of water ballon

Given: m = 2 kilograms, v = 20 meters/second.

Substitute these values into equation 1

K.E = (2×20²)/2

K.E = 2×400/2

K.E = 400 Joules

What is an alloy? A. A substitution of one metal for another metal B. A metal with a changed oxidation state C. A combination of
raketka [301]

The correct answer is the combination of a metal with another element.

An alloy is a combination of two or more metallic elements to make a stronger material. For instance, there are bronze alloys, brass alloys, and coin alloys.

We can confirm that an alloy is a combination of one metal with another metal  because stainless steel is made of an iron and chromium alloy (iron is a metal; chromium is also a metal). Therefore, we can confirm that option C is the best choice.

Can you identify an atom without knowing numbers of neutrons in it?​
Masja [62]

Answer:

No

Explanation:

We cannot identify an atom without knowing numbers of protons in the atom.

The number of neutrons is the amount of neutrally charged particles in an atom. These subatomic particles occupy the dense nucleus with the protons.

  • To determine an atom, we use their atomic numbers.
  • Atomic number is the number of protons in an atom.
  • Protons are the positively charged particles in the atom.
  • The periodic table of elements is arranged by the atomic number of an element.
