Kinetic energy is energy of motion. The kinetic energy of an object is dependent on two variables, speed and mass and can be represented by the formula:
KE = 1/2mv2
Sammie is speeding done the road in his race car. Sammie passes one car after another. Sammie has more kinetic energy than the
cars he is passing. He pulls up to a BIG truck and the two are traveling neck and neck down the highway. Is there any difference in
the kinetic energy of the truck and Sammie's car? Explain.

b..

is the correct one

explanation:

covalent bonds form as valence electrons are shared between two atoms. lewis structures and structural formulas are common ways of showing the covalent bonding in organic molecules. formal charge describes the changes in the number of valence electrons as an atom becomes bonded into a molecule.

a basic solution is an aqueous solution containing more oh-ions than h+ions. in other words, it is an aqueous solution with a ph greater than 7. basic solutions contain ions, conduct electricity, turn red litmus paper blue, and feel slippery to the touch.

explanation:

pure substance: iron,copper

impure substance: water,charcoal

it is to be noted that an alpha particle is an helium nucleus. so it contains 2 protons 2 neutrons and has a mass number of 4. when alpha decay particles are ejected from the nucleus it gets transformed into an atom which has atomic number less than 2 and a mass number less than 4.

an equation that could represent alpha decay is radium 226 decay of alpha particle forms radon 222.
