Calculate the acceleration if force is equal to 50 and the mass is 45

Answers

Answer 1

Answer: We can't calculate the acceleration until we know the units
of your force and your mass.

F is only equal to M·A if your 'M' is in kilograms and you 'F' is in newtons.

If your force is in, say, pounds, and your mass is in, like, metric tons,
then we would need a slightly different equation.

For the examples below, explain what a physical change or a chemical change has occurred. Justify your answerA. When you mix baking soda and vinegar, carbon dioxide is released.

B. You build a tall sand castle at the beach. After wave washes it over, the sand castle turns into a big pile of sand

C. Boiling water turns a raw egg into a hard boiled egg

D. Max divided cookie dough into small pieces on a cookie sheet.

E. A loaf of freshly baked bread tastes better and looks much different than a lump of bread dough

F. A glass of water is left in the Sun. In the time, the water evaporates leaving the glass empty.

Answers

Letters A, E, and F undergo chemical change because new substances are formed as to carbon dioxide, bread, and water vapor respectively, whereby letters B, C, and D undergo physical change because the tall sand castle remains as sand, the raw egg remains as an egg as it hardens (boiled) and the cookies remain as cookies no matter how many times it was divided into smaller pieces. The later substances' chemical composition were never changed nor formed new substances as they undergo physical processes.

Two planets of the same mass are observed.Which of the following distances between the two planets would result in the least gravitational attraction?

A. 90 light years
B. 80 light years
C. 60 light years
D. 50 light years

Answers

It really doesn't matter what mass the planets have, or whether they're equal, or whether they're planets. The farther apart two objects are, the less gravitational attraction there is between them.

As the distance increases, the gravitational force between them decreases.
So, the option with the largest distance is (A) 90 light yrs. And that's the answer !!
