The part of the atom that carries a positive charge is the _____, and the part that carries a neutral charge is the _____.neutron; proton
electron; proton
proton; electron
proton; neutron

Answers

Answer : Option D) Proton and Neutron.

Explanation : The part of the atom that carries a positive charge is the proton, and the part that carries a neutral charge is the neutron.

A proton is a small subatomic particle, denoted by symbol p or p^(⁺), with a positive electric charge of +1 e elementary charge and a mass which is slightly less than that of a neutron. It is located at the center o atomic nucleus along with neutron. The number of protons are equal to the number of electrons of that atom but are in opposite charges.

A neutron is a subatomic particle of an atom which is of the same mass as that of proton but without an electric charge, it is present in all atomic nuclei except those of ordinary hydrogen. It is also located at the center of an atomic nucleus.
Proton; neutron
Protons have a positive charge
Neutrons are neutral
Electrons have a negative charge :)

Suppose you are asked to find the area of a rectangle that is 2.1-cm wide by 5.6-cm long. Your calculator answer would be 11.76 cm2 . Now suppose you are asked to enter the answer to two significant figures. (Note that if you do not round your answer to two significant figures, your answer will fall outside of the grading tolerance and be graded as incorrect.)

Answers

1) ALL non-zero numbers (1,2,3,4,5,6,7,8,9) are ALWAYS significant.2) ALL zeroes between non-zero numbers are ALWAYS significant.3) ALL zeroes which are SIMULTANEOUSLY to the right of the decimal point AND at the end of the number are ALWAYS significant.4) ALL zeroes which are to the left of a written decimal point and are in a number >= 10 are ALWAYS significant.

so it will be 11.76 = 12 bc 7 rounds up

A box experiences a force of 2 N to the left and 3 N to the right. Which is true of the box's motion?

Answers

Answer:

The box will experience acceleration

Explanation:

The box experiences unbalanced forces and will, therefore, accelerate in other words, the force applied on it from the right is greater than that exerted on it from the left.
the box is expected to go to the right since the 3N is stronger than the 2N and the rightward force will over come the leftward force.
