PLEASE ANSWER NOW!!! This Chart Shows What Happens When Each Object Is Placed On A Balance With A 10

Answers

Answer 1

Answer:

Balanced forces do not cause a change in motion. When balanced forces act on an object at rest, the object will not move. ... Forces that cause a change in the motion of an object are unbalanced forces. Unbalanced forces are not equal and opposite.

Explanation:

Any push or pull is a force. To describe a force, you must know two things. You must know the size of the force and the direction of the force. Suppose two teams are playing tug of war. Each team is pulling with equal force, but in opposite directions. Neither team can make the other team move. Forces that are equal in size but opposite in direction are called balanced forces.

tug of war balanced

Balanced forces do not cause a change in motion. When balanced forces act on an object at rest, the object will not move. If you push against a wall, the wall pushes back with an equal but opposite force. Neither you nor the wall will move. Forces that cause a change in the motion of an object are unbalanced forces.

tug of war unbalanced 1

Unbalanced forces are not equal and opposite. Suppose that one of the teams in tug of war pulls harder than the other team. The forces would no longer be equal. One team would be able to pull the other team in the direction of the larger force.

Force and Motion

More than one force can act on an object at the same time. If you hold a paper clip near a magnet, you, the magnet and gravity all exert forces on the paper clip. The combination of all the forces acting on an object is the net force. When more than one force is acting on an object, the net force determines the motion of the object. In this example, the paper clip is not moving, so the net force is zero.

How do forces combine to form the net force? If the forces are in the same direction, they add together to form the net force. Suppose you and a friend are asked to move a piano for the music teacher. To do this, you pull on one end of the piano, and your friend pushes on the other end. Together, your forces add up to enough force to move the piano. This is because your forces are in the same direction. Because the forces are in the same direction, they can be added together to determine the net force. In this case, the net force is 45 N, which is plenty to move a piano - if it is on wheels, that is!

net force piano

If two forces are in opposite directions, then the net force is the difference between the two forces, and it is in the direction of the larger force. Consider two dogs playing tug of war with a short piece of rope. Each is exerting a force, but in opposite directions.

Notice below that the dog on the left is pulling with a force of 10 N, and the dog on the right is pulling with a force of 12 N. Which dog do you think will win the tug of war? Because the forces are in opposite directions, the net force is determined by subtracting the smaller force from the larger one. In this case, the net force is 2 N in the direction of the dog on the right. Give that dog a dog biscuit!

Look at the unbalanced reaction below for the combustion of hydrogen gas. What needs to be done to balance the reaction? _ H2 + _O2 LaTeX: \longrightarrow⟶ _H2O

Answers

Answer:

The given equation H2 + O2 => H2O is not balanced as the oxygen atom on the right side do not have the same number of atoms as of the left side.

In a balanced equation, the number of atoms on both sides are equal. So in this case, we are required to change the coefficient in front of H2O, in order to make oxygen atom balance, for that we need to change the coefficient of H2 as well.

It means to make the given equation balance we need to change the coefficient in front of H2 and H2O.

Balance equation: 2H2 + O2 => 2H2O

A car accelerates from 0 to 72 km/hour in 6.0 seconds. What is the car's acceleration?

Answers

The car's acceleration is 12 km/second^2

The acceleration of the car is equal to 3.33 m/s² with a velocity of 72 Km/hr.

What is acceleration?

Acceleration can be demonstrated as the rate of change of velocity over time. The acceleration can be explained as vector quantity due to both magnitude and direction. Acceleration is defined as the 2nd derivative of the position of the object w.r.t. time.

According to Newton's 2nd law of motion, the force exerted is equal to the mass times of acceleration of an object.

a = F/m

or, a = dv/dt

Given, the final velocity of the car, v = 72 Km/hr

v = 72 × 1000/3600 m/s

v = 20 m/s

The time is taken by car to travel, t = 20 s

The acceleration of the car, a = (20 - 0)/(6 - 0)

a =  3.33 m/s²

Therefore, the acceleration of the car is 3.33 m/s².

Use the periodic table to determine which statement below is true of the element Bromine (Br).

•Bromine will lose 7 valence electrons to become a negative ion.
•Bromine will lose 7 valence electrons to become a positive ion.
•Bromine will gain 1 valence electron to become a negative ion.
•Bromine will gain 1 valence electron to become a positive ion.

Answers

Answer:

The correct option is;

Bromine will gain 1 valence electron to become a negative ion

Explanation:

Bromine can be found in period 4 in group 17 of the periodic table and is an halogen

The electron configuration of bromine can be presented as follows;

Electronic configuration 1s²2s²2p⁶3s²3p⁶3d¹⁰4s²4p⁵

Therefore, an atom of bromine has 2 + 5 or 7 electrons in its outermost shell, which makes it have one less electron to complete a full octet structure and therefore, bromine has a strong affinity for electron to complete its octet structure and it is thus a strong oxidizing agent.

When bromine enters into a chemical reaction and gains the one valence electron it becomes a negatively charged ion.

In coulombs, how much positive charge is there IN a barium nucleus? On a barium ion?

Answers

Answer:

The amount of positive charge in a barium nucleus is approximately 8.972 × 10⁻¹⁸ coulomb

Explanation:

The amount of positive charge there is in a barium nucleus is found as follows;

The atomic number of an element is equal to the number of proton present in the atom

The atomic number of barium = 56 = The number of protons in an atom of barium

The positive charge of a single proton is known as an elementary charge, e, given by the formula, e = F/N[tex]_A[/tex]

Where;

F = Faraday's constant

N[tex]_A[/tex] = The Avogadro's number

Therefore, e = 1.602 176 634 × 10⁻¹⁹ C

Which gives the positive charge, Q, of the protons of a barium nucleus as follows;

Q = Number of protons × e

Q = 1.602176634 × 10⁻¹⁹ × 56 ≈ 8.972 × 10⁻¹⁸ Coulomb  per atom of barium.

The amount of positive charge in a barium nucleus ≈ 8.972 × 10⁻¹⁸ coulomb.

A student lifts a bag from the floor to his or her shoulder 1.2m above the floor, using a force of 50N. How much work does the student do on the bag ?

Answers

The formula for work is force x distance, and it is measured in joules, so the answer would be:

1.2m x 50N = 60J

60 J work does the student do on the bag.

The formula for work is as follows:-

[tex]W=F\times d[/tex]....(1)

Here, F is the force, and d is the distance moved in the direction of force.

Substitute 50 N for force and 1.2 m for distance in the equation (1) as follows:-

[tex]W=50\ N\times 1.2\ m\\\\=60\ Nm\\\\=60\ Joule[/tex]
