An object has an acceleration of 18.0 m/s/s. If the net force was doubled and the mass were tripled then the new acceleration would be

Answers

Answer:

12.0 m/s²

Explanation:

Newton's second law:

F = ma

Solving for acceleration:

a = F/m

If force is doubled and mass is tripled:

a' = (2F)/(3m)

a' = ⅔ (F/m)

a' = ⅔ (18.0 m/s²)

a' = 12.0 m/s²

The new value of acceleration of object is 12 m/s².

Given data:

The magnitude of acceleration of object is, [tex]a =18 \;\rm m/s^{2}[/tex].

Let F be initial net force and m be the initial mass. Then as per the problem, the new values of each are,

F' = 2F

m' = 3m

Apply the Newton's Second law, which says that the product of mass and acceleration of object given net force. Then,

F = ma

F = m(18)

F/m = 18 .................................................(1)

Now, for new value of net force,

F' = m'a'

2F = (3m) a'

2F/3m = a'

a' =2/3× (18)                                                   (From equation 1)

a' = 12 m/s²

Thus, we can conclude that the new value of acceleration of object is 12 m/s².

identify the correct order of increasing intermolecular force of attraction for the three most common states of matter.

A) liquid - solid - gas
B) Solid - liquid - gas
C) gas - liquid - solid
D) gas - solid - liquid

Answers

I believe it’s C) gas- liquid- solid

The correct order of increasing the intermolecular force of attraction for the three most common states of matter is C) gas - liquid - solid.

What is an intermolecular force in matter?

An intermolecular force is a force of attraction or repulsion that exists between molecules or atoms within a substance.

Here,
In the gaseous state, the intermolecular forces are weak, and the molecules are far apart and move freely in all directions. In the liquid state, the intermolecular forces are stronger, and the molecules are closer together, but still able to move past each other. In the solid state, the intermolecular forces are the strongest, and the molecules are tightly packed together in a fixed arrangement, which results in a definite shape and volume.

Therefore, the correct order of increasing the intermolecular force of attraction for the three most common states of matter is gas, liquid, and solid.

The woman supports a 100 N load with the friction free pulley system shown below. Fill in the spring scale readings that show how much force she must exert.

Answers

Answer:

1. 100N 2. 50N 3. 50N

Explanation:

The spring scale reading that shows how much force she must exert is 1. 100N 2. 50N 3. 50N.

What is the spring scale?

A simple and affordable way to determine mass is by using spring balances. The mass is suspended from the end of the spring, and the spring's deflection as a result of the mass's downward gravitational pull is measured in relation to a scale.

The word "force" has a specific meaning in science. At this level, calling a force a push or a pull is entirely appropriate. A force is not something an object "has in it" or that it "contains."

One thing experiences a force from another. There are both living things and non-living objects in the concept of a force.

Therefore, her required force is indicated by the spring scale readings of 1. 100N, 2. 50N, and 3. 50N.

A tennis ball and a solid steel ball of the same diameter are dropped at the same time. Which ball has the greater amount of force acting on it?

Answers

The steel one.

The steel one has more force due to the weight and mass.

An object's mass is a crucial indicator of how much stuff it contains. The gravitational pull of an object is measured by its weight. It is influenced by the object's location in addition to its mass. As a result, weight is a measurement of force.

What ball has the greater amount of force acting on it?

The heavier (denser) object will fall quicker if two identically sized but made of different materials objects are present. This is because both objects will experience the same drag and buoyancy forces, but the heavier object will experience a stronger gravitational pull.

Things fall to the earth faster as a result of gravity. Acceleration is a modification of velocity, and velocity is a measurement of the direction and speed of motion. The longer an object is in free fall, the faster gravity makes it tumble toward the ground.

Therefore, solid steel ball have high mass and greater amount of force acting on it.

The electricity conduction happens when there is a flow of current. The flow of current from one point to another can only occur if there is a potential difference.

If there is not potential difference between two points the current will not flow and thus electricity conduction will also be not possible. The current in the circuit will flow from higher potential point to lower potential point.
