Answer:
G
Explanation
The acceleration of gravity is constant, and = 9.8 m/s² , no matter what mass of the object is. Initial speed for both objects = 0 m/s. So, after 2 sec the objects will have the same speed and the same distance.
Answer G: speed=v, distance =d.

If Earth was with no tilt, would we still have seasons at all? If so, how would they be different?
Answers
Answer:
If earth had no tilt, we would have no seasons.
Explanation:
As stated in the answer, if the earth had no tilt we wouldn't have seasons. The earth all around the globe would maintain the same temperature,
And due to the no tilt it would also change our orbit to a bit larger slant, in January when we are at our closest to the sun we WOULD have a mini summer. For the North and South Pole, they would remain cold.

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
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.

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.

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.
