Units?
inches
milliliters
grams
centimeters
Answer:
Inches
Explanation:
An inch is a unit of measurement in the Imperial system of measurement. Everything else is used in the International System of Units.
The unit of measure never is used in the International System of Units is inches. The correct option is A.
What is International System of Units?The International System of Units, abbreviated SI in all languages and sometimes pleonastically as the SI system, is the modern version of the metric system and the world's most widely used measurement system.
The International System of Units (SI), also known as the French Système International d'Unités, is a decimal international system of weights and measures derived from and expanding on the metric system of units.
The 11th General Conference on Weights and Measures adopted it in 1960, and it is abbreviated SI in all languages.
The International System of Units (SI) is a measurement system based on seven basic units: the metre (length), kilogram (mass), second (time), ampere (electric current), kelvin (temperature), mole (quantity), and candela. These base units can be combined with one another.
Thus, the correct option is A.

What is the general shape of the graph line?
A positively sloping diagonal
A negatively sloping diagonal
A half-parabola
A hyperbola
Answer:
A
Explanation:
Positive slope lines have a left to right ascent. A negative slope is present on lines that descend from left to right. Consequently, a diagonal line with a positive slope (/) would be to the right. Thus, option A is correct.
What is positively sloping diagonal?The height difference between two tile corners that is on the diagonal. A hidden value is used to determine if a tile can be seeded on, passed by a cart, or have the corner of the pavement tile lowered.
When two variables have a positive slope, it means that they are positively correlated; that is, when x rises, y rises as well, and when x falls, y falls as well.
A line on a line graph that has a positive slope rises as the line advances from left to right.
Be aware that a line's positive slope causes it to slope upward from left to right. Remember that a line with a negative slope descends from left to right. Keep in mind that a line has no slope when it is horizontal.
Therefore, positively sloping diagonal general shape of the graph line.

Q3. At an altitude of 6679 km above the center of the Earth, the
International Space Station can complete one orbit in 1.5 hours.
Determine the average speed of the ISS. Explain why you should
calculate speed in this case, and not velocity.
Answer:
5524.8 m/s
Explanation:
Given that,
Altitude above the surface of earth is 6679 km, the Space Station can complete one orbit in 1.5 hours. We need to find the average speed of the ISS. The average speed of its orbit is given by :
[tex]v=\sqrt{\dfrac{GM}{R}}[/tex]
R is distance from Earth
R = r + d, r is the radius of Earth
R = 6371 + 6679
R = 13050 km
So,
[tex]v=\sqrt{\dfrac{6.67\times 10^{-11}\times 5.972 \times 10^{24}}{13050\times 10^3}}\\\\v=5524.8\ m/s[/tex]
or
Hence, the average speed of ISS is 5524.8 m/s.

Answer:
1. Collision- the sudden, forceful coming together in direct contact of two bodies
2. Newton's third law of motion is naturally applied to collisions between two objects. In a collision between two objects, both objects experience forces that are equal in magnitude and opposite in direction.
3. Momentum is the product of a moving object's mass and velocity. When two objects collide the total momentum before the collision is equal to the total momentum after the collision

How can the motion of an object that is already moving change?
How can the motion of an object thatnis NOT moving change?
Answer:
"They may cause motion; they may also slow, stop, or change the direction of motion of an object that is already moving. Since force cause changes in the speed or direction of an object"
"When a force acts on an object that is stationary or not moving, the force will cause the object to move, provided there are no other forces preventing that movement."
The answer to both questions is the same answer:
That can only happen if force acts on the object.

Explanation:
A penny is dropped from the top of a building 290 m high. Ignoring air resistance, if
the penny falls straight down, with what speed would it hit the ground?
Answer:
Vf = 75.4 m/s
Explanation:
In order to find the final velocity of the penny when it would hit the ground, we will use the equation of motion. In this particular case the third equation of motion can be used. The third equation of motion is written as follows:
2gh = Vf² - Vi²
where,
Vf = Final Velocity of the penny when it would hit the ground = ?
Vi = Initial Velocity of the penny = 0 m/s (Since, the penny starts from rest)
g = acceleration due to gravity = 9.8 m/s²
h = height of building = 290 m
Therefore,
2(9.8 m/s²)(290 m) = Vf² - (0 m/s)²
Vf = √(5684 m²/s²)
Vf = 75.4 m/s

What is a Conceptual Model?
A system is portrayed in a conceptual model. It consists of ideas that aid in knowing, comprehending, or simulating the subject the model portrays.
A variety must be stable for it to be a true explanation. When sugar is completely dissolved in water, it can stand without the sugar dissolving again for an unlimited period of time. In addition, the sugar will stay in the water if the sugar-water solution is filtered.
This is due to how tiny the liquefied particles are in a solution—they typically have a diameter of less than 1 nm. Depending on the type of nature that has been dissolved, solute particles might be particles, ions, or molecules.
Hence, option A is a scenario of a conceptual model

What is its average acceleration in this time
interval?
Answer:
Unlike acceleration, the average acceleration is calculated for a given interval. Here, Δ v is the change in velocity and Δ t is the total time over which the velocity is changing. If the velocity of a marble increases from 0 to 60 cm/s in 3 seconds, its average acceleration would be 20 .
A -0.06 charge that moves downward is in a uniform electric field with a strengthened of 200 N/C. What is the magnitude and direction of the force on the charge
Answer:
The magnitude of the force is 12 N Upwards
Explanation:
The force on a positive charge will be in the same direction as the field, but the force on a negative charge will be in the opposite direction to the field. Thus the direction of the force is upward.
Given;
magnitude of charge, q = 0.06 C
magnitude of electric field, E = 200 N/C
The magnitude of the force is given by;
F = qE
F = 0.06 x 200 N/C
F = 12 N Upwards
Therefore, the magnitude of the force is 12 N Upwards
