If you had a notebook and a pencil on the a table, what would happen if they were both to fall off
A. The mass of objects would be similar
B. Gravity would pull them to the ground.
C. The acceleration of these two objects would be different for both
D. Gravity would make the notebook fall sooner because it is heavier
Answer: b
Explanation:
If someone showed you two spheres of the same size but with different masses, say 1g and 10kg, and asked which would hit the ground first after being dropped from the Leaning Tower of Pisa, what would you say? If you’re like most people, you would say the 10kg sphere would hit the ground first. Aristotle said so too, and for 1,000 years everyone believed him. But doing the experiment would show you, besides a great view of Pisa, that in fact, both spheres hit the ground at the same time.This is exactly what Galileo did, showing the world that objects of different masses fall at the same rate. (This is also a good example of why it is important to do experiments yourself and not to just take someone else’s word for it.) To start understanding why Galileo was right, we need to understand the difference between several physics words that are often jumbled together and confused: mass, weight, speed, velocity, acceleration, and force.
What does it mean to say that friction resists motion? And how is inertia similar to Newton’s 1st law?
Answer:
1.Friction is a catchall word that refers to any force that resists relative tangential motion (or intended motion). "Relative tangential motion" is a fancy way to say "slipping" or "sliding". Its direction is opposite the relative velocity (or intended velocity).
2.Newton’s first law of motion states that a body at rest remains at rest, or, if in motion, remains in motion at a constant velocity unless acted on by a net external force. This is also known as the law of inertia. Inertia is the tendency of an object to remain at rest or remain in motion. Inertia is related to an object’s mass.

I have 2 questions.
1."Describe the relationship between mechanical wave's amplitude and its energy"
2."What is the relationship between a light waves' amplitude and its brightness"
Answer:
1) The amount of energy carried by a wave is related to the amplitude of the wave.The more displacement that is given to the first coil, the more amplitude that it will have. So in the end, the amplitude of a transverse pulse is related to the energy which that pulse transports through the medium.
2)The amplitude of a wave tells us about the intensity or brightness of the light relative to other light waves of the same wavelength. Both Wave 1 and Wave 2 have the same wavelength but different amplitudes. The wavelength of light is an important property for it is this that determines the nature of the light.

Explanation:
What is the net force acting on an object?
If an object has two forces acting on it, how can the net force equal 0?
Under what conditions does the net force acting on an object equal the sum of the individual forces?
Answer:
If two forces act on an object in the same direction, the net force is the sum of the two forces. In this case, the net force is always greater than either of the individual forces.

Lucia is playing with magnetic toy vehicles. She has two identical toy vehicles (purple and pink) that start on opposite sides of a center magnet that cannot move. She moves both vehicles one space closer to the center magnet.??? what
Answer: The potential energy of both toy vehicles (purple and pink) decreased. Since the pink toy was moved closer to the magnet, it will have less potential energy because of the short distance it will take to travel to the magnet.
Explanation:
Brainliest
Answer:
The potential energy of the two vehicles increased because they were moved against the magnetic forces. The potential energy of the pink car increased more then the potential energy of the purple car because the pink car was closer to the center magnet. Therefore the pink car been closer to the center magnet will experience a higher change in its potential energy than the purple car.

Write how gravity and the mass of the pack affected the motion of the pack when it was thrown at different forces.
Answer:
A rocket with more mass will speed up more slowly, just as in the horizontal example, but there is another effect. The force of gravity is now acting in the opposite direction to the thrust, so the resultant force pushing the rocket upwards is also less.
Explanation:
The greater the mass of the pack, the heavier the pack becomes (increased weight due to gravity) and the motion of the pack will be reduced. On the other hand, if the mass of the pack is reduced, the pack becomes lighter (reduced weight due to gravity) and the motion will increase.
According to Newton's second law of motion, the force applied to an object is directly proportional to the product of mass and acceleration of the object.
F = mg
where;
m is the mass of the objectg is the acceleration due to gravityF is the applied forceFrom the equation above, the greater the mass of the pack, the heavier the pack becomes (increased weight due to gravity) and the motion of the pack will be reduced. On the other hand, if the mass of the pack is reduced, the pack becomes lighter (reduced weight due to gravity) and the motion will increase.

Satellite views help scientists they give scientists the ability to predict catastrophic events.
What is topographic maps?A topographic map depicts the geographical features of the region. They might make use of them to make sure their designs are on the proper road. It shows the elevation of a building site. Thus option D is correct.
Soil erosion is the process of flowing of soil with water during heavy rains or floods. Plant roots are strongly adhered and they strongly holds the soil under roots. They helps prevent erosion.
The term deposition means the laying down of sediments. Rock sediments sands, and other minerals undergo sedimentation.
Satellite views helps scientists the ability to predict catastrophic events. Satellites study changes occurring around planet and forecast the presence of extra terrestrial objects and their movements.

Jax fell while running and cut his knee. He noticed at the end of the day that his body had produced a hard film over his scrape. After two weeks, his scrape was completely gone and new skin had formed where his scrape had been. Which bodily system was repaired in order to protect the soft body tissues below Jax's skin?
Answer:
INTEGUMENTARY
Explanation:
The integumentary system repaired his scrape in order to protect the soft body tissues below Jax's skin.
What is the integumentary system?The integumentary system can be described as the set of organs forming the outermost layer of the body. It contains the skin which acts as a physical barrier between the external environment and the internal environment to protect and maintain the body.
The integumentary system involves hair, scales, hooves, feathers, and nails. It may serve to maintain water balance, protect the deeper tissues, excrete wastes, and maintain body temperature, and is the attachment site for sensory receptors which notice pain, sensation, and temperature.
The skin can be defined as one of the largest organs of the body and about 12 to 15 % of total body weight and covers 1.5 to 2m² of surface area. The skin can be described as a composite organ, composed of at least two layers of tissue: the epidermis and the dermis.
