TRUE OR FALSE: waves do not carry mass
Answer:
The water itself has mass, but the wave has no mass. ... In this way, waves can have no mass but still carry momentum. In addition to being a particle, light is also a wave. This allows it to carry momentum, and therefore energy, without having mass
Answer:
True

Does a wooden or plastic ruler have more elastic energy?
A wooden ruler is likely to have more elastic energy than a plastic ruler.
What is elastic energy?The elastic potential energy of an object is proportional to its elasticity, which in turn is related to its Young modulus. Young's modulus is a measure of how much a material will deform under a given amount of stress.
When a ruler is bent, elastic potential energy is stored in the material. When the ruler is released, the stored energy is released and the ruler returns to its original shape.
Compared to plastic, wood is generally stiffer and less elastic, which means it has a higher Young's modulus. This means that a wooden ruler can store more elastic potential energy than a plastic ruler when bent by the same amount.
Thus, A wooden ruler is likely to have more elastic energy than a plastic ruler.

What is the force that acts upon a rollercoaster after it reaches the top of the hill?
A. Kinetic energy
B. Mass
C. Potential energy
D. Gravity
Answer:
its d which is gravity
Explanation:
Potential energy is the force that acts upon a rollercoaster after it reaches the top of the hill. Thus, the correct option is C.
What is Potential energy?Potential energy is the energy which is stored in an object due to its position or configuration in the environment. In other words, potential energy of an object refers to the energy which an object holds due to its position relative to the other objects in the system, stresses within itself, its electric charge, or other factors as well.
Potential energy is the energy which is stored in the body of an object which is at rest. The SI unit of Potential energy is Joules (J). The potential energy of an object can be calculated as the product of mass of the object, acceleration due to gravity, and height of the object.
Therefore, the correct option is C.

Which change will always result in an increase in the gravitational force between two objects?
increasing the masses of the objects and increasing the distance between the objects
O decreasing the masses of the objects and decreasing the distance between the objects
Som
SUreasing the masses of the objects and decreasing the distance between the objects
decreasing the masses of the objects and increasing the distance between the objects
Ο Ο Ο Ο
Answer:
Increasing the mass and decreasing the distance between the two objects.
Explanation:
An increase in mass will cause them to have a stronger pull or gravity. A decrease of distance will make it easier for the objects to fall into each other because they would be further into the other objects area of influence.

A 10 kg block is pulled across a table by a force of 42 N with an opposing force of 6 N due to friction. What is the acceleration of the block?
Given:
M=10KG
F=42N
Opposing Force=6N
If we can recall F=ma, we can easily calculate the acceleration by substituting the given variables; but in our case, we have an opposing force. So we have to subtract the opposing force from the horizontal force.
F = ma
42N-8N=10KG x a
34N = 5KG x a; divide both sides by 10KG for a to be sole variable
34kg m/s^2) / 10kg x a (Newtons are sometimes referred to as kg m/s^2)
3.4 m/s^2 = a ; (kg's are cancelled)
Therefor, our acceleration is 3.4 m/s^2.
Identify how Newton's third law of motion was responsible for the astronaut's return to the space station.
Plz I'll give brainlist
Answer:
Rockets traveling through space encompass all three of Newton's laws of motion. When the engines fire and propel the rocket forward, it is the result of a reaction. The engine burns fuel, which is accelerated toward the rear of the ship. This causes a force in the opposite direction to push the rocket forward

Your teacher gives you a mystery species to investigate. She wants you to determine the mystery species’ kingdom. She gives you the following clues:
● The mystery species can perform photosynthesis.
● The mystery species is multicellular.
● The mystery species has a cell wall.
After receiving the clues you start to eliminate the kingdoms into which you know your species does not belong. Which of the following explanations is accurate?
A.
I can eliminate both bacteria kingdoms because bacteria are multicellular.
B.
I can eliminate the animal kingdom because all animals are unicellular.
C.
I can eliminate the animal kingdom because animals do not have cell walls.
D.
I can eliminate the animal kingdom because they have cell walls but cannot perform photosynthesis.
I can eliminate the animal kingdom because animals do not have cell walls. So, the correct option is C.
It is given that the mystery species can perform photosynthesis, they are multicellular and also the mystery species has a cell wall.
The only kingdom of species that does not have a cell wall is the kingdom animalia. Since, the function of cell wall is to provide rigidity and reduces the flexibility of cells, they are not present in animals. The presence of cell wall in animals will make them less flexible and affects their free movement. So, I can eliminate the animal kingdom from the mystery species.

CALCULATE: find the velocity of a wave in a wave pool if it's wavelength is 3.2 m and its frequency is 0.60 Hz
1. V = 1.29 m/s
2. V = 1.3 m/s
3. V = 1.92 m/s
The velocity of a wave in a wave pool if it's wavelength is 3.2 m and its frequency is 0.60 Hz V = 1.3 m/s.
What is Velocity?
Velocity is defined as a vector measurement of the rate and direction of motion. Velocity is the speed at which something moves in one direction.
The speed of a car traveling north on a major freeway and the speed a rocket launching into space can both be measured using velocity.
As you might have guessed, the scalar (absolute value) magnitude of the velocity vector is the speed of motion. In calculus terms, velocity is the first derivative of position with respect to time.
Therefore, The velocity of a wave in a wave pool if it's wavelength is 3.2 m and its frequency is 0.60 Hz V = 1.3 m/s.

Four boxes are sliding with constant speed before each box experiences and unbalanced force of 8 N. Which box would experience the greatest acceleration when the unbalanced force is applied? Answer choices: A) The box with a mass of 2 g B) The box with a mass of 4g C) The box with a mass of 6 g D)The box with a mass of 8 g
Answer:
d
Explanation:
Acceleration is defined as rate of change of velocity with respect to time.
The box with mass of 2 g experience the greatest acceleration.
Force at any object is defined as product of its mass and acceleration.
That is, [tex]F=ma\\\\a=\frac{F}{m}[/tex]
Where F is force, m is mass and a is acceleration of object.
F = 8 N is given.
Acceleration of the box of 2 g = [tex]\frac{8}{2}=4 m/s^{2}[/tex]
Acceleration of the box of 4 g = [tex]\frac{8}{4}=2m/s^{2}[/tex]
Acceleration of the box of 6 g = [tex]\frac{8}{6}=1.34m/s^{2}[/tex]
Acceleration of the box of 8 g = [tex]\frac{8}{8}=1m/s^{2}[/tex]
Therefore, box with mass of 2 g experience the greatest acceleration.
