A way the balls behave the same way is by bouncing about 1 time after throwing the balls up. A way the balls act differently is the blue ball is bouncier than all the balls, the red ball bounces about 2 times before stopping, and the green ball doesn’t really bounce except for one time.
Explanation:
you also can use paraphrase to help you reword bye bye!!
My Answer:
Starting with how they acted the same. All three balls fell at the same rate since they are of the same mass; gravity has equal force on all three. Next to the differences, all three balls bounce differently. The blue ball had an average of four bounces before it stopped. The red ball bounced twice before stopping, and lastly, the green ball didn't bounce.

When work is done by the force of gravity, the path that the object takes isn't important. What matters
is the object's change in height, regardless of the path taken to get there. We have already discussed
that when there is a net force on an object, it's kinetic energy changes. We can see that in the
previous example of the brick falling towards the Earth over a distance h. As it falls the net force on it
is F,-mg, and it gains kinetic energy as it falls. Let's consider what must happen before the brick
falls. If the brick starts on the ground, let's assume that someone has to lift it up a distance h before it
falls.
10) If you lift a brick (mass m) up a distance h, what is the minimum force you need to apply to the
brick to lift it up?
11) If you apply that much force to the brick, how much work does your force do on the brick over the
distance h?
12) While lifting the brick, what is the net force acting on the brick?
13) While you are lifting up the brick, the net force on it is zero. Therefore, the net work done on the
brick is zero, and its kinetic energy remains the same. However, your force is still doing work on
the brick. If it's not causing a gain of kinetic energy then what is that work doing?

When light traveling in straight lines passes through an object that is curved like a lens, the light is ________ at different angles.
Answer:
You are right. It is reflected
Explanation:
if it is concave then the light is reflected at one direction.
if it is convex the light is reflected outwards and they will travel away from the focal point and the light scatters or will be reflected to different directions
When light traveling in straight lines passes through an object that is curved like a lens, the light is refracted at different angles. Thus, the correct option is B.
What is refraction of light?Refraction is the phenomena of bending of light, it also happens with sound, water and other waves as it passes from one transparent substance into another substance. This bending of light by refraction makes it possible for us to have lenses, such as magnifying glasses, prisms, and rainbows.
When a ray of light travels in straight line, it passes through an object that is curved like a lens, the light is refracted at various different angles, depending upon the angle of incidence of light on the lens.

A 100 kg block slides down a frictionless ramp which is at an angle of 26.6 ∘ with the horizontal. Find the magnitude of the velocity of the block when it gets to the bottom of the ramp if the length of the incline is 50 meters. V=_____m/s
The block accelerates down the ramp due to the component of its weight that acts parallel to the ramp; this force has magnitude
(100 kg) g sin(26.6°) ≈ 438 N
(Note that the positive sign here means we take "down the ramp" to be the positive direction.)
Since the ramp is frictionless, this is the only force acting on the block in this direction. By Newton's second law, the block's acceleration is a such that
438 N ≈ (100 kg) a ⇒ a ≈ 4.38 m/s²
The block accelerates uniformly, so that it attains a speed v as it moves 50 m such that
v² = 2a (50 m)

Two charged particles with opposite signs but the same magnitude of charge enter a magnetic field that is perpendicular to their direction of motion. How will the motion of the two particles differ when they enter the magnetic field?
Answer:
the two particles will go opposite directions, along clockwise circle and counter-clockwise circle, respectively.
Explanation:
charge = ±q, velocity = v, magnetic field = B
force F = q v x B
opposite q will give opposite force, so the two particles will go opposite directions, along clockwise circle and counter-clockwise circle, respectively.

The complete statement is -
"A raised object has energy in its gravitational potential energy".
What is gravitational potential energy? Gravitational energy or gravitational potential energy is the potential energy a massive object has in relation to another massive object due to gravity. It is the potential energy associated with the gravitational field, which is released (converted into kinetic energy) when the objects fall towards each other. Gravitational potential energy increases when two objects are brought further apart.For two pairwise interacting point particles, the gravitational potential energy {U} is given by -[tex]${\displaystyle U=-{\frac {GMm}{R}}}[/tex]
Close to the Earth's surface, the gravitational field is approximately constant, and the gravitational potential energy of an object reduces to -U = mgh
The force between a point mass {M} and another point mass {m} is given by Newton's law of gravitation -[tex]${\displaystyle F={\frac {GMm}{r^{2}}}}[/tex]
To get the total work done by an external force to bring point mass
{m} from infinity to the final distance {R} (for example the radius of
Earth) of the two mass points, the force is integrated with respect to
displacement -
[tex]${\displaystyle W=\int _{\infty }^{R}{\frac {GMm}{r^{2}}}dr=-\left.{\frac {GMm}{r}}\right|_{\infty }^{R}}[/tex]

- Finding food and knowing whether it is acceptable and safe to eat.
- Making sure that you are in a safe area that is okay for you to camp out in.
- Making sure that you have some sort of protection, whether that would be with a weapon, a tool, or something else.
- Making sure that you have safe water to drink that you brought with you.
- A back-up plan in case there is a reason that you need to leave.
- A first aid kit in case of injury.
- How to create a fire and use it safely.
- A way to get back home, with a plan and possibly even a compass.

The total work done is equal to 134 J.
Work
The work formula is characterized as the multiplication of the force performed and the distance in which the movement was performed, so that:
[tex]W = F \times d[/tex]
Thus, it is enough to calculate the value of the work in each movement and add to find the total work, so that:
[tex]W_1 = 3 \times 28 = 84J\\W_2= 4 \times 14 = 56J\\W_3 = (-1.2) \times 5 = 6J[/tex]

6 J of work is needed to stretch a spring from 10 cm to 12 cm and another 10 J is needed to stretch it from 12 cm to 14 cm, what is the natural length of the spring (in centimeters)
Answer:
9.8 cm
Explanation:
x = natural length
k*[(12 - x)² - (10 - x)²]/2 = 6 (1)
k*[(14 - x)² - (12 - x)²]/2 = 6 + 10 (2)
(1): k(144 + x² - 24x - 100 - x² + 20x) = 12
k(44 - 4x) = 12,
divide by 4, k(11 - x) = 3, k = 3/(11 - x)
(2): k(196 + x² - 28x - 144 - x² + 24x) = 32
k(52 - 4x) = 32
divide by 4, k(13 - x) = 8
3/(11 - x) * (13 - x) = 8
3(13 - x) = 8(11 - x)
39 - 3x = 88 - 8x
5x = 49
x = 9.8 cm

A box of weight 100 N is at rest on a floor where μs = 0.4. A rope is attached to the box and pulled horizontally with tension T = 30 N. Which way does the box move?
∑F = F-fs
∑F = F - μs.N
∑F = 30 - 0.4 x 100
ΣF = 30 - 40 = -10
the box doesn't move
Due to the fact that the tension of 30 N that is given to the rope is less than the maximum static friction force of 40 N, the box remains in its current position.
We need to make a comparison between the force of static friction and the force that was applied in order to figure out which way the box is going to move. The static friction force (F[tex]_friction[/tex]) works in the opposite direction to the applied force, and it keeps the box from moving so long as the applied force does not exceed the maximum static friction force. This is true provided that the applied force does not exceed the maximum static friction force.
The following equation can be used to derive the greatest static friction force (F[tex]_friction_max[/tex]) that exists between the box and the floor:
F[tex]_friction_max[/tex] = s multiplied by N
where s is the coefficient of static friction and N is the normal force. Because the box is sitting still on the floor, the normal force is equal to the weight of the box, which is 100 N in this example.
F[tex]_friction_max[/tex] equals 0.4 times 100 N, which equals 40 N.
The tension in the rope, measured in newtons (N), is thirty. Due to the fact that T (30 N) is less than the maximum force of static friction (40 N), the box will not be able to overcome the static friction, and it will not move in the direction where the applied force is exerting its force.
Therefore, there is no movement of the box when a strain of 30 N is applied to the rope and it is pulled.
