The mass would gain twice the kinetic energy it did in the scenario above if the spring were compressed by 14.1 cm.
Do you mean by kinetic energy?A particle or perhaps an item that is currently motion has a type of energy called kinetic energy. An item acquires kinetic energy when work, which involves the transmission of energy, is performed on it by exerting a net force.
A spring's energy reserve is proportional to the square of the compression, x.
PE of compression = 0.5kx^2 where k is a constant to do with how easy it is to compress the spring.
So 0.5d^2 gives a KE of value Q
If you double Q you get 2Q and get 0.5D^2 where D is the new compression
So 0.5d^2/0.5D^2 = Q/2Q
d^2/D^2 = 1/2 which means that D^2 = 2d^2 or D = d(sqrt2)
Therefore, the new compression is roughly 1.414 times that of the old one.
Easiest method for recalling is that KE is proportional to sqrt(d)
To double KE you need to compress the spring sqrt2 times as much as before.
Hope this helps.
PE of spring = stored energy = (1/2)kx^2 = (1.2)mv^2
So kx^2 = mv^2
x^2 = (m/k)v^2
x is proportional to v
If x is doubled, v is doubled, and the KE is quadrupled.
the distance would then be ? 2*d or 1.41d = 1.41(10) = 14.1 cm

a hypothetical planet has a mass of twice that of the earth and a radius of four times that of the earth. what is the acceleration due to gravity on the planet in terms of g, the acceleration due to gravity at the earth?
The acceleration due to gravity on the planet will be 8g.
What is gravity?Gravity is the force of attraction between objects that is exerted by the masses of those objects. It is the weakest of the four fundamental forces in nature and is most noticeable when two objects of significant mass interact. On Earth, gravity is what keeps us firmly rooted to the ground and is what causes objects to fall when we drop them. It is also what causes the moon to orbit around the Earth and the planets to orbit around the sun.
This is because the acceleration due to gravity is directly proportional to the mass of a body and inversely proportional to the square of its radius. This means that if the mass of a body is doubled and its radius is quadrupled, the acceleration due to gravity will be 8 times the acceleration due to gravity at the Earth.

a solid sphere, a solid cylinder, and a hollow cylinder are placed at the top of an inclined plane. if all are made of the same material and are released at the same time, which one will reach the bottom first? group of answer choices the solid cylinder. the sphere. the hollow cylinder.
The solid sphere will reach the bottom of the inclined plane first. The reason for this is that the sphere has the smallest surface area to volume ratio which means that there is less friction acting on it as it rolls down the incline.
Which moves more quickly, a sphere or a cylinder?Solid sphere moves more quickly than solid cylinder because it has a lower moment of inertia and more kinetic energy during translation. Comparable solid objects move more slowly than hollow ones.
Which reaches the bottom first, the cylinder or the sphere?If a cylinder and a sphere have the same mass and radius, the cylinder will have a greater moment of inertia due to its greater mass at its edges. Because the sphere's moment of inertia is smaller, it will move faster and arrive at the bottom first.
What causes a hollow cylinder to roll more slowly?The process by which potential energy (PE) is transformed into kinetic energy is the cause of the solid cylinder's faster descent than the hollow cylinder.

an aluminum cube with side length of 10 cm is divided into two equal pieces so that a hemi-spherical recess with diameter of 8 cm can be bored out of each of the two pieces. if the density of aluminum is 2.7 grams per cubic cm, what is the mass of the remaining metal of the two parts of the cube, to the nearest gram? (density is mass divided by volume.)
The total mass of the remaining metal of the two parts of the cube is approximately 3966 g to the nearest gram.
What is mass?The amount of matter in an object is indicated by its mass. It is typically expressed in grams, kilograms, and tonnes when using the metric system. Mass and Weight are different from one another.
The cube has a volume of 10cm x 10cm x 10cm = 1000 cm^3.
The hemi-spherical recess has a radius of 4cm, so the volume of the recess is (2/3)π(4cm) ^3 = 268.08 cm^3.
The volume of the remaining metal of each piece of the cube is (1000 cm^3 - 268.08 cm^3) = 731.92 cm^3.
So, the mass of the remaining metal of each piece is (density of aluminum) x (volume of remaining metal) = 2.7 g/cm^3 x 731.92 cm^3 = 1983.024 g.
Therefore, the total mass of the remaining metal of the two parts of the cube is 1983.024 g x 2 = 3966.048 g, which is approximately 3966 g to the nearest gram.

determine the minimum speed necessary for a roller coaster car to pass the top of a 12 m radius loop without falling.
The centripetal acceleration must be equal to and in opposition to gravity in order for there to be a net force of zero g's at the top of the loop. the minimum speed required for a roller coaster car is 10.844m/s.
V²/12m = 9.8 m/s²
V = √(12)(9.8) m/s =10.844 m/s.
Acceleration is the rate at which velocity changes with time in terms of both speed and direction. A straight-line moving point or object is accelerated if it speeds up or slows down. Motion on a circle is accelerated even if the speed is constant because the direction is constantly changing. For all other types of motion, both effects contribute to acceleration.
Because acceleration has both a magnitude and a direction, it is a vector quantity. Velocity is also a vector quantity. Acceleration is defined as the change in the velocity vector over a time interval divided by the time interval. The limit of the ratio of the change in velocity gives the instantaneous acceleration (at a specific moment and location).

The volume of a block of aluminum that has the same mass as a block of iron would be 26.23 ccs.
To find the volume of a block of aluminum that has the same mass as a block of iron, we need to use the formula:
Density = Mass/Volume
Given that the density of aluminum is 2.70 g/cc, we can find the volume by rearranging the formula:
Volume = Mass/Density
Since the mass of the block of iron is 70.83 g, we can substitute this into the formula:
Volume = 70.83 g / 2.70 g/cc = 26.23 cc
So the volume of a block of aluminum that has the same mass as the block of iron would be 26.23 ccs.

an uneven arrangment of electrons and protons on a circular arc of radius with angles what are the magnitude and direction of the net electric field produced at the center of the axis
Without more information on the specific arrangement of electrons and protons, it is not possible to determine the magnitude and direction of the net electric field produced at the center of the axis. The electric field is determined by the distribution of charges and their relative positions.
What is an electric field?
An electric field is a force field that surrounds an electric charge, which exerts a force on other charges within the field. The strength of the electric field is represented by the electric field strength (E) and is measured in units of newtons per coulomb (N/C). The direction of the electric field is defined as the direction that a positive test charge would be pushed or pulled if placed in the field. The magnitude of the electric field at any point in space is defined as the force experienced per unit charge, at that point. Electric fields can be created by a variety of sources, including stationary charges, moving charges, and changing magnetic fields.

question the work that must be done by an external agent to move a point charge of 2 mc from the origin to a point 3 m away is 5 j. what is the potential difference between the two points?
1.5 × 10³V is the potential difference between the two points where work done by external agent to move a point charge of 2 mc from the origin to a point 3 m away is 5 J.
What is potential difference?The quantity of current times the resistance equals the potential difference (also known as voltage), which is equal to that. When a charge travels between two locations in a circuit, a potential difference of one Volt is equivalent to one Joule of energy being used by that charge.
W = 5J, the amount of work required to move the point charge by the external agent.
q = 2 mC, is the point charge.
Description of the work is,
W = Vq
V=W/q
Replace the values listed,
V = 5J / 2mC
V = 5J / 2 × 10 ⁻³C
V = 2.5 × 10³ V
Consequently, the possible discrepancy between the points is 1.5 × 10³V
