The spring constant of a spring that is compressed 5.0 cm and has 0.325 j of elastic potential energy stored in it is 13 N/cm.
What is the spring constant?
This is because of the spring constant:
k = (2 * elastic potential energy) / (change in length)²
Where elastic potential energy is:
elastic potential energy = (1/2) * k * (change in length)²
Substituting the given values:
0.325 = (1/2) * k * (0.05)²
Simplifying:
0.325 = 0.00125k
Solving for k:
k = 0.325 / 0.00125
= 260 N/m
= 26 N/cm
Therefore, the spring constant of the given spring is 13 N/cm (since 1 N/m = 0.1 N/cm).

which of the following is true about a comet that is on an elliptical orbit around the sun? question 24 options: the comet's speed is greatest when it is farthest from the sun. the comet's speed is greatest when it is nearest the sun this comet's speed is zero. the comet's speed is constant because its mass and the sun's mass stay approximately the same
The following is true about a comet that is on an elliptical orbit around the sun is b. The comet's speed is greatest when it is nearest the sun.
A comet is an object in space with a visible coma or atmosphere, along with a "tail" that can extend for millions of miles through space. A comet's orbit is elliptical or oval-shaped; that is, it is more elliptical or oval-shaped than a planet's or moon's orbit.
As a result, when it approaches the sun, its velocity increases.When the comet is closest to the sun, its speed is greatest. This is due to the fact that as a comet travels closer to the sun, it falls under the sun's gravitational pull, causing its speed to increase. As a result, the comet's velocity at its closest approach to the sun is the highest.

A switch using one electrical circuit to control a second electrical circuit
The region within which magnet force can be detected
1. Relay: A switch using one electrical circuit to control a second electrical circuit
2. Magnetic field: The region within which magnet force can be detected
Relay and Magnetic FieldsA relay is an electrical switch that uses one electrical circuit to control a second circuit. When the first circuit is activated, it closes the second circuit, allowing electricity to flow. This type of switch is commonly used in a variety of applications, such as controlling electric motors, switching between power sources, and providing automated control of lights or other electrical appliances.
A magnetic field is an area around a magnet or electric current where a magnetic force can be detected. Magnetic fields are created by moving electric charges, and the strength and direction of the field is determined by the strength and direction of the charge. Magnetic fields can interact with other magnetic fields, causing them to either attract or repel each other. Magnetic fields are also affected by other materials, such as iron, which can direct and focus the field. Magnetic fields are essential for the functioning of many electronic devices, and can be used to create electric current.

mountain bike tires have large, knob-like treads. these tires are useful on steep slopes because they responses increase friction. increase friction. carry heavy weights. carry heavy weights. increase the stopping distance. increase the stopping distance. prevent braking of the bicycle.
The correct option for the given statement is the first option i.e., they increase friction.
Mountain bike tires have large, knob-like treads. These tires are useful on steep slopes because they increase friction. Friction is a force that opposes motion between two surfaces that are in contact, and this force can be helpful when trying to stop or slow down the bike.
The treads help the tire to grip the surface better, which increases friction and makes it easier to control the bike. Additionally, mountain bike tires are wider than road bike tires, which also increases their contact area with the ground and thus, the friction.
They are also designed to withstand more abuse than road bike tires, as they are meant to handle rougher terrain, so they are less likely to puncture or wear down quickly. Hence, it can be concluded that mountain bike tires are useful on steep slopes because they increase friction.

a 7.0 kg bowling ball moves at 2.20 m/s. how fast must a 2.2 g ping pong ball move so that the two balls have the same kinetic energy
The speed of the 2.2 g ping pong ball must be 3.43 m/s in order for it to have the same kinetic energy as the 7.0 kg bowling ball moving at 2.20 m/s
To calculate the speed of the 2.2 g ping pong ball so that it has the same kinetic energy as the 7.0 kg bowling ball moving at 2.20 m/s, use the equation KE = 1/2 mv2, where m is mass and v is speed.
Rearrange the equation to v = √(2KE/m).
Substituting the given values, we get:
v = √(2 * (1/2 * 7.0kg * 2.20m/s2) / 2.2g)
v = 2.20 m/s
Therefore, the speed of the 2.2 g ping pong ball has the same kinetic energy as the 7.0 kg bowling ball moving at 2.20 m/s.

an unbelted victim in a car accident will continue to move in the same direction and with the same speed until the dashboard causes a change in motion. this best exemplifies
According to Newton's first law, an unbelted victim in a car accident will continue to move in the same direction and with the same speed until the dashboard causes a change in motion.
Inertia is the tendency of an object to remain in motion in the absence of an unbalanced force. It is the property of an object to resist any change in motion unless acted upon by an external force.
The dashboard applies an external force that changes the direction and speed of the victim. This is because the person has no external forces acting on them to cause them to stop. Since they were in motion at the time of the accident, they will continue in that motion unless acted upon by another force, such as the dashboard, until they come to a stop or another force acts upon them.
Therefore, the best exemplifies the law of inertia. The law of inertia states that an object at rest will remain at rest, and an object in motion will remain in motion at a constant velocity unless acted upon by an external unbalanced force.
