The elasticity of the balloon's material keeps the 1particles from forcing it to expand. The material stretches as the gas particles bump against the sides, allowing the balloon to expand to a certain point before contracting again.

The elasticity of the balloon's material is an important factor in determining the balloon's shape and size. In general, the more elastic the material is, the more the balloon will be able to stretch and expand. When the material is not elastic enough, it will not be able to stretch and the balloon will remain in its original shape.

The elasticity of the material also affects the amount of air pressure within the balloon. A more elastic material will be able to hold more air pressure, while a less elastic material will not be able to hold as much pressure. This is why balloons with a higher pressure will usually be larger than balloons with a lower pressure.

The mass of the twig can be calculated using the law of conservation of momentum.

The Law of Conservation states that matter and energy cannot be created or destroyed, only changed from one form to another. This law is one of the most fundamental laws of physics, and it applies to all forms of energy, including heat, light, and electrical energy. This law helps explain why energy is always conserved, meaning that it can never be lost, only transferred or converted into another form. This law is also important in understanding the behavior of matter, as it explains why matter can never be completely destroyed, only rearranged or changed in form.

Momentum is equal to the mass times the velocity, so the total momentum of the twig and the snail before the snail starts moving is zero. After the snail starts moving, the momentum of the twig and the snail is equal to the snail's momentum, which is equal to 2.5 g x 1.2 cm/s = 3.0 g cm/s. Since the velocity of the twig is 0.4 cm/s, the mass of the twig must be equal to 3.0 g cm/s / 0.4 cm/s = 7.5 g.

The variation with time of the kinetic energy E_k of the ball is that it decreases. This is because gravity is acting against the ball and slowing it down, so the kinetic energy is decreasing as the ball slows down.

When the ball is released, the initial kinetic energy, E_k, is given by the equation: E_k = mgh, where m is the mass of the ball, g is the gravitational acceleration, and h is the initial height of the ball. As the ball rises, its height increases, and the potential energy, U, increases. However, this increase in potential energy is at the expense of kinetic energy, so the kinetic energy decreases as the ball rises.  

When the ball reaches its maximum height, its kinetic energy is zero as it is at rest. As the ball then begins to fall, its potential energy decreases, and its kinetic energy increases. This is because the ball is falling under the action of gravity, and thus its kinetic energy increases as it accelerates downwards.  Overall, the kinetic energy of the ball decreases as it rises and increases as it falls.

This is due to the conservation of energy, which states that the total energy of a system remains constant. As the potential energy increases, the kinetic energy decreases, and vice versa.

The formula for k in terms of the period T and the mass m in spring constant problem is k = 4π²m/T². The formula applies to a spring-mass system.

A spring-mass system is a system where a mass of object is attached at the free end of the spring. The system will perform a simple harmonic motion where the oscillations occur periodically. The period of any moving object in that motion can be counted as follows

T = 2π√(m/k)

Where

Find the formula for the spring constant k in terms of T and m!

We use the formula above to find k.

T = 2π√(m/k)

√(m/k) = T/2π

m/k = (T/2π)²

m/k = T²/4π²

k = 4π²m/T²

We must first define linear speed in order to respond to the query.

This is the tangential speed of an item moving in a circle. Given by the formula v = r,

r is the object's distance from the circle's center, and is its angular speed.

Given that Julie, Jessica's sister, is riding an inner horse that is placed 6.0 meters from the center of the merry-go-round and Jessica is riding an outside horse that is 8.0 meters away from the center of the ride. The merry-go-round is also rotating at a consistent speed.

Given that v = r and = constant for linear motion,

So, v ∝ r.

Therefore, the girl who was farther away from the merry-go-center round's would move at a faster linear rate.

Since

Julie is at r, and Jessica is at r' = 8.0 m "= 6.0 m.

Acceleration is the rate at which the speed and direction of a moving object vary over time. A point or object going straight ahead is accelerated when it accelerates or decelerates.

When labor is done, energy is transferred from the agent to the object, resulting in a change in the motion of the object (more specifically, a change in the object's kinetic energy).

Energy cannot be generated or destroyed, but it may be moved from one form to another. Energy may be altered in a variety of ways, such as when potential energy becomes kinetic energy or when one thing moves another.

Thermal energy is related to a system's internal energy because of its temperature. When a substance is heated, its temperature rises because its molecules begin to move faster, gaining thermal energy through heat transfer. Conduction, convection, and radiation are the three methods through which thermal energy is transferred.

Answer: Distance = 60 J / 20 N = 3 meters. So the car moved a distance of 3 meters.

Explanation: To determine how far the car moved, you need to know how long the force was applied. The equation for work is work = force * distance, so if you know the force and the work, you can solve for the distance. In this case, you know that the force applied was 20 N and the work done was 60 J, so you can calculate the distance by rearranging the equation to solve for distance: distance = work/force. Plugging in the values, you get distance = 60 J / 20 N = 3 meters. So the car moved a distance of 3 meters.
