If the spring is stretched an additional 0. 130 m and released, how long does it take to reach the (new) equilibrium position again?.

Answers

Answer 1

It will take 1.47 seconds for the mass to reach the new equilibrium position.

A pendulum is in equilibrium when its potential energy equals its kinetic energy. In other words, the kinetic energy is zero and the potential energy is maximum when the pendulum is at rest and the bob is at the lowest point of its arc.

We can use the following equation to calculate the period of oscillation of a mass on a spring:

T = 2π√(m/k)

Where T is the period, m is the mass, and k is the spring constant.

We can use the equation to calculate the spring constant, k, as follows:

k = m/x²

Where x is the initial displacement of the spring.

In this case, m = 1.65 kg and x = 0.270 m.

Therefore, the spring constant, k, is:

k = 1.65/0.27² = 17.59 N/m

We can now use the first equation to calculate the period of oscillation:

T = 2π√(1.65/17.59) = 1.56 s

Since the spring has been stretched an additional 0.130 m, we can calculate the new period of oscillation as follows:

T = 2π√(1.65/19.72) = 1.47 s

Therefore, it will take 1.47 seconds for the mass to reach the new equilibrium position.

the air around a pool and the water in the pool receive equal amounts of energy from the sun. why does the air experience a greater increase in temperature than does the water?

Answers

The air around a pool and the water in the pool absorb the same amount of energy from the sun; however, the water requires more energy to increase its temperature than the air does.

The Differences in Temperature Increase between Air and Water in Response to Solar Energy

Water has a higher specific heat capacity than air, meaning it requires more energy to increase its temperature by the same amount. This is because the molecules in water are more tightly bonded than those in air, so more energy is needed to break these bonds and increase the temperature.

Additionally, water has a higher latent heat of vaporization than air, meaning it requires more energy to evaporate and create steam. Therefore, the air experiences a greater increase in temperature than the water.

what is the direction of the magnetic force on a positive charge that moves as shown? what if the charge was negative?

Answers

For a positive moving charge, the magnetic field is linear. If the charge travelling had been a negative charge, the magnetic field lines would have been oriented in the opposite way.

The magnetic field is also inversely proportional to the velocity of the travelling charge, or B v B v. (in this case the magnetic field is directly proportional to the speed). As a general rule, to determine the direction of the magnetic force acting on a negatively charged particle, first determine the force's direction acting on the positive charge, then reverse that direction to determine the force's direction acting on the matching positive charge. Therefore, in this issue, the force is pointed in the direction of the left. The right hand rule can be used to determine the direction of the magnetic force.

Using Centripetal Force the Number of revolutions per minute is 0.95rpm, such that the Space statition is rotating in circular path

What is Centripetal Force?

A force that causes a body to follow a curved path is known as a centripetal force. It always moves in a direction that is the opposite of the body's velocity and in the direction of the immediate center of curvature of the path. It is "a force by which bodies are dragged or driven, or in any other way gravitate, towards a point as to a center," according to Isaac Newton. Gravity is the centripetal force that drives astronomical orbits according to Newtonian mechanics.

A common illustration of centripetal force is when a body moves uniformly fast in a circular motion. The centripetal force is directed towards the center of the circular route both along the radius and at right angles to the motion.

now coming to given statement,

In order for the station to produce an artificial gravity, its centripetal acceleration must be the same as the gravitational acceleration.

Since the radial acceleration is [tex]a_r[/tex] = g = [tex]\frac{v^2}{r}[/tex]

Answers

The vertical component of the velocity is 19.25 m/s.

The vertical component of the velocity can be determined using the trigonometric function of sine.

The sine of an angle is equal to the ratio of the opposite side to the hypotenuse of a right triangle.

In this case, the angle is 37° and the hypotenuse is the velocity, 25 m/s. We need to find the opposite side, which is the vertical component of the velocity.

We can use the equation for the sine of an angle to solve for this:

sin(37°) = Opposite side/25

We can rearrange this equation to solve for the opposite side:

Opposite side = 25 * sin(37°)

a boat, whose speed in still water is 8.0 m/s, is directed across a river with a current of 6.0 m/s. what is the speed of the boat as it crosses the river?

Answers

The boat is moving at a speed of 2.0 m/s when crossing the river.

Step 1: Determine the boat's velocity in relation to the river by deducting the river's current from the boat's speed in still water.

Boat speed in relation to the river is equal to 8.0 m/s minus 6.0 m/s, or 2.0 m/s.

In Step 2, multiply the boat's angular velocity to the stream by both the lake's current to determine how fast the sailboat will be traveling across the water.

Boat's river crossing speed is calculated as 2.0 m/s plus 6.0 m/s, which equals 8.0 m/s.

Because of this, the boat is moving at 8.0 m/s as it crosses the river.

why do waves become breaking waves in shallow water? select one: a. the base of the wave speeds up compared to the top of the wave. b. wind speed increases closer to shore. c. the base of the wave is slowed by friction with the seafloor, but the top is not. d. winds push on the tops of the waves.

Answers

Because of friction with seafloor, the bottom of the wave slows down more quickly than the top; yet, the top does not.

What generates a friction?

A force known as friction opposes the relative motion of two materials or objects. Molecule adhesion, waviness, and deformations are the underlying factors of this resistive force.

How does friction operate?

When two objects rub against one another, there is a force called friction that prevents either from moving. Friction is the movement of two objects against one another. Friction moves in the opposite direction and opposes motion. The materials the surface are comprised of affect how much friction there is.

f io is the intensity of the light incident on the first polarizer, what is the intensity of the light that passes through the second polarizer whose axis is oriented at an angle of 90 degree

Answers

The second polarizer's axis is positioned at a 90-degree angle, and the light intensity that passes through it is 0.

The incident light is ordinary light. it is unpolarised

I₁=I₀/2  For the first polarized

I₂=I₁cos²θ          (Second polarization)

 =I₀/2 cos²90°             (θ=90)

 =I₀/2(0)²

When an area is measured on a plane perpendicular to the direction of energy propagation, it is possible to define the intensity or flux of radiant energy as the power transferred per unit area. Watts per square meter (W/m2) and kg/s3 are the basic units for this system in the SI. The term "intensity" is most usually used to describe electromagnetic or acoustic waves, such as light or radio waves, where the average power transfer over the course of one wave period is taken into account. Any situation where energy is exchanged can be described as having intensity. The amount of kinetic energy that water drops from a garden sprinkler are carrying, for instance, might be calculated.

What is the wavelength of radiation that has a frequency of 2.10 1014 s?

Answers

The wavelength of radiation is 1.428 x 10⁻⁶m.

The equation E=hf is called the Planck relation or Planck-Einstein relation. The letter h is named after Planck as Planck's constant. Energy (E) is related to this constant h and the frequency (f) of the electromagnetic wave.

In quantum wave theory, the Planck relation describes the shear wave energy emitted or absorbed as an electron transitions between energy levels within an atom. If the atom contains electrons, the destructive wave interference between the protons and electrons in the nucleus gives rise to destructive waves, resulting in binding energy. This binding energy is the energy of a photon emitted when an electron is captured or moves between states within an atom. Electron vibrations generate transverse waves, and photon energy is based on the frequency of that vibration.
