Answers

Answer 1

The work that would have been done if a lever would have been used with an effort arm of 12 meters and a load arm of 6 meters is 50 J.

option A is the correct answer.

What is the work done by the lever?

A lever is a simple machine that makes work easier and faster. When a lever is used, a small effort will be used to overcome a large load.

The efficiency of a machine increases when the output force is greater than the input force.

Mathematically, the formula for the efficiency of a machine is given as;

Eff = ( output force / input force ) x 100 %

The output force is given by the following formula;

F ( out ) = load x distance moved by load

The input force is given by the following formula;

F ( input ) = effort x distance moved by effort

The work that would have been done if a lever would have been used with an effort arm of 12 meters and a load arm of 6 meters is calculated as;

work = ( 600   x 6  ) / ( 12  x 6  )

work = 50 J

Each of five satellites makes a circular orbit about an object that is much more massive than any of the satellites. The mass and orbital radius of each satellite are given below. Which satellite has the greatest speed? Mass Radius (A) ½m R (B) m ½R (C) m R (D) m

Answers

Correct option is B, satellite that has the greatest speed has Mass Radius m ½R.

Because the satellite orbits the earth, the gravitational pull of the planet on the satellite supplies the necessary centrifugal force. In a circular orbit, the gravitational force is constant, hence the satellite's velocity is also constant.

Kepler's third law informs us that

V² = GM/R

Therefore, v = (GM/R)

Where;

V is the speed

G stands for gravity constant.

Mass is M.

R is radius

Let's begin by examining the first choice, which is Option B.

Here, mass equals m and radius equals (1/2)R.

Consequently, v = (Gm/(R/2)) = (2Gm/R)

A standing wave is set up in a pipe with both ends open. The frequency of its first harmonic is 300 Hz. What is the length of the pipe? Take the speed of sound to be 340 m s–1. Give your answer in meters

Answers

When the frequency of a standing wave set up in a pipe (with both ends open) first harmonic is 300 Hz, the length of pipe is 0.567 metres.

Therefore the answer is 0.567 m.

The speed of sound in air is approximately 340 m/s, and the wavelength of the first harmonic of a standing wave in an open pipe is twice the length of the pipe. Therefore, if the frequency of the first harmonic is 300 Hz, the wavelength can be calculated as:

wavelength = speed of sound / frequency

wavelength = (340 m/s) / (300 Hz)

The length of the pipe can be calculated as half the wavelength:

L = wavelength/2

L = (340 m/s) / (2×300 Hz)

L ≈ 0.567 m

So the length of the pipe is 0.68 m

Answers

The new velocity of the object after the event is 7.99m/s.

We are given that,

Mass = m = 50kg

Initial velocity = v = 11.2m/s

Energy = E = 1539j

The kinetic energy of object can be calculated as,

K= (1/2)mv²

K = (50×125.44)/2

K = 3136J

Consequently, since both the initial kinetic energy and the total amount of energy transferred are known. The article's resulting energy is easily discernible.

Final energy = initial kinetic energy - the ending energy

Final energy  = 3136-1539= 1597 joules

Therefore, using the equation for kinetic energy derivation, the speed of the object can now be determined.

K.E = 1/2MV²

1597 = 50/2V²

The Hertzsprung-Russell (H-R) Diagram is a graph that plots the luminosity (or absolute brightness) of stars against their surface temperature (or spectral type). It is used to classify stars based on their properties and understand their evolution.

The following statements are true based on the H-R diagram:

Most stars are located on the main sequence, which runs from the upper left to the lower right of the diagram. This represents stars that are burning hydrogen in their cores and are in a state of equilibrium.

Stars located in the upper right corner of the diagram are brighter and hotter than those on the main sequence and are known as "giants" or "supergiants". They have exhausted the hydrogen in their cores and are in a later stage of their evolution.

Stars located in the lower left corner of the diagram are cooler and less bright than those on the main sequence and are known as "dwarfs". These stars are in the early stages of their evolution and are still burning hydrogen in their cores.

Stars located on the horizontal branch are burning helium in their cores, this represents stars that are in a different stage of their evolution.

There is a clear relationship between a star's luminosity and its temperature, with hotter stars being brighter than cooler stars.

The diagram shows that there is a wide range of luminosities and temperatures among stars, with some being much brighter and hotter than others.

Suppose van Gennip erosses the finish line at her average speed and takes a huge bouquet of flowers handed to her by a fan. As a result, her speed drops to 10.01 m/s. If van Gennip's mass is 63.0 kg, what is the mass of the bouquet

Answers

The mass of the bouquet can be calculated using the equation m = F/a. Which is equal to 0.9kg.

Since van Gennip’s speed dropped from 10.8 m/s to 10.01 m/s after she took the bouquet, this indicates that a force was applied to her causing her to slow down.

The applied force can be determined by taking the difference between her final and initial momentum, which is p = mv.

Thus, the applied force can be calculated by F = Δp/Δt.

Plugging in the given values, the mass of the bouquet can be calculated as

m = F/a = (63.0 kg × (10.8 m/s - 10.01 m/s))/10.01 m/s² = 0.9 kg.

Therefore, the mass of the bouquet is 0.9 kg.

The ball requires a total of zero work to go to the right at 24 m/s.

Take into account the ball's kinetic energy.

Vi = -24 ms-1 for the initial velocity

Final velocity: vf = +24ms⁻¹

K = 12mvf²- 12mvi² = 12m(vf² - vi²) = 12m(242 - 242) = 0,

Two pendulums have the same dimensions (length L) and total mass 1m2. Pendulum A is a very small ball swinging at the end of a uniform massless bar. In pendulum B, half the mass is in the ball and half is in the uniform bar. Find the period of each pendulum for small oscillations. Which one takes longer for a swing

Answers

For pendulum A, the period of oscillation is T = 2π × √(L/g). For pendulum B, the period of oscillation is T = 2π × √(2L/g). As we can see from the formula, Pendulum B takes longer for a swing as its period of oscillation is longer than pendulum A due to the fact that half the mass is distributed along the uniform bar.

The period of a pendulum is given by the formula T = 2π × √(L/g) where L is the length of the pendulum and g is the acceleration due to gravity.

For pendulum A, the total mass is concentrated in the small ball at the end of the massless bar, so the period of oscillation is T = 2π × √(L/g)

For pendulum B, half the mass is in the small ball, and half is distributed along the uniform bar, so the period of oscillation will be T = 2π × √(2L/g)

In both cases, the length of the pendulum is the same, so the period of oscillation for pendulum A is shorter than the period of oscillation for pendulum B. Therefore pendulum B takes longer to swing.

It's worth noting that these calculations are based on small oscillations, when the angle of oscillation is small, as the period of a pendulum is dependent on the angle of oscillation.

How do you calculate lever arm in torque?

Answers

We can find the torque of lever arm by the formula Torque(T)=Force * perpendicular distance.

A torque is an action that causes objects to rotate. A torque is required to rotate an object, just as a force is required to move an object in a line. Torque is created by force, but it also depends on where the force is applied and the point about which the object rotates.

Force and lever arm are not always perpendicular. When the force and lever arm are not perpendicular, trigonometry is required to calculate the length of the lever arm. The force applied is perpendicular to the surface of the object rotating. When this force is at an angle θ with the plane of the object, the perpendicular force requires the use of the sine function.

When an object is in rotational equilibrium, the net torque applied to it is zero.
