which has greater value, a newton of gold on earth or a newton of gold on the moon?

Answers

The moon, because the acceleration due to gravity is less.

One newton of gold on the moon would have a greater value than a newton of gold on earth because the magnitude of the acceleration due to gravity on the moon is smaller than the gravity on the earth .

What is gravity ?

It can be defined as the force by which a body attracts another body toward its center as the result of the gravitational pull of one body and another .

As given in the problem, we have to find out which has greater value, a newton of gold on earth or a newton of gold on the moon .

A newton of gold would be worth more on the moon than it would be on earth since the moon experiences a smaller acceleration from gravity than the earth does .

explain how the composition of a star that will form a billon years in the future will differ the composition of our sun.

Answers

Answer:

Explanation:

Basically the star slowly burns its hydrogen into Helium. Depending on the mass, the star will have a turbulent core where the Helium will be fully mixed or a radiative core where the helium will settle at the centre (remember it's heavier than Hydrogen). The second case is what happens in the Sun.

A wooden log has to be carried by two people. If one of them is strong and another weak, how will they carry the log? Show with a diagram and also give reason.​

Answers

Answer:

Unbalanced forces

When two forces acting on an object are not equal in size, we say that they are unbalanced forces. The overall force acting on the object is called the resultant force. If the forces are balanced, the resultant force is zero.

If the forces on an object are unbalanced, this is what happens:

a stationary object starts to move in the direction of the resultant force

a moving object changes speed and/or direction in the direction of the resultant force

In the example below, the resultant force is the difference between the two forces:

100 – 60 = 40 N (to the right)

Using moments

A see-saw will balance if the moments on each side of the pivot are equal. This is why you might have to adjust your position on a see-saw if you are a different weight from the person on the other end.

If a nut is difficult to undo with a short spanner, a longer spanner will help. This is because there will be a bigger moment on the nut, when the same force is applied further from the pivot.

Using the same principle you can increase the moment applied by a lever or a crowbar, and this can help you move heavy objects more easily.

two pendula are released from rest at the same height h above their lowest points. how do the maximum velocities of the two pendulums compare? note that pendulum 2 has a string with length twice that of pendulum 1.

Answers

The simple pendulum concept and rotational kinematics relationships allow finding the result for the velocity relationship

 The shortest pendulum (w₁) has more speed than the longest pendulum (w₂)

               w₁ = [tex]\sqrt{2}[/tex]  w₂

 

The simple harmonic movement is a periodic movement where the restoring force is proportional to the elongation, in the case of the simple pendulum it is fulfilled for angles less than 10º.  The expression for motion is

          θ  = θ₀ cos ωt

         ω² = g / l

the angular velocity is defined by

         w = [tex]\frac{d \theta}{dt}[/tex]  

         w = - θ₀ ω sin ωt

Where θ₀ is the initial angle or amplitude, w is the angular velocity, t the time, g the acceleration of gravity and l the length of the pendulum

Let's find the angular velocity for each pendulum

          ω ₁ = [tex]\sqrt{ \frac{g}{l_1} }[/tex]

Indicate that the second pendulum length is

          l₂ = 2 l₁

         ω₂ = [tex]\sqrt{\frac{g}{2l_1} }[/tex]  

the pendulum speed is maximum at the lowest point of the trajectory that occurs when the sine function has its maximum value

          w =  θ₀ω  

Suppose that the two pendulums are released with the same initial angle

         

Pendulum 1

          w₁ =  θ₀ [tex]\sqrt{\frac{g}{l_1} }[/tex]

Pendulum 2

          w₂ = θ₀  [tex]\sqrt{\frac{g}{2l_1} }[/tex]

We look for the relationship between the two speeds

           [tex]\frac{w_1}{w_2} = \sqrt{2}[/tex]  

In conclusion, using the simple pendulum concept and the rotational kinematics relations we can find the result for the velocity relation

 

The shortest pendulum (w₁) has more speed than the longest pendulum (w₂)

             w₁ = √2 w₂

2.) Explain why the starting angle doesnt impact the time it takes the pendulum to swing back and forth?​

Answers

The starting angle θθ of a pendulum does not affect its period for θ<<1θ<<1. At higher angles, however, the period TT increases with increasing θθ.

The relation between TT and θθ can be derived by solving the equation of motion of the simple pendulum (from F=ma)

−gsinθ=lθ¨−gain⁡θ=lθ¨

For small angles, θ≪1,θ≪1, and hence sinθ≈θsin⁡θ≈θ. Hence,

θ¨=−glθθ¨=−glθ

This second-order differential equation can be solved to get θ=θ0cos(ωt),ω=gl−−√θ=θ0cos⁡(ωt),ω=gl. The period is thus T=2πω=2πlg−−√T=2πω=2πlg, which is independent of the starting angle θ0θ0.

For large angles, however, the above derivation is invalid. Without going into the derivation, the general expression of the period is T=2πlg−−√(1+θ2016+...)T=2πlg(1+θ0216+...). At large angles, the θ2016θ0216 term starts to grow big and cause

The photoelectric effect is a phenomenon in which electrons are ejected from the surface of a metal when light is incident on it. These ejected electrons are called photoelectrons. It is important to note that the emission of photoelectrons and the kinetic energy of the ejected photoelectrons is dependent on the frequency of the light that is incident on the metal’s surface.

Answer:

Photoelectric effect is the phenomenon in which electrically charged particles are released from or within a material when it absorbs electromagnetic radiation. The effect is often defined as the ejection of electrons from a metal plate when light falls on it.

Explanation:

A lamp is labelled '230 V, 100 W'. How many joules of electrical energy is changed to thermal energy and light if the lamp is switched on for 2 hours?

Answers

Given;

V = 230V

Power, P = 100W

time, t = 2hrs = 7200s

from,

P = IV

and Energy, E= Pt

E = 100*7200

E = 720000 Joules

E = 720KJ

Answer:

Formula  E(J) = P(W) × t(s)

3600 Seconds in an hour

7200 seconds in two hours.

watts = 100

100 x 7200 = 720000

Explanation:

Watts to joules calculation

The energy E in joules (J) is equal to the power P in watts (W), times the time period t in seconds (s):

E(J) = P(W) × t(s)

Energy cannot be created or destroyed, only converted from one form to another. These conversions can be shown in Sankey diagrams. Efficiency is a measure of how much useful energy is converted. Attachment 1

Modern energy-saving lamps and LEDs (light-emitting diodes) work in a different way. They transfer a greater proportion of electrical energy as light energy. Attachment 2

From the diagram, you can see that much less electrical energy is transferred, or 'wasted', as heat energy from the energy-saving lamp. It's more efficient than the filament lamp.

Calculating efficiency

The efficiency of a device, such as a lamp, can be calculated:

efficiency = useful energy out ÷ total energy in (for a decimal efficiency)

or

efficiency = (useful energy out ÷ total energy in) × 100 (for a percentage efficiency)

The efficiency of the filament lamp is 10 ÷ 100 = 0.10 (or 10%). This means that 10 per cent of the electrical energy supplied is transferred as light energy (90 per cent is transferred as heat energy).

The efficiency of the energy-saving lamp is 75 ÷ 100 = 0.75 (or 75 per cent). This means that 75 per cent of the electrical energy supplied is transferred as light energy (25 per cent is transferred as heat energy).

Note that the efficiency of a device will always be less than 100 per cent. Occasionally the power is shown in W instead of the energy in J. The equations are the same – just substitute power for energy:

efficiency = useful power out ÷ total power in (for a decimal efficiency)

or

efficiency = (useful power out ÷ total power in) × 100 (for a percentage efficiency)

This is the Sankey diagram for a typical energy-saving lamp:

is sliding or static friction greater in magnitude?

Answers

Answer: static friction

Explanation:

During sliding, contact points do not get enough time to get interlocked properly. Therefore, less friction. But, when the object is at rest, the surfaces interlock well, therefore friction is more. This explains why sliding friction is less than static friction.
