A 10 kg bowling ball is lifted from the ground to a height of 1 meter. Assuming the bowling alley is on Earth, which type of potential energy is stored in a ball and why? Class 6

Answer:

[tex]T=2.5*10^{-3}s[/tex]

Explanation:

From the question we are told that:

Beat frequency [tex]F_b=4[/tex]

Frequency [tex]F=400Hz[/tex]

Generally the equation for Frequency of the violin is mathematically given by

 [tex]f_v=F_b+F[/tex]

 [tex]f_v=4+400Hz[/tex]

 [tex]f_v=404Hz[/tex]

Therefore the period of the violin string oscillations is

 [tex]T=\frac{1}{f_v}[/tex]

 [tex]T=\frac{1}{404}[/tex]

 [tex]T=2.5*10^{-3}s[/tex]

Explanation:

We need to apply the conservation law of linear momentum to two dimensions:

Let [tex]p_{1}[/tex] = momentum of the 1st ball

[tex]p_{2}[/tex] = momentum of the 2nd ball

In the x-axis, the conservation law can be written as

[tex](p_{1} \cos \theta_{1})_{i} + (p_{2} \cos \theta_{2})_{i} = (p_{1} \cos \theta_{1})_{f} + (p_{2} \cos \theta_{2})_{f} [/tex]

or

[tex](m_{1}v_{1})_{i}= (m_{1}v_{1}\cos \theta_{1})_{f} + (m_{2}v_{2}\cos \theta_{2})_{f} [/tex]

Since we are dealing with identical balls, all the m terms cancel out so we are left with

[tex](v_{1})_{i} = (v_{1})_{f}\cos \theta_{1} + (v_{2})_{f}\cos \theta_{2}[/tex]

Putting in the numbers, we get

[tex]1.33 = (0.750) \cos(33.30) + (v_{2})_{f} \cos \theta_{2}[/tex]

[tex] = > (v_{2})_{f} \cos \theta_{2} = 0.703[/tex]

In the y-axis, there is no initial y-component of the momentum before the collision so we can write

[tex]0 = (v_{1}\sin \theta_{1})_{f} + (v_{2}\sin \theta_{2})_{f} [/tex]

or

[tex] = > (v_{2})_{f} \sin \theta_{2} = (0.750) \sin(33.30) = 0.412[/tex]

Taking the ratio of the sine equation to the cosine equation, we get

[tex] \frac{ \sin \theta _{2}}{ \cos \theta_{2} } = \tan \theta_{2} = \frac{0.412}{0.703} = 0.586[/tex]

or

[tex] \theta_{2} = { \tan}^{ - 1} (0.586) = 30.4[/tex]

Solving now for [tex](v_{2})_{f}[/tex],

[tex](v_{2})_{f} = \frac{0.412}{ \sin(30.4) } = 0.815 \: \frac{m}{s} [/tex]

Answer:

step down transformer

Explanation:

Applying,

Vp/Vs = Np/Ns................ Equation 1

Where Vp = Primary voltage, Vs = secondary voltage, Np = number of turns in the primary coil, Ns = number of turns in the secondary coil

make Vs the subject of the equation

Vs = VpNs/Np............. Equation 2

From the question,

Given: Vp = 240 V, Np = 8000 turns, Ns = 200 turns

Substitute these values into equation 2

Vs = (240×200)/8000

Vs = 6 V.

Since,

Vp>Vs, the the transformer is a step down transformer

Answer: A shunt is a low-ohm resistor that can be used to measure current. ... The entire current flows through the shunt and generates a voltage drop, which is then is measured. Using Ohm's law and the known resistance, this measurement can then be used to calculate the current (I = V/R).

Answer: 10 V, 40 V

Explanation:

Given

Resistors are [tex]500\Omega[/tex] and [tex]2000\Omega[/tex]

Power supply [tex]V=60\ V[/tex]

Voltmeter internal resistance [tex]r=2000\ \Omega[/tex]

When it connected around [tex]500\Omega[/tex] resistance, effective resistance becomes

[tex]\Rightarrow \dfrac{1}{R}=\dfrac{1}{500}+\dfrac{1}{2000}\\\\\Rightarrow R=\dfrac{2000}{5}\\\\\Rightarrow R=400\ \Omega[/tex]

Total resistance in series [tex]R_{net}=2400\ \Omega[/tex]

Current in circuit

[tex]I=\dfrac{60}{2400}=\dfrac{1}{40}\ A[/tex]

Voltage around [tex]500\Omega[/tex] resistance is

[tex]V=\dfrac{1}{40}\times 400\\\\V=10\ V[/tex]

(B) when voltmeter is connected around [tex]2000\Omega[/tex]  resistor

Net resistance around it

[tex]\Rightarrow \dfrac{1}{R}=\dfrac{1}{2000}+\dfrac{1}{2000}\\\\\Rightarrow R=1000\ \Omega[/tex]

Total resistance [tex]R_{net}=1500\ \Omega[/tex]

Current in circuit

[tex]I=\dfrac{60}{1500}=\dfrac{1}{25}\ A[/tex]

Voltage around [tex]2000\Omega[/tex] resistor

[tex]V=\dfrac{1}{25}\times 1000\\\\V=40\ V[/tex]

D. A negative externality.

Explanation:

Particulate pollution is a form of pollution that is responsible for the degradation of the environment.

Particulate matter is also referred to as particle pollution or atmospheric aerosol particles and it can be defined as a complex microscopic mixture of liquid droplets and solid particles that are suspended in air.

An externality is typically an unwarranted cost or benefit by a manufacturer or producer of goods and services that affects a third party.

In Economics, an externality could either be positive or negative depending on its effect on a third party.

A negative externality arises when the production or consumption of a finished product or service has negative impact (cost) on a third party.

In conclusion, air pollution is an example of a negative externality because it causes harm to a third party.

Explanation:

When conducting an experiment, researchers need to be aware of the ethics, or rules of conduct recognized in respect to the rightness or wrongness of certain actions on subjects.

The moral standards that should guide how researchers do their job are known as research ethics. These values guide the creation of research laws that have been approved by organisations like university governing bodies, local communities, or governments. All researchers are expected to abide by any rules that may be relevant to their work.

A collection of rules that guide your study designs and procedures are known as ethical concerns in research. Voluntary engagement, informed permission, anonymity, secrecy, the possibility of damage, and outcomes communication are some of these principles. Therefore, option (B) is correct.

Answer:

when volume and the number of particles are constant

Explanation:

Gay Lussac law states that when the volume of an ideal gas is kept constant, the pressure of the gas is directly proportional to the absolute temperature of the gas.

Mathematically, Gay Lussac's law is given by;

[tex] PT = K[/tex]

[tex] \frac{P1}{T1} = \frac{P_{2}}{T_{2}}[/tex]

The ideal gas law is the equation PV = nRT

Where;

P is the pressure.

V is the volume.

n is the number of moles of substance.

R is the ideal gas constant.

T is the temperature.

Generally, raising the temperature of an ideal gas would increase its pressure when volume and the number of particles are constant.

This ultimately implies that, when volume and the number of particles are held constant, there would be a linear relationship between the temperature and pressure of a gas i.e temperature would be directly proportional to the pressure of the gas. Thus, an increase in the temperature of the gas would cause an increase in the pressure of the gas at constant volume and number of particles.

Answer:

a) ball    K <K₀, b) the speed of the ball after the collision, c)  can K> 0

d) can moves in the same direction as the ball

Explanation:

a) the kinetic energy is given by

        K = ½ M v²

in this case before the collision the kinetic energy of the ball is

         K₀ = ½ M v₀²

After the collision the aluminum can has a certain speed, therefore the kinetic energy of the ball must decrease, the velocity of the ball after the collision is

          v <v₀

therefore the kinetic energy is

        K = ½ m v²

in consecuense

        K <K₀

b) an evidence of this fact is to measure the speed of the ball before the collision and the speed of the ball after the collision,

c) In the case of the aluminum can, the initial kinetic energy is ero, because it is stopped

          K₀ = 0

after the collision a part of the cal momentum of the ball is transferred to the can, therefore its velocity is different from zero

          K = ½ m v_can²

        K> 0

d) the clearest evidence of this fact is that the can moves in the same direction as the ball
