Answer:

C

Explanation:

The weight of an object is 1/6 of the earth's weight in the moon

For example if your weight is 54 kg on earth,

Weight on moon=1/6 of 54=1/6 x 54 = 9kg

Answer:

C. The weight of an object is the same on the Earth and the moon

Explanation:

The mass of an object is ⅙ of earth's weight on moon. So, option (C) is the false statement.

Answer:

He is incorrect. Dissolving salt in water and evaporation of the water are both physical changes. The reappearance of salt is evidence that the change was reversible by a physical change, so it could not be a chemical change.

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:

c. 0.02 C and 4 J

Explanation:

Applying,

Q = CV................ Equation 1

Where Q = Charge, C = Capacitance of the capacitor, V = Voltage.

From the question,

Given: C = 50 μF = 50×10⁻⁶ F, V = 400 V

Substitute these values into equation 1

Q = (50×10⁻⁶)(400)

Q = 0.02 C.

Also Applying

E = CV²/2............. Equation 2

Where E = Energy stored.

Therefore,

E = (50×10⁻⁶ )(400²)/2

E = 4 J

Hence the right option is c. 0.02 C and 4 J

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:

Explanation:

A simple machine that may be used the most often is called the wheel and axle. The wheel and axle has two basic parts: wheel and axle. They can be found everywhere. It has two circular objects which includes a larger disc and a small cylinder both joined at the center.The large disc is the wheel, and the small cylinder or rod is the axle. There may be two wheels attached to the axle.

There are two basic ways a wheel and axle can work together to help move things.

1. The Force is applied to the Wheel

For example, a screwdriver is an example of a wheel and axle. The handle is the wheel where the force is applied. It turns or spins and increases the force of the shaft or axle, which helps turn the screw.

Another example of force being applied to the wheel is when a doorknob is turned. The wheel (doorknob) is turned and the locking mechanism connected to the shaft turns and the door can then be opened.

2. The Force is applied to the Axle

A Ferris wheel is an example of force being applied to the axle. When the axle turns it results in the giant wheel turning. The wheel is much larger than the axle and covers more distance and area. A ceiling fan works the same way.

Answer:

1.17

Explanation:

Given that,

The refractive index of rock salt with respect to water is 1.17.

We need to find the refractive index of water with respect to rock salt.

We know that,

Refractive index = (speed of light in air or vaccum)/( speed of light in that medium)

Refractive index of rock salt with respect to ice = (speed of light in ice)/(speed of light in rock salt)

The speed of light in ice = c/1.31

The speed of light in rock salt = c/1.54

Required refractive index,

[tex]\mu=\dfrac{1.54}{1.31}\\\\=1.17[/tex]

So, the refractive index of water with respect to rock salt is equal to 1.17.

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

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

As acceleration is the rate of change of velocity with time, if velocity is uniform, there will be no change in it and acceleration will be zero.

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:

220 N

Explanation:

When a shopping cart rolls into a parked car on the street, it hits the car with a force of 220 newtons.

We need to find the force the shopping cart experiences from the car.

We know that, Newton's third law of motion states that for every action there is an equal and opposite reaction.

Hence, the shopping cart experiences a force of 220 N from the car.

Answer:

But where are the graphs

Coulomb's Law describes the relationship between electromagnetic force and the distance between charges.

The relationship between electromagnetic force and the distance between charges is described by Coulomb's Law, which states that the force between two charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them. Mathematically, Coulomb's Law is expressed as:

F = k  (q₁x q₂) / r²

where F is the electromagnetic force, q1 and q2 are the charges, r is the distance between the charges, and k is the Coulomb constant.

This means that as the distance between two charges increases, the force between them decreases, and as the distance decreases, the force increases. The relationship between force and distance is inverse square, which means that the force decreases rapidly as the distance increases.

Answer:

The correct answer is - transform boundary; plates slide past one another in opposite directions causing the formation of faults and earthquakes.

Explanation:

If the continental or oceanic plates slide past one another either in the same direction or in opposition direction forms the transform fault boundary. Due to this tectonic plate formation, no new crust is formed or subducted, but earthquake activities forms.

Convergent boundaries forms by pushing the edge of one plate underneath the other while coming together whereas plates move away from one another causing rift valleys called divergent boundary.
