What is the formula to determine the mass of the Earth?​

Answer:

The total volume of the air is 1000 cubic centimeters.

Explanation:

Since the bicycle pump and the bicycle tyre have the same pressure, then the total volume of the air is the sum of the volume of each element, then we translate this into the following artihmetical expression:

[tex]V = 200\,cm^{3}+800\,cm^{3}[/tex]

[tex]V = 1000\,cm^{3}[/tex]

The total volume of the air is 1000 cubic centimeters.

Explanation:

There are countless household appliances in every single house. One appliance with a low power rating would be a ceiling fan. On average ceiling fans consume roughly 60w and are found in the majority of houses. On the other side of the spectrum, we have a high power-rating appliance such as a microwave. Microwaves use anywhere between 1000w to 1800w of power in order to function correctly. This is very large power consumption and one of the highest power ratings found for appliances in a household.

Answer:

d = 0.343 m

Explanation:

Given that,

The speed of a longitudinal wave, v = 343 m/s

Your ear is capable of differentiating sounds that arrive at the ear just 1.00 milliseconds apart.

We need to find the minimum distance between two speakers that produce sounds that arrive at noticeably different times.

Let the distance be d. So,

[tex]d=v\times t\\\\=343\times 10^{-3}\\\\=0.343\ m[/tex]

So, the required distance is equal to 0.343 m.

From the wording of the question, I'm suspecting that you have ...

... an inductor to play with and measure, either in your hand or on the screen.

I have none of these advantages.

In fact, nobody reading this on Brainly has.

Answer:

The wave moves with a velocity of 37.5 m/s

Explanation:

We know that the speed of a wave is given by:

V = f*λ

Where f is the frequency (the inverse of the period)

Then:

f = 1/T

And we know that T = 2 s/cycle

f = 1/(2 s/cycle) = (1/2) cycle/s

And λ is the wavelength, we know that:

λ = 75m/cycle.

Then the speed of the wave is:

v = ( (1/2) cycle/s)*(75m/cycle) = (75/2) m/s = 37.5 m/s

Answer:

At that time, she was in the southern hemisphere

Explanation:

She is witnessing the southeastern trade breeze because the cloud is passing from east to west and she is also witnessing a storm from the southeast.

Because of the Coriolis effect, which deviates the atmosphere in the left-hand side of the southern hemisphere and generates a southeastern wind, this wind did not blow directly from south to east.

Answer: In physics, mass is not the same as weight, even though mass is often determined by measuring the object's weight using a spring scale, rather than balance scale comparing it directly with known masses.

Explanation:

In physics, mass is not the same as weight, even though mass is often determined by measuring the object's weight using a spring scale, rather than balance scale comparing it directly with known masses.

The force between the two charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them. Hence, if distance between charges is halved (charges remaining kept constant), the force between the two charges is quadrupled.

Answer:

Coming from my perspective sence I see the lines are super long during lunch I would have to say McDonald’s

Answer:

Superconducting materials can transport electrons with no resistance, and hence release no heat, sound, or other energy forms. Superconductivity occurs at a specific material's critical temperature (Tc). As temperature decreases, a superconducting material's resistance gradually decreases until it reaches critical temperature. At this point resistance drops off, often to zero, as shown in the graph at right.

First Resistance R1 = 1 ohm

Second Resistance R2 = 4 ohm

Resistor connected in series

Find:

Current in circuit

Computation;

Resistor connected in series

So,

Total resistance R = First Resistance R1 + Second Resistance R2

Total resistance R = 1 ohm + 4 ohm

Total resistance R = 5 ohm

Current in circuit = V / R

Current in circuit = 10 / 5

Current in circuit = 2 amp

Solution :

Mass of the particle = M

Speed of travel = v

Energy of one photon after the decay which moves in the positive x direction = 233 MeV

Energy of second photon after the decay which moves in the negative x direction = 21 MeV

Therefore, the total energy after the decay is = 233 + 21

                                                                           = 254 MeV

So by the law of conservation of energy, we have :

Total energy before the decay = total energy after decay

So, the total relativistic energy of the particle before its decay = 254 MeV

Answer:

v = -227.785 m/s

Explanation:

The electric field exerts the following force on the electric particle:

F = qE

[tex]F = 6.65 \times 10^{-6} \times 1230[/tex]

[tex]F = 0.0081795 \ N[/tex]

The magnetic field exerts the following force on the particle::

F = qvB

[tex]F = 6.65\times 10^{-6} \times v \times 1.32[/tex]

[tex]F = 8.778 \times 10^{-6} \times v[/tex]

Total force acting is:

F = qvB + qE

[tex]6.18 \times 10^{-3} = 0.0081795 + 8.778 \times 10^{-6} \times v[/tex]

[tex]v = \dfrac{6.18 \times 10^{-3} -0.0081795 }{8.778 \times 10^{-6}}[/tex]

v = -227.785 m/s

Answer:

The gradient here represents Angela's Velocity.

Explanation:

A distance-time graph has distance on its y-axis and time on its x-axis. Therefore, the gradient of the distance-time graph is given by the following formula:

[tex]Gradient = \frac{Change\ on\ y-axis}{Change\ on\ x-axis} \\\\Gradient = \frac{Distance\ Covered\ by\ Angela}{Time\ taken\ to\ cover\ the\ distance}\\\\Gradient = Angela's\ Velocity[/tex]

Since the rate of change of distance is called the velocity.

Therefore, the gradient here represents Angela's Velocity.

Explanation:

Answer:

Mass is the amount of matter in an object and the mass of an object does not change location.

when we placed in the container of real depth assuming = d

if the container filled with liquid A then its apparent depth d' = 7cm

so the refractive index nA = real depth / apparent depth

                                       = d/7cm = 0.1428d

if the container filled with liquid B then its apparent depth d' = 6cm

so the refractive index nB = real depth / apparent depth

                                       = d/6cm = 0.166d

if the container filled with liquid C then its apparent depth d' = 5cm

so the refractive index nC = real depth / apparent depth

                                       = d/5cm = 0.2d

Since the refractive index is inversely proportional to the apparent depth

then the refractive indices are nC > nB > nA

Answer:

vf = 9.48 m/s

Explanation:

From the law of conservation of energy we can write:

[tex]Kinetic\ Energy\ Lost = Work\ Against\ Friction\\\frac{1}{2}m(v_i^2 - v_f^2) = fd\\\frac{1}{2}m(v_i^2 - v_f^2) = (\mu W)d\\\frac{1}{2}m(v_i^2 - v_f^2) = (\mu mg)d\\\frac{1}{2}(v_i^2 - v_f^2) = \mu gd\\v_f^2 = v_i^2 - 2\mu gd[/tex]

where,

vf = final speed = ?

vi = initial speed = 10.1 m/s

μ = coefficient of friction = 0.3

g = acceleration due to gravity = 9.81 m/s²

d = distance covered = 2.07 m

Therefore,

[tex]v_f^2 = (10.1\ m/s)^2 - 2(0.3)(9.81\ m/s^2)(2.07\ m)\\v_f^2 = 102.01\ m^2/s^2 - 12.18\ m^2/s^2\\v_f = \sqrt{89.83\ m^2/s^2}\\[/tex]

Answer:

f lamda = c

Explanation:

525 m/s is the speed

A wave has a frequency of 35 Hz and a wavelength of 15 meters, Then the speed of the wave is 525 meters per second(m/s).

The speed of a wave is the distance that a wave travels per unit of time. It is a measure of how quickly the disturbance created by the wave is propagated through a medium. The speed of a wave can be calculated using the formula:

Speed = Frequency x Wavelength

Where the frequency  = is the number of wave cycles per second

wavelength = is the distance between two consecutive points on the wave that is in phase (i.e., at the same point in their oscillation).

The speed of a wave depends on the properties of the medium through which it is traveling, such as its density, elasticity, and temperature.

Here in the question,

Speed = Frequency x Wavelength

Speed = 35 Hz x 15 meters

Speed = 525 meters per second(m/s).

Therefore, the speed of the wave is 525 meters per second.

Explanation:

The principle of cross-cutting relationships states that a fault or intrusion is younger than the rocks that it cuts through. The fault labeled "E" cuts through all three sedimentary rock layers (A, B,and C) and also cuts through the intrusion (D). So the fault must be the youngest formation that is seen and known of.

The age of the fault A is in between rock B and intrusion D. Hence A is the youngest rock and C be the oldest rock here.

A fault is a crack or region of cracks that separates two rock blocks. The blocks might move in relation to one another due to flaws. This movement may happen suddenly, like an earthquake, or it may happen gradually, like creep.

From a few millimeters to thousands of kilometers, faults can vary in length. Over geologic time, most faults cause recurrent displacements. The rock on one side of the fault abruptly shifts in relation to the other during an earthquake. The fault surface may be vertical, horizontal, or at any other arbitrary angle.

The principal of superposition states that, the oldest layer will be the bottom of the young rocks. Here, rock is A is above B and C. Hence, rock A is youngest than layer B and C.

Answer:

Resistance, R = 60 Ohms

Explanation:

Given the following data;

For the first heater;

Voltage, V = 120 V

Resistance, R = 15 Ohms

For the second heater;

Voltage, V = 240 V

To find the resistance in the second heater;

First of all, we would determine the power rating of the heaters using the formula below;

Power = voltage²/resistance

Power = 120²/15

Power = 14400/15

Power = 960 Watts

Next, we find the resistance in the second heater;

Power = V²/R

960 = 240²/R

Cross-multiplying, we have;

960R = 57600

R = 57600/960
