There are two basic theoretical explanations of how we sense the pitch of a sound: frequency theory and place theory. Which theory best explains our sensation of sounds that have a pitch in the midrange frequency
Answers
Frequency theory best explains our sensation of sounds that have a pitch in the midrange frequency.
According to the frequency theory, the perception of pitch is directly related to the frequency of the sound wave. In this theory, it is believed that the nerve impulses generated by the sensory receptors in the ear match the frequency of the sound wave, resulting in the perception of pitch.
In the midrange frequency, the sensory receptors in the ear are capable of accurately detecting and matching the frequency of the sound wave, leading to a reliable perception of pitch.
Place theory, on the other hand, suggests that pitch perception is based on the specific location along the cochlea where the sound wave stimulates the sensory receptors. However, this theory is more applicable to high-frequency sounds.

Answers
Answer:
Mass and gravity
Explanation:
\({ \rm{weight = mass \times gravity}}\)
Weight is the force exerted on an object due to gravity. The correct answer is mass and gravity. The correct option is an option (3).
Weight requires both mass and gravity.
The formula for calculating weight is given by:
Weight = mass × gravitational acceleration
W = m × g
The gravitational acceleration is known by the strength of the gravitational field, which is typically constant at any given point.
The mass of an object and the strength of its gravitational field is its weight. It is the gravitational force that pulls an object toward the center of the Earth.

a key difference between the protoplanets that formed in the outer solar system and those that formed in the inner solar system was that
Answers
A key difference between the protoplanets that formed in the outer solar system and those that formed in the inner solar system was that they were composed of different types of material.
What is a protoplanet?Protoplanets are early-stage planets that are still forming, as well as the residual planetesimals that made them. They are believed to have formed in the early solar system's planetesimal disk, which was composed of gas and dust.
In the inner solar system, rocky fragments and dust grains with higher melting points accumulated to produce rocky protoplanets, whereas in the outer solar system, where temperatures were colder, volatile materials like water and methane condensed and formed the cores of the protoplanets instead of rocky material.
These protoplanets then drew more material from the surrounding planetesimal disk and eventually formed the planets we see today.

an electrical con dows a current 9 SO.A When Cornee it to a 250 Jm: supply. calculare by the iron fat is used The energy consumed For ten minutes
Answers
The energy consumed by the iron for ten minutes is 1.5 kWh.
To calculate the energy consumed by the iron for ten minutes, we can use the formula:
Energy (in kilowatt-hours) = Power (in kilowatts) x Time (in hours)
First, let's convert the current from amperes to kilowatts. We know that 1 ampere is equal to 1 watt, so 9.50 amperes is equal to 9.50 watts.
Next, we need to convert the time from minutes to hours. Since there are 60 minutes in an hour, ten minutes is equal to 10/60 = 1/6 hour.
Now we have all the information we need to calculate the energy consumed:
Power = 9.50 watts
Time = 1/6 hour
Plugging these values into the formula:
Energy = 9.50 watts x 1/6 hour
Simplifying the expression:
Energy = 1.58 watt-hours
Since 1 kilowatt-hour (kWh) is equal to 1000 watt-hours, we can convert the energy to kilowatt-hours:
Energy = 1.58 watt-hours / 1000
Energy = 0.00158 kilowatt-hours
Rounding the value to two decimal places, the energy consumed by the iron for ten minutes is approximately 0.00 kWh or 1.5 kWh.

The breaking of chemical bonds

Answers
The breaking of chemical bonds can either absorb or release energy, depending on the type of chemical reaction. Some chemical reactions release energy when bonds are broken, while others absorb energy. So the correct answer is option: 4.
In exothermic reactions, the energy released by the breaking of chemical bonds is greater than the energy required to break the bonds. Therefore, the excess energy is released in the form of heat, light, or sound.
In endothermic reactions, the energy required to break the bonds is greater than the energy released. Therefore, energy must be absorbed from the surroundings in order to break the bonds. Correct option is 4.

A.
Specific energy
B.
Specific mass
C.
Specific gravity
D.
Specific heat
Answers
Answer:
The answer is specific heat.
Explanation:
The amount of energy for 1 gram of a substance to be raised one degree is called specific heat because it involves energy and temperature going up.
Heat is a form of energy, so it is the most appropriate name.
I hope this helps! :)
The amount of heat required to increase the temperature of 1 gram of a substance by 1 degree Celsius (°C) is known as specific heat. Since water has a higher specific heat than other substances, it requires more energy to raise its temperature. Thus, option D is correct.
What are the characteristics of Specific heat?One gram of a substance's temperature can be raised by one degree Celsius by applying a certain amount of heat, or specific heat.
Calories or joules per gram per Celsius degree are typically used as the units of specific heat. One calorie (or 4.186 joules) per gram per degree Celsius, for instance, is the specific heat of water.
Specific heat is the quantity of energy required to raise a substance's temperature by one degree in order to raise a gram of it.

.The tension in the cable attaching the platform to the building on the right is 750 N (30 degrees):
a) What is the tension in the cable attaching the platform to the building on the left (45 degrees)?
b) What is the inertia of the platform?
Answers
a) The tension in the cable attaching the platform to the building on the left is approximately 516 N.
b) the inertia of the platform is approximately 188.9 kg·m^2.
To answer these questions, we need to use trigonometry and the principles of statics.
a) To find the tension in the cable attaching the platform to the building on the left, we can use the fact that the platform is in static equilibrium, which means that the net force acting on it is zero. We can break the tension force into its horizontal and vertical components:
Horizontal component of tension = T * cos(45 degrees)
Vertical component of tension = T * sin(45 degrees)
where T is the tension in the cable attaching the platform to the building on the left.
The vertical components of the tension forces from both cables balance each other out, since the platform is not moving up or down. Therefore:
T * sin(45 degrees) = 750 N * sin(30 degrees)
Solving for T, we get:
T = 750 N * sin(30 degrees) / sin(45 degrees) ≈ 516 N
Therefore, the tension in the cable attaching the platform to the building on the left is approximately 516 N.
b) To find the inertia of the platform, we need to know its mass and its distance from the axis of rotation. Assuming that the platform is a uniform disc with radius r, its moment of inertia is given by:
I = (1/2) * m * r^2
where m is the mass of the platform.
To find the mass of the platform, we can use the fact that the tension force from both cables balances the weight of the platform:
T * cos(45 degrees) + 750 N * cos(30 degrees) = m * g
where g is the acceleration due to gravity.
Solving for m, we get:
m = (T * cos(45 degrees) + 750 N * cos(30 degrees)) / g
Substituting the value of T from part a) and using g = 9.81 m/s^2, we get:
m ≈ 60.5 kg
Substituting the values of m and r into the equation for moment of inertia, we get:
I ≈ (1/2) * 60.5 kg * (2.5 m)^2 ≈ 188.9 kg·m^2
Therefore, the inertia of the platform is approximately 188.9 kg·m^2.

Answers
The Energizer 522 V battery can operate such a relay for approximately 0.69 h.
The power consumption of the relay's coil is 6.75 W. The Energizer 522 V battery has a capacity of 522 mA. To calculate how long the battery can operate the relay, we need to know the current draw of the relay in mA.
Since the current draw of the relay is 750 mA, we can use the following formula:
Time (h) = Battery Capacity (mA) / Current Draw (mA)
Time (h) = 522 mA / 750 mA
Time (h) = 0.69 h
Therefore, the Energizer 522 V battery can operate such a relay for approximately 0.69 h.

Water is heated by = 8 × 10² W = 800 W
Time = 10 min = 10 × 60 = 600 s
Now, using the equation of specific heat,
Q = mcΔT
