The ideal gas equation can be changed to demonstrate that the pressure of a sample of gas is directly proportional to the amount of gas present, volume, and temperature being held constant: P=n(RTV)=n×const.

The pressure inside the object increases when medium is added to the newly created area. Because energy is being added during compression, the temperature of the medium may significantly rise or fall.

Therefore, compressing a medium is necessary to raise pressure. Compression reduces the volume of the medium that makes up a thing.

The process of converting one form of energy into another is referred to as energy conversion.

The process of converting energy from one form to another is referred to as energy transformation.  Energy is a quantity in physics that gives the capacity to perform labour or move (e.g., lifting an object) or provides heat. Energy, in addition to being converted, is transferable to a different location or object, but it cannot be created or destroyed, according to the law of conservation of energy.

Many sources of energy can be employed in natural processes or to give a service to society, such as heating, refrigeration, lighting, or mechanical work to power machines. For example, to heat a house, the furnace burns fuel, converting its chemical potential energy into thermal energy, which is then delivered to the house.

The buoyant force on a Styrofoam sphere that is 10% submerged in water is smaller that the buoyant force on a metal sphere that is 100% submerged in water, if the two volumes of the sphere are equal. Because water is incompressible, its density, stickiness, and other properties stay pretty much the same as you go deeper… and so the buoyant force stays the same as well.

A fluid's buoyancy, also known as upthrust, opposes the weight of an item that is partially or completely submerged by exerting an upward push. The weight of the fluid on top causes pressure in a fluid column to rise with depth. As a result, the pressure at the bottom of a fluid column is higher than at the top. Similar to this, an object submerged in a fluid experiences greater pressure at its bottom than it does at its top. A net upward force is exerted on the item as a result of the pressure differential. The size of the force equals the weight of the fluid that would otherwise fill the submerged volume of the item, direction, and its magnitude is proportional to the pressure difference.

Answer:

a.  Frequency is 5.45 x 10^14 hz

b.   The period = 1.8 x 10^-15 sec  {or 1.8 femptoseconds]

Explanation:

The velocity of an electromagnetic wave is given by the product of the wave's frequency(f) times its wavelength(λ).  

V = λ f     where,

V is the wave speed,

f is the wave frequency,

λ is the wavelength.

To find frequency, rearrange to:

f = V/ λ

Light travels at 3.00x10^8 m/sec.

λ is 5.50 x 10^-7 m

f = (3.00x10^8 m/sec)/(5.50 x 10^-7 m)  meters cancels, secs is on the bottom]

f = (3.00/5.50)*(10^15)  [The base 10 exponent on the bottom ius subtracted from the one on top:  98-(-7)) = 15)  

f = 0.545 x 10^15 1/s or hz

f = 5.45 x 10^14 hz

b.  The period of a wave is the inverse of it's frequesncy.  It is the time it takes for 1 wave to pass.  Invert the frequency:

 Period = 1/f

  Period =  1/(0.545 x 10^15 1/s)

Explanation:

A

Answer:

q = 0.036 C

Explanation:

Given that,

Current passes through a defibrillator, I = 18 A

Time, t = 2 ms

We need to find the charge moved during this time. We know that,

Electric current = charge/time

\(q=It\)

Put all the values,

\(q=18\times 0.002\\\\q=0.036\ C\)

So, 0.036 C of charge moves during this time.

To calculate the average deceleration of the bus, we can use the following formula:

Here, the initial velocity (v1) is 60 km/h, the final velocity (v2) is 40 km/h, and the time taken (t) is 8 seconds. To make the units consistent, we'll convert the velocities from km/h to m/s.

Now, we can plug the values into the formula:

Now, we'll find a common denominator for the fractions and simplify:

So, the average deceleration of the bus is approximately -150/216 m/s².

To lower the potential difference between the plates of the capacitor by 50.0 V, approximately 3.085 * 10^(-4) C (or 0.3085 mC) of charge needs to be removed.

To calculate the amount of charge that needs to be removed from a capacitor to lower the potential difference between its plates, we can use the formula: Q = C * ΔV

where Q is the charge, C is the capacitance, and ΔV is the change in potential difference.

Substituting these values into the formula, we have:

Q = (6.17 μF) * (50.0 V)

Before calculating the result, let's convert the capacitance from microfarads to farads:

1 μF = 10^(-6) F

So, the capacitance becomes:

C = 6.17 μF = 6.17 * 10^(-6) F

Substituting this value back into the formula, we get:

Q = (6.17 * 10^(-6) F) * (50.0 V)

Calculating the result:

Q = 3.085 * 10^(-4) C

Therefore, to lower the potential difference between the plates of the capacitor by 50.0 V, approximately 3.085 * 10^(-4) C (or 0.3085 mC) of charge needs to be removed.

Answer: 13 m/s

Explanation: The two vectors form a 5-12-13 right triangle. the magnitude of their resultant is the hypotenuse, which is 13 m/s.

The magnitude of the boat's resultant velocity (V) is 13 meters per second.

The velocity (v₁) of the boat heading in the eastward direction is in +ve (x-direction).

The velocity (v₂) of the current flowing in the south direction is in -ve (y-direction).

The magnitude of the boat's resultant velocity (V) can be determined by using the Pythagoras' rule:

∴

V² = V₁² + V₂²

V² = (12 m/s)² + (-5.0 m/s)²

\(\mathbf{V = \sqrt{(12 m/s)^2 + (-5.0 m/s)^2}}\)

\(\mathbf{V = \sqrt{(144 m/s) + (25m/s)}}\)

\(\mathbf{V = \sqrt{(169 \ m/s) )}}\)

V = 13 m/s

According to given statement, the average force exerted on the ball by the bat is -11,361.56 N in the negative direction.

To calculate the average force exerted on the ball by the bat, we can use the impulse-momentum principle. According to this principle, the change in momentum of an object is equal to the impulse applied to it.

First, let's calculate the initial momentum of the ball before it is hit by the bat. The momentum of an object can be calculated by multiplying its mass by its velocity. The mass of the baseball is given as 205.00 g, which is equivalent to 0.205 kg. The initial velocity of the ball is 35.70 m/s, and we'll consider it positive since it is approaching the bat in the positive direction.

Initial momentum = mass × initial velocity
Initial momentum = 0.205 kg × 35.70 m/s
Initial momentum = 7.3135 kg·m/s

Next, let's calculate the final momentum of the ball after it is hit by the bat. The final velocity of the ball is 53.00 m/s, and we'll consider it negative since it is moving in the opposite direction.

Final momentum = mass × final velocity
Final momentum = 0.205 kg × (-53.00 m/s)
Final momentum = -10.865 kg·m/s

Now, let's calculate the change in momentum by subtracting the initial momentum from the final momentum.

Change in momentum = Final momentum - Initial momentum
Change in momentum = -10.865 kg·m/s - 7.3135 kg·m/s
Change in momentum = -18.1785 kg·m/s

According to the impulse-momentum principle, the change in momentum is equal to the impulse applied to the ball, which is also equal to the average force multiplied by the time of contact.

Change in momentum = average force × time of contact

Now we can rearrange this equation to solve for the average force.

Average force = change in momentum / time of contact
Average force = (-18.1785 kg·m/s) / (1.60 × 10⁻³ s)
Average force = -11,361.56 N

Since we have chosen the direction of the incoming ball as the positive direction, the average force exerted on the ball by the bat is -11,361.56 N in the negative direction.

In conclusion, the average force exerted on the ball by the bat is -11,361.56 N in the negative direction.

When a rock on the edge of a cliff falls off, the rock converts its potential energy into kinetic energy. In other words, it begins to move, accelerating towards the ground.

When it falls, the gravitational potential energy that the rock had on the cliff is converted into kinetic energy because of gravity. The rock moves faster and faster as it falls. Hence, at the point where the rock falls from the cliff, it has a maximum amount of potential energy, but no kinetic energy yet.As the rock falls from the cliff, the speed and velocity of the rock changes. Due to the acceleration of gravity acting upon the rock, the velocity of the rock increases steadily as it falls. Hence, the potential energy decreases while the kinetic energy increases as it nears the ground. Therefore, the rock’s kinetic energy increases as it approaches the ground.

When it strikes the ground, all its kinetic energy is absorbed and the rock comes to a complete stop, converting all of the kinetic energy into other forms of energy such as sound energy, heat energy, and deformation energy (if the ground is not hard).The transformation of the rock's potential energy into kinetic energy and the subsequent conversion of kinetic energy to sound energy, heat energy, and deformation energy upon impact is known as the principle of the conservation of energy.

To find the current in the resistor, we can use Ohm's Law and the concept of equivalent resistance. Thus, option A is correct.

First, let's calculate the equivalent resistance of the three cells connected in parallel. When resistors are connected in parallel, the reciprocal of the equivalent resistance is equal to the sum of the reciprocals of the individual resistances:

1/Req = 1/R1 + 1/R2 + 1/R3

Given that R1 = R2 = R3 = 22 Ω (internal resistance of each cell), we can substitute the values:

1/Req = 1/22 + 1/22 + 1/22

1/Req = 3/22

Taking the reciprocal of both sides, we find:

Req = 22/3 Ω

Now we can use Ohm's Law to calculate the current (I) in the resistor. Ohm's Law states that the current flowing through a resistor is equal to the voltage across it divided by its resistance:

I = V/R

Given that V = 1.1 V (emf of each cell) and R = 32 Ω (resistance), we can substitute the values:

I = 1.1/32

Calculating this value, we find:

I ≈ 0.034375 A

Therefore, the current in the resistor is approximately 0.034375 A.
