Answer:

p = 65.52 kg m/s

Explanation:

p = m × v

p = 31.2 × 2.1

p = 65.52 kg m/s

Answer:

t = 12.25 s

Explanation:

First we calculate the time taken by the car during accelerating motion, we use 1st equation of motion:

Vf = Vi + at₁

where,

Vf = Final Velocity = 21 m/s

Vi = Initial Velocity = 0 m/s

a = acceleration = 3 m/s²

t₁ = time taken during acceleration = ?

Therefore,

21 m/s = 0 m/s + (3 m/s²)t₁

t₁ = (21 m/s)/(3 m/s²)

t₁ = 7 s

Now, we use the same equation to find out the time taken during deceleration motion, with following data:

Vf = Final Velocity = 0 m/s

Vi = Initial Velocity = 21 m/s

a = deceleration = -4 m/s²

t₂ = time taken during deceleration = ?

Therefore,

0 m/s = 21 m/s + (-4 m/s²)t₂

t₂ = (-21 m/s)/(-4 m/s²)

t₂ = 5.25 s

Therefore, the total time taken by the car to travel from first stop sign to second stop sign is:

t = t₁ + t₂

t = 7 s + 5.25 s

t = 12.25 s

Answer:

To determine the sound intensity in decibels (dB) at a certain distance from the speakers, we can use the formula for sound intensity level:

Where L is the sound intensity level in dB, I is the sound intensity, and I0 is the reference intensity (usually taken as the threshold of hearing, which is 1.0 x 10^-12 W/m^2).

First, we need to calculate the sound intensity at the specified distance from each speaker using the formula:

Where I is the sound intensity, P is the power of the speaker, and r is the distance from the speaker.

For the first speaker with a power of 100 W and a distance of 2.0 m:

For the second speaker with a power of 200 W and a distance of 2.0 m:

Next, we can calculate the sound intensity level (L) at the specified distance using the formula mentioned earlier:

For the first speaker:

For the second speaker:

Since the two speakers are playing simultaneously, the total sound intensity at the specified distance is the sum of the intensities from each speaker:

The total sound intensity level (Ltotal) can be calculated using the same formula:

Therefore, at a distance of 2.0 m from each speaker, you would hear a sound intensity of approximately 140 dB.

The decibel is a unit for measuring sound intensity. One decibel is equivalent to one tenth of a bel. The "B" in dB is capitalized because it is part of the name of its inventor, Bell. The decibel is also a logarithmic unit for describing a ratio. The unit of measurement for sound noise is the decibel (dB). The higher the sound noise, the higher the decibel size. Sound that has a high decibel has the possibility of causing damage to the ear.

Answer:

Acceleration = -3m/s²

Explanation:

Given the following data;

Initial velocity = 19m/s

Final velocity = 3m/s

Time = 2secs

To find the acceleration;

In physics, acceleration can be defined as the rate of change of the velocity of an object with respect to time.

This simply means that, acceleration is given by the subtraction of initial velocity from the final velocity all over time. Mathematically, acceleration is given by the equation;

\(Acceleration (a) = \frac{final \; velocity - initial \; velocity}{time}\)

Substituting into the equation, we have;

\(a = \frac{3 - 9}{2}\)

\(a = \frac{-6}{2}\)

Acceleration = -3m/s²

The value for her acceleration is negative because she is decelerating i.e her final velocity is lower than her initial velocity.

One of the most fundamental and significant principles controlling electrical and electronic circuits is called Ohm's Law. For a linear device, it relates current, voltage, and resistance.

According to Ohm's Law, the current flowing through a circuit is inversely proportional to the resistance in the circuit and directly proportional to the applied potential difference.

Ohm's law can be written mathematically as follows:

V = IR

Where:

   V = voltage expressed in Volts

   I = current expressed in Amps

   R = resistance expressed in Ohms

If any two quantities are known, the third can be computed by manipulating the formula.

   I= V/R

   R= V/I

The average acceleration vector of the ball is approximately 9.8 m/s² downward.

When the ball is thrown upward, it experiences a constant acceleration due to gravity pulling it downward. This acceleration is equal to 9.8 m/s², which is the acceleration due to gravity near the surface of the Earth. Since the ball reaches the same speed in the downward direction when it returns to the hand, we can conclude that its average acceleration vector is also 9.8 m/s² downward.

When the ball is thrown upward, it moves against the force of gravity. As it moves upward, the gravitational force slows it down until it reaches its highest point. At this point, the ball momentarily stops before reversing direction and falling back downward.

The force of gravity then acts in the same direction as the ball's motion, causing it to accelerate downward. The acceleration due to gravity remains constant throughout the ball's motion, regardless of its direction.

C. the blue colour of the Earth's sky

Explanation:

The Pleiades is a cluster of sister stars that are among the closest star cluster to earth.

The reflection nebula of the Pleiades is due to the scattering of the blue light from the hot blue luminous stars that dominate the star cluster. Th blue light is scattered from dust molecules, thought to be predominantly carbon compound like diamond dusts, and other compounds like iron.

The blue colour of the Earth's sky is the closest terrestrial phenomenon to the reflection nebula. On a clear cloudless day, molecules in the air scatter the blue component of light more than the other component colours of white light, giving the sky its characteristic blue coluor.

The common characteristics of the luminous nebula and the Earth's blue sky is that they both have their light scattered by the presence of small particles.

If a 0.3% decrease in the price of a good causes its quantity supplied to decrease by 1%, then the supply is C. Inelastic.

In this scenario, the supply of the good is considered inelastic. The elasticity of supply measures the responsiveness of the quantity supplied to changes in price. When the price of a good decreases, and the quantity supplied decreases by a larger percentage, it indicates that the supply is relatively unresponsive to price changes.

To determine the elasticity of supply, we compare the percentage change in quantity supplied to the percentage change in price. In this case, a 0.3% decrease in price results in a 1% decrease in the quantity supplied. Since the percentage change in quantity supplied (1%) is greater than the percentage change in price (0.3%), the supply is considered inelastic.

Inelastic supply means that producers are less responsive to price changes, and a small change in price leads to a proportionally smaller change in quantity supplied. In such cases, producers may find it challenging to adjust their output levels quickly in response to price fluctuations.

Explanation:

When electrons are accelerated through a potential difference, they gain kinetic energy. In this case, the electrons are accelerated through a potential difference of 890 kV, resulting in a kinetic energy of \(8.90 × 10^5 eV.\)To understand this concept, let's break it down step-by-step:

1. Potential difference: This refers to the voltage applied across the acceleration region. In this case, it is 890 kV, where "kV" stands for kilovolts.

2. Kinetic energy: This is the energy associated with the motion of an object. In this case, the electrons gain a kinetic energy of\(8.90 × 10^5 eV\), where "eV" stands for electron volts.

3. Conversion: To convert the potential difference from kilovolts to electron volts, we multiply by the elementary charge of an electron, which is approximately\(1.6 × 10^-19 C\) (coulombs). So, \(890 kV * (1.6 × 10^-19 C/eV) = 1.424 × 10^-14 eV.\)

4. Conclusion: The electrons gain a kinetic energy of \(1.424 × 10^-14 eV\)when accelerated through a potential difference of 890 kV.

In summary, the potential difference of 890 kV accelerates electrons, resulting in a kinetic energy of\(8.90 × 10^5 eV.\)
