Explanation:
If no force is exerted on a moving object, it will continue to move at a constant velocity. This is described by Newton's first law of motion, which states that an object will remain at rest or continue to move at a constant velocity in a straight line unless acted upon by an external force. In other words, if no net force acts on an object, the object will maintain its velocity, neither speeding up nor slowing down.
no attempt no attempt 33% part (a) if the musical notes a and c are played together (frequencies of 220 and 264 hz)?
When musical notes A and C with frequencies of 220 Hz and 264 Hz are performed simultaneously, a phenomenon known as interference occurs.
What is frequency?The frequency of a repeated event is the number of occurrences per unit of time. It is separate from angular frequency and is sometimes referred to as temporal frequency. The unit of frequency is hertz, which equals one occurrence every second. The frequency difference between notes A and C is 44 Hz, which can result in a complex sound wave with a variety of harmonic overtones. Many factors will influence the exact form of the interference pattern, including the strength and phase of the original waves, the distance between the listener and the source of the sound, and the existence of any additional sound waves in the surroundings.
Here,
This happens because the sound waves created by each note interact with one another, either enhancing or canceling out at different places in space. The resultant wave pattern combines the two original waves to generate a new waveform with its own distinct frequency and amplitude.

Velocity is a vector quantity that refers to the rate of change of an object's position with respect to time. It measures the speed of an object in a specific direction. The unit of velocity is meters per second (m/s) or miles per hour (mph) depending on the measurement system being used. In physics, velocity is considered a fundamental concept that is used to describe the motion of objects in the physical world.
Velocity is calculated by dividing the change in position by the change in time. For example, if an object moves 10 meters in 2 seconds, its velocity would be 5 m/s in the direction of the movement. It is important to note that velocity is not the same as speed, which is only concerned with the magnitude of the velocity and not the direction.

how many hours will it take to fill a cubic vat of 18.9 ft edge length with a liquid that has a density of 1.31 g/ml and is spilling at a rate of 3.09 kg/s?
Therefore, it will take around 2.41 hours to fill an 18.9-foot-long cubic vat with a liquid whose density is 1.31 g/ml and which is pouring at a rate of 3.09 kg/s.
To calculate the time it takes to fill a cubic vat with a liquid, we need to find the volume of the vat and multiply it by the density of the liquid to find its mass.
Then, divide the mass of the liquid by the rate at which it's spilling to find the time required to fill the vat.
The volume of a cubic vat with an edge length of 18.9 ft can be calculated as follows:
V = l^3 = (18.9 ft)^3
= 12,092.973 ft^3
Next, we need to convert the volume to liters:
V = 12,092.973 ft^3 * 28.3168466 L/ft^3
= 342,190.4 L
Next, we can multiply the volume in liters by the density of the liquid in g/mL to find its mass:
m = V * d = 342,190.4 L * 1.31 g/mL
= 448,111.54 g
= 448.11 kg
Finally, we divide the mass of the liquid by the rate at which it's spilling to find the time required to fill the vat:
t = m / r = 448.11 kg / 3.09 kg/s
= 144.52 s
= 2.41 hours.
Therefore, it will take approximately 2.41 hours to fill the cubic vat.

The difference between the frequencies of two succeeding overtones can be used to determine the frequency of the fundamental (first overtone) of a vibrating string.
Let's use the letters f1 for the fundamental overtone's frequency and f2 and f3 for the overtones that follow.
F2 = 320 Hz, and F3 = 400 Hz, as we are aware.
The following gives the relationship between the fundamental's frequency and its overtones:
f2 = 2 * f1\sf3 = 3 * f1
Therefore, we may equalize the two equations:
320 Hz = 2 * f1
400 Hz = 3 * f1
by the matching overtone number in each equation:
320 Hz / 2 = f1
400 Hz / 3 = f1

if the pressure amplitude were increased by a factor of 10.0, what would the new sound intensity level be?
The new sound intensity level, L', will be 20 dB higher than the original sound intensity level, L. The sound intensity level, L, is a measure of the sound wave's power per unit area, relative to a reference value. It is expressed in decibels (dB).
The sound intensity level, L, is defined as 10 log (I/I0), where I is the intensity of the sound wave and I0 is the reference intensity. To find the new sound intensity level if the pressure amplitude is increased by a factor of 10.0, we first need to find the new intensity of the sound wave.
The sound intensity, I, is proportional to the square of the pressure amplitude, P:
I ∝ P²
So if the pressure amplitude is increased by a factor of 10.0, the intensity will be increased by a factor of 10.0² = 100.0. The new intensity, I', is given by:
I' = 100.0I
Using this new intensity, we can find the new sound intensity level:
L' = 10 log (I'/I0) = 10 log (100.0I/I0) = 10 log (100.0) + 10 log (I/I0) = 20 + L
So the new sound intensity level, L', will be 20 dB higher than the original sound intensity level, L.
In this calculation, we use the fact that log (ab) = log a + log b, where a and b are positive numbers.
So, if the pressure amplitude were increased by a factor of 10, the new sound intensity level would be 20 dB higher than the original sound intensity level. This relationship between pressure amplitude, intensity, and sound intensity level is important for understanding the physical properties of sound waves and for comparing the strength of different sounds.

An astronaut stands on the edge of a lunar crater and throws a half-eaten Twinkie™ horizontally with a velocity of 5.00 m/s. The floor of the crater is 100.0 m below the astronaut. What horizontal distance will the Twinkie™ travel before hitting the floor of the crater? (The acceleration of gravity on the moon is 1/6th that of the Earth).
Answer:
33.35 meters
Explanation:
The horizontal distance traveled by the Twinkie™ can be calculated using the following equation:
d = v0 * t
Where v0 is the initial horizontal velocity, and t is the time it takes for the Twinkie™ to reach the floor of the crater. To find t, we can use the equation for the vertical motion of the Twinkie™:
y = v0y * t - (1/2) * g * t^2
Where v0y is the initial vertical velocity, g is the acceleration due to gravity on the moon (1/6th that of the Earth), and y is the vertical distance from the astronaut to the floor of the crater (100 m). Since the Twinkie™ was thrown horizontally, the initial vertical velocity is 0, so the equation simplifies to:
100 = - (1/2) * (1/6 * 9.8) * t^2
Solving for t:
t = sqrt(100 * 2 / (1/6 * 9.8)) = sqrt(100 * 2 * 6 / 9.8) = sqrt(1200 / 9.8) = 6.67 seconds
Finally, we can use the horizontal velocity and the time to calculate the horizontal distance traveled by the Twinkie™:
d = v0 * t = 5.00 m/s * 6.67 s = 33.35 m
So the Twinkie™ will travel 33.35 meters horizontally before hitting the floor of the crater.

Supplies will be dropped from a rescue plane 220 metres below. if the aircraft is moving at 80 metres per second So the magnitude of the velocity of the supply when it lands is 65.076 m/s.
The velocity of an object under constant acceleration (in this case, due to gravity) can be found using the equation
v = v_0 + a * t
where v is the final velocity, v_0 is the initial velocity,
a is the acceleration (in this case, due to gravity,
which has a magnitude of 9.8 m/s^2),
and t is the time it takes for the object to fall.
To find t, we can use the equation:
d = v_0 * t + 0.5 * a * t^2
where d is the distance the object falls.
Solving for t:
t = √(2d/a)
= √(2 * 220 m / 9.8 m/s^2)
= 6.62 s
Now we can plug the value of t back into the equation for v:
v = v_0 + a * t

the magnitude of the force of gravity acting on an object is
The magnitude of force of gravity on an object, mg is called weight of the object on earth.
In physics, gravity (from Latin gravitas 'weight') is a fundamental interaction which reasons mutual enchantment between all matters with mass or strength. Gravity is, by a long way, the weakest of the 4 fundamental interactions, approximately 1038 instances weaker than the strong interaction, 1036 times weaker than the electromagnetic pressure and 1029 times weaker than the weak interaction.
As an end result, it has no significant have an impact on at the level of subatomic debris. but gravity is the most significant interaction among objects at the macroscopic scale, and it determines the movement of planets, stars, galaxies, or even mild.

what is the escape speed of an electron launched from the surface of a 1.4- cm -diameter glass sphere that has been charged to 10 nc ?
The escape speed of an electron launched from the surface of the sphere comes out to be approximately 1.6 x 10^6 m/s.
The escape speed of an electron launched from the surface of a charged sphere can be calculated using the following equation:
v_escape = sqrt(2 * k * q / m)
where k is Coulomb's constant,
q is the charge on the sphere,
and m is the mass of the electron.
For a glass sphere with a diameter of 1.4 cm charged to 10 nC,
the charge on the sphere can be calculated as follows:
q = 4 * pi * epsilon_0 * R * V
where epsilon_0 is the vacuum permittivity,
R is the radius of the sphere, and
V is the potential difference.
The radius of the sphere can be calculated as
R = 0.7 cm.
The potential difference can be calculated as
V = q / C,
where C is the capacitance of the sphere,
which can be calculated as
C = 4 * pi * epsilon_0 * R.
Substituting the values, we get:
q = 4 * pi * 8.854e-12 * 0.7 * 10e-9
V = q / (4 * pi * 8.854e-12 * 0.7)
The mass of an electron can be taken as 9.11e-31 kg. Substituting the values in the escape speed equation, we get:
v_escape = sqrt(2 * 8.98e9 * q / 9.11e-31)
v_escape=1.6 x 10^6 m/s
