which would best be explained using newton's third law?question 15 options:a larger engine allows a car to accelerate faster.a bicyclist coasts down from the top of a hill.a car stops short and the passenger moves forward.a gun moves backward while firing a bullet.
Answers
the best explanation using Newton's third law is the gun moving backward while firing a bullet.
Newton's third law of motion states that for every action, there is an equal and opposite reaction. In the case of the gun firing a bullet, when the bullet is expelled from the barrel, it exerts a forward force on the bullet. Simultaneously, according to Newton's third law, the gun experiences an equal and opposite backward force (recoil). This backward motion of the gun is a result of the action-reaction pair.
In the other options:
- A larger engine allowing a car to accelerate faster can be explained by Newton's second law, which states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.
- A bicyclist coasting down from the top of a hill can be explained by the conservation of energy and the force of gravity acting on the cyclist.
- When a car stops short and the passenger moves forward, it can be explained by Newton's first law, also known as the law of inertia. The passenger tends to continue moving forward due to inertia until an external force (such as a seatbelt or airbag) acts on them to stop their motion.

what is the wavelength of visible light that has a frequency of 2.1 x 1014 hz? enter the result in nm (nanometers). you may round to the nearest integer.
Answers
For a visible light that has a frequency of 2.1 x 1014 Hz, the wavelength is approximately 1430 nm.
To calculate the wavelength of visible light with a frequency of 2.1 x 10^14 Hz, we can use the formula:
Wavelength (λ) = Speed of light (c) / Frequency (f)
The speed of light (c) is approximately 3.0 x 10^8 meters per second (m/s). So, we can plug in the given frequency (f) into the formula:
Wavelength (λ) = (3.0 x 10^8 m/s) / (2.1 x 10^14 Hz)
Wavelength (λ) ≈ 1.43 x 10^-6 meters
Now, to convert this to nanometers (nm), we multiply by 10^9:
Wavelength (λ) ≈ 1.43 x 10^3 nm
Rounded to the nearest integer, the wavelength is approximately 1430 nm.

An astronaut's boots weigh 100 N on Earth where the acceleration of free fall is 10 m/s2. How much will they weigh on Mars where the acceleration of free fall is 4 m/s2 ?
Answers
Answer:
To solve this problem, we can use the formula for weight:
W = m * g
where W is the weight, m is the mass, and g is the acceleration due to gravity. Since we are given the weight of the boots on Earth, we can solve for the mass as follows:
W = m * g
100 N = m * 10 m/s^2
m = 10 kg
Now we can use the mass to calculate the weight on Mars using the same formula but with the acceleration due to gravity on Mars:
W = m * g
W = 10 kg * 4 m/s^2
W = 40 N
Therefore, the boots would weigh 40 N on Mars where the acceleration of free fall is 4 m/s^2.

Dr. Chang is studying seismic waves. He notices that seismic waves (a type known as p-waves) travel faster through the mantle than through the outer core. What can he conclude from this observation?.
Answers
Seismic velocities are influenced by the medium's physical characteristics, including composition, mineral phase and packing structure, temperature, and pressure.
Denser materials allow seismic waves to propagate more quickly, hence depth generally increases the speed of seismic waves. Seismic waves are slowed in abnormally hot regions. A liquid conducts seismic waves more slowly than a solid does. Due to the fact that P waves and S waves cannot propagate through liquid, molten regions of the Earth slow P waves and block S waves.
There are two different types of waves produced by earthquakes: primary (P) and secondary (S). Based on when they come and how they feel on the surface, they are classified.

Nuclear decay occurs according to first-order kinetics. Argon-37 decays with a rate constant of 0. 0198 days–1. After 98. 3 days, a sample has a mass of 2. 14 g. What was the original mass of the sample?.
Answers
The original mass of the Argon-37 sample (N₀) was 14.98651g or approximately 15g. We Use the equation for first-order kinetics for determining the original mass of the given Argon-37 sample.
What is first order rate equation?If the rate of radioactive decay is first order, we can write r = k[N]1, where N is the quantity of radioisotope present at the time the rate is recorded, k is the isotope's first order rate constant, and r is the rate of decay as observed.
According to First-Order Rate Equation,
\(ln(\frac{N}{N_{0} } )=-kt\)
Here,
N = The amount of radioisotope left after "t" time.
N₀= The initial amount of radioisotope,
k = Rate constant of the radioisotope.
t = Time
Given,
N = 2. 14 g.
N₀ = ?
k = 0. 0198
t = 98. 3 days
Now, substituting these values in the first order rate equation we get,
\(ln(\frac{N}{N_{0} } )=-kt\\ln(\frac{2.14}{N_{0} } )=-0.0198*98.3\\ln(\frac{2,14}{N_{0} } )=-1.94634\\\frac{2.14}{N_{0} } =e^{-1.94634} \\\frac{2.14}{N_{0} }=0.142795\\N_{0} = 14.98651g\)
Hence, the original mass of the sample (N₀) was 14.98651 g or approximately 15 g.

magnitude and direction.
a. The drawing of the vector extending from point (0, 0) to (190, 0) on the coordinate plane is attached.b. The velocity vector extending from (0, 0) to (108.76, 50.714) on the coordinate plane is attached.c. The displacement vector extending from (0, 0) to (30·√2, 30·√2) is attached.Reasons:
a. The magnitude of the vector = 190 N
The direction in which the vector acts = East
Therefore, in vector form, we have;
\(\vec{F}\) = 190 × cos(0)·i + 190 × sin(0)·j = 190·i
The vector can be represented by an horizontal line, 190 units long
Coordinate points on the vector = (0, 0) and (190, 0)
The drawing of the vector with the above points using MS Excel is attached.
b. Magnitude of the velocity vector = 120 km/hr. 25° North of east
Solution;
The vector form of the velocity is; \(\vec{v}\) = 120 × cos(25)·i + 120×sin(25)·j, which gives;
\(\vec{v}\) = 120 × cos(25)·i + 120×sin(25)·j ≈ 108.76·i + 50.714·j
\(\vec{v}\) ≈ 108.76·i + 50.714·j
Therefore, points that define the vector are; (0, 0) and (108.76, 50.714)
The drawing of the vector is attached
c. The magnitude of the vector = 60 m
The direction of the vector is southwest = West 45° south
The vector form of the displacement is \(\vec{d}\) = 60 × cos(45°)·i + 60 × sin(45°)·j
Which gives;
\(\vec{d}\) = 30·√2·i + 30·√2·j

Answers
The little youngster must sit 4.99m away from the pivot point in order to balance himself.
Given mass of small child (m1) = 23kg
mass of larger child (m2) = 41kg
pivot is at the center of seesaw.
distance larger child sits from the pivot (r2) = 2.8m
distance of small child fom pivot = r1
Since they should be in static equilibrium, they are pulling in opposite directions with torques of the same magnitude.
The clockwise torque and the anticlockwise torque must be equal.
By conservation of momentum we say τ1 = τ2
where τ = mgr here r is the distance from the pivot
So m1gr1 = m2gr2
23 x 9.8 x r1 = 41 x 9.8 x 2.8

Express 48 m/s in terms of
1.km/h
2.m/min
3.km/s
4.km/minutes
Answers
48 m/s in terms of km/h is 720.8 km/h. In terms of m/min is 2880 m/min, in terms of km/s is 0.048 km/s and in terms of km/min is 2.88 km/min.
To solve this question, we need to understand some terms. The unit of velocity is measured in m/s. It can be expressed in different units of velocity.
1 km (kilometer) = 1000 meter
1 h (hour) = 3600 seconds
1 minutes = 60 seconds
To convert m/s into km/h,
48 m/s * 3600/1000 = 172.8 km/h
To convert m/s into m/min,
48 m/s * 60 = 2880 m/min
To convert m/s into km/s,
48 m/s ÷ 1000 = 0.048 km/s
To convert m/s into km/minutes,
48 m/s * 60 / 1000 = 2.88 km/min
Therefore, the 48 m/s expressed is 172.8 km/h, 2880 m/min, 0.048 km/s and 2.88 km/min.
To know more about velocity and conversions,
https://brainly.com/question/21552920
48 m/s is equivalent to 172.8 km/h, 2880 m/min, 0.048 km/s, and 2.88 km/minute.
To express 48 m/s in different units of velocity:
km/h (kilometers per hour):
To convert m/s to km/h, we can use the conversion factor of 3.6 since 1 m/s is equal to 3.6 km/h.
48 m/s * (3.6 km/h / 1 m/s) = 172.8 km/h
Therefore, 48 m/s is equivalent to 172.8 km/h.
m/min (meters per minute):
To convert m/s to m/min, we can use the conversion factor of 60 since there are 60 seconds in a minute.
48 m/s * (60 m/min / 1 s) = 2880 m/min
Therefore, 48 m/s is equivalent to 2880 m/min.
km/s (kilometers per second):
Since 1 kilometer is equal to 1000 meters, to convert m/s to km/s, we divide the value by 1000.
48 m/s / 1000 = 0.048 km/s
Therefore, 48 m/s is equivalent to 0.048 km/s.
km/minute (kilometers per minute):
To convert m/s to km/minute, we first need to convert m/s to km/s (as calculated in the previous step) and then multiply by 60 to convert seconds to minutes.
0.048 km/s * 60 = 2.88 km/minute
So, 48 m/s is equivalent to 2.88 km/minute.
Hence, 48 m/s is equivalent to approximately 172.8 km/h, 2880 m/min, 0.048 km/s, and 2.88 km/minute.

What is the acceleration at the end of a test tube that is 10 cm from the axis of rotation?
Answers
The acceleration at the end of a test tube that is 10 cm from the axis of rotation in a centrifuge rotating at 3300 rpm is 1.2 × 10⁴ m/s².
To calculate the acceleration, we first need to convert the rotational speed from revolutions per minute (rpm) to radians per second (rad/s). We can do this by multiplying the rotational speed by 2π/60, which is the conversion factor between revolutions and radians per second,
3300 rpm × 2π/60 = 346.41 rad/s
Next, we can calculate the centripetal acceleration using the formula a = rω^2, where r is the radius and ω is the angular velocity. Since the test tube is 10 cm from the axis of rotation, or 0.1 meters, we have:
a = rω² = (0.1 m) × ω²
a = (0.1 m)(346.41 rad/s)² = 1.2 × 10^4 m/s²

1. The low-speed lift coefficient for a NACA 2412 airfoil is 0.65 at an angle of attack of 4º. Using the Prandtl-Glauert Rule, calculate the lift coefficient for a flight Mach number of 0.75.
Answers
The Prandtl-Glauert Rule predicts that the lift coefficient for a NACA 2412 airfoil at a Mach number of 0.75 will be approximately 0.938.
The Prandtl-Glauert Rule is used to correct for the effects of compressibility on lift coefficients at transonic speeds (Mach numbers near 1). It states that the lift coefficient can be approximately calculated by dividing the actual lift coefficient at the given angle of attack and Mach number by thec square root of 1 - (Mach number)^2.
Using the given data, the actual lift coefficient at Mach 0.75 can be estimated by dividing the low-speed lift coefficient of 0.65 by the square root of 1 - (0.75)^2, which gives a lift coefficient of approximately 0.938.

Two infinite positively-charged conducting surfaces are spaced a distance d apart and generate electric fields E1 and E2 respectively. What is the net electric flux through a square having sides of length a that is located 1/3 of the distance between the left and right surfaces?
Answers
The electric flux through a square having sides of length a that is located 1/3 of the distance between the left and right surfaces can be calculated as follows Now, consider the following two statements:
In a static equilibrium situation, there can be no electric field inside the conductor. Let us consider the segment AB of the surface1 such that point A is at the edge of the square and point B is in the middle of the segment joining the two surfaces. Since the surface is at the same potential, the potential difference between A and B is zero. Let C be the point where the perpendicular bisector of AB meets the surface2. .
By statement 2, there is no electric field inside the conductor and hence there is no potential difference inside the conductor. Therefore, the potential difference between A and C is equal to the potential difference between B and C which is of the potential difference between the surfaces. Let the potential difference between the surfaces be V.
