At the lowest point of the curve, the motorcyclist's velocity would be tangential to the curve.
Motorcyclists' velocity would be parallel to the surface of the road. The acceleration of the motorcyclist would be directed opposite the direction of the velocity, meaning it would be directed uphill.
At the lowest point of the curve, the direction of the net force on the driver, Fn, would be directed towards the center of the curve. This is because the velocity of the driver is tangential to the curve, and the centripetal force is directed toward the center of the curve to provide the necessary acceleration to keep the driver on the curve.

at what minimum speed must a roller coaster be traveling when upside down at the top of a circle (fig. 42) so that the passengers do not fall out? assume a radius of curvature of 7.6 m.
The minimum speed at which the roller coaster must be traveling when upside down at the top of a circle so that the passengers do not fall out is approximately 8.7 m/s.
To determine the minimum speed at which a roller coaster must be traveling when upside down at the top of a circle so that the passengers do not fall out, we need to use the formula for centripetal force:
Fc = mv2/r
Where Fc is the centripetal force, m is the mass of the object, v is the velocity of the object, and r is the radius of the circle.
In this case, the centripetal force is equal to the weight of the passengers (mg), the mass is the mass of the passengers, the velocity is the minimum speed at which the roller coaster must be traveling, and the radius is the radius of curvature of the circle (7.6 m).
So we can plug in the values and solve for v:
mg = mv2/7.6
v2 = 7.6g
v = √(7.6g)
v ≈ 8.7 m/s
Therefore, the minimum speed at which the roller coaster must be traveling when upside down at the top of a circle so that the passengers do not fall out is approximately 8.7 m/s.

carbon-14 is used to date a palm fossil that originally contained 0.24 grams of carbon-14. The half life is 5700 years. If the fossil is found to be 17,000 years old, how much Carbon-14 does it contain now?
Answer:
Exactly 0.03042 carbon-14 is remaining.
Roughly 0.03 Carbon-14 is remaining. (When/If Multiple Choice)
Explanation:
Not a physics question, this is chemistry, but I'll answer.
First, divide 17,000/5700 to find the t, or time.
t = 2.98245614 or 2.98.
If it originally contained .24 grams, and a half life means x/2,
you would use the formula x/2^p, with p being the number of half lives
(these variables are made up, you can use any you would like)
In 17,000 years, the palm fossil experienced 2.98 half lives.
Thus meaning, using our equation, we would find (.24)/2^2.98
This equals 0.030418784 carbon-14 remaining to be exact.
(For Multiple Choice, it may be required to round to For Multiple Choice, it may be required to round to 3, so .24/2/2/2 or .24/2=.12 then .06 then it equals : .03 Carbon-14)
Blue light has a wavelength of 455 nm. What would be the frequency?
Answer:
f= 6.59x10^14
Explanation:
please see attached and don't forget to rate if it helps
Blue light has a wavelength of 455 nanometers, then its frequency would be 6.5934 ×10¹⁴ Hertz.
What is Wavelength?It can be understood in terms of the distance between any two similar successive points across any wave for example wavelength can be calculated by measuring the distance between any two successive crests.
The wavelength is inversely proportional to the frequency of the wave as from the following relation.
C = νλ
where c is the speed of the light having a value of 3 ×10⁸ meters/second.
As given in the problem if Blue light has a wavelength of 455 nanometers, then we have to find out its wavelength,
speed of light = wavelength ×frquency
3 ×10⁸ meters/second = 455 ×10⁻⁹ ×frquency
frequency = 3 ×10⁸/455 ×10⁻⁹
=6.5934 ×10¹⁴

A group of students doing a physics experiment are studying the conservation of momentum. The experiment asks the students to use a bouncy ball to measure the momentum before and after a collision. The mass of the ball is given to the students (1 kg). The only items allowed to be used are a meter stick and a stopwatch. Three students have written their own notes for how they want to solve the problem of determining the conservation of momentum of the ball elastically colliding with a surface. Which is the best method to use
The best method to determine the conservation of momentum of the ball elastically colliding with a surface is to use the method outlined by Student 3.
Student 3's method likely involves measuring the initial velocity of the ball by dropping it from a known height and timing how long it takes to reach the surface using a stopwatch and the meter stick to measure the distance. Then, they would measure the rebound height of the ball after the collision and use the same process to calculate the final velocity. By comparing the initial and final velocities, they can calculate the momentum before and after the collision and determine if momentum is conserved.
This method is preferred because it directly measures the velocities and relies on the principle of conservation of momentum. It also utilizes the given materials (meter stick and stopwatch) effectively. Other methods may not provide accurate measurements or rely on assumptions that may introduce errors.

Once an answer is submitted, you will be unable to return to this part. A 150-kg crate D is suspended from a ring at Aby a length of rope. The crate is held in certain location by two blocks, B and C, which are attached to the ring at Aby rope segments wrapped around frictionless pulleys. You want to position the crate such that the angle that rope AC makes in a counterclockwise direction from the positive x-axis is 30° as shown. The mass of block B is 135 kg. The mass of block C is adjustable. You decide to calculate what the mass of block C needs to be in order to keep crate D in the desired position. You also want to calculate , which represents the angle that rope AB makes in a clockwise direction from the negative x-axis when crate D is in the desired position. X 00:36:18 180° Choose which value represents the mass of block C that would keep crate D In equilibrium. Choose which value represents the mass of block C that would keep crate D In equilibrium. Multiple Choice 280 kg 20 kg 784.8 kg 196.2 kg 111.74 kg
The value that represents the mass of block C that would keep crate D in equilibrium is 196.2 kg (Option D).
To determine of value that represents the mass of block C that would keep crate D in equilibrium, ee can begin by determining the tension in the ropes. Since the crate is held in a certain location by two blocks, the tension in the ropes should be equal. We can use this fact to calculate the tension in the ropes by assuming that they have the same magnitude.
In this case, let T be the tension in each rope segment. The forces acting on the system can be represented in the following free-body diagram:
For the x-direction: T sin 30° = T sin 60° + µg = 0
where µ is the coefficient of friction and g is the acceleration due to gravity. Since the pulleys are frictionless, µ = 0. Therefore, we can simplify the equation as follows:
T sin 30° = T sin 60°
Dividing both sides by T:
sin 30° = sin 60°/2
This gives us: T = (2/√3) mg where m is the total mass of the system and g is the acceleration due to gravity.
Substituting the given values, we obtain:
T = (2/√3) × 150 × 9.81 ≈ 1962 N
Next, we can use the law of the lever to calculate the mass of block C required to keep the crate in equilibrium. According to this law, the sum of the moments acting on the system must be zero. We can choose the point where the ring is attached to the rope as the pivot. This gives us the following equation:
(135 kg)(9.81 m/s²)(3 m) + (mC)(9.81 m/s²)(6 m) - (150 kg)(9.81 m/s²)(4.5 m) - (1962 N)(3 m) = 0
Simplifying: (135)(3) + (6mC) - (150)(4.5) - (1962)(3) = 0
Rearranging: 6mC = 150(4.5) + 1962 - 135(3)
6mC = 2127
mC ≈ 196.2 kg
Therefore, the value that represents the mass of block C required to keep crate D in equilibrium is approximately 196.2 kg. Thus, the correct option is D.

if an electron current is 3.5 x 10^19 electrons/s, what is the conventional current?
The conventional current is 5.6 A if an electric current is 3.5 × 10¹⁹
In electron flow, electrons flow from the negative terminal of a battery to the positive terminal. However, conventional current assumes that positive charges are flowing from the positive terminal to the negative terminal. Therefore, to convert from electron current to conventional current, we need to reverse the sign and magnitude of the charge.
The charge of one electron is approximately 1.6 × 10⁻¹⁹ C. Therefore, the total charge passing through a point in a circuit in one second is:
Q = (3.5 × 10¹⁹ electrons/s) × (-1.6 × 10⁻¹⁹ C/electron) = -5.6 A

Explanation:
If the velocity of the train is v=s/t, where s is the distance and t is time, then v=400/5=80m/s. To get the vertical component of the velocity we need to multiply the velocity v with a sin(α): Vv=v*sin(α), where Vv is the vertical component of the velocity and α is the angle with the horizontal.

the ground.
+ How tall was the cliff?
+ How far away from the base of the cliff did the box fall?
Based on the provided initial velocity; The cliff was approximately 143.1 meters tall., The box fell approximately 54 meters away from the base of the cliff.
How to solve the questions on velocity?To find the height of the cliff, we can use the following kinematic equation for vertical motion:
y = y0 + v0_yt + 0.5a_y*t⁻².
where:
y = final vertical position
y0 = initial vertical position (0, since we start from the top of the cliff)
v0_y = initial vertical velocity (0, since the box is shoved horizontally)
a_y = vertical acceleration (9.81 m/s², due to gravity)
t = time (5.4 seconds)
Plugging in the values, we get:
y = 0 + 05.4 + 0.59.815.4²
y = 0.59.8129.16
y = 4.90529.16
y = 143.1 m
To find how far away the box fell from the base of the cliff, we can use the following equation for horizontal motion:
x = x0 + v0_x*t
where:
x = final horizontal position
x0 = initial horizontal position (0, since we start from the edge of the cliff)
v0_x = initial horizontal velocity (10 m/s)
t = time (5.4 seconds)

A 20 g particle is moving to the left at 30 m/s. How much work must be done on the particle to cause it to move to the right at 30 m/s?
The work done on a 20g particle moving to the left at 30m/s to cause it to move to the right at the same speed is 18 J.
What is work?Work is a scalar physical quantity that is proportional to the distance moved by an object when an external force is applied to the object. It is defined as the product of force and the displacement of the object in the direction of the force, as well as the cosine of the angle between the force and displacement vectors. Work is given the SI unit of joules (J).
Formula to calculate work done:
W = F × d × cos(θ)
where W is work done, F is force, d is distance, θ is the angle between the force and displacement vectors.
In this case, we have a 20 g particle moving to the left at 30 m/s, so the force acting on it is given by:
F = ma
where m = 20 g = 0.02 kg and a = -30 m/s² (negative because it is moving to the left)
F = 0.02 kg × -30 m/s² = -0.6 N
Negative sign means that the force is acting towards the left.
We need to cause the particle to move to the right at 30 m/s, so we have to apply a force in the opposite direction. Therefore, the angle between the force and the displacement is 180°.
θ = 180°cos(180°) = -1
Therefore, the work done on the particle is given by:
W = F × d × cos(θ)
W = (-0.6 N) × (d) × (-1)
W = 0.6 d J
We want the final speed to be 30 m/s and the initial speed is also 30 m/s. So, the change in velocity, ∆v is 60 m/s (final velocity - initial velocity = 30 m/s - (-30 m/s) = 60 m/s).
We can find the displacement, d using the kinematic equation:
v² - u² = 2as
where v is the final velocity, u is the initial velocity, a is the acceleration, and s is the displacement.
s = (v² - u²) / 2a
Given that v = 30 m/s, u = -30 m/s, and a = F/m (from F = ma) = (-0.6 N) / 0.02 kg = -30 m/s² (negative because force is in the opposite direction), we have:
s = (30² - (-30)²) / (2 × -30) = 30 m
Therefore, the work done on the particle to cause it to move to the right at 30 m/s is given by:
W = 0.6 d J = 0.6 × 30 J = 18 J
Alternatively, we can also use the kinetic energy equation to find the work done, since the kinetic energy of the particle changes from negative to positive.
K.E. = (1/2)mv²
The initial kinetic energy, K.E.i = (1/2)(0.02 kg)(-30 m/s)² = 9 J
K.E.f = (1/2)(0.02 kg)(30 m/s)² = 9 J
The change in kinetic energy, ∆K.E. = K.E.f - K.E.i = 18 J
Therefore, the work done on the particle to cause it to move to the right at 30 m/s is 18 J.

D. 90%. approximately 90% of the world's commercial energy is furnished by fossil fuels.
Fossil fuels, including coal, oil, and natural gas, have been the primary sources of commercial energy for many years. As of my knowledge cutoff in September 2021, approximately 90% of the world's commercial energy is furnished by fossil fuels.
Fossil fuels are widely used in various sectors such as electricity generation, transportation, industrial processes, and heating. Their high energy density, abundance, and established infrastructure for extraction, distribution, and utilization have made them dominant in meeting global energy demands.
However, it's worth noting that there is a global effort to transition to more sustainable and renewable energy sources in order to reduce greenhouse gas emissions and mitigate climate change. The use of renewable energy sources such as solar, wind, hydro, and geothermal is increasing, aiming to diversify the energy mix and reduce reliance on fossil fuels. The percentage of energy provided by fossil fuels may evolve over time as these efforts continue.
