An 82.0-kg person rides on a carnival ride in a 45.0-kg basket supported by a single chain. When the ride reaches its top speed, the basket moves at a constant speed in a horizontal circle with a radius of 7.10 m. At this point, the chain supporting the basket is at a 45.0 angle to the vertical. A)At top speed, how large are the vertical and horizontal components of the tension in the chain? (Hint: The vertical component of the tension equals the weight it supports.) B) What is the magnitude of the centripetal acceleration of the basket and its passenger? C) What is the speed of the basket and its passenger? D) How long does it take the basket to make one complete circle?
Answers
The vertical component of the tension is 1,177.05 N while the horizontal component of the tension is 127.47 × 3.90² = 1,949.04 N.
The magnitude of the centripetal acceleration is 2.14 m/s².
What is the value of the vertical and horizontal components of the tension in the chain?A) The vertical component of the tension equals the weight it supports, which is the weight of the person plus the weight of the basket:
Weight = (82.0 kg + 45.0 kg) × 9.81 m/s²
Weight = 1,177.05 N
Therefore, the vertical component of the tension is 1,177.05 N.
To find the horizontal component of the tension, we can use the fact that the net force in the horizontal direction is zero when the basket is moving at a constant speed.
The only horizontal force is the component of the tension perpendicular to the radius, so:
The horizontal component of tension = centripetal force
Horizontal component of tension = (mass × centripetal acceleration)
Horizontal component of tension = (82.0 kg + 45.0 kg) × (v²/7.10 m)
Horizontal component of tension = 127.47 v² N
Setting these two components equal to each other gives:
1,177.05 N = 127.47 v² N
Solving for v gives:
v = 3.90 m/s
Therefore, the horizontal component of the tension is 127.47 × 3.90² = 1,949.04 N.
B) The centripetal acceleration is given by:
a = v²/r
a = (3.90 m/s)²/7.10 m
a = 2.14 m/s²
Therefore, the magnitude of the centripetal acceleration is 2.14 m/s².
C) The speed of the basket and its passenger is 3.90 m/s.
D) The time it takes the basket to make one complete circle is given by:
T = 2πr/v
T = 2π(7.10 m)/3.90 m/s
T = 12.9 s
Therefore, it takes the basket 12.9 s to make one complete circle.

A solid conducting sphere is given a positive charge Q. How is the charge Q distributed in or on the sphere?
(A) It is concentrated at the center of the sphere.
(B) It is uniformly distributed throughout the sphere.
(C) Its density decreases radially outward from the center.
(D) Its density increases radially outward from the center.
(E) It is uniformly distributed on the surface of the sphere only.
Answers
The charge Q is uniformly distributed throughout the sphere. The correct answer is (B)
When a solid conducting sphere is given a positive charge Q, the charge will distribute itself evenly throughout the surface of the sphere due to the repulsion of like charges. This is known as the "Faraday's ice pail experiment".
According to the principle of electrostatics, the charge on a conductor always resides on its surface and distributes itself in a way that the electric field inside the conductor is zero. Since the charge on a conductor always resides on its surface, it follows that the charge Q in this case must be uniformly distributed throughout the surface of the sphere.
Option (A) is not true because the charge is not concentrated at the center of the sphere. If the charge was concentrated at the center of the sphere, the electric field would not be zero inside the conductor, which contradicts the principle of electrostatics.
Option (C) and (D) are not true because the density of the charge does not change radially outward from the center. If the density decreased or increased radially outward, the electric field inside the conductor would not be zero, which again contradicts the principle of electrostatics.
Option (E) is not true because the charge is distributed throughout the entire volume of the sphere, not just on its surface. A solid conductor has free charges that can move throughout its entire volume, so the charge will distribute itself throughout the entire volume of the sphere until the electric field inside the conductor is zero.
Therefore, the correct answer is (B) it is uniformly distributed throughout the sphere.

Answers
It is to be noted that the electric field that has been induced is (-B₁ A/2\(\pi\)R)θ. This is obtained by using the vector units in the Cylindrical Coordinate System.
What are Cylindrical Coordinates?Cylindrical Coordinates are simply defined as a component of a coordinate system that is used to locate a location in space using its polar coordinates and vertical distance from the polar plane.
How is the induced field arrived at?The formula for Induced Electric Field is given as:
∫ E · dl = ∈
If we replace ∈ with -B₁A and 2\(\pi\)R for dl then
∫ E · dl = -B₁A. Thus, we can state that
E∫ dl = -B₁A
Replacing or substituting 2\(\pi\)R for ∫ dl ·E(2πR) = - B₁A
We can thus rearrange the equation to read:
E · E = (\(\frac{-B1A}{2\pi R}\))θ

if you hook up your voltage supply to run 2v across this resistor, what current do you expect to measure?
Answers
The answer to your question is that the current you expect to measure depends on the resistance of the resistor.
Ohm's law states that the current (I) flowing through a resistor is directly proportional to the voltage (V) across it and inversely proportional to the resistance (R) of the resistor, or I = V/R. Therefore, if you apply a voltage of 2V across a resistor with a known resistance value, you can calculate the expected current by using Ohm's law.
For example, if the resistor has a resistance of 10 ohms, the current you expect to measure would be I = V/R = 2/10 = 0.2 amperes or 200 milliamperes.However, if the resistance value of the resistor is not known, you can measure the current directly using a multimeter set to measure amperage. Simply connect the multimeter in series with the resistor and the voltage supply, and the current flowing through the circuit will be displayed on the multimeter.

The volume per second of a fluid flowing through a horizontal pipe of length l is given by kpa/n where k is constant, p is the excess pressure (force per unit area) a is the radius of the pipe and U is the frictional quantity of dimension MLT-1 by dimensions find the number x
Answers
According to the given statement the number x is 2. The number x represents the dimensions of the term p * a in the given equation.
By comparing the dimensions of both sides of the equation, we find that x is equal to 2.
The equation given is:
Volume per second = k * (p * a) / n
Where:
- k is a constant
- p is the excess pressure (force per unit area)
- a is the radius of the pipe
- n is the frictional quantity of dimension MLT⁻¹
To find the number x, we need to determine the dimensions of each term in the equation.
1. Dimension of Volume per second:
- Volume has the dimension L³ (length cubed)
- Time has the dimension T (time)
- Therefore, Volume per second has the dimension L³ / T
2. Dimension of k:
- The equation states that k is a constant. Constants are dimensionless.
3. Dimension of p * a:
- Pressure has the dimension M / (L * T² ) (mass divided by length and time squared)
- Radius has the dimension L (length)
- Multiplying pressure by radius results in the dimension M / (L * T² ) * L = M / (L² * T² )
4. Dimension of n:
- Given in the question, n has the dimension MLT⁻¹
(mass times length times time to the power of -1)
Now, we can equate the dimensions:
L³ / T = k * (M / (L² * T² )) * MLT⁻¹
Simplifying the dimensions:
L³ / T = k * M / (L² * T² ) * MLT⁻¹
L³ / T = k * M / L² * M / T² * L^-1 * T⁻¹
L³ / T = k * M² / L² * T⁻¹
To equate the dimensions, both sides of the equation must have the same dimensions. Therefore:
L³ / T = k * M² / L² * T⁻¹
Comparing the dimensions on both sides, we can conclude:
L³ / T = k * M² / L²* T⁻¹
The dimensions on the left side are L^3 / T, and the dimensions on the right side are (k * M²) / (L² * T).
Therefore, the number x is 2.
The number x represents the dimensions of the term p * a in the given equation.
By comparing the dimensions of both sides of the equation, we find that x is equal to 2.

after a totally inelastic collision, two objects of the same mass and initial speed are found to move away together at half their initial speed. find the angle between the initial ve- locities of the objects.
Answers
The angle between the initial velocities of the objects after a totally inelastic collision of two objects of the same mass and initial speed that move away together at half their initial speed is 60°
p = m v
p = Momentum
m = Mass
v = Velocity
Total initial momentum = Sum of initial momentum of two objects
Along x-direction,
Total initial momentum = m u cos θ + m u cos θ
Total initial momentum = 2 m u cos θ
Considering the object moves in + x direction after collision.
Total final momentum = ( m + m ) v
Total final momentum = 2 m u / 2
Total final momentum = m u
According to law of conservation of momentum, in +x direction,
Total initial momentum = Total final momentum
