a hoop and a cylinder of equal mass roll down a ramp with height h. which has greater speed at the bottom of the ramp?
a. solid sphere
b. cylinder
c. all speeds are equal
d. hoop

Answer:

Mass, m of gas is 0.2504 grams.

Explanation:

First, we need to solve for the volume of the cylindrical tube.

Volume of cylinder is given by the formula;

\( V = 2\Pi r^{2}h\)

Where, V represents volume.

π represents pie

r represents radius.

h represents height or length.

Given the following data;

Radius, r = 1.5cm

Length, h = 14.4cm

Density, d = 0.00123g/cm³

Substituting into the equation;

\( V = 2 * 3.142 * (1.5)^{2}14.4\)

\( V = 2 * 3.142 * 2.25 * 14.4\)

\( V = 203. 6016\)

Therefore, the volume of the cylindrical tube is 203. 6016cm³

Density can be defined as mass all over the volume of an object.

Simply stated, density is mass per unit volume of an object.

Mathematically, density is given by the formula;

\(Density = \frac{mass}{volume}\)

\( Mass = density * volume \)

Substituting into the equation, we have;

\( Mass = 0.00123 * 203. 6016 \)

Mass = 0.2504g.

The best way to calculate the volume of a log with a serious defect is to calculate the volume of the defect and subtract it from the total volume of the log which is denoted as option C.

This is referred to as the amount of space occupied by any three-dimensional solid which could be a square, rectangle etc.

In a scenario where a defect is present in the log, then it is  best to consider it by first calculating the volume of the defect after which it is then subtracted from the total volume of the log in other to give an accurate result.

Answer:

If there are two opposite and equal forces, then the object that has force exerted on it will not move. The students can make it move if they both push on one side.

The box is not moving because the students are pushing in equal force and opposite direction to each other and the net force on box becomes 0.

One way student can move it is if they push the box  in same direction.

The push or pull of an object is force and the direction in which object moves is the direction of force.

(a) The free-body diagram of the beam with the woman standing x-meters to the right of the first pivot is shown below:

Beam Diagram

(b) The woman is the furthest to the right when the normal force F⃗ N 1 is the greatest. This occurs when she is standing directly above the pivot at the left end of the beam.

(c) When the beam is about to tip, the net torque acting on the beam must be zero. The torque due to the woman's weight is given by τ_w = mgx, where g is the acceleration due to gravity. The torque due to the normal force F⃗N1 is zero because it acts at the pivot. Therefore, we have:

τ_net = τ_w - F_N2*l/2 = 0

Solving for F_N1, we get:

F_N1 = (mgx)/(L-l/2)

When the beam is about to tip, the normal force F⃗N1 is at its maximum value.

(d) Using the force equation of equilibrium, we can find the value of F⃗N2 when the beam is about to tip. The sum of the vertical forces must be zero, so we have:

F_N1 + F_N2 - Mg - mg = 0

Substituting the expression for F_N1 from part c), we get:

F_N2 = Mg + mg - (mgx)/(L-l/2)

(e) Using the result from part c) and the torque equilibrium equation, we can find the woman's position when the beam is about to tip. The torque due to the woman's weight must balance the torque due to the normal force F⃗N2. Therefore, we have:

mgx = F_N2*(L-x)

Substituting the expression for F_N2 from part d), we get:

mgx = (Mg + mg - (mgx)/(L-l/2))*(L-x)

Solving for x, we get:

x = (L*(M+m) - lm)/(2M + 2m - (2m*L)/(L-l))

Substituting the given values, we get:

x = 4.31 m

Therefore, the woman's position when the beam begins to tip is 4.31 meters to the right of the left pivot.

(f) We can check our answer by using a different axis of rotation. Let's choose the pivot at the right end of the beam as the axis of rotation. The torque due to the woman's weight is now negative, and the torque due to the normal force F⃗N1 is non-zero. Therefore, we have:

τ_net = -mg(L-x) + F_N1*l/2 = 0

Solving for F_N1, we get:

F_N1 = (2mgL - 2Mgx - mgl)/(2*l)

Substituting the given values, we get:

F_N1 = 594.0 N

This is the same value we obtained in part (c). Therefore, our answer is consistent with the laws of physics

The typical television remote control emits radiation with a wavelength of 938 nm having a frequency of \(3.20 \times 10^{14} s^{-1}\).

The frequency of this radiation can be determined using the formula λν = c, where λ is the wavelength, ν is the frequency, and c is the speed of light in a vacuum.

The speed of light is approximately 3.00 × 10^8 m/s. The wavelength of the radiation in meters is given by:

938 nm = 938 × 10^-9 m
So, λ = 938 × 10^-9 m.

Substituting this value and the value of c in the formula, we have:
938 × 10^-9 m × ν = 3.00 × 10^8 m/s

Solving for ν gives:
ν = (3.00 × 10^8 m/s) / (938 × 10^-9 m) = 3.20 × 10^14 s^-1

Therefore, the frequency of the radiation emitted by the typical television remote control is 3.20 × 10^14 s^-1 (or Hertz).

Explanation:

Answer:

Simply put: the grounding wire is a way of electrical protection. Its function is to quickly connect the current to the earth through the grounding wire when your electrical equipment is leaking or inductively charged, so that the equipment shell is no longer charged, thereby ensuring the safety of the equipment behind the personnel.

Explanation:

For example, due to poor insulation performance of household appliances or humid environment, the shell will be charged with static electricity, and electric shock accidents may occur in serious cases. In order to avoid accidents, a wire can be connected to the metal shell of the electrical appliance, and the other end of the wire can be connected to the ground. Once the electrical leakage occurs, the grounding wire will bring static electricity into the ground and release it. In addition, it is more important for electrical maintenance personnel to use electric soldering irons to solder circuits, sometimes because the electric soldering irons are charged and break down and damage the integrated circuits in the electrical appliances. Friends who use computers sometimes ignore the grounding of the mainframe. In fact, connecting a ground wire to the mainframe of the computer can prevent the occurrence of crashes to a certain extent.

answer :  mass of Bananas ( m ) = \(\frac{A^2}{V^2} * K\)

To calculate for weight of Bananas  = m * g      where g = 9.8

Explanation:

Given an amplitude ( A )= 29.8981

Spring constant = x ( unknown )

maximum speed of Bananas( v ) = wA  ( unknown )

question : calculate the weight of the bananas

First  step : calculate the period of oscillation

T = \(\frac{2\pi }{vA}\) --- ( 1 )

next step : express T in terms of mass ( m ) of the bananas

= \(2\pi \sqrt{\frac{m}{k} } = \frac{2\pi }{vA}\)

∴ m/k = A^2 / v^2

hence  mass of Bananas ( m ) = \(\frac{A^2}{V^2} * K\)

Velocity = 4 m/s (constant)

Displacement =?

Next, we shall determine the change in time. This can be obtained as follow:

Time 1 = 3 s

Time 2 = 3.5 s

Change in time = 3.5 – 3

Change in time = 0.5 s

Finally, we shall determine the displacement of the bird between 3 s and 3.5 s as follow:

Velocity = 4 m/s

Time = 0.5 s

Displacement =?

Velocity = Displacement /Time

4 = Displacement /0.5

Cross multiply

Displacement = 4 × 0.5

Displacement = 2 m

Therefore, the displacement of the birth between 3 and 3.5 s is 2 m.

Both people will have the same magnitude of momentum. The total momentum of the two people after they push off each other will be zero. However, the larger person will experience a smaller acceleration than the smaller person due to their difference in mass.

When the two people push off each other, the total momentum of the system remains conserved.

This means that the sum of their individual momentums before the push must equal the sum of their momentums after the push. Since they start at rest, their initial momentums are zero, so their final momentums must also be zero. This means that the magnitudes of their momentums are equal but opposite in direction.

However, the acceleration experienced by each person is given by the force exerted on them divided by their mass. Since the force on each person is equal and opposite, the acceleration experienced by the larger person will be smaller than that of the smaller person due to their difference in mass. This is described by Newton's Second Law, F=ma, where the force F is constant but the acceleration a is inversely proportional to mass m.
