The speed of object A at the end of the ramp is approximately 25.39 m/s.

Part (a) The two objects, A (solid cylinder) and B (hollow cylinder), will reach the bottom of the ramp at the same time.

The time it takes for an object to reach the bottom of a ramp depends on its mass distribution and shape, not on whether it is solid or hollow.

In the absence of any other information, we can assume that both objects have similar mass distributions and roll without slipping, resulting in them reaching the bottom of the ramp simultaneously.

Therefore, the answer is 3) They will reach the bottom at the same time.

Part (b) To calculate the speed of object A at the end of the ramp, we can use the principle of conservation of energy.

The potential energy at the beginning of the ramp is converted into kinetic energy at the bottom of the ramp.

The potential energy (PE) at the beginning of the ramp is given by:

PE = m * g * h

where m is the mass of object A, g is the acceleration due to gravity, and h is the height of the beginning of the ramp.

Mass of object A (m) = 340 g = 0.34 kg

Radius of object A (r) = 31 cm = 0.31 m

Height of the beginning of the ramp (h) = 41 cm = 0.41 m

Acceleration due to gravity (g) = 9.8 m/s²

The potential energy at the beginning of the ramp is:

PE = 0.34 kg * 9.8 m/s² * 0.41 m

PE ≈ 1.375 J

At the bottom of the ramp, the potential energy is fully converted into kinetic energy:

KE = 1/2 * I * ω²

where I is the moment of inertia of the object and ω is the angular velocity.

For a solid cylinder, the moment of inertia is given by:

I = (1/2) * m * r²

Substituting the given values:

I = (1/2) * 0.34 kg * (0.31 m)²

I ≈ 0.0169 kg·m²

Since the object rolls without slipping, the linear speed (v) can be related to the angular velocity (ω) by the equation:

v = ω * r

Solving for ω:

ω = v / r

The linear speed at the end of the ramp is equal to the radius times the angular velocity.

Substituting the values:

v = (1.375 J / 0.0169 kg·m²) * 0.31 m

v ≈ 25.39 m/s

Explanation:

GOT IT RIGHT

If a 1.50-kg mass is acted upon by a force of 16.0 N applied at an angle of 60° above the horizontal. The acceleration of the mass is approximately 5.33 m/s². Therefore, the correct option is (B) 5.33 m/s².

The given force applied at an angle of 60° is 16 N. The mass of the object is 1.50 kg. We need to calculate the acceleration of the mass. The force is resolved into two components. One component is parallel to the surface and another one is perpendicular to the surface.

We can calculate the parallel and perpendicular components as:

F⊥= F sin θ = 16 sin 60° = 13.86 N.

F|| = F cos θ = 16 cos 60° = 8 N.

Here, F⊥ is the perpendicular force and F|| is the parallel force. So, the perpendicular force acting on the mass is 13.86 N and the parallel force acting on the mass is 8 N. Now we can calculate the acceleration of the mass as:

Net force acting on the object, F = F|| = 8 N. Using Newton's second law of motion, we have:

ma = F ⇒ a = F/m.

Using this value of F and m, we get the acceleration as a = 8 N/1.50 kg ≈ 5.33 m/s². Hence, B is the correct option.

Explanation:every body said

Yes, the electron can be further away than 1 angstrom from the nucleus in a hydrogen atom. In quantum mechanics, the electron's position is described by a probability distribution, allowing for occasional excursions beyond the average radius.

The radius of 1 angstrom represents an estimate of the average distance between the electron and the nucleus in the ground state of a hydrogen atom. However, in quantum mechanics, the electron's position is described by a probability distribution rather than a fixed orbit.

This means that there is a non-zero probability of finding the electron at distances greater than 1 angstrom from the nucleus, although the probability decreases as the distance increases. Therefore, while the average distance may be 1 angstrom, the electron can occasionally be found further away from the nucleus.

Percentage of the vehicle's kinetic energy is stored in the wheels is 9.64%

Kinetic energy is the energy possessed by the object due to its motion. [ It is defined as the work required to accelerate a body of specified mass from rest to a specified velocity. After the body acquires this energy during acceleration, it retains this kinetic energy as long as the velocity does not change. The same work is done when the body slows down from its current speed to rest. Formally, kinetic energy is any term in the Lagrange of a system that includes the time derivative.

 In relativistic mechanics, this is a good approximation only if v is much smaller than the speed of light. The standard unit for kinetic energy is the joule, while the British unit for kinetic energy is the foot-pound.

I = rg2*m

rotational KE of wheels  = 0.5Iω2= 0.5(rg2*m)*(v/r)2

To select the most economical W shape for a beam using A992 steel, we need to compare designs using both the LRFD (Load and Resistance Factor Design) and ASD (Allowable Stress Design) methods.

a. For Load and Resistance Factor Design, first determine the factored loads by applying appropriate load factors to the service loads. Next, choose an initial W shape and check if the design strength of the selected shape meets or exceeds the factored loads. Iterate this process by considering different W shapes until you find the most economical shape that meets the design requirements.

b. For Allowable Stress Design, determine the allowable loads by dividing the service loads by the corresponding load factors. Then, follow a similar procedure as in LRFD to find the most economical W shape that meets the design requirements.

In both cases, remember that the beam weight is not included in the service loads shown. To identify the most economical W shape overall, compare the designs obtained using LRFD and ASD and choose the one with the lowest cost or weight.

Answer:

C. 199.9 s

Explanation:

3 minutes = 3×60 = 180 seconds.

the turtle moves in that time 180×10 = 1800 cm.

in other words the rabbit gave it that much head-start (it does not matter if that was at the begin of in the middle of the race).

the rabbit moves with 10×10cm/s = 100cm/s.

the rabbit needs therefore 1800/100 = 18 seconds for the

1800 cm.

at that time the turtle has added another 18×10 = 180 cm.

for which the rabbit needs 180/100 = 1.8 seconds.

during that time the turtle has added 1.8×10 = 18 cm.

and so on.

in formal mathematics this looks like this :

1800 + 10x = 100x

after x seconds of the rabbit running both will have run the same distance, and it is a tie.

1800 = 90x

x = 20 seconds

so, at that point, the rabbit was actively running for 20 seconds and raced 20×100 = 2000 cm

and the turtle was actively running for 180 + 20 = 200 seconds, and also covered 200×10 = 2000 cm.

but our question tells us that the turtle won by 10 cm.

so, the race was over a little bit before these 200 seconds (for a tie).

this means, the rabbit could not run the last 10 cm for the tie (because the race was over and the turtle had won).

the rabbit would have needed 10/100 seconds for these 10 cm.

as speed = distance/time

we need to divide distance by speed

distance/1 / distance/time

to get time.

so,

10cm/1 / 100cm/s = 10s/100 = 1/10 s

so, we need to deduct this 1/10 s from the 200 seconds of the turtle (and also from the 20 seconds for the rabbit).

the race lasted of course the whole time the turtle was running (while the rabbit was resting, officially still participating in the race with speed 0 for 3 minutes).

and so, the race was 199.9 s long.

The resistance of the person is 9200 Ω if a fault in the switch is caused by a householder to receive a mild electric shock with the mean power transfer to the person as 5.75 W and potential difference across the person as 230 V.

The resistance of the person can be calculated using Ohm’s law.

Ohm’s law states that the potential difference across a conductor is directly proportional to the current flowing through it, provided that its temperature and other physical conditions remain constant.

It can be expressed as: V = IR,

where V is the potential difference, I is the current, and R is the resistance of the conductor.

Rearranging the equation, we get: R = V/ I.

Given that the mean power transfer to the person was 5.75 W and the potential difference across the person was 230 V, the current flowing through the person can be calculated using the formula:

P = IV

where P is the power ,V is the potential difference and I is the current flowing through the person

Rearranging the equation, we get: I = P/V

Substituting the given values, we get:

I = 5.75/230 = 0.025 A

Therefore, the resistance of the person can be calculated as:

R = V/I = 230/0.025 = 9200 Ω

Hence, the resistance of the person is 9200 Ω.

Answer: The rocket will have traveled 1050 Km

Hope this help ☺

After 1.5 hour the rocket will have traveled 1023.54 km.

In everyday use and in kinematics, the speed (commonly referred to as v) of an object is the magnitude of the change of its position over time or the magnitude of the change of its position per unit of time; it is thus a scalar quantity.  SI unit of speed is meter/second.

Initial speed of the rocket = 700 km/hr

= 700 (1000/3600) meter/second

= 194.44 meter/second

Acceleration due to gravity is = 9.8 m/s²

Time interval is = 1.5 hour = 1.5 × 60 × 60 second

hence, after 1.5 hour the rocket will have traveled = (194.44) (1.5 × 60 × 60) - 1/2×9.8×(1.5×60×60)² meter

= 1050000 meter - 26460 meter
