a simple pendulum is 4.00 m long. (a) what is the period of small oscillations for this pendulum if it is located in an elevator accelerating upward at 6.00 m/s2?
Answers
The time period of the small oscillations for the simple pendulum is found to be 3.14 seconds.
The pendulum is located in an elevator that is accelerating upwards with an acceleration of 6m/s² and length of the pendulum is 4m.
Because the elevator is accelerating in the upper direction the net acceleration of the pendulum will be (10 + 6)m/s².
The period of small accelerations for this pendulum will be given by the relation,
T = 2π(l/a)
Where, l is the length of pendulum and a is the net acceleration.
Putting values,
T = 2π(4/16)
T = 2π(1/2)
T = π seconds.
T = 3.14 seconds.
So, the time period of this small oscillations for this pendulum is 3.14 second.

A Ford Shleby GT 500 has a horsepower of 760 hp. What is that is Watts? DO NOT include units - just the numeric answer. I QUESTION 15 An object of mass 100 kg is moved with an acceleration of 10 m/2, and goes fron an initial position of 10 m to a final position of 30 m. What work was done on the object? DO NOT include units - just the numeric answer.
Answers
the work done on the object is 20000 J.
The conversion factor from horsepower to watts is 1 hp = 746 watts.
Therefore, the Ford Shelby GT 500's horsepower of 760 hp can be converted to watts as follows:
760 hp × 746 watts/hp = 567760 watts
To convert horsepower to watts, you simply need to multiply the number of horsepower by the conversion factor of 746 watts/hp.So, the numeric answer for 760 hp in watts is 567760.
According to the work-energy principle, the work done on an object is equal to the change in kinetic energy. Mathematically, the work-energy principle can be represented as follows:
W = ΔKHere, W represents the work done on the object, and ΔK represents the change in kinetic energy of the object.
The change in kinetic energy can be calculated using the following formula:
ΔK = (1/2)mvf² - (1/2)mvi²
Here, m represents the mass of the object, vi represents the initial velocity of the object, and vf represents the final velocity of the object. In this case, the object is initially at rest (vi = 0), so the formula can be simplified to
:ΔK = (1/2)mvf²
Now, we can use the following kinematic equation to calculate the final velocity of the object:
vf² = vi² + 2ax
Here, a represents the acceleration of the object, x represents the displacement of the object, and vi represents the initial velocity of the object. Plugging in the given values, we get:
vf² = 0 + 2(10 m/s²)(30 m - 10 m)vf² = 400 m²/s²vf = 20 m/s
Now, we can plug in the values of m and vf to calculate the change in kinetic energy:
ΔK = (1/2)(100 kg)(20 m/s)²ΔK = 20000 JSo, the numeric answer for the work done on the object is 20000 J.

the ramp is u. What is the kinetic energy of the box at the bottom of the ramp?
Answers
Hi there!
We can use the work-energy theorem to solve.
Recall that:
\(E_i = E_f\)
The initial energy equals the final energy (Conservation of Energy). However, we must take into account energy dissipated due to friction in this instance.
The energy lost due to friction is equivalent to the work done by friction. Recall the following:
Normal force on an incline: \(N = Mgcos\theta\)Force due to friction: \(F_f = \mu N = \mu mgcos\theta\)The work due to a force is:
\(W = F \cdot d \\\)
Since the displacement is in the same direction as the force, the dot-product becomes Fd.
The work due to friction then becomes:
\(W_f = \mu mgdcos\theta\)
The work due to friction is SUBTRACTED from the initial potential energy.
Initial energy = GPE = mgh
Final energy = KE
Therefore:
\(\boxed{mgh - \mu mgdcos\theta = KE}\)

a non-uniform, 80-g, meter stick balances when the support is placed at the 51.0-cm mark. at what location on the stick should a 5.0-g tack be placed so that the stick will balance at the 50.0 cm mark?
Answers
The tack should be placed 17.0 cm from the left end of the meter stick so that it balances at the 50.0 cm mark.
To solve this, we can use the principle of moments for rotational equilibrium.
As the location around which we will compute the moments, let's select the left end of the meter stick. The moment caused by the weight of the meter stick at the support's placement is:
M1 = (80 g) × (51.0 cm) = 4080 g·cm
The weight moments of the meter stick and the tack must be equal and opposite of each other in order for the meter stick to balance at the 50.0 cm point. Call the length between the meter stick's left end and the tack "x" distance. When the tack is heavy, this happens:
M2 = (5 g) × (x cm)
The moment due to the support is:
M3 = (80 g + 5 g) × (50.0 cm - x)
Setting M1 + M2 = M3 and solving for x, we get:
(80 g)(51.0 cm) + (5 g)(x cm) = (80 g + 5 g)(50.0 cm - x)
4080 g·cm + 5x cm·g = 4250 g·cm - 75 g·cm - 5x cm·g
10x cm·g = 170 g·cm
x = 17.0 cm
∴, the tack should be placed 17.0 cm from the left end of the meter stick so that it balances at the 50.0 cm mark.

a sound wave leaves its source to travel through the liver and a reflected wave returns 2 microsecond later. what is the distance from the source to the reflector?
Answers
To solve this problem, we need to know the speed of sound in the liver. The speed of sound varies depending on the medium it is traveling through. In human tissues, it's typically around 1540 m/s, but it can vary slightly.
Once we have the speed of sound, we can use the formula for distance, which is speed multiplied by time. However, since the sound wave travels to the reflector and back, the time we have is actually twice the time it takes for the sound wave to reach the reflector. Therefore, we need to divide the total time by 2 to get the time it takes for the sound wave to reach the reflector.
Let's use these values to calculate the distance.
The distance from the source to the reflector is approximately 1.54 millimeters (mm).
This is calculated by using the speed of sound in the liver (1540 m/s) and the time it takes for the sound wave to reach the reflector (1 microsecond, which is half of the total time of 2 microseconds). The formula for distance is speed multiplied by time, so the calculation is 1540 m/s * 1 microsecond = 0.00154 meters, or 1.54 mm.

In a space with hyperbolic geometry, the behavior of parallel lines differs from that of Euclidean geometry.
In hyperbolic space, parallel lines diverge from each other as they extend further.If two initially parallel flashlight beams traverse billions of light-years of space in a hyperbolic geometry, they will gradually diverge from each other. The divergence between the beams will increase as they travel a greater distance.
This phenomenon is a consequence of the non-Euclidean geometry of space. In hyperbolic space, the curvature causes parallel lines to "spread out" or diverge. The extent of the divergence will depend on the specific curvature of the space and the distance traveled.

because of the massive weight, the distance needed to stop an average train travelling at 55mph is
Answers
The distance needed to stop an average train traveling at 55 mph (miles per hour) depends on several factors, including the train's mass, speed, braking system, and track conditions. The braking capabilities of the train play a crucial role in determining the stopping distance.
On average, it is estimated that a typical freight train traveling at 55 mph may require a distance of approximately one mile (1.6 kilometers) to come to a complete stop. This estimate takes into account the train's weight, momentum, and the time required for the braking system to bring the train to a halt.
However, it is important to note that this is a rough estimate and can vary based on various factors such as the train's specific configuration, the condition of the track, the effectiveness of the braking system, and the operator's skill. Additionally, trains may be equipped with additional systems such as emergency brakes to assist in stopping in shorter distances when necessary.

(b) The aspect of Student's (2) reasoning that is correct is that the shorter piece of string will always break first, however, the statement is only true for sudden pull due to the increased force experienced by the shorter string from a more rapid change in momentum
(c) The aspect of Student 1's statement that is incorrect is the that the upper string will always break first
The aspect of Student 2's statement that is incorrect is the that the shorter piece of string will always break first
(d) A string will break when subject to a force equivalent to its breaking force. The force experienced by the string increases as the rate of pull (suddenness) increases and the suddenness increases inversely with the length of the string, as such the shorter lower string will break first from a sudden pull before the force of the pull is completely transmitted to the upper string. Whereby the lower string is slowly pulled, the force is evenly transmitted to the upper string which is then taking up the load of the weight and the applied force together and is likely to break first

A cheetah is known to be the fastest mammal on Earth, at least for short runs. Cheetahs have been observed running a distance of 5.50 × 102 m with an average speed of 1.00 × 102 km/h.
How long would it take a cheetah to cover this distance at this speed?
Answers
The cheetah needs 197.8 seconds to complete the 5.50 *100 m distance.
The distance traveled divided by the time taken is the most popular formula for calculating average speed. The average speed is determined by dividing the whole distance by the total time required to complete the distance. The other calculation, provided you have the initial and final speeds, adds them together and divides by 2.20. calculating the time needed for a cheetah to travel 5.50 102 meters.
10 km/h average speed is equal to 10 / 3.6, or 2.78 m/s.
Dist. = 5.50 102
