Yes, it can be concluded that the population mean completion time using the new process is less than 75 minutes at the 0.10 level of significance.

To determine if there is a significant difference in the mean completion time using the new process, a one-sample t-test can be conducted. The null hypothesis (H0) states that the population mean completion time is equal to 75 minutes, while the alternative hypothesis (Ha) states that the population mean completion time is less than 75 minutes.

The sample mean of 69 minutes and the standard deviation of 12 minutes can be used to calculate the t-test statistic.

By comparing the calculated t-value with the critical t-value at a significance level of 0.10 and degrees of freedom of 17 (n-1), if the calculated t-value is less than the critical t-value, the null hypothesis can be rejected, concluding that the population mean completion time using the new process is less than 75 minutes.

As you're applying force to the car, the mud which is a sinking surface would but you in the same place as the car is. The car is stuck in the mud and sunk to point where it cannot be pulled out unless an outside force interferes. When you apply force into the car and try to push it out, you would be put in the same situation. You would be experiencing friction which is an opposing force, in this problem, a simple machine such as a pulley would be helpful as it can lift the car from the outside. The car would act as a load and someone or some type of machine can use force to pick the car out of the mud. But if you were to try to push it out of the mud, you would just sink as the force applied would only put you in the same situation as the car, overall resulting in both beings (objects - car, human - "you" POV) being stuck in the same conumdrum.

a) To find the mass of the 2D plate, we need to calculate its area first. The shape bounded by the lines y = 1.3x and x = 0 to 1.9 forms a right triangle.

The base of the triangle is 1.9 units, and the height is given by y = 1.3x. Integrating y with respect to x over the given range, we find the area of the triangle to be 2.775 units².

Multiplying the area by the uniform density of 2.7 kg/m², we obtain the mass of the 2D plate as 8.775 kg.

To calculate the moment of the 2D plate about the y-axis, we need to integrate x times the density over the area of the plate.

Integrating x * (1.3x) with respect to x over the given range, we find the moment to be 3.947 kg·m.

The x-coordinate of the centre of mass of the 2D plate can be determined using the formula for the centre of mass of a two-dimensional system: x = moment / mass. Substituting the values, we find the x-coordinate to be 0.993 m.

b) To find the mass of the 3D body, we need to calculate its volume first. By rotating the lines y = 1.3x and x = 0 to 1.9 about the x-axis, we obtain a solid with a known volume. Using the formula for the volume of a solid of revolution,

we can calculate the volume of this solid as 18.869 m³. Multiplying the volume by the uniform density of 3.1 kg/m³, we obtain the mass of the 3D body as 59.217 kg.

Change in momentum = mass × change in velocity

Or:

Δp = mΔv = m(vf - vi)

Plug in the given values. We can assign east to be positive and west to be negative in this instance (Velocity is a vector with direction).

Thus:

Δp = (1)(-21 - 10) = -31 kgm/s OR 31 kgm/s WEST.

The correct answer is B.

Change in momentum is EQUIVALENT to the quantity of IMPULSE.

The correct answer is H.

The true azimuth of the AB alignment is 91º 52' (east of north), the magnetic azimuth is 100º 22' (east of north), and the grid azimuth is 108º 52' (east of north).

To find the true azimuth, magnetic azimuth, and grid azimuth of the AB alignment, we need to consider the magnetic declination. The magnetic declination indicates the angle between true north and magnetic north at a specific location. In this case, the magnetic declination is 8º 30' E, which means that the magnetic north is 8º 30' east of the true north.

To calculate the true azimuth, we subtract the magnetic declination from the grid azimuth. The grid azimuth is given as 100º 22', so subtracting the magnetic declination of 8º 30' E gives us a true azimuth of 91º 52' (east of north).

The magnetic azimuth remains the same as the grid azimuth, which is 100º 22' (east of north).

The grid azimuth is calculated by adding the magnetic declination to the true azimuth. Since the magnetic declination is east, we add it to the true azimuth. Adding 8º 30' E to the true azimuth of 91º 52' gives us a grid azimuth of 108º 52' (east of north).

Explanation:

It is more likely that the truck driver was not paying attention and did not begin braking until it was too late. Therefore, the truck driver is at fault.

In order to assess the claims of the two drivers and provide expert witness testimony, we need to determine the coefficient of kinetic friction between the tires and the road for both the car and truck, as well as the speeds of each vehicle just before and after the collision. Additionally, the pre-crash angle between the velocities of the truck and car, as indicated by the provided specifications and measurements, must be taken into consideration.

The coefficient of kinetic friction between the tires and the road for the car is given by:μcar = Ff,car / Ncarwhere Ff,car is the frictional force exerted on the car by the road, and Ncar is the normal force exerted by the road on the car.Since the car is moving at a constant velocity, the frictional force exerted on the car is equal to the force required to drag the car tire across the pavement, which is 100 N. Thus,

μcar = Ff,car / Ncar = 100 / 130 = 0.7692

For the truck, the effective coefficient of friction for truck tires is only 70% that of car tires. Thus,μtruck = 0.7 * μcar = 0.7 * 0.7692 = 0.5384The speed of each vehicle just after the collision is determined using the equation:v² = u² + 2aswhere v is the final velocity, u is the initial velocity, a is the acceleration, and s is the distance traveled. For the car,

v² = 0 + 2 * μcar * g * d = 2 * 0.7692 * 9.81 * 8.2 = 126.09v = √(126.09) = 11.22 m/sFor the truck,v² = 0 + 2 * μtruck * g * d = 2 * 0.5384 * 9.81 * 11 = 118.84v = √(118.84) = 10.90 m/s

The speed of each vehicle just before the collision is determined using the conservation of momentum and the given information that the pre-crash angle between the velocities of the truck and car was 90 degrees. Let m1 be the mass of the car, m2 be the mass of the truck, u1 be the initial velocity of the car, u2 be the initial velocity of the truck, v1 be the final velocity of the car, and v2 be the final velocity of the truck.

Then, m1u1 + m2u2 = m1v1 + m2v2 (1) and, m1v1² + m2v2² = m1u1² + m2u2² (2)The angle between the velocities is 90 degrees, so their dot product is zero. Thus, u1u2 + v1v2 = 0 (3)

Solving for u1 and u2 in terms of v1 and v2 using equations (1) and (3) yields:u1 = (m1v1 + m2v2) / m1u2 = -m1v2 / m2Substituting these into equation (2) and simplifying yields:

v1² = [2m2 / (m1 + m2)] (u2² + 2gdsinθ) where θ is the angle that the truck skidded and is given by:θ = tan-1(8.2 / 27) = 17.20 degreesSubstituting the given values into this equation yields:v1² = [2 * 69700 / (13600 + 69700)] (6.7² + 2 * 9.81 * 13 * sin(17.20)) = 593.23v1 = √(593.23) = 24.35 m/s

Similarly, solving for v2 using equation (3) yields:v2 = -u1 * m2 / m1 = (13600 / 69700) * 24.35 = 4.73 m/sThus, the car was traveling at 24.35 m/s just before the collision, and the truck was traveling at 4.73 m/s just before the collision.The car driver claims to have made a full stop at the light before entering the intersection. However, the distance from the traffic light to the collision point was measured to be 13.0 m, and the maximum acceleration of the car is given as 3.0 m/s². Using the equation:s = ut + (1/2)at²

where s is the distance traveled, u is the initial velocity, t is the time, and a is the acceleration, the time it would take for the car to accelerate from rest to the speed it was traveling just before the collision is:t = √(2s / a) = √(2 * 13 / 3) = 2.27 s

This means that the car could not have been stopped at the traffic light for the duration claimed by the driver.

Thus, the truck driver's claim that the car ran the flashing red light is more credible.The truck driver claims to have begun braking in anticipation of a collision and was traveling at only 6.7 m/s at the moment of impact. The speed of the car just before the collision was determined to be 24.35 m/s.

The fact that the truck skidded further than the car indicates that the truck driver was traveling at a higher speed. Furthermore, the truck driver was traveling at a speed of 6.7 m/s at the moment of impact, which is higher than the speed at which the car would have been traveling if it had been stopped at the traffic light (4.58 m/s).

Thus, it is more likely that the truck driver was not paying attention and did not begin braking until it was too late. Therefore, the truck driver is at fault.

Explanation:

A simple pendulum consists of a mass (usually represented as a small object or bob) attached to a string or rod of negligible mass. The mass is free to swing back and forth under the influence of gravity.

In the figure, the point of suspension is denoted by "O," and the mass (bob) is represented by the small circle. The string or rod is represented by the vertical line connecting the point of suspension to the bob.

Amplitude:

The amplitude of a pendulum refers to the maximum displacement or swing of the bob from its equilibrium position. In the figure, the amplitude can be represented by the angle formed between the vertical position and the position of the bob when it swings to its maximum distance on one side. It is usually denoted by the symbol "A."

Effective Length:

The effective length of a pendulum refers to the distance from the point of suspension to the center of mass of the bob. It represents the distance over which the mass swings back and forth. In the figure, the effective length can be measured as the length of the string or rod from the point of suspension to the center of the bob. It is usually denoted by the symbol "L."

It is important to note that the amplitude and effective length of a simple pendulum affect its period of oscillation (the time taken for one complete swing). The relationship between these parameters and the period can be described by mathematical formulas.

Overall, the simple pendulum is a fundamental concept in physics and provides a simplified model for understanding oscillatory motion and the principles of periodic motion.

Hi There, Buddy!

To solve this problem, let us divide the entire motion into 2 phases

1.) When the elevator is moving with an acceleration

2.) When the elevator has a deceleration

For the first half -

u = 0 , a = 0.6 , t = t1

v = 0.6(t1)  ---------- ( 1 )

s = 1/2 x 0.6 x (t1)^2 = 0.3(t1^2) -------- ( 2 )

For the second half -

u = 0.6(t1) , a = -0.8 , v = 0

0.6 x (t1) = 0.8 (t2) ----> 3(t1) = 4(t2) ---------- ( 3 )

0.36(t1)^2 = 1.6 s2 ---------- ( 4 )

Now, we know that the total time taken is 10 seconds

------- t1 + t2 =10 , 3t1 = 4t2 ---- t1 = 40/7 , t2 = 30/7

Now, substitute values of t1 and t2 in s1 and s2 and add both s1 and s2 to get total distance travelled.
