Explanation:

The frictional force experienced on the coin, when it is at a distance of 14 cm is 0.77N and the coefficient of static friction when the coin slides off will be 0.964.

To find the answer, we need to know more about the friction.

                    \(m=140*10^{-3} kg\\w=1 rev/s=2\pi rad/s\\r_1=14*10^{-2}m\\g=9.81m/s^2\\\)

                    \(f=F_c=ma_c=m*r_1w^2\\f=140*10^{-3}*14*10^{-2}*4*\pi ^2=0.77N\)

                              \(f_s=kN,\\\\Where, \\N=mg\\\\k=\frac{f_s}{mg}\)

                         \(F_c=f_s=mrw^2=140*10^{-3}*24*10^{-2}*4\pi ^2\\f_s=1.325N\)

                   \(k=\frac{1.325}{140*10^{-3}*9.81}=0.964\)

Thus, we can conclude that, the frictional force experienced on the coin, when it is at a distance of 14 cm is 0.77N and the coefficient of static friction when the coin slides off will be 0.964.

Answer:

If it is a true mixture, the mixing enthalpy is negligible, and there is no reaction or phase change, then you can do this using exclusively the temperatures of the individual compounds and their heat capacities. Any other process that takes place needs to be taken into account separately.

The solution can be found by understanding that we’re only using state variables. You can design any complicated process that starts with the starting situation and ends up at the ending situation, and the state variables will be the same. And sometimes a complicated process is easier to calculate than the simple one-step process, like here when mixing multiple components.

One way that will work is to start by bringing all compounds to the lowest temperature of either of the compounds. All but one of the compounds must be cooled down for this; make sure to calculate for each of the components how much energy is released. Now, mix all the components together. In the simplest situation sketched above you can calculate the heat capacity of the mixture by adding all the heat capacities of the components. Use this total heat capacity to calculate how much you can heat up the mixture using the energy you saved in cooling down the components earlier. This will be your desired end situation.

In case there are any phase changes or other processes in between, you need to take the energy needed for those into account too but in very similar ways.

My people originally used the sha'ah, yom, and khelek for time, the amah for length, the tchum shabbat for distance, and the epha, omer, baytsa, log, and kazayit for volume.

See what I mean ?

Given parameters:

Distance to hardware shop = 5 miles

Time to reach hardware shop = 10 minutes

Time spent at the shop = 30 minutes

Average speed to customer home = 45 mph

Time taken for the travel = 20 minutes

Unknown:

Average speed of the contractor = ?

Solution:

 Average speed is the total distance covered divided by the total time taken.

   Average speed = \(\frac{total distance}{total time taken}\)  

     total distance = distance to hardware shop + distance to customer's home

We do not know the distance to customer's home but we have been given the speed and time, so we can find the distance.

  Distance  = speed x time

 Convert the time to hrs and solve;  

                       60 minutes  = 1 hr

                       20 minutes  = \(\frac{20}{60} hr\)  = \(\frac{1}{3} hr\)

So, Distance  = 45mph x \(\frac{1}{3} hr\)   = 15miles

Now;

   Total distance  = 5 + 15 = 20miles

Total time = time to reach hardware shop + time to reach customer's house

                  = 10 + 20

                  = 30 minutes

Convert the time from minutes to hrs;

                 60 minutes  = 1hr

                 30 minutes  = \(\frac{30}{60}\)   = 0.5hr

So;

    Average speed  = \(\frac{20}{0.5}\) = 40mph

The average speed is 40mph

The person must have a velocity of -2.5 kg m/s ÷ 35 kg = -0.0714 m/s.

Velocity is a vector quantity that describes the rate and direction of an object's motion. It is the magnitude of the speed of an object, measured in meters per second (m/s). Velocity can also be used to describe the rate of change of an object's position over time. It is an important concept in physics and engineering, as it is used to measure the acceleration and deceleration of objects.

Since the person has a mass of 35 kg and the snowball has a mass of 0.5 kg, and they both have the same velocity of 5 m/s,
the total momentum of the system must remain constant.
Therefore, since the snowball has a momentum of 0.5 kg * 5 m/s
= 2.5 kg m/s, the person must have a momentum of -2.5 kg m/s.
This means that the person must have a velocity of -2.5 kg m/s ÷ 35 kg = -0.0714 m/s.

The primary goal of laundering healthcare linens is to remove soil and microbial contamination to prevent the spread of infections. The temperature of the wash water is a critical factor in achieving this goal because it directly affects the effectiveness of the cleaning and disinfection process.

According to the CDC guidelines, the minimum wash water temperature for processing healthcare linens is 160 to 165 degrees Fahrenheit (71 to 74 degrees Celsius). This temperature range is based on the fact that most bacterial pathogens and viruses are killed at temperatures above 160 degrees Fahrenheit.

It is important to note that different types of healthcare linens may have different temperature requirements based on their fabric type and level of contamination. For example, some delicate fabrics may require lower temperatures to prevent damage, while heavily soiled linens may require higher temperatures to ensure effective cleaning.

In addition to temperature, other factors such as the duration of the wash cycle, detergent selection, and mechanical action are also important in achieving effective cleaning and disinfection of healthcare linens. Proper training and adherence to established laundry protocols are essential to ensure that healthcare linens are processed safely and effectively.

The pendulum bob B of mass M is released from rest when \(\theta=0^0\). the tension in the cord at the instant the bob reaches point D, \(\theta = \theta1 = 45^0\) is 41.72 N.

The motion of a simple pendulum is idealized. It consists of a point mass attached to an inextensible, massless cable or rod suspended from a pivot point. The pendulum oscillates about the pivot point in a plane that is orthogonal to the rod or cable and has a period that depends solely on the pendulum's length and gravitational acceleration.

As a result, the time period of a pendulum is calculated. The time it takes for a pendulum to swing back and forth is referred to as the time period. It is denoted by T and measured in seconds.

A simple pendulum's time period is calculated using the formula:

\(T = 2\pi(L/g)^{(1/2)}\)

where T = time period, L = length of the pendulum, and g = acceleration due to gravity = \(9.81 m/s^2\).

Tension in the string at the time of release \(\theta = 0^0\)in the pendulum. It implies that the pendulum is vertical. At this point, the tension in the cable is equal to the weight of the bob.

Mg = Tension = 3 x 9.81 = 29.43 N

When the bob reaches point D, \(\theta = \theta1 = 45^0\), the tension in the cord is determined. At point D, the velocity of the bob is

\(v = L\sqrt2gL = \sqrt(2 * 9.81 * 2) = 6.26 m/s\)

Kinetic Energy of bob KE = \((1/2)mv^2KE = (1/2) * 3 * (6.26)^2 = 58.46 J\)

Potential energy of the bob at D = mghU = mghU = 3 × 9.81 × (2 - 2cos45) = 39.22 J

Total mechanical energy at D = KE + U58.46 + 39.22 = 97.68 J

The total mechanical energy at D is equal to the initial mechanical energy since no energy is lost in the absence of any external forces.

WE = KE + UE = PE = mgh = 3 x 9.81 x 2 = 58.86 J

From the formula of total mechanical energy,

WE = Tension x L cosθTension

= (WE / L cosθ)Tension = (58.86 / (2cos45))

= 41.72 N

Therefore, the tension in the cord at the instant the bob reaches point D, \(\theta = \theta1 = 45^0\) is 41.72 N.

It's a little unclear what you mean by "the top half" and "the bottom half" of the Vernier caliper.

However, assuming you are referring to the main scale and the Vernier scale, respectively, here is how you can read the caliper:

Read the main scale: Look at the scale on the top half of the caliper and identify the whole number before the decimal point. In this case, it should be 13 (i.e., one inch plus three tenths of an inch).

Read the Vernier scale: Look at the scale on the bottom half of the caliper and find the line that lines up with a line on the main scale. The number corresponding to this line on the Vernier scale is the fraction of an inch you need to add to the main scale reading. In this case, it seems like the Vernier scale has 10 divisions that span the same distance as 9 divisions on the main scale, which gives a Vernier constant of 0.1 inch / 9 = 0.011111 inch. Assuming the zero line on the Vernier scale lines up with a line on the main scale, the line on the Vernier scale that lines up with another line on the main scale should be the one that is 0.1 inch minus 0.3 inch = -0.2 inch away from the zero line. However, since the Vernier constant is 0.011111 inch, this line should be the 18th line on the Vernier scale (counting from the left). Therefore, the fraction of an inch to add to the main scale reading is 0.018 inch (i.e., 18 divisions times the Vernier constant).

Putting these together, the reading on the Vernier caliper should be 13.018 inches.

Let lift force F be created by propellers at angle of Ф with the horizontal .

The vertical component of this force will balance the weight of helicopter and horizontal component will balance the air resistance .

F sinФ = mg = 2750 x 9.8 = 26950 N

F cosФ = 7510 N

Squaring and adding ,

F² = 26950² + 7510²

F = 27976.82 N .

The spring has an unstretched length of 1.855m and is calculated from the spring constant k=1.60 N/m.

The bounce frequency of the pendulum, f = 1/2π √(k/m) where k is force constant and m is the mass of an apple.

From the given,

mass of an apple = 1 N = 1/9.8 = 0.102 kg

force constant k = 1.6 N/m

frequency f₁ = 1/2π √(1.6/0.102 kg)

                 = 0.630 Hz

The bounce frequency of the pendulum = 0.630 Hz.

The frequency of the swing pendulum, f₂ = 1/2π (√g/l) where g is the acceleration due to gravity and l is the length of the pendulum.

The swing frequency is half of the bounce frequency, f₂ = 1/2 (0.630)

f₂ = 0.315 Hz.

f₂ = 1/2π (√g/l)

0.315 = 1/2π (√9.8 / l)

length l = 2.48m

Extension of length = weight of an apple/force constant

Extension of length = (1N)/(1.6) = 0.625 m

The unstretched length = length- an extension of length

                                         = 2.48 - 0.625
