When can acceleration be observed and what result will it have on an object?

The required volume of the gas is 0.52 L.

Diminishing the volume of a contained gas will expand its tension, and expanding its volume will diminish its strain. As a matter of fact, on the off chance that the volume increments by a specific variable, the tension declines by a similar element, as well as the other way around.

V1 = 1.56 L, P1 = 1 atm, P2 = 3 atm,

To find: V2 of gas

So, P1V1 = P2V2

V2 = P1V1/P2

V2 = 1.56(1)/3 = 0.52 L

Thus, required volume of gas is 0.52L

Based on the given information, we need to determine the proportion of strain gauges that meet the specification of having a resistance within the range of 100 ± 0.7 ohms.

To find the proportion of acceptable strain gauges, we need to calculate the area under the normal distribution curve within the specified range.

First, we standardize the range by subtracting the mean and dividing by the standard deviation: (0.7 - 100) / 0.3 = -0.333. This gives us a standardized value of -0.333.

Next, we consult a standard normal distribution table or use statistical software to find the proportion of the area under the curve to the left of -0.333. Looking up this value in the table, we find that it is approximately 0.3707.

Since the normal distribution is symmetric, we multiply this proportion by 2 to account for the area to the right of the range as well. Therefore, the proportion of gauges that meet the specification is approximately 0.7414 or 74.14%.

In conclusion, approximately 74.14% of the strain gauges will have a resistance within the specified range of 100 ± 0.7 ohms, based on the given mean and standard deviation of the resistance values.

If a penny is dropped from a building that is 95 m tall then it would 3.111 seconds take the penny to hit the ground below

There are three equations of motion given by  Newton

The first equation is given as follows

v = u + at

the second equation is given as follows

S = ut + 1/2×a×t²

the third equation is given as follows

v² - u² = 2×a×s

Keep in mind that these calculations only apply to uniform acceleration.

As given in the problem, A penny is dropped from a building that is 95 m tall,the initial velocity of the penny is zero, the acceleration acting is due to the acceleration due to gravity

height of the building (S) = 95 meters

initial velocity(u) = 0 m/s

acceleration(a) = 9.81 m/s²

By using the second equation of motion given by newton

S = ut + 1/2at²

S = 95 m ,u= 0 m/s , a= 9.81 m/s² and t =? seconds

95 = 0 + 9.81t²

t² = 95/9.81

t = 3.111 seconds

C) is the correct answer

Explanation:

Find an energy is E =mgh, so E = 45*10*19=8550j

The correct order of increasing impedance is:

C. PZT, gel, skin, matching layer

Impedance is a measure of the opposition to the flow of sound waves in a medium. It depends on the density and speed of sound in the material. In the given options, the order of increasing impedance can be determined by considering the properties of the materials involved.

PZT (lead zirconate titanate) has a higher impedance than gel, skin, and the matching layer. PZT is a piezoelectric material commonly used in ultrasound transducers and has a higher density and speed of sound, leading to higher impedance.

Gel has a lower impedance compared to PZT but higher impedance than skin and the matching layer. Gel is used as a coupling medium between the transducer and the skin to enhance acoustic coupling and minimize impedance mismatch.

Skin has a lower impedance than both gel and the matching layer. It is the outermost layer and acts as an interface between the transducer and the biological tissue.

The matching layer has the lowest impedance among the given options. It is designed to match the impedance of the PZT to the impedance of the tissue being imaged, facilitating efficient sound transmission.

Therefore, the correct order is C.

In this scenario, the 1000-kg car and 2000-kg truck are colliding and the resulting wreckage has a combined mass of 3000 kg, the velocity of the wreckage just after impact is 11.67 m/s.  

The combined velocity of the two vehicles after the collision can be calculated by applying the law of conservation of momentum.

The law of conservation of momentum states that the momentum of a system remains constant if there are no external forces acting upon it.

Momentum (p) is equal to the mass (m) multiplied by velocity (v), so p = mv.

The momentum of the 1000-kg car traveling north at 15 m/s is 15000 kg m/s, and the momentum of the 2000-kg truck traveling east at 10 m/s is 20000 kg m/s.

After the collision, the momentum of the combined wreckage is the sum of the two vehicles' momentums, or 35000 kg m/s.

As the combined mass of the wreckage is 3000 kg, the velocity of the wreckage just after impact is

35000/3000

The volume flow rate through the hose and nozzle is 0.339 l/s, the speed of the water in the nozzle is approximately 9.058 m/s.

To calculate the speed of the water in the nozzle, we can use the principle of continuity, which states that the volume flow rate is constant at any point along a pipe or hose.

The equation for the principle of continuity is given by A₁v₁ = A₂v₂, where A₁ and A₂ are the cross-sectional areas of the hose and nozzle, and v₁ and v₂ are the velocities of the water in the hose and nozzle, respectively.

First, we need to convert the given volume flow rate from liters per second to cubic meters per second, which gives us 0.339 × 10⁻³ m³/s.

Next, we can calculate the cross-sectional areas of the hose and nozzle using the given radii. The area of a circle is given by the formula A = πr².

For the hose, A₁ = π(0.01878 m)² and for the nozzle, A₂ = π(0.00595 m)².

Using the principle of continuity, we can rearrange the equation to solve for v₂: v₂ = (A₁v₁) / A₂.

Substituting the known values, we find v₂ ≈ (π(0.01878 m)² × 0.339 × 10⁻³ m³/s) / (π(0.00595 m)²).

Simplifying the equation, we get v₂ ≈ 9.058 m/s. Therefore, the speed of the water in the nozzle is approximately 9.058 m/s.

The extra cost of fuel for driving 83 mph instead of 73 mph is $3.7671.

The speed of your automobile has a huge effect on fuel consumption. Traveling at 65 miles per hour (mph) instead of 55mph can consume almost 20% more fuel. As a general rule, for every mile per hour over 55 , you lose 2% in fuel economy.

If you take a 400-mile trip and your average speed is 83mph rather than the posted speed limit of 73mph, then the extra cost of the fuel is calculated as:

* **Fuel consumption at 83 mph:** 30 mpg * (1 - 2% * (83 - 55)) = 27.6 mpg

* **Fuel consumption at 73 mph:** 30 mpg * (1 - 2% * (73 - 55)) = 29 mpg

* **Extra fuel used:** 400 miles / 27.6 mpg - 400 miles / 29 mpg = 2.4 gallons

The outer core's temperature ranges from 8,132 to 9,932 degrees Fahrenheit (4,500 degrees C and 5,500 degrees C). The most common material used to construct earthquake-resistant buildings is steel, which is necessary for developing a structure that can withstand seismic waves.

The World Steel Association claims that because ductile structures disperse seismic wave energy, they are safer. The Earth's inner core contains even more metal than the outer core.
