To draw the resultant vector, join the tail of the first vector with the second vector's head and put the arrowhead. To determine the magnitude, measure the length of resultant R, and to find out the direction, measure the angle of the resultant with the x-axis.

the magnitude of the average force required to stop the sled is 16 times the velocity of the sled in meters per second.

To calculate the magnitude of the average force required to stop the sled, we can use the concept of impulse and momentum. The equation that relates these two concepts is:

FΔt = mΔvwhere F is the force, Δt is the time interval during which the force is applied, m is the mass of the object, and Δv is the change in velocity.Let's assume that the sled was initially moving with a certain velocity v and that you want to bring it to a complete stop.

The final velocity of the sled will be 0 m/s. Since the mass of the child and sled is 32 kg, we can use the following equation to calculate the average force required to stop the sled:

FΔt = mΔvF Δt = (32 kg) (- v)F Δt = -32v

To determine the value of F, we need to know the time interval Δt during which the force is applied. If we assume that it takes 2 seconds to bring the sled to a stop, then:

F (2 s) = -32vF = -16v Newtons

Therefore, the magnitude of the average force required to stop the sled is 16 times the velocity of the sled in meters per second.

Answer:

Relative density is proportional to the frequency of a material's density to its water density. Because both have had the same proportions, their proportion is also dimensionless.

Explanation:

The dimension of relative density:-

Relative Density of a Substance (R.D.) = Substance Density / Water Density.

Therefore, R.D. Is just a ratio or a number. There are no units or dimensions to it.

For example:- The density of iron is 8.5 GM's/cm^3 & the density of water is 1 gm/cm^3 (in cgs units).

Tension:-   Surface tension is the propensity of the new worlds and infographics to reduce to the particle size which is least appropriate. Atmospheric pressure helps insects (e.g. water striders) can travel or move and on a water surface, typically object is sensed rather than water.

Answer:

Water gains energy during evaporation and releases it during condensation in the atmosphere

Explanation:

In the water cycle, heat energy is gained or lost by water as it undergoes various processes in the cycle.

In evaporation, water molecules gains energy because the molecules of water vibrate faster and become more energetic. Hence they are able to escape into the atmosphere from the surface of the liquid.

In condensation, the molecules of gaseous water looses energy and becomes liquid.

Hence, water gains energy during evaporation and releases it during condensation in the atmosphere.

Explanation:

Based on the given information, the temperature at your station in Houston is likely to decrease in the next 2 hours due to the constant temperature advection and is estimated to be 63.04ºF (16.8ºC).

Given the wind speed of 10 m/s from the west-northwest, we can use the concept of wind advection to adjust the temperature gradient based on the speed and direction of the wind.

First, we need to convert the wind speed from meters per second to kilometers per hour, as the temperature gradient is typically expressed in degrees per kilometer.

10 m/s is equivalent to 36 kilometers per hour (10 m/s * 3.6 km/h).

Next, we can adjust the temperature gradient based on the wind speed. The temperature change due to advection is typically estimated using a rule of thumb, which suggests that for each 10 kilometers per hour of wind speed, the temperature change is approximately 1 degree Celsius (or 1.8 degrees Fahrenheit) over a distance of 100 kilometers.

In this case, with a wind speed of 36 kilometers per hour, the adjusted temperature change due to advection would be approximately 3.6 degrees Celsius (or 6.48 degrees Fahrenheit) over a distance of 100 kilometers.

Now, let's calculate the temperature change at your station in Houston after 2 hours using the adjusted temperature gradient.

Temperature change = Adjusted temperature gradient × Distance × Time

Temperature change = 3.6°C/200 km * 200 km * 2 hours

Calculating the result, the temperature at your station in Houston is estimated to decrease by 7.2 degrees Celsius (or 12.96 degrees Fahrenheit) after 2 hours.

To find the final temperature at your station, subtract this temperature change from the initial temperature of 76ºF (24ºC):

Final temperature = Initial temperature - Temperature change

Final temperature = 76ºF (24ºC) - 12.96ºF (7.2ºC)

The estimated final temperature at your station in Houston after 2 hours is approximately 63.04ºF (16.8ºC).

The expression for the energy stored (E) in a stretched wire of original length (L), cross-sectional area (A), tension (T), and Young's modulus (Y) is given by E = Y * e * ln(L) * A

The work done to stretch the wire can be calculated by integrating the force applied over the displacement. In this case, the force applied is the tension (T) in the wire, and the displacement is the change in length (ΔL) from the original length (L) to the stretched length (L + ΔL).

The tension in the wire is given by Hooke's law, which states that the tension is proportional to the extension of the wire:

T = Y * (ΔL / L)

where Y is the Young's modulus of the material of the wire.

Now, let's calculate the work done to stretch the wire:

dW = T * dL

Integrating this expression from L to L + ΔL:

W = ∫ T * dL = ∫ Y * (ΔL / L) * dL

W = Y * ΔL * ∫ (dL / L)

W = Y * ΔL * ln(L) + C

Here, C is the constant of integration. Since the energy stored in the wire is zero when it is unstretched (ΔL = 0), we can set C = 0.

Finally, the expression for the energy stored in the wire (E) is:

E = W = Y * ΔL * ln(L)

or, if we substitute the cross-sectional area (A) and strain (e) of the wire, where e = ΔL / L:

E = Y * e * ln(L) * A

Thus, the expression for the energy stored (E) in a stretched wire of original length (L), cross-sectional area (A), tension (T), and Young's modulus (Y) is given by:

E = Y * e * ln(L) * A

The distance the springs need to bring the car to a stop can be calculated using the equation for the potential energy of an object at a height, which is:

PE = mgh

where m is the mass of the object, g is the acceleration due to gravity (9.8 m/s^2), and h is the height.

In this case, the car has a mass of 1,836 kg and is at a height of 88.6 meters. So the potential energy of the car at the top of the roller coaster is:

PE = 1,836 kg * 9.8 m/s^2 * 88.6 m = 1.5*10^5 J

Next, we need to find the work done by the spring. Work can be calculated using the equation

W = 1/2 * kx^2

where k is the spring constant (100,000 N/m) and x is the compression distance of the spring.

Since the work done by the spring is equal to the potential energy of the car, we can set the two equations equal to each other and solve for x (the compression distance of the spring):

1/2 * kx^2 = 1.510^5 J

x = sqrt(2 * 1.510^5 J / 100,000 N/m)

x = sqrt(30000/100000)

x = 0.173 m

Therefore, the spring needs a distance of 0.173 m to bring the car to a stop.

(a) The initial temperature is 373.95 K.

(b) The final temperature is 546.15 K.

(c) The total internal energy change of the fluid during this process is 515.4 kJ.

(d) The process can be represented as an isochoric heating process on the P-v diagram and as an isobaric expansion process on the T-v diagram.

(a) To find the initial temperature, we can use the saturated steam tables. At a pressure of 200 kPa, the corresponding saturation temperature is 373.95 K.

(b) Since the volume doubles, the process is an isochoric (constant volume) heating process. Using the ideal gas law, we can determine the final temperature. The initial and final volumes are related by the equation V_final = 2V_initial. Since the mass remains constant, the specific volume (v) is inversely proportional to the density (ρ). Therefore, ρ_final = ρ_initial/2. Using the ideal gas law, we can calculate the final temperature to be 546.15 K.

(c) The total internal energy change can be calculated using the equation ΔU = mC_vΔT, where m is the mass of the fluid and C_v is the specific heat at constant volume. Given the mass as 0.5 kg, the specific heat of water at constant volume, and the temperature change, we can find that the total internal energy change is 515.4 kJ.

(d) On the P-v diagram, the process is represented as a vertical line at 200 kPa, indicating constant pressure. On the T-v diagram, the process is shown as an upward-sloping line, indicating an isobaric expansion process. The initial state is represented as a point on the left, and the final state is represented as a point on the right.
