Answer:

When you know both the speed and direction of an object's motion, you know the velocity of the object.

Newton's law of cooling states that the rate of change of the temperature of an object is proportional to the difference between its own temperature and the temperature of its surroundings. This relationship can be mathematically modeled using a first-order ordinary differential equation.

The general form of the equation for Newton's law of cooling is:

[tex]dT/dt = k(T_s - T)[/tex]

where T is the temperature of the object, [tex]T_s[/tex] is the temperature of its surroundings, k is the constant of proportionality known as the cooling rate, and t is time.

To solve this differential equation, we need to find the function T(t) that satisfies the equation. One method to solve this equation is to use the method of separation of variables. We separate the variables T and t, integrate both sides, and then solve for T.

The solution to this differential equation gives us the time-dependent temperature of the object as it cools down to the temperature of its surroundings. This solution is useful in understanding the cooling process of objects in various real-world scenarios such as heat transfer in electronics, refrigeration, and air conditioning systems.

Explanation:

The overall displacement can be found using the Pythagorean theorem, which states that in a right triangle, the square of the hypotenuse (the overall displacement) is equal to the sum of the squares of the other two sides.

Let's call the displacement in the northwest direction "x" and the displacement in the east direction "y". The overall displacement can be found using the equation:

√(x^2 + y^2) = √((-10)^2 + (40)^2 + (-60)^2) = √(1600 + 1600 + 3600) = √(7000) = 84.85 km

So the overall displacement of the car from the starting point is approximately 84.85 km.

Increase in small-artery pressure would increase capillary hydrostatic pressure most.

What are oncotic pressure and capillary hydrostatic pressure?

The systemic perfusion of the capillary, the arterial and venous pressures, and the variation in capillary resistance all affect the hydrostatic pressure. Oncotic pressure results from the inability of plasma proteins to easily pass the capillary membrane, particularly albumin.

Because of the hydrostatic pressure, fluid leaks through the capillary's pores and into the interstitial space as the blood travels along it. As the blood flows down the capillary from the arterial to the venous end, the pressure exerted by the blood will decrease.

The resultant speed of the plane would be 230.03 km/hour

Vectors are the units that have both magnitude and direction. We can directly add and subtract if they are going in the same or the opposite direction. If they are all going in the same direction, we employ the formula that will take the square root of each vector's sum of squares. In this case, the vectors are inclined to one another with angle 45° (plane flying from east to northeastern)

The formula below is used to calculate the resultant vector from two vectors that are inclined to one another. The resultant vector, R, is created when the vectors A and B are inclined at an angle Ø to one another:

                                  R² = A² + B² + 2ABCosØ

Thus, the resultant speed of the plane would be

Using algebraic expressions, the constant acceleration is represented as 2(d/4)/t^2 and the ratio of the the average velocity is 8/t

A. To meet the puck one quarter of the distance from where you started, you need to cover one quarter of the total distance that the puck travels.

Let's call the initial distance between you and the puck "d". Then, the total distance the puck travels is d, and the distance you need to cover is d/4.

The time it takes for the puck to travel d is d/8 (since the puck's velocity is 8 m/s). The time it takes for you to cover d/4 is t.

Using the equation of motion, we can find the acceleration needed:

d = (1/2)at^2

d/4 = (1/2)(a)t^2

(1/2)(a)t^2 = d/4

a = 2(d/4)/t^2

We don't know the value of "d", so we cannot calculate the exact value of "a". But we can find it in terms of "t".

B. To calculate the ratio of your average velocity to the puck's constant velocity, we can use the equation:

v(average) = d/t

Let's call your average velocity "v". Then,

v/8 = d/(4t)

v/8 = d/4 * 1/t

v/8 = v(average)/t

v/8 = v(average)/t

v/v(average) = 8/t

Answer:

Explanation:

Given that the metal chloride formula is MC13, we can assume that the metal (M) is represented by the atomic symbol "M" and the atomic weight of chlorine (Cl) is 35.5.

Since 20% of the total weight of the compound is the metal, the atomic weight of the metal (M) can be calculated as:

M = (0.2 * (13 * 35.5 + M)) / 13 = 0.2 * 35.5 + 0.2 * M

Solving for M:

0.2 * M = (0.2 * 35.5) / (1 - 0.2) = 7.1

M = 7.1 / 0.2 = 35.5

So the atomic weight of the metal (M) is 35.5, and the answer is (b) 56.

Answer: approximately 13.6 m/s.

Explanation: The sled's speed after it has traveled the first 100 m can be determined using the principles of kinematics.  We can use the equations of motion to solve this problem.

First, let's identify the given information:

- Initial speed (v₀) = 9.2 m/s (sled's top speed before starting down the track)

- Distance traveled (s) = 100 m (the first 100 m of the track)

- Angle of the slope (θ) = 9.0° (angle of the track)

To find the sled's speed after traveling 100 m, we need to determine the final speed (v) using the equation of motion that relates initial speed, final speed, distance, and angle:

v² = v₀² + 2as

Here's how we can calculate it step by step:

Convert the angle from degrees to radians:

θ = 9.0° = (9.0° * π) / 180 ≈ 0.157 radians

Determine the acceleration (a) using the gravitational acceleration and the angle of the slope:

a = g * sin(θ)

g ≈ 9.8 m/s² (acceleration due to gravity)

a ≈ 9.8 m/s² * sin(0.157) ≈ 1.36 m/s²

Substitute the known values into the equation of motion:

v² = (9.2 m/s)² + 2 * (1.36 m/s²) * (100 m)

Simplify and solve for v:

v ≈ √(9.2² + 2 * 1.36 * 100) ≈ 13.6 m/s

Therefore, the sled's speed after traveling the first 100 m is approximately 13.6 m/s.

Explanation:

0.00455 moles of air must be released from the tire to restore the pressure to 210 kPa at 50 degrees C.

The pressure rise in a 0k tire when the air temperature rises from 25 degrees C to 50 degrees C can be calculated using the ideal gas law. The formula is

PV = nRT

where P is the pressure, V is the volume, n is the number of moles of gas, R is the ideal gas constant, and T is the temperature. In this case, the temperature is rising from 25 degrees C to 50 degrees C, so the pressure will increase with the temperature.

By plugging these values into the equation, we can calculate that the pressure increase is 45.5 kPa.

To restore the pressure to its original value of 210 kPa at 50 degrees C, we need to bleed off the amount of air equal to the pressure increase. This is equal to 45.5 kPa, or 0.00455 moles. This means that 0.00455 moles of air must be released from the tire to restore the pressure to 210 kPa at 50 degrees C.

According to Coulomb's law of force, the electrostatic force between two charges separated by a distance of r is given as follows:

Fc = Ke q1 q2 /r²

where Ke = 8.9 × 10⁹ Nm²/C²

Given the charge of  q1 = 3.97  × 10⁻⁹ C

charge of q3  = -5.95 × 10⁻⁹ C

distance r = 0.200 m

then Fc =  8.9 × 10⁹ Nm²/C²  ( 3.97  × 10⁻⁹ C) (-5.95 × 10⁻⁹ C)/(0.200 m)² = -5.25 × 10⁻⁶ N

Similarly, the force on q3  by the charge q2 is calculated as follows:

distance to q2 = 0.30 m

charge of q2 = 4.99 × 10⁻⁹ C.

Then Fc =   8.9 × 10⁹ Nm²/C²  (4.99 × 10⁻⁹ C ) (-5.95× 10⁻⁹ C)/(0.30 m)² = - -2.93 × 10⁻⁶ N

The net electric force acting on A =  3.9 × 10⁻⁵ N - (-1.9 × 10⁻⁵ N) = 5.8 × 10⁻⁵ N.

avg speed= distance/time

v = 5100m/60s

v = 85m /s

so the plane was traveling a average distance of 85m per second.
