Answer:

Explanation:

You didn't ask a question here, but I assume you want the pressure? You can use the ideal gas equation stating that:

PV = nRT

The 'P' is pressure, the 'V' is volume, the 'n is number of moles of gas, the 'R' is the ideal gas constant, and the 'T' is the temperature. First convert the Celsius degrees into Kelvin by using the following relation:

C + 273.15 = K

4 + 273.15 = 277.15K

Now, find the volume of a cylinder by using:

\(V=\pi r^2l\)

The 'l' is the length of the cylinder

Now just plug and chug everything into the ideal gas equation:

\(PV=nRT\)

\(P(\pi r^2l)=(5moles)(8.3145J/moles*K)(277.15K)P=\frac{11.52J}{\pi r^2l}\)

The magnitude of F black-red compared to F red-black  5 times greater.

The force exerted between two charged objects is given by Coulomb's law:

F = k * (q1 * q2) / r^2

Let's denote the charge on the red balloon as q_red and the charge on the black balloon as q_black. Since the black balloon has 5 times the charge of the red balloon, we can write:

q_black = 5 * q_red

Now let's consider the force exerted by the black balloon on the red balloon. According to Coulomb's law, this force is given by:

F_black-red = k * (q_black * q_red) / r^2

Substituting q_black = 5 * q_red, we get:

F_black-red = k * (5 * q_red * q_red) / r^2

Simplifying this expression, we get:

F_black-red = 5 * (k * q_red^2) / r^2

Similarly, the force exerted by the red balloon on the black balloon is given by:

F_red-black = k * (q_red * q_black) / r^2

Substituting q_black = 5 * q_red, we get:

F_red-black = k * (q_red * 5 * q_red) / r^2

Simplifying this expression, we get:

F_red-black = 5 * (k * q_red^2) / r^2

Comparing the two expressions, we can see that:

F_black-red = 5 * F_red-black

Therefore, the magnitude of the force exerted by the black balloon on the red balloon is 5 times greater than the magnitude of the force exerted by the red balloon on the black balloon.

The explanation can be completed by performing the calculations and providing the final numerical value for the average velocity.

To find the car's average velocity between t = 3 and t = 8, we need to calculate the displacement of the car during this time interval and divide it by the total time elapsed.

The displacement of an object can be obtained by integrating its velocity function over the given time interval. In this case, the velocity function is v(t) = 3t^(1/2) + 3. To find the displacement, we integrate v(t) with respect to t:

∫[3 to 8] (3t^(1/2) + 3) dt

Integrating the first term, we get (2/3)t^(3/2), and integrating the second term, we get 3t. Evaluating the integral over the interval [3 to 8]:

[(2/3)(8^(3/2)) + 3(8)] - [(2/3)(3^(3/2)) + 3(3)]

Simplifying this expression, we find the displacement of the car over the interval [3 to 8].

Next, we calculate the average velocity by dividing the displacement by the total time elapsed, which is 8 - 3 = 5 seconds.

Finally, we obtain the average velocity of the car between t = 3 and t = 8 by dividing the displacement by the time:

Average velocity = Displacement / Time

Based on the information provided, the correct statements are:

B.) The angle between the thread supporting A and the vertical is less than the angle between the thread supporting B and the vertical.

D.) A and B exert the same magnitude forces on each other.

Explanation:

According to Coulomb's Law, the force between two charged objects is given by:

F = k(|q1||q2|) / r²

Where:

F is the force between the objects,

k is the electrostatic constant,

|q1| and |q2| are the magnitudes of the charges, and

r is the distance between the charges.

In this case, Balloon A has charge q, and Balloon B has charge 10q. Let's assume the distance between them is the same.

A.) The force that A exerts on B is 10 times the force that B exerts on A. Incorrect.

Using Coulomb's Law, the forces between A and B are proportional to the magnitudes of their charges. Therefore, the force that A exerts on B is the same as the force that B exerts on A because the magnitudes of their charges are proportional (q and 10q). The forces are equal, not ten times different.

B.) The angle between the thread supporting A and the vertical is less than the angle between the thread supporting B and the vertical. Correct.

Since Balloon B has a higher charge (10q), it will experience a greater repulsive force from Balloon A. As a result, Balloon B will be pushed away more than Balloon A, causing the thread supporting Balloon B to be at a larger angle with the vertical than the thread supporting Balloon A.

C.) The force that A exerts on B is 1/10 the force that B exerts on A. Incorrect.

As explained earlier, the forces are equal in magnitude, not 1/10 of each other.

D.) A and B exert the same magnitude forces on each other. Correct.

Since the magnitudes of their charges are proportional, the forces they exert on each other will be equal in magnitude, as given by Coulomb's Law.

The full form of rms velocity is Root mean square velocity. The temperature at which hydrogen molecules have the same rms speed as nitrogen molecules at 155 ∘C is 30.57 K.

The root mean square velocity is defined as the square root of the mean of squares of the velocity of individual gas molecules. The equation used to calculate the rms velocity is:

Vrms = √3RT / M

155°C = 155 + 273 = 428 K

'M' is molar mass

Vrms N₂ = √3R × 428 / 28      (1)

Vrms H₂ = √3RT / 2                (2)

From the equation (1) and (2),

√3RT / 2  = √3R × 428 / 28

3RT / 2 = 3R × 428 / 28

T = 30. 57 K

In the peak of summer, it hasn't rained in a week, and the plants are looking rough, so watering the plants for an hour is a good idea.

However, the next day, you come back to the garden, and the plants look in worse shape than they did previously, as if none of that water made it to the plant. Plants absorb water through their roots. The root system of a plant is responsible for drawing water and nutrients from the soil. A plant's root system must be able to absorb water quickly in order for the plant to grow and thrive. When the soil around the root system is dry, the roots will stop growing and will not be able to absorb water.

It may even start to die. Watering plants during the peak of summer is important because it will help keep the soil moist and prevent the roots from drying out. However, watering a plant too much can be harmful. If a plant is overwatered, the water may not be able to penetrate the soil and reach the roots. Instead, it may just sit on top of the soil, causing the roots to rot and die. This can cause the plant to wilt and die.To summarize, if the soil around the plant is too dry, the roots may not be able to absorb the water you gave them, causing the plant to look worse than before. Conversely, overwatering can also be harmful because the water may not be able to penetrate the soil and reach the roots, causing the roots to rot and die.

Explanation:

because when you fire the cannon the cannon ball and powder exit the cannon then that leaves the cannon ball and i would say that the explosion would force it out the cannon but would not increase its mass.

The magnetic force vector on the particle is (-350.00 î + 50.00 j) N. Option D) (-350 î + 50.0ỉ) is the correct answer. we can use the equation: F = q * (v x B)

To find the magnetic force on a charged particle moving in a magnetic field, we can use the equation:

F = q * (v x B)

where F is the magnetic force vector, q is the charge of the particle, v is the velocity vector, and B is the magnetic field vector.

Given:

q = -5.00 C (charge of the particle)

v = (1.00 î + 7.00 j) m/s (velocity of the particle)

B = 10.00 T (magnetic field)

Substituting the values into the equation:

F = (-5.00 C) * ((1.00 î + 7.00 j) m/s x (10.00 T) î)

The cross-product of the velocity vector and the magnetic field vector can be calculated as:

v x B = (v_y * B_z - v_z * B_y) î + (-v_x * B_z + v_z * B_x) j + (v_x * B_y - v_y * B_x) k

Substituting the values:

v x B = (7.00 * 10.00) î + (-(1.00 * 10.00)) j + ((1.00 * 7.00) - (7.00 * 1.00)) k

= 70.00 î - 10.00 j + 0.00 k

= 70.00 î - 10.00 j

Now, calculating the magnetic force:

F = (-5.00 C) * (70.00 î - 10.00 j)

= -350.00 î + 50.00 j

Therefore, the magnetic force vector on the particle is (-350.00 î + 50.00 j) N. Option D) (-350 î + 50.0ỉ) is the correct answer.

Answer:

6 teaspoons of baking powder required.

Explanation:

Given that

According to the recipe of pancake,

For every \(\frac{1}{3}\) teaspoon of salt, 2 teaspoons of baking baking powder is required.

To find:

How much baking powder will be needed, if 1 teaspoon of salt was used ?

Solution:

This problem can be solved using ratio.

\(\frac{1}3\) teaspoon of salt : 2 teaspoons of baking powder

Let us multiply the above ratio with 3.

\(\frac{1}{3}\times 3\) teaspoon of salt : 2 \(\times\) 3 teaspoons of baking powder

OR

1 teaspoon of salt : 6 teaspoons of baking powder

So, answer is 6 teaspoons of baking powder required.

Also, we can use the unitary method:

\(\frac{1}3\) teaspoon of salt needs =  2 teaspoons of baking powder

1  teaspoon of salt needs =  \(\frac{2}{\frac{1}3}\) teaspoons of baking powder

1  teaspoon of salt needs = 2 \(\times\) 3 = 6  teaspoons of baking powder needed

So, the answer is:

6 teaspoons of baking powder required.

Answer:

6 teaspoons of baking powder

Explanation:

This is a simple ratio question.

Every 1/3 of a teaspoon of salt requires 2 teaspoons of baking powder.

Therefore, 1 teaspoon of salt will require:

                               =  1 x 2/1/3

                                    = 2 x 3 = 6 teaspoons of baking powder

Hence, 6 teaspoons of baking powder would be needed if they had used 1 teaspoon of salt.

The relative humidity at the surface  is 63.55%. Relative Humidity (RH) refers to the measure of the degree of water vapor present in the atmosphere as compared to the maximum amount of water vapor required for saturation at that temperature.

In order to determine the relative humidity at the surface of the given problem, we will first need to determine the saturation vapor pressure at

-16.9°C.1.

Using the Tetens formula, we get;

es = \(6.11 × 10 ^ ((7.5T)/(T + 237.3))\)

Here,

T = -\(16.9°Ces = 6.11 × 10 ^ ((7.5(-16.9))/( -16.9 + 237.3))= 1.07 kPa2\).

Using the Clausius-Clapeyron relation, we get;

e = \(es × e^[-L/R (1/T - 1/T0)]\)

Here, L is the latent heat of vaporization of

water = \(2.45 × 10 ^ 6 J/kg\)

R is the specific gas constant for water

vapor = 461.5 J/kg K.1/T

is the Kelvin temperature at which es occurs,

i.e. (-16.9 + 273) = 256 K.1/T0

is the Kelvin temperature of the surface dew point temperature,

i.e. \((12 + 273) = 285 K.e = 1.07 kPa × e^[-(2.45 × 10 ^ 6 / 461.5)(1/256 - 1/285)]= 0.68 kPa3.\)

The relative humidity at the surface is given by;

RH = (e/es) × 100RH = (0.68/1.07) × 100= 63.55%

Therefore, the relative humidity at the surface of the given problem is 63.55%.
