PLS HELP FASTWhich element has 1 valence electron in its outer shell and will react with a group 17 element

Answers

The element that has 1 valence electron in its outer shell and will react with a group 17 element (also known as a halogen) in a 1:1 ratio is Potassium (K).

The correct answer is option B.

Potassium belongs to Group 1 of the periodic table, also known as the alkali metals. The alkali metals have one valence electron in their outermost shell, making them highly reactive. In the case of Potassium, it has an electron configuration of 2-8-8-1, with the valence electron being in the outermost shell.

Group 17 elements, on the other hand, are known as halogens and have seven valence electrons. They are highly reactive and tend to gain one electron to achieve a stable electron configuration of a noble gas. When reacting with alkali metals, halogens achieve a stable configuration by accepting the alkali metal's single valence electron, forming an ionic compound.

In the case of Potassium, it will react with a group 17 element in a 1:1 ratio. For example, it can react with Chlorine (Cl) to form Potassium Chloride (KCl). Potassium will lose its single valence electron to chlorine, which will gain the electron to form a stable chloride ion.

A tank contains 2 m3 of air at -93°C and a gage pressure Ro6 of 1.4 MPa. Determine the mass of air, in kg. The local atmospheric pressure is 1 atm

Answers

To determine the mass of air in the tank, we need to convert the given parameters and apply the ideal gas law. The mass of air in the tank is approximately 5.04 kg.

To determine the mass of air in the tank, we need to consider the ideal gas law and convert the given parameters to appropriate units.

Given:

Volume of air (V) = 2 m³

Temperature (T) = -93°C

Gauge pressure (P) = 1.4 MPa

Local atmospheric pressure (P_atm) = 1 atm

First, let's convert the temperature from Celsius to Kelvin:

T = -93°C + 273.15 = 180.15 K

Next, we need to convert the gauge pressure to absolute pressure by adding the atmospheric pressure:

P_abs = P + P_atm = 1.4 MPa + 1 atm = 2.4 MPa

Now, we can use the ideal gas law equation to calculate the mass of air (m):

PV = nRT

Where:

P = absolute pressure

V = volume

n = number of moles of air

R = ideal gas constant

T = temperature

Rearranging the equation to solve for mass (m):

m = (n * M) / N_A

Where:

M = molar mass of air

N_A = Avogadro's number

To find the number of moles (n), we can use the equation:

n = PV / RT

Given that the molar mass of air is approximately 28.97 g/mol, and the ideal gas constant R is 8.314 J/(mol·K), we can calculate the mass of air.

Calculations:

n = (P_abs * V) / (R * T)

m = (n * M) / N_A

Substituting the values:

n = (2.4 MPa * 2 m³) / (8.314 J/(mol·K) * 180.15 K)

m = (n * 28.97 g/mol) / 6.022 x 10^23 mol⁻¹

Calculating the mass of air (m):

m ≈ 5.04 kg

Therefore, the mass of air in the tank is approximately 5.04 kg.

Answers

The elastic potential energy stored in the spring when it is extended to length x3 can be calculated using the formula U = (1/2)k(x3 - x1)².

The elastic potential energy stored in the spring when it is extended to length x3 can be calculated using Hooke's Law and the formula for elastic potential energy.

Hooke's Law states that the force exerted by a spring is directly proportional to the displacement from its equilibrium position. Mathematically, this can be expressed as F = -kx, where F is the force, k is the spring constant, and x is the displacement.

To calculate the elastic potential energy stored in the spring, we can use the formula U = (1/2)kx², where U is the elastic potential energy and x is the displacement.

In this case, the spring is extended to a length of x3, which means the displacement is x3 - x1, where x1 is the equilibrium length. Substituting this into the formula, we get U = (1/2)k(x3 - x1)².

How many kg/m3 to g/cm3?

Answers

To convert kg/m3 to g/cm3, divide by 1000 because a kilogramme contains 1000 grammes and (100 cm)3 Equals 1 m3. So 1 kg/m3 equals 1/1000 g/cm3.

To convert from kg/m3 to g/cm3, just multiply the value in kg/m3 by 1000. We may use the conversion ratio 1 kg/m3 = 1/1000 g/cm3 to convert density units from kg/m3 to g/cm3. For example, if we have a density of 5 kg/m3, we can convert it to g/cm3 by doing the following: 5 kg/m3 equals 5/1000 g/cm3 = 0.005 g/cm3. Instead, we may convert units using dimensional analysis. We may devise a conversion factor based on the equivalency of 1 kg and 1000 g, as well as 1 m3 and (100 cm)3: 1 kg = 1000 g m³ = (100 cm)³ = 10^6 cm³ Then, we can multiply the density in kg/m³ by the conversion factor, making sure to cancel out the units of kg and m³:

a 1200-kg cylindrical can buoy floats vertically in salt water. the diameter of the buoy is 0.9 m. calculate the additional distance the buoy will sink when a 80-kg man stands on top

Answers

To calculate the additional distance the buoy will sink when a man stands on top, we need to consider the change in buoyancy force and the additional weight added to the system.

The buoyancy force is equal to the weight of the fluid displaced by the buoy. In this case, since the buoy is floating vertically, the buoyancy force is equal to the weight of the buoy itself.

Buoyancy force = Weight of the buoy = Mass of the buoy * Gravitational acceleration

Buoyancy force = 1200 kg * 9.8 m/s^2 = 11,760 N

When the man stands on top of the buoy, his weight is added to the system. The additional weight is:

Additional weight = Mass of the man * Gravitational acceleration

Additional weight = 80 kg * 9.8 m/s^2 = 784 N

The additional weight will increase the total weight of the system, and consequently, the buoyancy force will also increase.

The additional distance the buoy will sink can be calculated using Archimedes' principle, which states that the buoyant force is equal to the weight of the fluid displaced by the object.

Additional distance = Additional weight / (Cross-sectional area * Fluid density)

The cross-sectional area of the buoy can be calculated using the diameter:

Cross-sectional area = π * (Diameter/2)^2 = π * (0.9 m / 2)^2

Assuming the fluid density of saltwater is 1025 kg/m^3, we can substitute the values into the equation:

Additional distance = 784 N / (π * (0.9 m / 2)^2 * 1025 kg/m^3)

Calculating the additional distance will provide the specific value based on the given dimensions and assumptions.

In summary, to find the additional distance the buoy will sink when a man stands on top, we consider the change in buoyancy force due to the added weight. By using Archimedes' principle, the additional distance can be calculated by dividing the additional weight by the cross-sectional area of the buoy multiplied by the fluid density.

Scientists have observational evidence of black holes through indirect methods, such as studying the effects of their strong gravitational pull on surrounding matter, detecting X-rays emitted from accretion disks.

Black holes, by definition, cannot be observed directly since no light or information can escape their gravitational pull. However, scientists have gathered compelling evidence for their existence through indirect observations. One such method involves studying the effects of black holes on surrounding matter. As matter falls into a black hole's gravitational field, it forms an accretion disk that emits X-rays detectable by space telescopes. Additionally, the detection of gravitational waves, ripples in spacetime caused by the acceleration of massive objects, provides strong evidence for the existence of black holes. Advanced detectors like LIGO and Virgo have successfully observed gravitational waves generated by black hole mergers, confirming their presence in the universe.

C.The tennis balls are too small to produce any gravity.
D.There is too much friction between the balls and the ground
(the picture is just of the question)

Answers

Answer:

Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces. So as two objects are separated from each other, the force of gravitational attraction between them also decreases.

When dealing with the force of gravity between two objects, there are only two things that are important – mass, and distance. The force of gravity depends directly upon the masses of the two objects, and inversely on the square of the distance between them.

The acceleration that the same net force would give to an 18-kg tool is 13.3 m/s² (meters per second squared).

Define Newton's second law of motion?

According to Newton's second law of motion, the acceleration of an object is directly proportional to the net force applied to it and inversely proportional to its mass.

Mathematically, this can be expressed as F = ma, where F is the net force, m is the mass, and a is the acceleration.

In the given scenario, the net force is accelerating a 4.8-kg tool at 40 m/s². To find the acceleration for an 18-kg tool, we can rearrange the equation to solve for a:

a = F/m

Substituting the values, we have:

a = (F)/(18 kg) = (40 m/s²)/(18 kg) = 2.22 m/s²

Therefore, the net force would give an acceleration of 2.22 m/s² to an 18-kg tool.

three equal negative point charges are placed at three of the corners of a square of side d . what is the magnitude of the net electric field at the center of the square? ( k

Answers

The magnitude of the net electric field at the center of the square is zero.

When three equal negative point charges are placed at three corners of a square, the forces exerted by the charges cancel each other out at the center of the square, resulting in a net electric field of zero.

Each negative charge creates an electric field that points radially away from it. At the center of the square, the electric fields from the three charges will have equal magnitudes but opposite directions. Due to the symmetry of the system, the vectors representing the electric fields will cancel each other out, resulting in a net electric field of zero.

This cancellation of electric fields at the center of the square is a consequence of the equal magnitudes and positioning of the charges. If the charges were not equal or if they were not positioned symmetrically, the net electric field at the center of the square would not be zero.

In summary, the presence of three equal negative point charges at the corners of a square leads to the cancellation of electric fields at the center, resulting in a net electric field of zero.

A rectangular block of sides 5.0 cm x 10.0cm x 20.0cm is made of material of density 2.50 g/cm³. Find the pressure it can exert resting with the sides 5.0 cm and 10.0cm on a horizontal surface. [g= 10 m/s² or 1000 cm/s²] ​

Answers

The rectangular block exert a pressure of 500,000 Pascals on the horizontal surface with its sides measure out 5.0 cm and 10.0 cm.

To calculate the pressure exert out by the rectangular block on the horizontal surface, take the formula:

Pressure = weight ÷ area

In which:

Weight = mass × gravity

Mass = density × volume

Area = length × width

According to question:

Density of the material = 2.50 g/cm³

Dimensions of the block:

Length = 5.0 cm

Height = 20.0 cm

Width = 10.0 cm

Gravity = 1000 cm/s²

Firstly, convert the dimensions from centimeters to meters:

Length = 5.0 cm

= 5.0 cm ÷ 100 = 0.05 m

Width = 10.0 cm

= 10.0 cm ÷ 100 = 0.10 m

Height = 20.0 cm

= 20.0 cm ÷  100 = 0.20 m

Next, find the mass of the block:

Volume = length × width × height

Volume = 0.05 m × 0.10 m × 0.20 m

= 0.001 m³

Mass = density × volume

Mass = 2.50 g/cm³ × 0.001 m³

= 2.50 kg

Now, find the weight of the block:

Weight = mass × gravity

Weight = 2.50 kg × 1000 cm/s²

= 2500 N

At the last find the pressure:

Area = length × width

Area = 0.05 m × 0.10 m

= 0.005 m²

Pressure = weight ÷ area

Pressure = 2500 N ÷ 0.005 m²

= 500,000 Pa

Therefore, the rectangular block exert a pressure of 500,000 Pascals on the horizontal surface with its sides measure out 5.0 cm and 10.0 cm.

An open, clean glass tube (theta=0°)is inserted vertically into a pan of water at 60 °F.What tube diameter(in ft)is needed if the water level in the tube is to rise one tube diameter (due to surface tension)? Give your answer in feet.

Answers

The diameter of the tube needed for the water level to rise one tube diameter due to surface tension is approximately 1/12 inch, calculated using the formula d = 2T cos(θ) / (ρgh) where T, θ, ρ, and g are given values.

The rise of the water level in the tube due to surface tension is given by the formula:

h = 2T cos(θ) / (ρgd)

where h is the rise in the water level, T is the surface tension of water, θ is the contact angle (in this case, θ = 0°), ρ is the density of water, g is the acceleration due to gravity, and d is the diameter of the tube.

We can rearrange this formula to solve for d:

d = 2T cos(θ) / (ρgh)

where we have used g = 32.2 ft/s^2 as the acceleration due to gravity and ρ = 62.4 lb/ft^3 as the density of water at 60 °F.

The surface tension of water at 60 °F is approximately T = 5.11 x 10^-2 lb/ft.

Substituting the given values into the formula for d, we get:

d = 2 * 5.11 x 10^-2 lb/ft * cos(0°) / (62.4 lb/ft^3 * 32.2 ft/s^2 * 1 ft) ≈ 0.001 ft

then force becomes mg

that is F=Mg

=4*9.8

then by using the formula

F=Ma

a=F/M

=4*9.8/9.8

=4

Explanation:

Mass=9.8kgForce=4N

Using newtons second law

\(\\ \bull\sf\dashrightarrow Force=Mass\times Acceleration\)

\(\\ \bull\sf\dashrightarrow Acceleration=\dfrac{Force}{Mass}\)

\(\\ \bull\sf\dashrightarrow Acceleration=\dfrac{9.8}{4}\(

\(\\ \bull\sf\dashrightarrow Acceleration=2.45m/s^2\)
