Formula of

Line segment

is AB =

\(\sqrt{(x_{2} -x_{1} )^{2} } +\sqrt{(y_{2} -y_{1} )^{2} }\)

Line segment

is a part of line with definite length. It has two ending points whereas a line has no end points and extended infinitely in both the direction. Line which joins both ending points with possible shortest way is known as

Line segment

.

            A ______________________ B    

        (x₁,y₁)                                             (x₂,y₂)      

This line segment can be represented as \(\frac{}{AB} /\frac{}{BA}\). In other word we can say line segment is

subset

of line, so it contains all the points of line lying between both end point of segment. For shorter length it can simply measure by

ruler

We have been asked to determine the maximum height reached by the object .

For calculating the maximum height attained by the object we will use the following formula .

Answer:

1. When a cold air mass and a warm air mass meet but are at a standstill, the boundary is called stationary front.

2. If warm or more humid air presses forward and colder or drier air draws back, the boundary is called warm front.

3. If colder or drier air presses forward and warmer or more humid air draws back, the boundary is called cold front.

4. Sometimes a warm air mass can get caught between two cold fronts, which can force the warm air up into a wedge shape is called occluded front.

Explanation:

A stationary front is created when two air masses of different temperatures come together but remain stationary. A warm front is created when warmer, more humid air pushes forward and cooler, drier air pulls back.

A front in a physical system can be thought of as the boundary between two distinct possible states (either stable or unstable). When two air masses with different temperatures come together but stay stationary, a stationary front is formed.

The correct matches are:

Therefore, When cooler, drier air pulls back and warmer, more humid air rushes forward, a warm front is formed.

Satellites have made ground-based weather stations almost obsolete is false.

While satellites have greatly enhanced weather monitoring and forecasting capabilities, ground-based weather stations still play a crucial role in collecting detailed and localized weather data. Ground-based weather stations provide valuable information such as temperature, humidity, wind speed, precipitation, and atmospheric pressure at specific locations. This data helps validate and calibrate satellite observations and provides essential information for accurate weather predictions and climate studies. Ground-based weather stations also contribute to monitoring and understanding local weather patterns, microclimates, and phenomena that may not be captured by satellite imagery alone.

In words, the R2 of 0.27 means that 27% of the variability in y (24-hour urinary Na) can be explained by x (estimated 24-hour urinary Na) obtained from casual urine specimens at one point in time.

The INTERSALT Study was designed to investigate the relationship between dietary sodium and blood pressure (hypertension) in populations worldwide.

The study included 10,079 men and women from 52 population samples in 32 countries. One of the goals of the study was to quantify the relationship between 24-hour urinary Na (y) and estimated 24-hour urinary Na (x) obtained from casual urine specimens at one point in time.

The investigators presented a simple linear regression of y on x, separately for men and women. The regression equation for men was: Y = 1.03x + 7.19, with R2 = 0.27, n = 1369.

The coefficient of determination, R2, is a statistical measure that represents the proportion of the variance for a dependent variable (y) that's explained by an independent variable (x) or variables in a regression model.

In this case, the R2 of 0.27 means that 27% of the variability in y (24-hour urinary Na) can be explained by x (estimated 24-hour urinary Na) obtained from casual urine specimens at one point in time. The remaining 73% of the variability in y is due to other factors that are not included in the regression model.

The correct answer is D. Amount of time and area of physical contact between the substances.

Explanation:

Heat transfer refers to the flow of thermal energy or heat between two or more objects. This process involves multiple factors and implies heat from the hottest object goes to the coldest one until there is an equilibrium. To begin, heat transfer depends on the amount of thermal energy in the objects because objects must have a different amount of thermal energy for heat to flow.

Besides this, the amount of energy that flows depends on the time and the contact between the substances of objects. Indeed, objects need to be in contact or close to each other for heat to transfer, and the time needs to be enough for the process to occur. For example, if you place a pot over the fire just for a few seconds it is likely the heat transferred is minimal, which does not occur if you leave the pot more time. At the same time if the pot is in close contact with fire more heat will be transferred.-

During the phase transition from liquid to gas, the temperature of the object remains constant despite continuous heating. The energy supplied to the object is used to break the intermolecular forces holding the liquid molecules together rather than increasing the temperature.

During the phase transition from liquid to gas, the temperature of the object remains constant at the boiling point of the substance. This phenomenon is known as the latent heat of vaporization. As heat is supplied to the liquid, the energy is used to break the intermolecular forces between the molecules, allowing them to overcome the attractive forces and transition into the gas phase.

While the energy is being absorbed by the liquid to undergo the phase transition, the temperature does not increase. Instead, it remains constant until the entire substance has transitioned to the gas phase. This is because the energy supplied is utilized in the process of changing the state of the substance rather than increasing the kinetic energy of the individual molecules, which would result in a temperature increase.

Once the phase transition is complete, any additional energy supplied will result in an increase in temperature as the gas molecules gain kinetic energy. Thus, the phase transition from liquid to gas involves a constant temperature and a transfer of energy to break intermolecular forces rather than a change in the object's temperature.

The other focus of the Sun will be Nothing, hence option C is the correct answer. See more explanation below.

The other focus of Earth's elliptical orbit is empty space because an ellipse is defined as a set of points in a plane, such that the sum of the distances from any point on the curve to two fixed points (the foci) is a constant. Because the Sun is located at one of the foci, the other focus must be empty space.

The orbit of the Earth is also shaped like an ellipse, which is a closed curve that is widened and flattened in one direction. The point where the ellipse is most stretched out is its focus, and the point where it is most flattened is its other focus. One of the foci is where the Sun is, and the other is just empty space.

A  it is still at the same passe and it is going back down

Explanation:

Answer:

The correct answer to your question is A. The object is moving at a constant, negative, velocity. It is negative because it is moving back towards the origin.

Explanation:

Answer:

a) y = 103.21 m

b) t = 4.6 s

Explanation:

a) The height at which the balls was is given by:

\( V_{f}^{2} = V_{0}^{2} - 2g(y_{f} - y_{0}) \)

Where:

\(y_{f}\): is the final height = 0

\(y_{0}\): is the initial height =?

\(V_{f}\): is the final velocity = 45 m/s

\(V_{0}\): is the initial velocity = 0 (is held at rest

g: is the gravity = 9.81 m/s²          

Hence, the height is:

\( y_{0} = \frac{V_{f}^{2}}{2g} = \frac{(45 m/s)^{2}}{2*9.81 m/s^{2}} = 103.21 m \)

b) The time before the ball hit the ground is:

\( V_{f} = V_{0} - g*t \)

\( t = -\frac{V_{f}}{g} = -\frac{- 45 m/s}{9.81 m/s^{2}} = 4.6 s \)

Therefore, 4.6 seconds passed before the ball hit the ground.
