Explanation:

When two massless springs of force constants k1 and k2 are joined end to end, the resultant force constant k of the system can be calculated.

In this configuration, the springs are connected in series. For springs connected in series, the resultant force constant is given by the reciprocal of the sum of the reciprocals of the individual force constants:

1/k = 1/k1 + 1/k2

To find k, we take the reciprocal of both sides of the equation:

k = 1 / (1/k1 + 1/k2)

To simplify the expression, we can use the concept of the least common denominator:

k = 1 / ((k2 + k1) / (k1 * k2))

  = k1 * k2 / (k1 + k2)

Therefore, the resultant force constant k of the system is given by

k1 * k2 / (k1 + k2).

When two massless springs of force constants k1 and k2 are joined end to end in series, the resultant force constant k of the system is given by k = k1 * k2 / (k1 + k2). This can be derived using the formula for springs connected in series, which states that the reciprocal of the resultant force constant is equal to the sum of the reciprocals of the individual force constants.

Answer:

1. Color, Streak, Luster, Cleavage and fracture, Density, Hardness, Special properties.

2. The term luster refers to the appearance of a fresh surface of a mineral in reflected light. The two basic types of luster are metallic and non-metallic.

3. You test the hardness of a mineral by scratching its surface with a mineral of a known hardness. Mineralogists use Mohs Scale as a reference for mineral hardness. The scale lists common minerals in order of their relative hardness. You can use the minerals in the scale to test the hardness of an unknown mineral.

4. Color is also an unreliable identification clue because weathered surfaces may hide the color of minerals. For example, the golden color of iron pyrite ranges from dark yellow to black when iron pyrite is weathered. When examining a mineral for color, you should inspect only the mineral's freshly exposed surfaces.

5. Most minerals can be characterized and classified by their unique physical properties: hardness, luster, color, streak, specific gravity, cleavage, fracture, and tenacity.

6.  Magnets attract minerals that contain iron. Nonsilicate minerals that contain iron are more likely to be magnetic than other nonsilicate minerals are so testing to see if a mineral is magnetic can show what an element is made of.

The velocity of the other piece of the pinata which has a mass of 3.86 kg

is 0.67 m/s

The mass of the candy-filled pinata = 4.4 kg

The mass of the first piece of the pinata = 0.54 kg

The velocity of the first piece of the pinata = 4.8 m/s

The mass of the second piece = 3.86 kg

The velocity of the other piece can be found using the formula,

          mu = m₁v₁ + m₂v₂

where m is the mass of the pinata

           u is the velocity of the pinata at rest

           m₁,m₂ are the masses of the first and second pieces of pinata

           v₁,v₂ is the velocity of the two pieces

Let us substitute the known values in the above equation, we get

          4.4 x 0 = 0.54 x 4.8 + 3.86v₂

                       = 2.592 + 3.86v₂

            3.86v₂ = -2.592

                    v₂ = 2.592/3.86

                         = 0.67 m/s

When a ball is thrown up in the air, the acceleration of the ball changes throughout its flight. Initially, when the ball is thrown upwards, it experiences a gravitational force pulling it downwards, which causes it to decelerate.

The acceleration of the ball at this point is negative, with a magnitude equal to the acceleration due to gravity (9.81 m/s² near the Earth's surface. As the ball rises higher, the force of gravity acting on it decreases due to the increase in distance from the Earth's center. However, the velocity of the ball is still decreasing, so the ball continues to experience a negative acceleration.

At the highest point of the ball's trajectory (known as the apex), the velocity of the ball becomes zero. At this point, the acceleration of the ball is equal to the acceleration due to gravity, but with a positive sign (since the ball is now moving in the opposite direction to the gravitational force).

The correct answer choice for the explanatory and response variables of a scatterplot depends on the context and the variables being studied.

The correct answer choice for the explanatory and response variables of a scatterplot depends on the context and the variables being studied.

In general, the explanatory variable is the independent variable, which is the variable being manipulated or controlled in the study.

The response variable is the dependent variable, which is the variable being measured or observed in response to changes in the explanatory variable.

For example, if we are studying the relationship between voltage and the rotation of an electric motor, then the explanatory variable would be voltage, and the response variable would be rotation.

As voltage is being manipulated, the resulting changes in the rotation of the motor are being observed and measured.

Conversely, if we are studying the relationship between rotation and the voltage required to achieve that rotation, then the explanatory variable would be rotation, and the response variable would be voltage.

As rotation is being manipulated, the resulting changes in the required voltage are being observed and measured.

It is important to carefully consider the variables and their relationships when interpreting a scatterplot.

Answer:

5,000 kg-m/s going south

Explanation:

Since you're only given mass and height, not velocity. You have to find velocity first. The equation for velocity is v=2gh. We know gravity is 10 since it's given & height is also given which is 125m. After doing the math, it's 2,500. Now that you have velocity, you can plug velocity into the formula for momentum which is p=mv. 2.0 times 2,500 = 5,000 kg-m/s going south.

The time period of the whole wave cycle is 6 seconds but the time period of one complete wave is about 4 seconds here. The inverse of this time period is the frequency, that is 0.2 Hz.

Frequency by definition is the number of events per unit time. Frequency of a wave is the number of wave cycles in one second. It is the inverse of the time period.

Frequency is directly related to the energy of the wave. As the frequency increases, energy of the wave also increases. In the given graph the wave cycle is given for a time of 6 seconds.

The time period for one complete wave  is 4 second from the graph.

thus, T = 4 s

In order to chill a 750mL bottle of champagne using a bucket of ice at 0 degrees Celsius, approximately 249 grams of ice must melt. The specific heat capacity of ice is approximately 2.09 J/g°C.

To determine the amount of ice that needs to melt, we can use the principles of thermodynamics. First, we need to calculate the heat lost by the champagne and the heat gained by the melting ice. The heat lost by the champagne can be calculated using the equation Q = mcΔT, where Q is the heat lost, m is the mass of the champagne, c is the specific heat capacity of champagne, and ΔT is the change in temperature. Similarly, the heat gained by the ice can be calculated using the same equation, where m is the mass of the ice and c is the specific heat capacity of ice.

Given that the initial temperature of the champagne is 25 degrees Celsius and the final temperature is 8 degrees Celsius, ΔT for the champagne is 25 - 8 = 17 degrees Celsius. The specific heat capacity of champagne is approximately the same as water, which is 4.18 J/g°C. Therefore, the heat lost by the champagne is Q = (750g)(4.18 J/g°C)(17°C) = 53,595 J.

Since the ice is at 0 degrees Celsius, ΔT for the ice is 0 - (-8) = 8 degrees Celsius. The specific heat capacity of ice is approximately 2.09 J/g°C. Therefore, the heat gained by the ice is equal to the heat lost by the champagne, which is 53,595 J. Using the equation Q = mcΔT and solving for the mass of ice (m), we can rearrange the equation to m = Q / (cΔT). Plugging in the values, we get m = 53,595 J / (2.09 J/g°C * 8°C) ≈ 249 grams.

Therefore, approximately 249 grams of ice must melt in order to chill the champagne from 25 degrees Celsius to 8 degrees Celsius in a bucket of ice at 0 degrees Celsius.
