Answer:
Independent variable - temperature
Dependent variable - tablet dissolving affect.
Explanation:
The Independent variable in an experiment is characterized as the variable in the experiment that is not affected by a change in any other variable or factor. It could be changed or manipulated to observe its impact on the dependent variable. While a dependent variable is the one that is affected by any change in the independent variable.
In the given experiment, the 'temperature' is the independent variable as it can be controlled or manipulated to observe the effect in the dependent variable. The 'tablet dissolving effect' would be the dependent variable as it is directly affected by any change in the independent variable(the higher the temperature, the easier the tablet gets dissolved).
Answer:
5.01 J
Explanation:
At the top of the cliff, the lemming has potential energy and kinetic energy.
When it lands, all the energy is converted to kinetic energy.
Final energy = Initial energy
KE = PE₀ + KE₀
KE = mgh + ½ mv₀²
KE = (0.0780 kg) (9.8 m/s²) (5.36 m) + ½ (0.0780 kg) (4.84 m/s)²
KE = 5.01 J

Answer:
The correct answer is D
Explanation:
The kind of weather would an occluded front likely bring is much precipitation. The correct option is (b).
An occluded front happens when a warm front is passed by a cold front, which causes the cold air mass to elevate the warm air mass off the ground. Cloud formation and precipitation may result from this lifting of warm air.
When heated air is hoisted into the atmosphere and cooled, it condenses to form clouds. Ultimately results in rain or different types of precipitation.
Therefore, an occluded front is feasible to produce a good amount of precipitation. Depending on the atmospheric instability, cloudy skies, rain or showers, and occasionally thunderstorms can be found along an occluded front.
Hence, the kind of weather would an occluded front likely bring is much precipitation. The correct option is (b).

An oscilloscope measures time-varying waveform. Electrical input signal is concerted into detectable trace on a screen by converting electricity into light. Time period is plotted along the x -axis as the horizontal component. The center vertical line (y-axis) represents the voltage.
Answer: Option (C) is the correct answer.
Explanation:
Sodium has atomic number 11 and its electronic distribution is 2, 8, 1. Whereas chlorine has atomic number 17 and its electronic configuration is 2, 8, 7.
Therefore, we can see that sodium has one extra electron and chlorine has deficiency of one electron.
So, in order to complete their octet sodium will give its one valence electron to the chlorine atom. Hence, there is exchange of electrons and thus it will result in the formation of ionic bond.
Thus, we can conclude that in sodium chloride electron movement is related to the bonding as electrons exchange creating ions to form an ionic bond by electrostatic attraction.
