Answer:
A longitudinal study is a observational study that follows the same subjects repeatedly over a period of time, in some cases from birth to death
or
the same adults are tested at each time point: 20, 30, and 40 years of age
Answer:
The greatest acceleration when the unbalanced force is applied will be experienced in :
A) The box with a mass of 2 kg
Explanation:
According to second law of motion the external unbalanced force is directly proportional to rate of change of momentum.
F = (Final momentum - initial momentum)/time
or
Force is equal to the product of mass and acceleration
F = m x a
Here a= acceleration
m = mass of the object
If Force is constant then acceleration is inversely proportional to mass

A) The box with a mass of 2kg
F = 8 N

a = 4 m/s2
B) The box with the mass of 4kg

a = 2 m/s2
C) The box with a mass of 6kg

a = 1.33 m/s2
D) The box with a mass of 8kg

a = 1 m/s2
Carbon can form a maximum of 4 covalent bonds because it has 4 valence electrons i.e. 4 outer electrons.
Answer:
Some signs of a chemical change are a change in color and the formation of bubbles. The five conditions of chemical change: color change, formation of a precipitate, formation of a gas, odor change, temperature change.
The temperature in in Celsius is 5826.85 degree Celsius and Fahrenheit is 10520.33.
To express temperature in kelvin and Celsius two different relations are used, The formula to convert Fahrenheit to Celsius we use the formula T(K) = (T(°F) + 459.67)× 5/9 here T(k) mean temperature in kelvin and T(F) is temperature in Fahrenheit so by putting the given data we get (6100 − 273.15) × 9/5 + 32 = 10520.33°F and so now we obtained the temperature in kelvin so to convert kelvin to Celsius we use this formula °C=K−273.15, so by putting the given data 6100 − 273.15 = 5826.85°C.Kelvin, Celsius and Fahrenheit are the three units to measure the temperature.
