Explanation:

The gravitational force between two objects is given by :

$F=G\dfrac{m_1m_2}{d^2}$

Where

G is universal gravitational constant

d is the distance between two masses

The gravitational force is inversely proportional to the distance between objects. It means when the distance between objects increases, gravitational force decreases and vice versa. To decrease the gravitational force between two objects, distance must increase.

The temperature of a 100.0 g sample of water is raised from 30degrees celsius to 100.0 degrees celsius. How much energy is requi

worty [1.4K]

Answer:

29260J

Explanation:

Given parameters:

Mass of water sample = 100g

Initial temperature = 30°C

Final temperature = 100°C

Unknown:

Energy required for the temperature change = ?

Solution:

The amount of heat required for this temperature change can be derived from the expression below;

H = m c (ΔT)

H is the amount of heat energy

m is the mass

c is the specific heat capacity of water = 4.18J/g°C

ΔT is the change in temperature

Now insert the parameters and solve;

H = 100 x 4.18 x (100 - 30)

H = 100 x 4.18 x 70 = 29260J

The equation of which of the below scientists could be used to find the wavelength of the emission lines of the hydrogen atom:

mihalych1998 [28]

The equation that scientists could use to find the wavelength of the emission lines of the hydrogen atom would be that of Balmer.

The wavelength of the emission lines of the hydrogen atom can be derived using the Balmer series:

1/λ $= R_H (1/4 - 1/n^2)$

Where λ = wavelength, $R_H$ = Rydberg constant, and n = level of the original orbital.

The equation becomes applicable in getting the wavelength of emitted light when electrons in hydrogen atoms transition from higher (n) orbital to lower orbital (2) levels.
