Answer:
Mass of object (m) = 5.102 kg
Explanation:
Given:
Horizontal Force (F) = 50 N
Find:
Mass of object (m) = ?
Computation:
We know that, acceleration due to gravity (g) = 9.8 m/s²
⇒ Horizontal Force (F) = mg
⇒ 50 N = m (9.8 m/s²)
⇒ Mass of object (m) = 50 / 9.8
⇒ Mass of object (m) = 5.102 kg
Mass of object (m) is 5.1 kg (Approx)
The major shortcoming of Rutherford's model was that it was incomplete. It did not explain how the atom's negatively charged electrons are distrubuted in the space surronding its positively charged nucleus. A form of energy that exhibits wavelike behavior as it travels through space
Answer:
13.4cm
Explanation:
According to Rayleigh’s criterion the angular resolution to distinguish two objects is given by:

θ = 50.0*10^-7 rad
λ: wavelength of the light = 550nm
b = diameter of the objective
By doing b the subject of the formula and replacing the values of the angle and wavelength you obtain:

hence, the smallest diameter objective lens is 13.4cm
Endless movement between hot and cold will eventually mean the end of the universe. This law is about inefficiency, degeneration and decay. <u>The second law can be expressed in several ways, the simplest being that heat will naturally flow from a hotter to a colder body. At its heart is a property of thermodynamic systems called entropy.</u> Entropy basically means an increase in randomness. Hope this helps mate.
