Answer:
Part a)
v = 16.52 m/s
Part b)
v = 7.47 m/s
Explanation:
Part a)
(a) when the large-mass object is the one moving initially
So here we can use momentum conservation as the net force on the system of two masses will be zero
so here we can say
since this is a perfect inelastic collision so after collision both balls will move together with same speed
so here we can say
Part b)
(b) when the small-mass object is the one moving initially
here also we can use momentum conservation as the net force on the system of two masses will be zero
so here we can say
Again this is a perfect inelastic collision so after collision both balls will move together with same speed
so here we can say
How much a substance increase its temperature due to heat transfer depends on its specific heat.
The specific heat is the amount of heat required to increase the temperature of one mass of substance in 1 °Celsius.
The lower the specific heat the more the substance change its temperature with a given amount of heat, the greater the specific heat of the substance the lesser the change of temperature with the same amount of heat.
Then, to predict which of the two blocks will have the greater rise you need to compare the specific heats of the metals.
From tables, the specific heat of gold is 0.129 J/g°C and specific heat of iron is 0.450J/g*°C.
Then, gold will raise more its temperature than iron, after the addition of the same amount of heat.
Answer:
The new gravitational pull would be three times as strong as the first which would be 0.000000003 or 3 × 10^-9N.

Answer:
Ionization potential of C⁺⁵ is 489.6 eV.
Wavelength of the transition from n=3 to n=2 is 1.83 x 10⁻⁸ m.
Explanation:
The ionization potential of hydrogen like atoms is given by the relation :
.....(1)
Here <em>E</em> is ionization potential, <em>Z</em> is atomic number and <em>n</em> is the principal quantum number which represents the state of the atom.
In this problem, the ionization potential of Carbon atom is to determine.
So, substitute 6 for <em>Z</em> and 1 for <em>n</em> in the equation (1).
<em> E = </em>489.6 eV
The wavelength (λ) of the photon due to the transition of electrons in Hydrogen like atom is given by the relation :
......(2)
R is Rydberg constant, n₁ and n₂ are the transition states of the atom.
Substitute 6 for Z, 2 for n₁, 3 for n₂ and 1.09 x 10⁷ m⁻¹ for R in equation (2).
= 5.45 x 10⁷
λ = 1.83 x 10⁻⁸ m
