Answer:
(a) 8.2 x 10^-8 N
(b) 3.6 x 10^-47 N , 2.27 x 10^39
Explanation:
charge of proton, q1 = 1.6 x 10^-19 C
charge of electron, q2 = - 1.6 x 10^-19 C
radius of orbit, r = 0.053 nm = 0.053 x 10^-9 m
mass of electron, me = 9.1 x 10^-31 kg
mass of proton, mp = 1.67 x 10^-27 kg
Gravitational constant, G = 6.67 x 10^-11 Nm^2/kg^2
(a) The electrostatic force between two charges is given by
Where, K is the coulombic constant = 9 x 10^9 Nm^2/C^2
By substituting the values
Fe = 8.2 x 10^-8 N
(b) The gravitational force between the electron and proton is given by
Fg = 3.6 x 10^-47 N
1). the product of the two masses being gravitationally attracted to each other
2). the distance between their centers of mass
And that's IT. The gravitational force between them depends on
only those two things, nothing else.
Answer:
The answer is given as follows,
Explanation:
Gold large-sized weight 100 g < M < 250g
50 g < Magenta small-sized weight < 100g
100g < Blue medium-sized weight < 250g
Hence,
100g < Blue medium-sized weight < 250g
50 g < Magenta small-sized weight < 100g
100 g < Gold large-sized weight < 250g.
Based on the data provided, the thermal energies at the given time intervals are as follows:
- At time t = 0.0 secs; thermal energy = 0.0 J
- At time, t = 0.8 secs; thermal energy = 0.0 J
- At time, t = 2.0 secs; thermal energy = 3.9 J
- At time, t = 2.8 secs; thermal energy = 6.7 J
<h3>What is the law of conservation of energy?</h3>
The law of conservation of energy states that the total energy in an isolated system is conserved.
For a ball undergoing energy conversion between kinetic and potential energy, the sum of the energy remains constant.
Any reduction in total energy is due to conversion of some energy to thermal energy.
- Sum of energy: Kinetic + potential + thermal = 15.2 J
- Thermal energy = 15.2 - (PE + KE)
At time t = 0.0 secs
Thermal energy = 15.2 - (15.2 + 0.0)
Thermal energy = 0.0 J
At time, t = 0.8 secs
Thermal energy = 15.2 - (4.7 + 10.5)
Thermal energy = 0.0 J
At time, t = 2.0 secs
Thermal energy = 15.2 - (7.4 + 3.9)
Thermal energy = 3.9 J
At time, t = 2.8 secs
Thermal energy = 15.2 - (8.5 + 0.0)
Thermal energy = 6.7 J
Therefore, the thermal energies at the given time intervals are as follows:
- At time t = 0.0 secs; thermal energy = 0.0 J
- At time, t = 0.8 secs; thermal energy = 0.0 J
- At time, t = 2.0 secs; thermal energy = 3.9 J
- At time, t = 2.8 secs; thermal energy = 6.7 J
