Answer and Explanation:
The rate (in W) at which heat energy moves from the more blazing article to the colder item increments with the temperature distinction between the items.
The more noteworthy the temperature contrast, the more prominent the rate at which exchange of heat energy takes place.
Thus the temperature difference between the beakers relates in the same manner as described above.
The exchange of heat energy continues until a thermal equilibrium is attained.
Chemical to thermal to electrical current: Burning of coal or natural gases. Gravitational potential to kinetic to electrical current.
Answer:
a) Electric potential = 853 V
b) Electron speed at point B, if at Point A, the speed were zero = 1.732 × 10⁷ m/s
Explanation:
For an electron moving in an electric field with potential V,
Work done = qV where q is the charge on the electron
And the Work done is equal to the change in kinetic energy of the electron
qV = m(v₂² - v₁²)/2
V = m(v₂² - v₁²)/2q
q = 1.602 × 10⁻¹⁹C
m = 9.11 × 10⁻³¹ kg
v₁= 10⁷ m/s
v₂ = 2 × 10⁷ m/s
Putting these values in for the variables and solving
V = 853 V
b) If the electron started from rest,
qV = mv²/2
v = √(2qV/m) =√((2 × (1.602 × 10⁻¹⁹) × 853)/(9.11 × 10⁻³¹)) = 1.732 × 10⁷ m/s
Answer:
The largest equivalent resistance yu can build using these three resistors is a Serie Resistance with the value of R= 16.74 Ω
Explanation:
Adding Resistances in serie is the way to build de largest equivalent value possible.
Rt= R1+R2+R3
Rt= 6.32 + 8.13 + 2.29
Rt= 16.74Ω
The electrical potential energy of a particle in a uniform electric field depends on 1) the charge of the particle 2) the distance from the source of the field 3) the magnitude of the electric field
In fact, the electrical potential energy is defined as
(1)
where q is the charge and V is the voltage. Since the electric field is uniform, the voltage increase linearly with the distance from the source:
(2)
where E is the electric field strength and d is the distance. Putting (2) into (1), we find
therefore, we see that the potential energy of the particle depends on the charge q, the distance d from the source and the electric field strength E (which is constant at every location, because the field is uniform)
