Answer:
2993 °C
Explanation:
A reaction is spontaneous if the free Gibbs energy (ΔG) is negative. ΔG is related to the enthalpy of the reaction (ΔH) and the entropy of the reaction (ΔS) through the following expression.
ΔG = ΔH - T . ΔS
For 1 mol, if ΔG < 0, then
ΔH - T . ΔS < 0
ΔH < T . ΔS
-320.1 × 10³ J < T . (-98.00 J/K)
T < 3266 K
To convert Kelvin to Celsius we use the following expression.
K = °C + 273.15
°C = K - 273.15 = 3266 - 273.15 = 2993 °C
Arrows point away from north and forward south, and Field lines loop around the magnet starting at the North Pole and ending at the South Pole.
I think this is the correct answer, not necessarily sure though.
Answer:
a. v' = 24.22 x 10 ⁻³
b. β = 0.825 T
Explanation:
V = 150 V , E = 6.0 x 10 ⁶ N / C
a.
¹/₂ * m * v² = e * V
v = √ 2 * e / m * V
v = √ 2 * 1.76 x 10 ¹¹ * 150 v = √ 5.28 x 10 ¹³
v = 7.26 x 10 ⁶ m /s
v' / c = 7.26 x 10 ⁶ m /s / 3.0 x 10 ⁸ = 24.22 x 10 ⁻³
b.
β = E / V
β = 6.0 x 10 ⁶ / 7.266 x 10 ⁶
β = 0.825 T
c.
When the increasing the accelerating potential speed it doesn't change the up wired the electric force and the magnetic force the electron be beat down more .
Answer: Symbol A
Explanation:
The four symbols described here represent:
- Symbol A shows two dots and a line draw from one not connected to the other. --> this is an open switch. A switch is component of a circuit that is used to open/close the circuit in order to interrupt/allow the flow of current through the circuit. In this case, the switch is open, since the line does not connect the second dot.
- Symbol B shows two dots and a line draw from one connected to the other. --> this is the symbol used to represent the switch when it is closed, so it is a closed switch.
- Symbol C shows vertical lines in the pattern long, short, long, and short with a plus and minus symbol on it. --> this symbol represents a battery, which consists of two or more cells and provides the electromotive force that pushes the electrons along the circuit.
Therefore, the correct symbol representing the open switch is
Symbol A
