Answer:
the pressure will decrease by 1/2
Explanation:
PV=nRT
P=(nRT)/(V)
nRT are all constant so they will equal 1
V is 2
P=1/2
Gasoline fuel is a renewable alternative to petroleum fuels that is made through either biologically or chemically driven production in a process called gasification.
Answer:
R = 1.79*10^6 Ω
C = 2.46*10^-6 F
Explanation:
Given
emf of the source, ε = 120 V
Current passing through the resistor, I = 6.7*10^-5 A
Time constant for the circuit, τ = 4.4 s
From the information above, we can say that RC = 4.4 s
Also, on applying the loop rule, we get
ε - IR = 0
ε = IR
R = ε / I
R = 120 / 6.7*10^-5
R = 1.79*10^6 Ω
Using the first equation, we can thus solve for C
RC = 4.4 s
C = 4.4 / R
C = 4.4 / 1.79*10^6
C = 2.46*10^-6 F
C = 2.46 μF
Therefore, the resistance and capacitance of the capacitor is respectively, 1.79 MΩ and 2.46 μF
Using the graph, which describes how Henry ran the 100m race;
a) It takes Henry 20seconds to run 100m
b) Henry's average speed over the race is; 5m/s.
According to the linear graph which describes the distance ran by Henry during the 100m race as a function of time.
a) Since the distance from start ran by Henry is plotted on the vertical axis, and the time is plotted on the horizontal axis;
To determine how long it took Henry to run 100m; The point corresponding to 100m is traced downward from the line of the graph and we find out that;
It takes Henry 20seconds to run 100m
b) Henry's average speed over the race is simply;
The slope of the distance-time graph.
Therefore,
- Average speed = (100-0)/(20-0)
Therefore, Henry's average speed over the race is; 5m/s.
