Answer:
30Ω
Explanation:
To calculate the equivalent resistance in the circuit, do the following:
Step 1:
10Ω and 20Ω are in series connection. Therefore their equivalent is: 10 + 20 = 30Ω
Step 2:
The equivalent resistance (30Ω) obtained from the above is in parallel connection with 30Ω resistance shown in the diagram above.
Therefore their equivalent is given by:
1/30 + 1/30 = 2/30 = 1/15.
Now invert to obtain the equivalent
Therefore, the equivalent is 15Ω
Step 3:
Determination of the overall equivalent of the resistance of the circuit.
The new equivalent resistance 15Ω obtained above is in series connection with 15Ω resistance in the diagram above.
Therefore their equivalent is given by:
15Ω + 15Ω = 30Ω
Therefore, the equivalent resistance in the circuit is 30Ω
Answer:
W ’= 21.78 kg
Explanation:
The expression for weight is
W = m g
let's look for the acceleration of gravity with the universal law of gravitation
F = G m M / r2
F = m (G M / r2)
without comparing the two equations
g’= G M / r2
in that case M = 2 Mo and r = 3 ro
where mo and ro are the mass and radius of the earth
we substitute
g ’= G 2Mo / (3r₀) 2
G ’= 2/9 G Mo / r₀²
g ’= 2/9 g
the weight of the body on this planet is
W ’= m g’
W ’= m 2/9 g
let's calculate
W ’= 2/9 10 9.8
W ’= 21.78 kg
Answer:
9.801 m/s²
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity = 39 ft/s
s = Displacement = 720 cm = 7.2 m
a = Acceleration
Converting to m/s
Equation of motion
Acceleration of the ball is 9.801 m/s²
Answer:
What is the average translational kinetic energy of molecules in an ideal gas at 37°C? The average translational energy of a molecule is given by the equipartition theorem as, E = 3kT 2 where k is the Boltzmann constant and T is the absolute temperature.
