Explanation: The first one
Source: it literally has fusion in the name
Answer:
the voltage across each resistor is one third of the battery voltage
Explanation:
In a series circuit, the current is constant throughout the circuit, so the battery voltage is equal to the sum of the voltage drop in each part of the series circuit.
V = i (R₁ + R₂ + R₃)
in the exercise indicate that all resistance has the same value
R₀ = R₁ = R₂ = R₃
V = i 3 R₀
V
= 3 V₀
V₀ = i R₀
V₀= V / 3
the voltage across each resistor is one third of the battery voltage
Answer:
y = 0m
y0 = 166m
v0y = 0 m/s
g = 9.8 m/s^2
t = ?
Solve for t:
y = y0 + v0y*t - (0.5)gt^2
0 = 166 - (0.5)(9.8)t^2
t = 5.82 s
Now, using time, we can solve for the range using the equation:
x = vx(t)
x = (40)(5.82)
x = 232.8 m
The impact horizontal component of velocity will be 40 m/s as velocity in terms of x is always constant. To find the impact vertical component of velocity, we use the equation:
v = v0y - gt
v = 0 - (9.8)(5.82)
v = -57.04 m/s
Explanation:
Light is clearly affected by gravity, just think about a black hole, but light supposedly has no mass and gravity only affects objects with mass. On the other hand, if light does have mass then doesn't mass become infinitely larger the closer to the speed of light an object travels.
R = 11 ohms
Explanation:
Given parameters:
Power of the electric toaster = 1100W
Voltage = 110V
Unknown:
Resistance, R of the heating coli = ?
Solution:
Electric power is given as:
Electric power = IV
where:
I is the current
V is the voltage
According to Ohm's law, V = IR
where R is the resistance. If we make current the subject of the formula and substitute, it gives:
Power = ![\frac{[tex]V^{2}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Btex%5DV%5E%7B2%7D)
}{R}[/tex]
Power = ![\frac{[tex]110^{2}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Btex%5D110%5E%7B2%7D)
}{R}[/tex]
R = ![\frac{Power }{[tex]110^{2}](https://tex.z-dn.net/?f=%5Cfrac%7BPower%20%7D%7B%5Btex%5D110%5E%7B2%7D)
}[/tex] = ![\frac{1100 }{[tex]110^{2}](https://tex.z-dn.net/?f=%5Cfrac%7B1100%20%7D%7B%5Btex%5D110%5E%7B2%7D)
}[/tex]
R = 11 ohms
