Acceleration units are in m/s^2 , so you take 25.5 m/s divided by 5.75s. Acceleration is the rate of change of velocity :)
follow me on instagram : imrajsingh :):) thanks
Answer:
0.01 m/s^2.
Explanation:
The formula for acceleration is Δ velocity/ Δ time or change in velocity/change in time. We can see find the change in velocity by subtracting v0 (initial velocity) from v (current velocity). v - v0 = 80.3 m/s - 80.1 m/s = 0.2 m/s. The change in time is already given, 20 seconds, so all you have to do is divide 0.2 m/s by 20 seconds to get 0.01 m/s^2.
Answer:
the electric field is proportional to the voltage divided by the separation of the plates,
Explanation:
This parallel plate configuration is widely used, as it creates a uniform electric field between the plates. Where the potential and field differences are related by
DV = E d
That is, the electric field is proportional to the voltage divided by the separation of the plates, in general all these configurations are called capacitors
Answer:
240 Ω
Explanation:
Resistance: This can be defined as the opposition to the flow of current in an electric field. The S.I unit of resistance is ohms (Ω).
The expression for resistance power and voltage is give as,
P = V²/R.......................... Equation 1
Where P = Power, V = Voltage, R = Resistance
Making R the subject of the equation,
R = V²/P.................... Equation 2
Given: V = 120 V, P = 60 W.
Substitute into equation 2
R = 120²/60
R = 240 Ω
Hence the resistance of the bulb = 240 Ω
