Answer:
a = 156.14 m/s^2
Explanation:
Using the laws of newton:
∑F = ma
where ∑F is the sumatory of forces, m the mass and a the aceleration.
so:
F - = ma
where F is the force from the hockey stick and is the force of friction.
Replacing values, we get:
(30.2N) - (3.5N)= (0.171kg)a
Finally, solving for a:
a = 156.14 m/s^2
This path is called a circuit. Batteries<span> have three parts, an anode (-), a cathode (+), and the electrolyte. ... The chemical reactions in the </span>battery<span> causes a build up of electrons at the anode. This results in an electrical difference between the anode and the cathode.</span>
Answer:
t = 0.731s
Explanation:
In order to calculate the time that the capacitor takes to have a voltage of 70V, you use the following formula:
(1)
V: final voltage across the capacitor = 70V
Vo: initial voltage across the capacitor = 100V
R: resistance of the resistor in the circuit = 1kΩ = 1*10^3Ω
C: capacitance of the capacitor = 2mF = 2*10^-3F
t: time
You use properties of logarithms to solve the equation (1) for t:
Next, you replace the values of the parameters:
The capacitor takes 0.731s to reache a voltage of 70V
