Answer: acceleration = -10m/s^2
Explanation:
Use Fab 5 equation to solve for acceleration. (Use equation without d/distance because it is irrelevant for this particular question)
vi = 60m/s
vf = 0m/s because car comes to a stop
t = 6s
a = ?
d = irrelevant
Use a = vf-vi/t
Step by step solution:
a = vf - vi / t
a = 0 - 60 / 6
a = -60 / 6
a = -10m/s^2
Hope this helps! :)
Answer:
(a) τ=2.88 s, (b) q₀= 30.6μC and (c) t=1.434s
Explanation:
A RC circuit is an resistor(R)-capacitor(C) electric circuit.
(a) In a resistor-capacitor circuit, the time constant (τ) can be calculated by:
<em>where R: is the resistence and C: the capacitance of the capacitor</em>
(b) The maximum charge (q₀) is giving by:
<em>where ε: is the voltage across the capacitor</em>
(c) The time (t) that take the charge (q) to build up to 12 μC can be calculated from the next equation:
Have a nice day!
Answer:
The current flowing through the wire is 9 A.
Explanation:
Given;
quantity of charge passing through the wire, Q = 36 C
duration of the charge flow, t = 4 s
The current flowing through the wire is calculated as;
Q = It
I = Q / t
where;
I is the current flowing in the wire
I = 36/4
I = 9 A
Therefore, the current flowing through the wire is 9 A.
<span>The image formed by a plane mirror is always virtual (meaning that the light rays do not actually come from the image), upright, and of the same shape and size as the object it is reflecting. A virtual image is a copy of an object formed at the location from which the light rays appear to come.</span>
