Subatomic particles cannot be broken down any further
Answer:
1.55 h
Explanation:
Let the time to spend over dinner be t.
Since I need to spend 10.8 h for the whole trip, then I have 10.8 - t hours left to drive.
Speed = distance/time


The distance is 549 and maximum speed is 65 mi/h.



The magnetic field lines
around a long wire which
carries an electric current
form concentric circles
around the wire. The
direction of the
magnetic field is
perpendicular to the wire
and is in the direction
the fingers of
your right hand
would curl if you
wrapped them
around the wire
with your
thumb in the direction
of the current.
hope it helps you

Answer:</h2>
(a) 10.00V
(b) 0.5V
<h2>
Explanation:</h2>
(a) The power(P) supplied by a resistor of resistance (R) when a voltage(V) is passed across is given by;
P = V² / R ------------------(i)
From the question;
P = 5.00W
R = 20.00Ω
Substitute these values into equation (i) as follows;
5.00 = V² / 20.00
V² = 5.00 x 20.00
V² = 100.00
V = 
Solve for V;
V = 10.00V
Therefore, the maximum voltage that can be applied without harming the resistor is 10.00V
(b) By Ohm's law the current (I) flowing through a resistor of resistance (R) when a voltage (V) is applied is given by;
V = I x R
=> I = V / R ----------------(ii)
Substitute the values of V and R into equation (ii) as follows;
I = 10.00 / 20.00
I = 0.5A
Therefore, the current through the resistor is 0.5A
