Answer:
The resistivity of the wire is 
Explanation:
We have,
Length of a wire is 40 cm or 0.4 m
Diameter of a wire is 0.60 mm
Radius is 0.3 mm or 0.0003 m
Resistance of a wire is 1.5 ohm
Now we need to find the resistivity of the material of which it is made. The resistance of a wire in terms of its resistance, length and area is given by :
= resistivity
So, the resistivity of the wire is .
<span>We know that an object in moving with acceleration follow the rule according that
the distance covered will be : d = Vi*t + 1/2*a*t^2
where d is distance, Vi is initial speed, and a is acceleration
Then after 1 km which is 1000 metres we have:
1000 = Vi *71.2 + 1/2*0.0499*(71.2)^2
Vi = (1000-1/2*0.0499*(71.2)^2)/71.2 = 1000/71.2 - 1/2*0.0499*71.2 = 12.27 m/s
Then the car was going at 12.27 m/s when started to accelerate.</span>
The answer to this question would be:C. 22mf
In this question, there are two capacitors that connected in parallel. The formula to count the capacitor is the opposite of the formula used for the resistor. If constructed in series, the capacitor will have reduced capacitance. For parallel condition the equation would be:
Ctotal= C1+C2
C total= 2 mf+ 20mf= 22mf
