Answer:
Resistance = 3.35*
Ω
Explanation:
Since resistance R = ρ
whereas 
resistivity is given for two ends. At the left end resistivity is 
whereas x at the left end will be 0 as distance is zero. Thus
At the right end x will be equal to the length of the rod, so 
Thus resistance will be R = ρ
where A = π 
so,
Hi!
Mechanical advantage is defined as the<em> ratio of force produced by an object to the force that is applied to it.</em>
In our case, this would be the ratio of the force applied by the claw hammer on the nail to the force Joel applies to the claw hammer, which is
160:40 or 4:1
So the mechanical advantage of the hammer is four.
Hope this helps!
1) 15 / 12 = 1.25 ratio
2) to increase acceleration 1.25 times (with same F, or same engine) you have to lower mass 1.25 times
3) 1515/1.25 = 1212 kg
choose A
Answer:
1.99×10^-4coulombs
Explanation:
The charge (Q) across the resistor the directly proportional to the voltage (V) where capacitance of the capacitor(C) is the proportionality constant. Mathematically, Q = CV
If V is the voltage across the resistor, V = IR (according to ohm's law) where I is the current in the resistor and R is the resistance.
We need to calculate the voltage on the resistor first when 0.18A current is passed through it.
V = 0.18 × 185
V = 33.3Volts
The charge Q on the resistor will be;
Q = CV
Were C = 6.00 μF, V = 33.3
Q= 6×10^-6 ×33.3
Q = 0.0001998
Q= 1.99×10^-4Coulombs
