Answer:
a
Explanation:
If its not right choose D
Answer:
- maintain its state of motion
- Keep its velocity constant (either at zero or non-zero value)
Your answer are pretty much correct.
1.) Which car has the larger impulse imparted to it by the applied force? Explain your answer. yes it is the Town’s Car because <span>he Lincoln Car has twice the mass of the Civic, it has more impulse.
2,) momentum = mv, your answer is still correct. t</span><span>he Lincoln Car has twice the mass of the Civic, it has more impulse.
3. w = fd since they applied the same force, so it is more logical that the lighter car would travel further so the car with greater work done is the honda civic</span>
KE= 0.5(mv^2)
All of your variables are in standard units so you're good to just plug in
.5(30kg*(3.4m/s)^2)= 173.4 J
Complete question:
Resistor is made of a very thin metal wire that is 3.2 mm long, with a diameter of 0.4 mm. What is the electric field inside this metal resistor? If the potential difference due to electric field between the two ends of the resistor is 10 V.
Answer:
The electric field inside this metal resistor is 3125 V/m
Explanation:
Given;
length of the wire, L = 3.2 mm = 3.2 x 10⁻³ m
diameter of the wire, d = 0.4 mm = 0.4 x 10⁻³ m
the potential difference due to electric field between the two ends of the resistor, V = 10 V
The electric field inside this metal resistor is given by;
ΔV = EL
where;
ΔV is change in electric potential
E = ΔV / L
E = 10 / (3.2 x 10⁻³ )
E = 3125 V/m
Therefore, the electric field inside this metal resistor is 3125 V/m
