Answer: 5.72 x 10-3Ω
Explanation:
Hi, to answer this question, first we have to calculate the cross sectional area of the cable:
Diameter (D)=6.07 mm
Since: 1000mm = 1m
6.07mm/ 1000mm/m = 0.00607 meters
Area of a circle : π (d/2)^2
A = π (0.00607/2)^2= 0.000028937 m2
Resistance formula:
Resistance (R) = P(resistivity) L (length)÷A (cross sectional area )
Replacing with the values given:
R = (2.82x10-8 x 5.87) / 0.000028937
R = 5.72 x 10-3Ω
Feel free to ask for more if needed or if you did not understand something.
distance traveled by a uniformly accelerated bike is given as
here we know that
now we will have from above equation
so it will cover the total distance of 300 m
Answer:
A) how your body uses oxygen
Answer: The velocity is 21.5m/s
Explanation:
Let's call:
M1 and V1 as the mass and velocity of the falcon:
M1 = 1.45kg
V1 = 26.5m/s
M2 and V2 as the mass and velocity of the dove:
M2 = 0.415kg
V2 = 4.35m/s
Where both velocities are positive because both animals move in the same direction.
We can think that the interaction between both animals is a perfectly inelastic collision, because afther the interaction they move as one. Then, we have that the final velocity of both animals togheter is:
V = (V1*M1 + V2*M2)/(M1 + M2)
V = (1.45kg*26.5m/s + 0.415kg*4.35m/s)/(1.45kg + 0.415kg) = 21.5m/s
This is a divergent plate boundary because the two tectonic plates are colliding together.
