Answer:
b ≈ 64 Kg/s
Explanation:
Given
Fd = −bv
m = 2.5 kg
y = 6.0 cm = 0.06 m
g = 9.81 m/s²
The object in the pan comes to rest in the minimum time without overshoot. this means that damping is critical (b² = 4*k*m).
m is given and we find k from the equilibrium extension of 6.0 cm (0.06 m):
∑Fy = 0 (↑)
k*y - W = 0 ⇒ k*y - m*g = 0 ⇒ k = m*g / y
⇒ k = (2.5 kg)*(9.81 m/s²) / (0.06 m)
⇒ k = 408.75 N/m
Hence, if
b² = 4*k*m ⇒ b = √(4*k*m) = 2*√(k*m)
⇒ b = 2*√(k*m) = 2*√(408.75 N/m*2.5 kg)
⇒ b = 63.9335 Kg/s ≈ 64 Kg/s
Heat Flow. The heat is transferred from the hotter object to the cooler object. The heat transfer happens until they come to a thermal equailibrium and the temperatures are the same. Heat usually always flows froma object towards the cool object.
What do you mean??
Of-course, they have different number of values but range has to be in rules of function, it can't deviate from that
Answer:
45.83MPH
Explanation:
Let's use equivalent ratio.
275 miles = 6 hours
6 / 6
45.83 miles = 1 hour
