Answer:
-29.4 m/s
Explanation:
Given:
v₀ = 0 m/s
t = 3 s
a = -9.8 m/s²
Find: v
v = at + v₀
v = (-9.8 m/s²) (3 s) + (0 m/s)
v = -29.4 m/s
The volume of the cylindrical can is given by:
V = πr²h
V = volume, r = base radius, h = height
Differentiate both sides of the equation with respect to time t. The radius r doesn't change over time, so we treat it as a constant:
dV/dt = πr²(dh/dt)
Given values:
dV/dt = -527in³/min
r = 8in
Plug in and solve for dh/dt:
-527 = π(8)²(dh/dt)
dh/dt = -2.62in/min
The height of the water is decreasing at a rate of 2.62in/min
Answer:
The Chinese government wish to keep the currency undervalued because: A weaker exchange rate makes exports more competitive and increases demand for Chinese exports. Chinese economic growth is dependent on exports, so the value of the currency plays a key role in boosting growth.
