Density = Mass / Volume
Mass = 0.69kg
Volume of cylinder (coin) = Area X Height
Area of coin = (3.14)(0.03)^2
Height = Thickness = 0.003m
Volume of coin = (0.0003) X (3.14)(0.03)^2
Density = (Mass of coin) / (Volume of coin)
The cats resting points are D and E, because the line is flat. meaning no change in movement is occurring, so the cat is resting. And that means answer choice C, is correct!
Answer:
3.0 m
Explanation:
The height of the wave is just 1.5 m + 1.5 m which equals 3.0 m
Answer:
θ =28.07⁰
Explanation:
when van moves around an unbanked curve, horizontal component of normal force is equal to centripetal force
---(1)
There is no motion in vertical direction, so vertical component of normal force is balanced with weight of block i.e.
----(2)
divide (1) and (2)
v = 28 m/s
r = 150 m
g = 9.8m/
θ = 28.07⁰
