The formula for getting the density of an object is
density = mass/volume = ρ = m/v
mass =42 kg
volume = 22m3
we will work on the equation directly because they are already in there SI units
density = 42 kg/22m3
density = 1.9090909090909
which if rounded can become 1.9 kg/m3
ans = the object's density is 1.9090909090909 kg/m3 or 1.9 kg/m3
The answer is true. brainly?
Answer:
Explanation:
a) ωp = 2π radians / 1.7 s = <u>3.7 rad/s</u>
b) ωs = 3.7 rad/s(9.5 cm / 4.5 cm) = 7.8 rad/s
v = (ωs)R = 7.8(65) = 507 cm/s or <u>5.1 m/s</u>
c) ωs = 3.5 m/s / 0.65 m = 5.38 rad/s
ωp = 5.38(4.5 cm / 9.5 cm) = 2.55 rad/s
t = θ/ω = 2π / 2.55 = 2.463... <u>2.5 s</u>
