Answer:
8.59 rad/s
Explanation:
Given that:
A thin uniform cylindrical turntable radius = 2.7 m
with a mass (M) = 22 kg
initial angular speed (ω₁) = 12 rad/s
Mass of the clump of the clay (m) = 11 kg
Diameter (d) from the point of rotation = 1.7 m
We are to find the final angular velocity (ω₂) ,To do that; we apply the conservation of annular momentum; which is as follows:
L₁ = L₂
l₁ω₁ = l₂ω₂
( 0.5 × M × r²) × ω₁ = (0.5 × M × r² + md²) ω₂
Making ω₂ the subject of the formula ; we have:
Hence, the angular speed of the clay and turntable = 8.59 rad/s
Load is the weight exerted by an object to be moved or lifted
Answer:
Electric and magnetic fields:
Maxwell's equations tell us that
a changing magnetic field creates a changing electric field and
a changing electric field creates a changing magnetic field
Answer:
According to Japanese legend, Himiko was the daughter of the emperor Suinin (fl. 1st century bc–1st century ad), who gave her custody of the sacred mirror, symbol of the sun goddess. In 5 bc she supposedly enshrined the mirror at Ise, a city of present Mie Prefecture.
