4 0

Answer:

Three advantages of Reflecting Telescope over refracting Telescope:

1. there is no chromatic aberration in the Reflecting Telescope being mirror as an objective, while Refracting Telescope can suffer chromatic aberration being using lenses.

2. image of Reflecting Telescope is brighter due to large, polished curved mirrors than Refracting Telescope

3. Reflecting Telescope is compact and portable in size than Refracting Telescope.

two identical, thin rods, each with mass mm and length ll, are joined at right angles to form an l-shaped object. this object is
Allushta [10]

The length of time that an action or state persists. The given L-shaped object made of two rods oscillates at a frequency of 2π√√2L/3g.

The rod weighs m grams.

The length of a single rod is L.

If it is connecting at, as indicated by the query, then the moment of inertia of the combined system follows.

mL²/3+3L²/3=2mL²/3

Here, I denotes the rod's moment of inertia, d denotes the separation of the center of gravity from the fixed point, and T denotes the length of time the L-shaped object oscillates.

Length of pendulam

Lcos45=L*1/√2=L/√2

Caluclate the time period

T=2π√I/mgl

=2π√2*mL²*√2/3*2mgl

oscillates at a frequency = 2π√√2L/3g
