Germanium is not found as the free element in nature. Germanium is found in germanite, argyrodite, and some zinc ores. It is also present in coal and its presence in coal insures reserves for many years. so it is man made

True or false: objects fall toward earth at a rate of 9.8 m/s because of centripetal force.
Citrus2011 [14]
Sadly, no. The statement kind of has some appropriate words in it, but it's badly corrupted. Objects don't fall to Earth at a rate of 9.8 m/s, and the force that accelerates them downward is not a centripetal one.

a ball is thrown straight up it passes a 2.00 m high window 7.5 meters off the ground on its path up it takes 1.3 s to go past t
Svet_ta [14]
Let's say the velocity at the bottom of the window was "v."
s = v*t + ½at²
2 m = v * 1.3s - 4.9m/s² * (1.3s)² = v * 1.3s - 8.3 m
v = 10.3m / 1.3s = 7.9 m/s

Then the initial speed was
V = √(v² + 2as) = √(7.9m/s² + 2 * 9.8m/s² * 7.5m) = 14 m/s ◄ initial velocity
(after rounding to 2 digits from 14.5 m/s).

A torsion pendulum consists of an irregularly-shaped object of mass 20.0 kg suspended vertically by a wire of torsion constant 0
netineya [11]

Answer:

Rotational inertia of the object is, I=0.023\ kg-m^2

Explanation:

Given that,

Mass of the object, m = 20 kg

Torsion constant of the wire, K = 0.85 N-m

Number of cycles, n = 69

Time, t = 66 s

To find,

The rotational inertia of the object.

Solution,

There exists a relationship between the moment of inertia, time period and the torsion constant of the spring is given by :

T=2\pi\sqrt{\dfrac{I}{K}}

Here I is the moment of inertia

T is the time period, and it is equal to the number of cycles per unit time

I=\dfrac{T^2K}{4\pi ^2}

I=\dfrac{(69/66)^2\times 0.85}{4\pi ^2}

I=0.023\ kg-m^2

So, the rotational inertia of the object is 0.023\ kg-m^2.
