An infant's toy has a 120 g wooden animal hanging from a spring. If pulled down gently, the animal oscillates up and down with a
Morgarella [4.7K]

Answer:

0.37 m

Explanation:

The angular frequency, ω, of a loaded spring is related to the period, T,  by

\omega = \dfrac{2\pi}{T}

The maximum velocity of the oscillation occurs at the equilibrium point and is given by

v = \omega A

A is the amplitude or maximum displacement from the equilibrium.

v = \dfrac{2\pi A}{T}

From the the question, T = 0.58 and A = 25 cm = 0.25 m. Taking π as 3.142,

v = \dfrac{2\times3.142\times0.25\text{ m}}{0.58\text{ s}} = 2.71 \text{ m/s}

To determine the height we reached, we consider the beginning of the vertical motion as the equilibrium point with velocity, v. Since it is against gravity, acceleration of gravity is negative. At maximum height, the final velocity is 0 m/s. We use the equation

v_f^2 = v_i^2+2ah

v_f is the final velocity, v_i is the initial velocity (same as v above), a is acceleration of gravity and h is the height.

h = \dfrac{v_f^2 - v_i^2}{2a}

h = \dfrac{0^2 - 2.71^2}{2\times-9.81} = 0.37 \text{ m}

How did cyanobacteria affect early Earth’s biosphere? Select all that apply. Cyanobacteria allowed organisms that rely on oxygen
FrozenT [24]

Answer:

The correct statements would be

  • Cyanobacteria allowed organisms that rely on oxygen to evolve.
  • Cyanobacteria preceded the first photosynthetic organisms.
  • Cyanobacteria produced excess oxygen.

Cyanobacteria, also termed as blue-green algae are the prokaryotes which are able to perform photosynthesis.

They were the major contributors of oxygen in the atmosphere and thus helped the organisms that rely on oxygen to evolve.

By the process of endosymbiosis, they lead to the origin of plants. The chloroplasts present in green plants is considered as the cyanobacteria living in the plant cell. It helps in photosynthesis and in return plants cell provides shelter to it.

It is believed that the oxygen released from early cyanobacteria reacted with dissolved iron ions to form iron oxide.
