I think the correct answer would be to electrolyze water (run an electric current through it) to decompose it into hydrogen and oxygen. Assuming 100% efficiency, it is said that it needs about 40kWh per kilogram of water to fully decompose it.

An object is launched with an initial speed of 30 m/s at an angle of 60° above the horizontal . What is the maximum height reach
matrenka [14]

Answer:

H = 34.43 m

Explanation:

Given that,

Initial speed of the object, u = 30 m/s

The angle of projection, \theta=60^{\circ}

We need to find the maximum height reached by the object. Let it is H. Using the formula for maximum height reached by the projectile.

H=\dfrac{u^2\sin^2\theta}{2g}\\\\H=\dfrac{(30)^2\times \sin^2(60)}{2\times 9.8}\\\\H=34.43\ m

So, the maximum height reached by the object is 34.43 m.

A client is undergoing diagnostics for an alteration in thyroid function. What physiologic function is affected by altered thyro
xxTIMURxx [149]

Answer:

The thyroid is a butterfly-shaped gland that sits low on the front of the neck.It plays a major role in the metabolism, growth and development of the human body

Explanation:

The physiologic function affected by altered thyroid function are:

1. It is likely that all cells in the body are targets for thyroid hormones

2. It stimulates diverse metabolic activities most tissues, leading to an increase in basal metabolic rate

3. Thyroid hormones are clearly necessary for normal growth

Thyroid hormones increases heart rate, cardiac contractility and cardiac output. They also promote vasodilation (widening of blood vessels), which leads to enhanced blood flow to many organs. Central nervous system: Both decreased and increased concentrations of thyroid hormones lead to alterations in mental state.

There do not seem to be organs and tissues that are not affected by thyroid hormones
