A cancer or cancerous tumour on the skin as a result of extensive exposure to UV rays.

nekit [7.7K]

Answer:

Almost all skin cancers (approximately 99% of non-melanoma skin cancers and 95% of melanoma) are caused by too much UV radiation from the sun or other sources such as solaria (solarium, sunbeds, and sun lamps).

Explanation:

Skin cancer develops in the cells in the epidermis – the top or outer layer of the skin. UV radiation is made up of UVA and UVB rays which are able to penetrate the skin and cause permanent damage to the cells below:

UVA penetrates deeply into the skin (the dermis) causing genetic damage to cells, photo-ageing (wrinkling, blotchiness etc) and immune-suppression.

UVB penetrates into the epidermis (top layer of the skin) causing damage to the cells. UVB is responsible for sunburn – a significant risk factor for skin cancer, especially melanoma.

If the body is unable to repair this damage the cell can begin to divide and grow in an uncontrolled way. This growth can eventually form a tumor.

UVA and UVB both contribute to sunburn, skin ageing, eye damage and melanoma and other skin cancers.

A remote ranch has a cylindrical water storage tank. It has a vertical central axis, a diameter of 24 ft, the sides are 5 ft hig

Effectus [21]

Answer:

Explanation:

From the given information:

The diameter of the pool = 24 ft

The radius will be = 24 ft/2 = 12 ft

The volume of water V = πr²(Δx)

V = π× 12²×(Δx)

V = 144π(Δx)

Le's assume water weighs 62.5 lb/ft³;

Then:

the Force (F) will be:

= 144π(Δx) * 62.5

= 9000πΔx lb

Also, the side of cylindrical water = 5 ft while its depth = 4ft

As such, each slide of water d = 5 - x, and the region is between 0 and 4.

∴

The required work is:

$W = \int^4_0 (5-x) 9000 \ \pi dx \\ \\ W = 9000 \int^4_0 (5-x) \ dx \\ \\ W = 9000 \pi \Big [5x - \dfrac{x^2}{2} \Big]^4_0 \\ \\ W = 9000 \pi \Big [5*4- \dfrac{4^2}{2} \Big] \\ \\ W = 9000 \pi \Big [20-8 \Big] \\ \\ W = 9000 \pi \Big [12 \Big] \\ \\ W = 9000 \pi (12) \\ \\ \mathbf{W = 108000 \pi \ ft.lb}$
