Why is the mass of a person at the equator approximately 1% less than at the pole?

Since the Earth rotates around its axis, a centrifugal force is manifested on its surface, Directed from the center of the Earth (upwards). At the equator, where the linear speed of the surface is greatest (1670 km/h), it is subtracted from the weight (the force acting on the support), and it is absent at the poles.

What was the largest eruption in history?

Answering this question, we must emphasize that we are talking about a known history, that is, one about which there is information in the sources. In prehistoric times and during the formation of the Earth's surface, there must have been eruptions and earthquakes of terrible force. But, as far as we know from sources, the largest eruption was in 1883 on the volcanic island of Krakatoa in the Dutch Indies (Republic of Indonesia). The most powerful series of volcanic explosions occurred on August 27 of that year.

Let's see what some of the consequences of this incredible explosion were. First of all, the entire northern part of the island and its lower parts simply disappeared! Before the explosion, the area of the island was 18 square miles, and its height above sea level ranged from 91 to 4250 meters. After the explosion, a hole was formed at the bottom of the ocean, which was 300 meters below the water level! Columns of stones, dust and ash rose up to 17 miles into the air, and when all this began to dissipate, everything within a radius of 150 miles was plunged into darkness in broad daylight! The sound of these volcanic explosions was heard over a vast area. It was indeed the longest distance ever traveled by sound - 3000 miles!

The most severe destruction was probably associated with the waves in the ocean that rose as a result of this monstrous explosion. The largest wave reached a height of 15 meters, it demolished entire villages and became the culprit in the death of 36 people. In addition, these waves traveled enormous distances and perhaps even reached the English Channel, located 000 miles away. By the way, the Krakatau volcano came to life even in 11000, but, fortunately, this time there was no big volcanic explosion.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

Huawei 5G Mobile WiFi Pro Router 25.10.2019

Huawei has unveiled Huawei 5G Mobile WiFi, a mobile WiFi router with a built-in 5G modem that can also act as a power bank for other mobile devices.

Externally, Huawei 5G Mobile WiFi resembles a regular portable battery in a rectangular case. At the same time, the design of the router echoes the Huawei Mate 30 RS Porsche Design premium smartphone: here the front panel is leather-like, diluted with a vertical strip of black glass in the center.

Huawei 5G Mobile WiFi equipment includes the Balong 5 5000G modem with support for non-standalone (NSA) and standalone (Standalone, SA) networks, which we detailed here. Huawei claims speeds of up to 1,56 Gbps (connection) and up to 867 Mbps (connection).

Huawei 5G Mobile WiFi will be offered in two versions 5G Mobile WiFi and 5G Mobile WiFi Pro, differing in built-in battery capacity and charging speeds. The younger 5G Mobile WiFi is equipped with a built-in 4000 mAh battery, and the older 5G Mobile WiFi Pro has an element twice as large - 8000 mAh. In addition, support for triple fast charging is announced for the older model: the battery itself supports Huawei's proprietary 40-watt charging technology using a charger of the appropriate power and at the same time can quickly charge other mobile devices with 22,5 W over the wire and 18 W over the air (reverse wireless charger).

Another feature of Huawei 5G Mobile WiFi is a small informative display at the top, where a QR code can be displayed to quickly connect to the network.
