Formula for Calculating Mass

The different varieties of ways to determine mass of an object

(M= p/v) / Mass = D/V (mass = density /volume

Mass= F/A (Mass= Force/Acceleration)

Around 62 million Americans are under warnings and winter weather alerts, as a bitterly cold storm moves across the U.S. — even bringing up to 19 inches of snow to Flagstaff and hail to Los Angeles.

The wintry mix hit hard in the northern U.S., closing schools, offices, even shutting down the Minnesota Legislature.

Behind Freddy there's Tropical storm Enala

02/21/2023

BREAKING NEWS:

CYCLONE Freddy TO HIT ZAMBIA AND NEIGHBOR COUNTRIES

A report from SADC-Climate Services Center sent to Zambian Post Media shows that in the coming days, an intense Tropical Cyclone (Freddy) is expected to make landfall in Zambia.

Including Mozambique, Zimbabwe and Malawi which will involve heavy rainfall with flash floods.

The situation may occasion a high risk of dangerous storm surge, flooding, and strong/damaging wind especially in locations on the storm's path in Zambia and indications are that the Southern Province will be most affected and some parts of Central and Eastern Provinces.

The UN’s World Food Programme (WFP) said more than 2.3 million people could be affected by cyclone Freddy.

Another 6.2 Magnitude Earthquake struck southern Turkey

02/17/2023

Tremours were felt in Jammu and Kashmir's Katra early morning on Friday, according to National Centre for Seismology.

An earthquake with a magnitude of 3.6 on the Richter Scale was recorded at 5.01 am today. The depth of the earthquake was recorded at 10 km.

"Earthquake of Magnitude:3.6, Occurred on 17-02-2023, 05:01:49 IST, Lat: 33.10 & Long: 75.97, Depth: 10 Km, Location: 97km E of Katra, Jammu and Kashmir," National Centre for Seismology said in a tweet.

On February nights, bright red Mars is in the constellation of Ta**us the Bull. Mars lies almost overhead near the Hyades and Pleiades star clusters, with Orion the Hunter finishing the scene. Also nearby are 2 bright red stars: Aldebaran, the Eye of the Bull, and Betelgeuse, the Hunter’s right shoulder. Mars sets after 3:00 a.m. local time at the beginning of the month, and it’s gone after 2:00 a.m. by month’s end.

The magnitude 7.8 and 7.5 earthquakes that struck southern Türkiye and western Syria on February 6, 2023, caused widespread destruction in both countries. https://go.nasa.gov/40HsemO

The initial earthquake emanated from a fault 18 kilometers (11 miles) below the land surface. The shallow depth meant the earthquake produced violent shaking that affected areas hundreds of kilometers from the epicenter. The first quake was followed by a 7.5 magnitude event about nine hours later, as well as hundreds of smaller aftershocks.

As news of the event spread, scientists at space agencies around the world—including NASA—began processing and analyzing satellite data relevant to the event.

“These were very large and powerful earthquakes that ruptured all the way up to the surface over a long series of fault segments,” said Eric Fielding, a geophysicist at NASA’s Jet Propulsion Laboratory. “This generated extremely strong shaking over a very large area that hit many cities and towns full of people. The rupture length and magnitude was similar to the 1906 earthquake that destroyed San Francisco.”

The preliminary damage proxy map shows parts of the cities of Türkoğlu, Kahramanmaraş, and Nurdaği. Dark red pixels represent areas likely to have severe damage to buildings, homes, and infrastructure or changes to the landscape, while orange and yellow areas are moderately or partially damaged. Each pixel measures about 30 meters across (about the size of a baseball infield).

The map is derived from data collected by JAXA(宇宙航空研究開発機構)'s PALSAR-2 radar instrument on the Advanced Land Observing Satellite-2 (ALOS-2) on February 8, 2023. The satellite carries a synthetic aperture radar, a sensor that sends pulses of microwaves toward Earth’s surface and listens for reflections of those waves to map the landscape, including buildings. By comparing the February 8 data to observations made by the same satellite before the earthquake (on April 7, 2021, and April 6, 2022), scientists tracked t

Scientists from NASA and other agencies are using satellites to map damage caused by the devastating earthquake.

Hours to impact! A newly discovered asteroid will hit Earth's atmosphere near northern France on February 13 around 03:00 UTC (that's around 9 pm CST). Fortunately, the asteroid, named Sar2667, is just 1-meter wide, which means it poses no danger to Earth. It should put on a good show for anyone nearby!

A 1-meter meteoroid (small ) has been detected and is expected to *safely* strike Earth's atmosphere over northern France between 3:50-4:03 CET.

A potentially 6 magnitude earthquake could come on 11 or 12 February

A lunar peak on 9-10 February may result in a strong shake, potentially reaching mid to higher 6 magnitude, most likely 11-12 February.

Did you know? Solar noon - aka midday - refers to that passing instant when the sun reaches its highest point for the day, midway between sunrise and sunset. Solar noon is not the same as noon on a clock. In fact, they rarely occur at the same time. Usually the sun reaches its highest point before or after noon on our clocks. And on February 11, for all locations on the globe, we have the latest solar noon of all. ☀️

Learn more about this year's latest solar noon: https://earthsky.org/astronomy-essentials/years-latest-solar-noon/

As this diagram depicts, solar noon isn’t necessarily a clock event, although clock noon and your solar noon do sometimes coincide. Solar noon is when the sun reaches its highest point for the day in your sky. This year’s latest solar noon occurs on February 11.

For you, if you’re time-conscious … February 11 marks the latest solar noon for all of 2023, and for the entire globe, by the clock. However, solar noon isn’t a clock event, even though our clocks and calendars measure its continual shift throughout the year. So what is it? It’s a natural ev...

Hawaiian monk seals need sandy beaches for resting and giving birth. In the Lalo atoll (known as the French Frigate Shoals in English), many of these sandbars and islets have been lost to sea level rise already. As part of the endangered seals' recovery plan, NOAA scientists are helping endangered Hawaiian monk seals find higher ground.

As key habitat goes underwater, NOAA is relocating some endangered Hawaiian monk seals to higher ground.
