This ratio (Fnet/m) is sometimes called the gravitational field strength
and is expressed as 9.8 N/kg ⇒ answer D
Explanation:
The gravitational field strength at a point is:
- The gravitational force exerted per unit mass placed at that point.
- This means that the gravitational field strength, g is equal to the force experienced by a mass of 1 kg in that gravitational field
- Gravitational field strength = Weight/mass
- Its unit is Newton per kilogram
- Gravitational field strength ≈ 9.8 N/kg
From the notes above
The ratio
= Gravitational field strength (g)
The answer is:
This ratio (Fnet/m) is sometimes called the gravitational field
strength and is expressed as 9.8 N/kg

Answer:
6 climate regions are Mediterranean, Polar, Tropical, Temperate, Arid and Tundra.
Explanation:
There are six main climate regions in the world. These regions distinguished from one another on the basis of climate that exists there. Above mentioned climates are described shortly as follows:
Mediterranean: This region is the region surrounding the Mediterranean sea, Southern California and Southern America. The climate in this region is hot and dry in summer whereas mild winters are there in this region.
Polar: This region is on the South Pole, near the side of Greenland. The climate in this region is very cold and chilled.
Tropical: This region consists of jungles of South America, Africa, some parts of Asia and the islands of Pacific. The climate of this region is Hot. Due to heavy rainfalls in this area, the area is also wet.
Temperate: North America, Europe and Northern Asia is included in this region. The climate is mild hot in summers and cold in winters.
Arid: This region consists of deserts of Africa, Asia, US and Australia. The climate is very hot throughout the year.
Tundra: This region consists of the mountain tops of America, Asia and Greenland. The climate is extremely cold in such regions throughout the year.

Answer:
the doppler technique
Explanation:
The doppler technique was an indirect method for finding extrasolar planets and brown dwarfs from radial-velocity measurements using observation of Doppler shifts in the spectrum of the planet's parent star.
