The given magnitude of forces of F₁ = F₄, F₂ = F₃, F₁ = 2·F₂, give the
forces that exert zero net torque on the disk as the options;
(B) F₂
(D) F₄
<h3>How can the net torque on the disk be calculated?</h3>
The given parameters are;
F₁ = F₄
F₂ = F₃
F₁ = 2·F₂
Therefore;
F₄ = 2·F₂
In vector form, we have;
Clockwise moment due to F₄, M₁ = 
Therefore;
Counterclockwise moment due to F₂ = 
Given that the clockwise moment due to F₄ = The counterclockwise moment due to F₂, we have;
Two forces that combine to exert zero net torque on the disk are;
F₂, and F₄
Which are the options; (B) F₂, and (D) F₄

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:(1) Pre-solar nebula
(2). Planet formation
Explanation:
Nebular hypothesis says that the Solar System formed from the gravitational collapse of a fragment of a giant molecular cloud.
One of the collapsing fragments called the pre-solar nebula formed what became the Solar System.
The planet can also be formed by accretion. Accretion is a process in which planets began as dust grains in orbit around the central protostar.
When the terrestrial planets were forming, they remained immersed in a disk of gas and dust.
Ummmm I don’t know this sorry
