The torque on the lever, with a 15 N force applied perpendicular at 2.0 m from the pivot point, is 30 N·m.
The torque on a lever is calculated by the formula T = rF sin θ, where T is torque, r is the distance from the pivot point to the point where the force is applied (lever arm), F is the force applied, and θ is the angle between the lever arm and the direction of the force. In this case, the force is applied at 90° to the lever arm, so the sin θ part of the formula is equal to 1. Therefore, the torque can be calculated by multiplying the force by the lever arm distance. With a force of 15 N applied perpendicular to the lever arm at a distance of 2.0 m from the pivot point, the torque on the lever would be 30 N·m (15 N x 2.0 m).

In the periodic table, the group number of astatine is 17 while that of tellurium is 16, hence the size of astatine is larger as compared to tellurium as it has one more shell present in it's atom.
Periodic table is a tabular arrangement of elements in the form of a table. In the periodic table, elements are arranged according to the modern periodic law which states that the properties of elements are a periodic function of their atomic numbers.
It is called as periodic because properties repeat after regular intervals of atomic numbers . It is a tabular arrangement consisting of seven horizontal rows called periods and eighteen vertical columns called groups.
Elements present in the same group have same number of valence electrons and hence have similar properties while elements present in the same period show gradual variation in properties due to addition of one electron for each successive element in a period.

formation of these mountains?
O The crust is compressed
O The crust does not spread apart
The center block is forced upward.
The hanging walls from the two parallel faults slip down
The Formation of these mountains will be caused by
Options B, C, and D is correct.
Generally, a mountain is simply defined as a body that rises dramatically above its surroundings and is distinguished by steep slopes.
In conclusion, Mountains are formed from the formation of rocks over years in an Environment.

Answer:
d.
Explanation:
B. water.
C. manganese.
D. petroleum.
Answer:
Option-B (water) is the correct answer.
Explanation:
Gas hydrates are made up of Solid-Ice water and a natural gas like Methane gas trapped in the lattice of ice water. Gas hydrates are mainly found deep down in the sea where the atmospheric pressure is greater than 1 atm.
Generally Gas hydrates have two main applications.
a) It stabilizes the sea floor other wise its melting will cause land sliding in sea floor.
b) Secondly, it traps a green house gases like Methane, if released these gases could produce Climate changes.
Answer:
B) water
Explanation:
Gas hydrates are essentially crystalline solid cage like structures in which small molecules are trapped in a network of frozen water molecules. The trapped gas molecules are usually methane which is a natural gas.
These methane hydrates are formed when methane and water combine under high pressure conditions usually prevalent in the ocean floors. Gas hydrates are also regarded as a powerful candidates for the production of cleaner energy.
