Two forces while acting on a particle in opposite direc- tions, have the resultant of ION. If they act at right angles to each other, the resultant is found to be 50 N. Find the two forces

Answer»

Again when the forces are acting at right angles we have : SQUARED root(X^2 + Y^2 +2*X*Y*COS90) =50 NEWTON. THEREFORE, X=(10+Y)=10+30=40 Newton. HENCE the two forces are 30 and 40 Newton

Earthquakes: Movement of the Earth’s CrustEarthquakes are the shaking and moving of the ground when energy is released in waves. Thesewaves are called seismic waves. These waves are similar to ocean waves, which move throughwater. Seismic waves, however, move through the ground. Most earthquakes are caused by themovement of large sections of the Earth’s CRUST, called plates. The place where two plates meetis called a fault. Faults look like large cracks in the ground. If the two plates move in DIFFERENTDIRECTIONS, they build up energy at the fault line. When enough energy builds up, the stress on thefault becomes too great and it ruptures. This releases the energy and theground starts to shake.Earthquakes can also be caused by other natural events, such as landslides and volcanoes. Man-made earthquakes happen because of nuclear testing and mining explosions. The first movementof an earthquake, called the main shock, is often followed by smaller ground trembles, calledaftershocks. These aftershocks are the plates settling into their new position. Aftershocks cancontinue for days after the main shock. There are an estimated 500,000 earthquakes around theworld each year. Most are so mild they are only recorded on scientific instruments. Only about100,000 can be felt by humans. Of these, only about 19 a year CAUSE major damage.Major earthquakes in populated areas can cause huge destruction. Buildings collapse, roads andbridges buckle and crack, and electrical and gas lines break and cause fires. If the earthquakehappens in the ocean, it makes a series of huge ocean waves called a tsunami. The tsunamitravels until it finally reaches land, where it causes large flooding. Scientists are searching forways to predict earthquakes. They study the historical patterns of earthquakes and monitor themovement of the plates with seismic EQUIPMENT. While they cannot predict an exact date of afuture earthquake, they have a better UNDERSTANDING of when earthquakes are more likely tohappen. List out different Adjectives from the passage and name them.
