The period of the spring, to move from its highest position to back to the highest position, is 1.2 seconds.What is the period of the spring?
The time period of the spring is used in spring mass system to find the oscillation of a system who perform simple harmonic motion.
The time period of the spring can be calculated with the following formula.
Here, (m) is the mass of the spring and (k) is the spring constant.
The time period for a mass on a spring to move from its highest position to its lowest position is 0.6 seconds.
For a full motion of oscillation, the spring should move from its highest position and return back to the highest potion.
Therefore, the time period of the spring is twice the time period for a mass on a spring to move from its highest position to its lowest position.
Hence, time period of spring is,
Hence, the period of the spring, to move from its highest position to back to the highest position, is 1.2 seconds.

What is the volume of 2400kg of gasoline (petrol) if the density of petrol is 0.7g/km3
Density = mass / volume
700 kg/m³ = 2400 kg / V
V ≈ 3.4 m³
Tara goes on a camel safari in Africa. She travels 5 km north, then 3 km east and then 1 km north again. What distance did she cover? What was her displacement?
The distance is a scalar quantity and displacement is a vector quantity which is the shortest distance between the initial and final position. The distance covered by the Tara will be 9 km, while the displacement will be 6.71 km.
Distance is defined as the distance covered only it is not concerned with any direction while the displacement is known as the shortest distance covered between the two points.How to find the distance and displacement with the help of direction?
Distance traveled by her will be,
Displacement is defined using the vector.
Dispacement in the north direction is (5j+j=6j)
Displacement in the east direction is (3i )
The resultant displacement of Tara can be calculated as,
Therefore, the displacement of Tara is 6.71 km.

Distance: 9 km
Displacement: 6,7 km
There are many people who believe that there is no difference between distance and displacement. The different between distance and displacement is that distance is the length of the journey taken to get there, displacement is a measurement of the space between two points.
In this case, distance would be equal to:
5 km + 3 km + 1 km= 9 km
However, displacement can be calculated using triangles:
3 km east total
6 km north total
using the formula:
r² = x² + y²
r² = (6)² + (3)²
r = 6,7 km

An object is attached to the lower end of a 100-coil spring that is hanging from the ceiling. The spring stretches by 0.170 m. The spring is then cut into two identical springs of 50 coils each. As the drawing shows, each spring is attached between the ceiling and the object. By how much does each spring stretch?
As we know by force balance
now we have
now we know that spring constant is inversely depends on the length of the spring
So when length of the spring is half then the spring constant is doubled
so we will have
now we have
