Answer:
The work done by the spring is 2.025 J
Explanation:
Given;
mass on the spring, m = 0.5 kg
spring constant, k = 5 N/m
extension of the spring, x = 0.9 m
The work done by the spring is calculated as;
Therefore, the work done by the spring is 2.025 J
Answer:
The trucks must have equal masses that is they must have same load.
Explanation:
Momentum refers to the product of the mass of the object and velocity.
As momentum has both magnitude and direction, it is a vector quantity.
In the given problem, it is given that after the collision, the trucks move at more than half the original speed of the moving truck. Therefore, the trucks must have equal masses that is they must have the same load.
Answer:
The correct order of answers are: insolation, temperature, pressure, masses and water.
Explanation:
Daily, seasonal, and latitudinal changes in solar insolation affect Earth's climate systems. Latitude, elevation, and contrasts between land and ocean masses influence temperature patterns across the globe. Atmospheric circulation cells create rather stable regions of alternating high and low air pressure across latitudes. Temperature and water can be easily moved from place to place by air masses. Water movement via the hydrologic cycle strongly influences Earth's diverse climates.
Answer:
The theory of relativity usually encompasses two interrelated theories by Albert Einstein: special relativity and general relativity, proposed and published in 1905 and 1915, respectively. Special relativity applies to all physical phenomena in the absence of gravity.
