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
Answer:
0.7m/s^2
Explanation:
acceleration=(final-initial velocity)/time
x=(14-0)/20
x=14/20
x=0.7
C) No valid conclusion is suggested by these observations.
Explanation:
From the experiment, no valid conclusion can be drawn from the observations.
The tests are simply based on heat loss by a material.
- In conduction, heat is lost by contact between materials in which heat flows from one to another.
- Convection is a form of heat loss in which heat flows by density in fluids
- The test carried out does not provide proof and comparison between heat loss by conduction and convection.
