It means you need to put a lot of heat into it to raise its temperature by just one degree.
Answer:
11.48 m
Explanation:
The following data were obtained from the question:
Mass (m) of the roller coaster = 1200 Kg
Initial velocity (u) = 15 m/s.
Final velocity (v) = 0 m/s (at highest point)
Acceleration due to gravity (g) = 9.8 m/s²
Highest point (h) =?
The highest point reached by the roller coaster can be obtained as illustrated below:
h = u²/2g
h = 15² / 2 × 9.8
h = 225/19.6
h = 11.48 m
Therefore, the highest point reached by the roller-coaster is 11.48 m
Answer:
Explanation:
= 250 moles.
N = n×6.02×
= 1.505×
Total charge = (1.505×) × (1.6×)
= 2.4× C.
Answer:
When two forces acting on an object are equal in size but act in opposite directions, we say that they are balanced forces.
