Answer:
a) 70,560 J
b) 88.2 N/m
Explanation:
The spring potential will equal the change in gravity potential
PS = PE = mgh = 80(9.8)(100 - 10) = 70,560 J
PS = ½kx²
k = 2PS/x² = 2(70560)/(100 - 50 - 10)² = 88.2 N/m
Volcanic islands, Mountain ranges
Explanation:
A convergent margin is plate boundary in which plates comes together. There are different types of interactions that occurs around a place where plate converges.
- An ocean-continent convergence creates a subduction zone in which the denser oceanic plate sinks beneath the less dense continental crust.
- As the oceanic plate begins to subside, it can melt and form chains of volcanic island within the riding continents.
- Also, where two plates of equal densities converge, none of them subsides and this leads to upbuilding.
- The product can be seen as extensive mountain ranges on earth like the Andes and Himalayas.

The wavelength is the so-called "fundamental" wavelength, or the "first mode." Thus, the wavelength of the string's vibration is defined by the supports, and has nothing whatsoever to do with mass or elasticity.
Answer:
B it decreases
Explanation:
the movement of a positive test charge in the direction of an electric field would be like a mass falling downward within Earth's gravitational field. Both movements would be like going with nature and would occur without the need of work by an external force. This motion would result in the loss of potential energy
