A: A resource that will always be there, can be replenished by the biogeochemical cycles. B: Can regenerate if they are alive or can be replenished by biochemical cycles if they are non living.
- Dmitri Mendeleev- arranged elements according to their
atomic mass
- Johann Wolfgang Dobereiner-created groups of three elements,
each based on similar properties
- John Newlands-used patterns to predict undiscovered
elements
- Antoine Lavoisier-divided elements into four categories
Explanation:
The periodic table or the table depicting the arrangement of various elements has a long history. Several of the scientist starting from Lavoisier to Mendeleev contributed to the table in their might. The present table has been an evolution of the previous tables over their shortcomings.
Some of the notable contributions include-
- Mendeleev- Mendeleev arranged the elements in order of atomic mass rather than atomic mass. Through this, he also discovered new elements.
- Newlands- He formulated the Newland law of octaves similar to musical notation.
- Lavoisier- Lavoisier divided the elements into various categories and also defined elements.
- Dobereiner- He formulated the triad law which encapsulated that certain group of elements showed similar properties, hence can be grouped together.
Answer:
58.37 V
Explanation:
Given that
Number of winding on coil, N = 80 turns
Area of the coil, A = 25 cm * 40 cm = 0.25 m * 0.4 m
Magnitude of magnetic force, B = 1.1 T
Time of rotation, t = 0.06 s
See the attachment for calculations
Since the question above is looking for the SPEEd of the WAVE, the formula that should be used is SPEED = DISTANCE / TIME. You just need to substitute the distance (36 meters) and the time (15 seconds) to the formula. You should be able to get SPEED = 2.4 m/s.
