A goose is flying south for the winter at a constant speed. Keep in mind that one mile is 1.61 km, and one pound is 454 g.The go
1 answer:
Answer:
kinetic energy = 84.0260 joules
Explanation:
given data
one mile = 1.61 km
one pound = 454 g
mass = 20.1 lb = 9.1172 kg
flying velocity = 9.60 miles/h = 9.60 × 1.61 × = 4.2933 m/s
solution
we get here kinetic energy that is express as
kinetic energy = 0.5 × m × v² .........................1
put here value and we get
kinetic energy = 0.5 × 9.1172 × 4.2933²
kinetic energy = 84.0260 joules

Answer: a) anode
b) positive
c) cathode
d) anode to cathode
Explanation:
Galvanic cell is defined as a device which is used for the conversion of the chemical energy produces in a redox reaction into the electrical energy.
In the galvanic cell, the oxidation occurs at an anode which is a negative electrode and the reduction occurs at the cathode which is a positive electrode. Thus the electrons are produced at anode and travel towards cathode.
Due to loss of electrons at anode, positive charge in concentrated in anode and negative charge is concentrated in cathode. To balance these charges , positive ions or cations from salt bridge move towards cathode and negative ions or anions from salt bridge move towards anode.
The balanced two-half reactions will be:
Oxidation half reaction :
Reduction half reaction :
Thus the overall reaction will be,
