I believe chemical change is the correct answer.
Silver is a chemical so it certainly will not deal with physical change or physical property.
It cannot be a property since it consists of only one element which is silver.
Since the total conductance is 0.0075 s, the total resistance is 133-1/3 ohms.
Answer:
810.94 m/s
Explanation:
Applying,
v = √(2gR)............. Equation 1
Where v = escape velocity of the spherical asteroid, g = acceleration due to gravity, R = radius of the earth
From the question,
Given: g = 0.636 m/s², R = 517 km = 517000 m
Substitute these values into equation 1
v = √(2×0.636×517000)
v = √(657624)
v = 810.94 m/s
Hence, the escape velocity is 810.94 m/s
