270x42=11,340.J
Answer:
The weight of body is 1.3040 gram.
Explanation:
Given that,
The weight y of a fiddler crab is directly proportional to the 1.25 power of the weight x of its claws.
Suppose a crab with a body weight of 1.8 gram has claws weighing 1.1 gram.
Estimate the weight of a fiddler crab with claws weighing 0.85 gram.
Determine the weight of crab body
We need to calculate the value of proportional constant



Put the value into the formula


We need to calculate the crab weight

Here, x = 0.85 g
Put the value into the formula


Hence, The weight of body is 1.3040 gram.
Groups and periods are two ways of categorizing elements in the periodic table. Periods are horizontal rows (across) the periodic table, while groups are vertical columns (down) the table. Atomic number increases as you move down a group or across a period.
Electrons have a negative charge, so if you give away electrons, you give away negative charge, thus ending with a positive charge.
