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.
Answer:
13 atoms
Explanation:
Look at the subscripts.
“Mg₃” means that there are 3 magnesium atoms; “PO₄” means that there is 1 phosphorus atom and 4 oxygen atoms. But note that the PO₄ group has a subscript too: 2. This multiplies the atom count by 2, so you have 2 phosphorus atoms and 8 oxygen atoms.
3 + 2 + 8 = 13
(hope this helps can i plz have brainlist :D hehe)
The radio waves travels between the two boxes and they were travelling through air,
- Box B captures, amplifies and demodulates radio waves.
- Box A modulates, amplifies and send out radio waves.
<h3>What are radio waves?</h3>
- Radio waves are the type of radiation from the electromagnetic spectrum.
- The radio waves can be used in communication technologies like computer, phones, radios , etc..
- Radio waves have lower frequencies but longer wavelength.
- These devices will get signal and then it transmit as mechanical waves through sound.
In that way, the radio waves from box A to B through air, the box A will gets the signal, and then modulates, amplifies and then it send out radio waves. Through the air, Box B will captures, amplifies and demodulates radio waves.
