Answer:
a) m = 7000 - 500 = 6500 g
b) ρ = 6500 g / 5000 cm³ = 1.3 g/cm³
c) Brush floats because its density is less than that of the paint and displaces its own weight in the paint.
Hey there!
Your answer is C, for circuit- ironic.
Here's why:
A circuit is made of things like insulators, transistors, and conductive material, all in a loop for electricity to travel through. The loop has to be intact and be able to let electricity pass through to do its job.
Therefore, it's not the same as a conductor or insulator, and it can't be broken.
Hope this helps!
We know that V=E/Q Where V is the PD, E is the energy, and Q is the charge.
Substituting in the values gives V=48/4=12
Therefore the PD across the circuit is 12V
Answer: 131.14km per day
Explanation: since the second half of the terns migration takes 122 days we can assume that the full migration would take 244 days. using this we can divide the total distance by the total amount of days it takes (because speed = distance/time) which is 32,000/244, which would be 131.14
