Hi guys i have a question do you know how tsunami make us change

to be honest as much as i would love to answer this. i feel as if something's missing. just saying.

grav forces affect all objects magnetic forces affect magnetic objects and electric currents

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg
