Seasons are a result of the inclination of a planet’s axial tilt being inclined from the normal of the planet’s orbital plane. for example, earth has an axis tilt of 23.4° (appendix f). using information about just the inclination alone, which planets might you expect to have seasonal cycles similar to earth, although different in duration because orbital periods around the sun are different?

can be answered using momentum.

momentum = p

p1= mass1 * velocity1

p1 = p2

therefore

p1 = 6kg * 4m/s

p1 = 24kgm/s

p2=m2 * v2

24 kgm/s = 7kg * v2

v2 = 24 kgm/s / 7kg

v2= 3.42 m/s

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 ! : )

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.
