part one:
a force f~ = fx ˆı + fy ˆ acts on a particle that

undergoes a displacement of ~s = sx ˆı + sy ˆ

where fx = 1 n, fy = −4 n, sx = 1 m, and

sy = 2 m.

find the work done by the force on the

particle.

answer in units of j.

part two:
find the angle between f~ and ~s.
answer in units of ◦

Could someone . i have tried to solve myself but my calculation is off

Which of these statements best explains how the hydrosphere interacts with the atmosphere to affect global climate? mountains block rain clouds and cause changes in global rainfall and evaporation. humans burn fossil fuels to produce greenhouse gases which cause global warming. humans cut down trees which affects the amount of oxygen in different parts of the globe. greenhouse gases, like carbon dioxide, dissolve in oceans and prevent global warming.

It takes a lot of energy to get the temperature of water to increase and eventually boil because water has a high heat.
