In an cnclosed elevator and if you know your weight on earh, can you dectermine. of gravity if the elevator is a accelerating upwand c moving up at constant speed. accelerating downward f in free fall.

graph slopes whilst gas cools, then it is flat whilst conensation to liquid happens, the coolong liquid then graphs as a slope when it solidifies graph is flat

latent heat

laticia draws the diagram below to show earth’s magnetic field.

answer

the arrows to the right of earth should point up.

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards

find the sum of the two horizontal vectors and the sum of the two vertical vectors
