A seismologist plots the variation in velocity of P and Swaves in different layers of the Earth during an earthquake. The information is shown in the grap 15

What can be concluded from the graph?
The layers of Earth have different densities.
P and Swaves are absorbed in the core.
The layers of Earth do not have distinct boundaries.
Pand S waves always originate in the mantle and travel through the core.

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!

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

i need with 1.3.2 investigate cycling o2 and co2 apex

we need to see it

1.195000

explanation:

total mass=0.0117+0.0137+0.0881+0.0111

total mass= 0.01172kg

total velocity = 0.283-0.743+0.871-0.799+0.155+0.637+0.301=0.102

momentum=mv=0.1172*0.102=1.195000//
