Scientists are able to use body waves to determine what makes up the different layers of the Earth's interior. What characteristics to the body waves have allow scientists to do this? Rayleigh waves travel through liquids and solids while Love waves only travel through solids.
P-waves travel through liquids and solid while S-waves only travel through solids.
Love waves travel through liquids and solids while Rayleigh waves only travel through solids.
S-waves travel through liquids and solids while P-waves only travel through solids.

dopamine..

"it was found that some people who were taking the drug l-dopa to raise their levels of dopamine were developing schizophrenic-like symptoms supporting research a strength of the dopamine hypothesis is that there are many studies which have shown support for the neurochemical explanation."

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.

distance = 150m

displ = root (50 ^2 + 100^2)

root(2500+10000)

root 125000
