100 ! me! i dont understand
3. for part 3, describe the motion of the ball as it moves from the top of the ramp and comes to rest against the block. explain how the motion changes in terms of the velocity, distance, acceleration, and force that you measured. use your data and newton’s laws to calculate these values and explain the situation. include the tables you used to calculate average initial velocity and average displacement. also, show your work for your calculations of acceleration and net force.

here are the kinematic equations:

Space-time metric ds2= -dt2+at2dx2+bt2dy2+ct2dz2 (a)how does the area of a rectangle with vertices at ( x=0, y=0, z=0 ), (1,0,0 ), ( 0,1,0 ) and (1,1,0 ) changes with time? (b) if a photon moving in the x direction starts from the origin at t=1, when does it reach x=l? (ds=0 for the trajectory of a photon.) (c) the proper time for a particle is defined by cd=ds. what is the proper time for a particle to move along the trajectory ( x(t)=t, y(t)=0, z(t)=0 ) from t=0 to 1 ? what is the condition on the parameter a so that the velocity of the particle never exceeds the speed of light ?

Consider a hydrogen atom in the ground state. what is the energy of its electron? =e= jj now consider an excited‑state hydrogen atom. what is the energy of the electron in the =5n=5 level? =e5= j

The solid that is formed and usually sinks to the bottom of a solution is the
