A museum curator pulls a 150 kg sculpture across the museum floor, with an acceleration of 0.5 m/s2. If the coefficient of sliding friction between the floor and the sculpture is 0.57, calculate the force with which the curator pushes the sculpture.

waves moving from a fast medium to a slow medium will experience a reflection as light travels more slowly than red light. total internal reflection occurs when the critical angle is.

that would be because of both gravity and friction. so     c

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
