AS Physics P1 MCQs Preparation Thread.
14) The horizontal velocity will remain the same. The vertical velocity will be zero at that time. So the kinetic energy will be due to horizontal velocity alone which is v*cos*45 = v √2/2 Kinetic energy at max point = 1/2 * m * (v √2/2)² = [1/2 m v² ]* 1/2 (the thing in square brackets is...- Thought blocker

25) The Y is half the amplitude of X = 8/2 = 4 And In onw oscillation of Y there is the frequency of 100Hz, so what will be the frequency of Y which oscillates 3 times when X does for 1, that would be 3 * 100 = 300Hz- Thought blocker

13) Basic concept of dynamics, forces. B is the answer, no explanations :P 14) (0.35*3*9.81)+(0.1*1.4*9.81=(0.15*6*9.81)+ans ans=2.8Nm 20) Take the leftmost column of liquid. There is a rule in fluid-statics that "the pressure in a sample of liquid is the same at any vertical height, as long...- Thought blocker

9) Force α Acceleration So when Force = zero, no change in speed, When force is constant, acceleration is also constant, so speed will increase linearly. 16) The vertical components of both H and W are cancelled by the upwards vertical component of T. Furthermore, T balances out the...- Thought blocker

21) 28) Simple, The flow of charge in electric field is from -ve ( tail) to +ve(head) So Electron will repel, so would move towards the tail, i.e is downwards. And As there wiuld be repulsion, it would repel with great force in electric field. 31) and 32) are again theory based, I won't...- Thought blocker

Taking a look at the image and the details we are given, it seems to be too cumbersome to count the waves at each point and check if they are 1/8th out of phase. In fact, determining what 1/8th out of phase is would be a big headache. So, let's turn to mathematics and try to form a "phase/wave...- Thought blocker

8) lets see the motion in XY initial velocity at x=v1 final velocity at y=v2 average velocity=distance/time (V1+V2)/2=40/12 equation 1 simplifying it we get V1+V2=6.67 now consider motion in XZ initial velocity at x=v1 final velocity=v3 V1+V2/2=(40+40)/(12+6) simplifying it we get V1+V3=8.89...- Thought blocker
