Aparticle of mass m is constrained to move on a circle of radius r. the circle in tur rotates with constaut angular velocity about an axis orthogonal to its plane and passing through some point p on its circumference. show that (a) the motion of the particle with respect to an axis passing through p and the center of the circle is that of a planar pendulum in uniform gravitational field. (b) calculate the total energy e and angular momentum l. show that e -l-s is a constant of the motion. are e& l themselves constants?

it is the second option.

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!

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
