Asana. Now raise whole body towards sky in such a way that that only shoulder and head is on the ground .  While inverting yourself balance your raised body with the help of your hands holding the back with bent elbows on the the floor ,making broad base for supporting upright straight body.  Try to keep raised part of body straight as shown in picture.  During this maintain normal breathing and stay in the posture for a while.  Now slowly slowly bring down raised part of body on the…

proven through Newton’s second law, F=ma (Force=mass*acceleration). Rearranged, this gives a=F/m, where acceleration can also be gravity, if falling down. Another equation is a=v/t (acceleration=velocity/time) and a=(√2s)/t (acceleration=(sqrt2*distance)/time). The research question that this investigation will explore is: How is the drop time of a parachute affected by its mass? Photo 1: Parachute…

Current 4.2 A Angle 1.8° Torque 8.34 N.m The desired torque calculated to withstand the mirror weight, friction and air resistance is 69.75Nm. This torque cannot be satisfied by the stepper motor on its own since the torque the stepper motor can carry is 8.34 N.m. A worm gearbox is thus required in this situation to help raise the torque and withstand the mirror weight, friction and air resistance. Figure ‎2-14: Worm Gearbox The gearbox has reduction ratio of 16. The motor and gearbox…

Drag force is an aerodynamic force which acts parallel and opposite to the motion of the object when it moves through a fluid. It is caused by friction and differences in air pressure. There are many factors can affect the magnitude of drag force as with aircraft lift. The drag depends linearly on the shape and size of the object moving through the air. The object’s cross-sectional shape determines the form drag which is created by the pressure variation around the object and affects the…

Langmuir isotherm The Langmuir adsorption model is established on the following hypotheses: (1) uniformly energetic adsorption sites, (2) monolayer coverage, and (3) no lateral interaction between adsorbed molecules [26]. A mathematical expression of the Langmuir isotherm is given by the following equation: Where qe (mg/g) is the amount of dye adsorbed on the solid adsorbent at equilibrium, qm (mg/g) is the maximum adsorption capacity, KL (L/mg) is the Langmuir equilibrium…

Question 2: Map scale is the ratio of the straight line distance between any two points on a map to the straight line distance between the same two points on the earth’s surface. Now when looking at map scale there a few concepts for instance, ratio (representational fraction) scale is a concept of map scale. Ratio scale is always neutral in the scale measurement used on the map. So when looking at a map scale of 1:50 000 it means that 1 unit of measurement on the map is equal to 50 000 of the…

is when external forces acting on a particle are balanced (zero resultant), the particle will be in equilibrium. But when external forces acting on a particle are not balanced, the particle will move in the direction of the resultant with magnitude ma. We use Newton’s second law to calculate the acceleration of a particle. Once the acceleration of a particle is known, we can apply equations of kinematics to obtain the…

as how quickly and in what direction velocity changes. The equation for acceleration is: a=∆v/∆t in which the variable a represents acceleration, ∆v represents the change in velocity, and ∆t represents the time interval. In addition, gravity is the force that attracts a body towards any physical body that has mass. Galileo Galilei discovered that the distance a standard accelerating object travels is proportional to the square of the…

unbalanced force” In this video the athlete is at rest when he is first on the starting block. He is being acted upon by normal force between him and the block. When he bends down to pull with all his strength on the block he is creating a tension force between him and the block. He then gets power and pushes off the block with both feet. He is accelerating into the air and being acted upon by an unbalanced force. He is changing his motion and is no longer in constant motion.…
