Now, the velocity of the particle is always tangent to the curve. If we set v as the magnitude of the particle velocity, then Using the chain rule of Calculus we can write Since, we can write This gives us Substituting equation (4) into equation (3) we get As a result, ...
The power equation is: P = VI where: P is power in watts (W) V is voltage in volts (V) I is current in amperes (A). This formula tells us that the power consumed by an electrical device is directly proportional to the voltage applied to it and the current flowing through it. ...

path for larger clients and is closing the gap between our current marketplace and enterprise offerings. The launch of Business Plus is unlocking a higher velocity approach to the enterprise market with both sales and self-service channels working in tandem to activate and retain high-value ...
The specific work can on basis of the energy equation be expressed with the head as: w = g h (6) where h= head (m) g= acceleration of gravity (m/s2) Transformed to express head: h = w / g (7) Example - Specific Work of a Water Pump A water pump works between 1 bar (105...
The quantity 12mv212mv2 in the work-energy theorem is defined to be the translational kinetic energy (KE) of a mass m moving at a speed v. (Translational kinetic energy is distinct from rotational kinetic energy, which is considered later.) In equation form, the translational kinetic energy,...
For example, if the predicted maximal heart rate is 200 beats per minute (BPM) and the test target heart rate of 90% of 200 BPM is achieved at a work load of 8 METs, then the max functional capacity may be estimated from the equation: 8 METS = 90% of maximal functional capacity; ...
The laboratory work consists in two parts, in which students first determine the enzyme concentration and the time to be used in the following session to obtain the kinetic parameters (KM and Vmax) by non‐lineal fitting of the Michaelis–Menten equation to the initial velocity dependence with ...
If the displacement is along a circular path, then the direction of linear velocity at any instant is along the tangent at that point. The speed is the rate of change of linear displacement of a body with respect to the time. Since the speed is irrespective of its direction, therefore it...
