When a force is applied to an object and the object moves in the direction of the force, work is done. Which of the following is a correct expression of work in English? A. Force multiplied by distance. B. Force divided by distance. C. Distance multiplied by time. D. Distance divided...
If the body is not moving , then static frictional force comes into play .Static friction is a self adjusting force , hence when the applied force is doubled ,then friction becomes double . But when the object is moving, then kinetic friction comes into play. And when applied force is gr...
14 (a) A force is applied across the ends of a sample of wire. For small forces the deformation of the wire is elastic and for large forces the deformation is plastic.Explain what is meant by the terms(3)elastic deformation plastic deformation(b)Copper is a ductile material. This mak...
13 A constant force F is applied to a stationary object of mass m on a frictionless surface. A constant acceleration increases the velocity of the object to some value v in a time t. It covers a distance s during this time.Which value of the kinetic energy is given to the object? C...
athe flat surfaces are to be brought in contact with the cells and the crushing is to be continued until an applied force of 13KN is reached.once the maximum force has been obtained it is to be released. 平面将被带来与细胞联系,并且击碎将继续,直到13KN应用的力量是最大力量得到了它将被发布...
friction is a force exerted by a surface against the motion of a body across its surface. friction is the reason why your car comes to a standstill if you don’t press the accelerator. the frictional force is opposing the rotation of the wheels of your car. therefore, if you leave the...
aThe flat surfaces are to be brought in contact with the cells and the crushing is to be continued until an applied force of 13 ±1.0 kN (3000 ±224 pounds) is reached. 平面将被带来与细胞联系,并且击碎将继续,直到13 ±1.0 kN (3000 ±224应用的力量磅)被到达。 [translate] ...
horizontal. The crate is on a ramp that is inclined at an angle of10°above the horizontal. Calculate the amount of work done on the crate by the applied force as the crate is pushed7.5mup the ramp. There are 2 steps to solve th...
But is security by obscurity always bad? In this article, we will explain what security by obscurity is, attempt to shed some light on why many consider it a waste of time (and others don't), and show you why the answer, as usual, is far more complicated than it seems at first. ...
