The gravitational force that acts on a 1200 kg space probe on the surface of Mars is4.43 × 103 N.The radius of Mars is 3400 km.Without using the mass of Mars,determine thegravitational force that acts on the space probe when it is:a 3400 km above the surface of Marsb 6800 km ...
4-19c. In accordance with the principle of moments, the 200 sin 45°N moment of F computed about point A is equivalent to the sum of the moments produced by the two force components. Assuming counterclockwise rotation as positive, i.e., in the +k direction, we can apply Eq. 4-2 (...
1英语翻译1.Work is done on an object only when a net force acts on the object to displace it in the direction of a component of the net force.2.The amount of work done on an object by a force is equal to the component of the force along the direction of motion times the distanc...

本句是主谓结构，act是不及物动词。可以分析为：At such times,是状语 justice是主语 acts 是谓语like a living force可以看作是介词短语作方式状语。
A 2.0-N force acts horizontally on a 10-N block that is initially at rest on a horizontal surface. The coefficient of static friction between the block and the surface is 0.50. Suppose that the block now moves across the surface with const...
What force acts on the mass at {eq}t = 0 \ {/eq}? Finding the Force: we have to calculate the force acts on the mass at {eq}t=0 {/eq} For calculating the force we are going to use Newton's second law of motion...
3.Determine whether the inertia of an object changes as the object's velocity changes.4.Explain why an object with a smaller mass has a larger acceleration than an object with a larger mass if the same force acts on each.5.You push a book across a table.The book moves at a constant ...
(2) the impact of the disability on an array of variables, spanning from physical fitness to well-being, quality of life, sleep, and nutritional aspects, among others, which are known to mediate/modulate the effects of exercise on human health; (3) the variability of the parameters related...
