Objects with masses of 110 kilogram and a 410 kilogram are separated by 0.390 meter.
(a) Obtain the net gravitational force exerted by these objects on a 38.0 kg object placed midway between them.
N
(b) Find at what position can the 38.0 kg object be located so as to experience a net force of zero?
m from the 410 kg mass
You combine two thin lenses by placing them in contact so that their axes coincide, forming what is called a compound lens. The focal lengths of the lenses are 24.1 cm and –53.9 cm, respectively. Find the focal length of this compound lens?__________..
Using your knowledge of statics, discuss briefly why the magnitude and direction of the knee reaction force varies with the amount of lower leg flexion and the amount of added weight.
Transverse waves with a speed of 43.0 m/s are to be produced on a stretched string. A 5.40-m length of string with a total mass of 0.0600 kg is used. (a) What is the required tension in the string? N (b) Calculate the wave speed in the string if the ..
Explain why do we place guards over capacitors and where does the guard voltage come into play when using an analogue L-C meter to probe the capacitance?
A viscous fluid flows in a 0.10-m-diameter pipe such that itsvelocity measured 0.012 m away from the pipe wall is 0.8 m/s. If the flow is laminar, determine the centerline velocity and the volumetric flow rate.
