May 2, 2017 · The previous post demonstrates the effect of the measurement errors that can creep in if you are predicting the period using the given formula #T = 2 pi sqrt("l/g")#.

Dec 2, 2014 · Density is the mass per unit of volume of a substance. The density equation is: "Density" = "Mass"/"Volume" To solve the equation for Mass, rearrange the equation by multiplying both sides times Volume in order to isolate Mass, then plug in your known values (Density and Volume). Then solve for Mass. "Mass" = "Density x Volume" Example The …

Feb 1, 2018 · I am gonna describe here three theories which led to the formation of the earth.. 1. The core acceleration model:- During the formation of universe the sun became to formed in the center of the nebula. But as we know there were also other materials which were in the space, which were mostly small due to gravity became bound together to form the larger particles.. …

Mar 14, 2016 · Everything would float off the planets. Then suffocate. And then promptly burn to a crisp First thing you'd notice if gravity stopped working is that you'd no longer be able to keep your feet on the ground. Without gravity, everything on the surface of the Earth will start floating off. Animals, people, cars, ships, the water on which the ships float, pretty much everything not …

Feb 20, 2017 · Gluons and the bosons which mediate the interaction. The weak force is a fundamental force which causes beta radioactivity. It can convert a proton into a neutron, a positron and an electron neutrino. The W and Z bosons mediate the interaction. Gravity is the fundamental interaction which causes masses to attract each other.

Apr 18, 2017 · Is gravity an action-at-a-distance force? What is the size of the electic field inside a charged conductor? How can the strength of an electric field be quantified?

Mar 10, 2018 · "26 Joule" According to the work-energy theorem, the net work on an object causes a change in the kinetic energy of the object. Change in Kinetic energy = Work done on object ∆"K.E" = F × d = "4.0 N" × "6.5 m" = "26 Joule" Therefore, block gains "26 Joule" of …

Aug 15, 2015 · Capillary action is the ascension of liquid through a slim tube. It is the intermolecular forces that allows the liquid to be attracted to one another while in the tube. This is call cohesion, which allows them to maintain their shape while being attracted to the tube. Note that capillary action only occur when adhesive forces are stronger than cohesive forces, which …

Nov 21, 2015 · A 59 kg skier starts from rest at height H = 25 m above the end of a ski-jump ramp (see the figure). As the skier leaves the ramp, his velocity makes an angle of θ = 20° with the horizontal. ?

Nov 8, 2017 · The Sun is much more massive than the Moon and it is also 150,000,00km away. The Sun's gravity is also much stronger than that of the Moon. Gravity strength is inversely proportional to the square of the distance apart. This means that the gravity strength on the side of the Earth facing the Sun is not much different to that on the side facing ...
