how do I linearise :
mgh=1/2(M+m)v^2 ?
This is what I did. r = (m*v) / (qB) To find v, v= sqrt( 2*q*V/m) = 37013.9 and I put this number and the given numbers to find 'r', but I got it wrong. What did I do wrong? I. Suppose that an ion source in a mass spectrometer produces doubly ionized gold ions (Au2+), each with a mass of 3.27 × 10-25 kg The ions are accelerated from rest through a potential difference of 1.40 kV. Then, a...
how do i find H, and how do i use the equation on the 4 question to find Ei and Ef where m is the mass of the hanging mass, M is the mass of the Smart Cart, h is the height of the hanging mass above the floor, H is the height the Smart Cart (mass M) climbs up the track, and v the velocity of the Smart Cart in the instant when the hanging mass is about to...

the formula for potential energy is p= mgh, where Pis potential energy, m is mass, g is gravity, and h is height. which expression can be used to represent g?1 p-m-h2 p-mh3 p/m0-h4 p/(mh)
mgh 3. In this question you will do some algebra to determine two relations that you will need for Part 2 of this lab. Write down Eq. 11 twice. In the first statement, set the rotational kinetic energy term equal to zero (i.e. 1/2lo 0) -call this your "No Krot model". Leave the second as it is written in Eq. 11 call this your "Krot model". For both models, solve for v in terms of g, h, and a. In...
how do I prove Lf = L/2*mv? A thin rod of mass M and length L is struck at one end by a ball of clay of mass in, moving with speed v as shown in the figure. The ball sticks to the rod. Determine the angular momentum of the clay-rod system about A (the midpoint of the rod) after the collision.
How do I get the change in V? why is it 1.5? Also why is change in T equal to 84? When I did the experiment, I obtained: Temp (°C) Vol (mL) T(K) 22 62 Room temp Hot bath Ice bath Alcohol bath 6.0 6.8 5.6 5.3 295 335 275 2 -22 251 m = (change in V) + (change in T) = 1.5 + 84 = 0.018 so: V = 0.018 T+C
How do I make 95% v/v ethanol that has a density of 0.7893 g/mL?
I need help with question 2b and 3. Please help it would be awesome if i knew how to do these questions. v=(2,-4) w=-3i+2j 2. Let and ui be as in Problem 1. Find the following quantitics (a) 2u) (ui-2t). (b) The angle between the vectors (2u) and (wi-2) 3. Let be the line defined by 2r +3y 1. (a) Find an equation of the line parallel to I, running through the origin. (c) Find an equation of the line...
The electric field between two parallel plates connected to a45-V battery is 1500 V/m. How far are the plates? I have to find the "d" distance between the plates but how do Imanipulate the equation? The equation I have to use is: E= Vba/d I have Vba which is 45 V and 1500 V/m. d= Vba/E is this correct? Thanks
