An alpha particle is accelerated by a voltage of 1.53*10^3 V and is then deflected by a magnetic field of strength 0.020 T into a circular path of radius 0.40 m. If the alpha particles have a charge of 3.2*10^-19 C, what is their mass?
Answer this Question
The velocity of a particle on the x-axis is given by the differential equation dx/ dt= t^2/ 2 and the particle is at x = 4 when t = 2. The position of the particle as a function of time is: A. x(t) = t^3 / 6 - 26/3 B. x(t) =t +2 C. r(t) = t - 2 D. x(t) =
The velocity-versus-time graph is shown for a particle moving along the x-axis. Its initial position is x0 = 1.8m at t0 =0s. Part A What is the particle's position at t=1.0s? Part B What is the particle's acceleration at t= 1.0s? Part C What is the
Having trouble with this questions. Please help. A particle moves on the x-axis so that its position at any time t (is greater than or equal to) 0 is given by x(t) = 2te^-t a) Find the acceleration of the particle at t=0 b)find the velocity of the particle

In Rutherford's famous scattering experiments that led to the planetary model of the atom, alpha particles (having charges of +2e and masses of 6.64 × 10−27 kg) were fired toward a gold nucleus with charge +79e. An alpha particle, initially very far
Physics. Pleaseee helpppp
Four electrons are located at the corners of a square 10.0nm on a side, with an alpha particle at its midpoint. How much work is needed to move the alpha particle to the midpoint of one of the sides of the square?

Hi! I am taking the Unit 8 Lesson 10 chem test now and I have a C in this class so I need to get all the answers correct... If you don't know all that's ok but if you know some please help, thank you! (Connections Academy) 1. In a nuclear reaction, which
The position of a particle moving on a horizontal line is given by s(t)=2t^3-15t^2+24t-5, where s is measured in feet and t in seconds. a: What is the initial position of the particle? b: What is the average velocity of the particle on the interval
A particle is moving along the curve below. y = sqrt(x) As the particle passes through the point (4,2), its x-coordinate increases at a rate of 4 cm/s. How fast is the distance from the particle to the origin changing at this instant?
Particle 1 carrying -4.0 μC of charge is fixed at the origin of an xy coordinate system, particle 2 carrying +8.0 μC of charge is located on the x axis at x = 2.0 m , and particle 3, identical to particle 2, is located on the x axis at x = -2.0 m . Part
