1. What is the expected charge to mass ratio for an electron based on the unknown values for the charge and mass of an electron? 2. Comment on the accuracy of your results. Does your results agree with the expected charge to mass ratio for an electron

1 Will a body moving in a circular track have zero acceleration? Vividly explain your making reference to both radial and perpendicular acceleration?     In your own words describe first moment of area for any shape and its With reference to the shape below about the axis s – s, describe the position of the centroid.             In quantum mechanics, the fundamental constant called Planck’s   constant, h, has dimensions of   ML2T -1   . Construct a quantity with the   dimensions of length from h, a mass m, and c, the speed of light.         2   Explain why the vertical component of the velocity (Vy) of a projectile motion is zero at the maximum height but the Horizontal Component of the velocity (Vx) is constant thorough out the parabolic motion?   Prove that, the range, R the time of flight, T and the Maximum height, H by a projectile are respectively given by;   ,                                         and           You are on an island and you have two coconuts.…

5. Why is it important to include background information in your lab report? O to help other scientists better replicate your experiment O to prove that the results of the experiment are sclentifically valid O to give your readers a summary of the results of the experiment O so your readers can understand relevant context for the experiment

A mass spectrometer is being used to monitor air pollutants. It is difficult, however, to separate molecules with nearly equal mass such as CO (28.0106 u) and N2 ( 28.0134u). How large a radius of curvature must a spectrometer have (Figure 1) if these two molecules are to be separated on the film by 0.65 mm ?

Ion Thrusters I: The Electric Field. You and your team are designing a new propulsion engine that ejects xenon (Xe) ions in one direction, causing a spacecraft to accelerate in the opposite direction, in accordance with the conservation of linear momentum and the impulse-momentum theorem. This is exactly what happens when a rocket engine expels high velocity particles when burning fuel, except that in the case of the ion drive the ions are accelerated with an electric field. In this process, Xe gas atoms are ionized so that they each acquire a net charge of +e. They are then subjected to an electric field, which accelerates and ejects the ions from the engine. The final step is to infuse the ejected ion beam with electrons in order to neutralize the ions so that they no longer electrically interact with the spacecraft, or with each other. In the thruster you are designing, assume that the Xe atoms accelerate from rest in a uniform electric field over a distance of 0.110 m before they…

An electron is in motion at 4.0 x 10° m/s horizontally when it enters a region of space between two parallel plates, as shown, starting at the negative plate. The electron deflects downwards and strikes the bottom plate. The magnitude of the electric field between the plates is 4.0 x 102 N/C and separation between the charged plates is 2.0 cm. d = 2.0 cm a. Referring to the above image, state the sign of the charge on each electric plate: i. Sign of bottom plate - ii. Sign of the top plate- b. Determine the acceleration of the electron between the plates. C. Determine the horizontal distance travelled by the electron when it hits the plate. d. Determine the velocity of the electron as it strikes the plate. |拉 0

MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER A pulsar is a type of rotating neutron star that emits a beam of electromagnetic radiation. Imagine a pulsar that is moving toward Earth at a speed of 856.500 km/s. It emits mostly radio waves with a wavelength (at the source) of 132.500 cm. What is the observed wavelength of this radiation on Earth? (Assume the Earth is stationary. Consider the speed of light c = 3.00000 × 108 m/s. Give your answer to at least six significant figures.) 4.0 133 What relationship describes the frequency of a wave for an observer that is moving relative to the source? What is the relationship between frequency and wavelength? cm

I tried this problem and I asked my professor about it and he tells me I got all of the answers wrong and I don't know why I keep getting the wrong answer. Can you help me with Part A,B, AND C and can you label which part is A,B, and C

Star Energy UNIT 4 The diagram above shows a conceptual model of a spherical star that generates and emits light energy. Here are the assumptions we will make about the star: · Each cubic centimeter of the star's interior generates 3x10 watts of power. · Each square centimeter of the star's surface shines 6,000 watts of power into space. (a) Suppose the star has a radius of about 7×10° cm. How much power would the interior of the star generate? How much power would the star's surface shine into space? Which quantity is greater? (b) Suppose the star has a radius of about 5×10" cm. How much power would the interior of the star generate? How much power would the star's surface shine into space? Which quantity is greater? (c) Life on Earth depends on our Sun maintaining equilibrium, neither growing nor shrinking. Likewise, in this conceptual model of the star, if the star is too small, then the number of watts leaving the surface will exceed the number of watts generated in the interior,…
