(a)
The other particle emerged from the nitrogen gas in Rutherford Scattering experiment in which he bombarded a sample of nitrogen gas with a beam of alpha particles.
(a)

Answer to Problem 1CQ
Proton is the other particle emerged in the experiment.
Explanation of Solution
Given info: Rutherford bombarded a sample of nitrogen gas with a beam of alpha particles.
Proton is a positively charged particle with magnitude is equal to that of electronic charge .the mass of the proton is
In Alpha particle scattering experiment, Along with the deflected alpha particles, a positively charged particles were emitted. Rutherford observed the new particle behaving like nuclei of hydrogen atom.
By repeated experiment with gases he confirmed that it is new particle in side the nucleus and called as proton.
Conclusion:
Thus, Proton is the other particle emerged in the experiment.
(b)
The conclusion of the experiment.
(b)

Answer to Problem 1CQ
The protons are coming from the nucleus because no proton presented in the initial state.
Explanation of Solution
In the alpha particle experiment the mass of the a beam of alpha particles were bombarded with nitrogen gas while only few were deflected most of them passed through the gas. A new particles were observed with positive charge with magnitude equal to electronic charge.
These particle behaved like hydrogen nucleus and Rutherford observed these particle in other gas medium like helium, nitrogen and carbon. So he confirmed that hydrogen nucleus is a basic constituent of the nucleus of other elements. This particle named proton. Since only few observed he confirmed it is coming from the nucleus.
Conclusion:
Thus, the protons are coming from the nucleus because no proton presented in the initial state.

- Jack Sparrow and his crew snuck up on their enemies by submerging an upturned wooden rowboat and breathing in an air pocket in the upside-down boat's cavity. What stupidly large force would be needed to hold such a boat underwater? The total volume of the wood is 0.0686 m3 and the density of the boat is 380. kg/m3. It will hold 5.28 m3 of air which has a density of 1.20 kg/m3. The density of water is 1000. kg/m3.arrow_forwardA high-speed lifting mechanism supports an 881 kg object with a steel cable that is 22.0 m long and 4.00 cm^2 in cross-sectional area. Young's modulus for steel is 20.0 ⋅10^10 Pa. The elongation of the cable is 2.377x10^-3 m. By what amount does the cable increase in length if the object is accelerated upwards at a rate of 3.11 m/s2?arrow_forwardLet us assume you are lifting out a 179 lb sheep. The density of the air around the balloon is 1.23 kg/m3 and the density of the air inside the balloon is 0.946 kg/m3. If the sheep accelerates upwards at 4.84 m/s2, what is the volume of the balloon? 1 kg = 2.20 lbsarrow_forward

- Draw a third quadrant vector C. (remember that boldface characters represent vector quantities). Show the standard angle 0 for this vector (= angle that C makes with the positive x- axis). Also show the angle that C makes with the negative y-axis: call the latter angle 8. Finally, show the smallest angles that C makes with the positive x-axis and the positive y-axis: call these angles p1 and p2, repectively. a) Prove the following formulas for the components of C involving the standard angle (hint: start with the formulas for the components based on the angle & and then use (look up if necessary) co-function identities linking cosine and sine of 8 to sine and cosine of 0 since 8 = 3π/2-8 (this will switch cosine and sine around and eliminate - signs as well)) - C=Ccose C₁=Csine b) Prove the following formulas for the components of C: C=Ccosp1 C=Ccosp2arrow_forwardNotation matters when working with vectors! In particular, it is important to distinguish between the vector itself (A) and its magnitude (A). Illustrate in four separate sketches that each of the following statements is possible: a) both R = A + B and R=A+B are correct b) R = A + B is correct, but R=A+B is incorrect c) R = A + B is incorrect, but R=A+B is correct d) both R = A + B and R=A+B are incorrectarrow_forwardYou know from your math courses that an infinitesimal segment of a circular arc can be considered as a straight line segment. Imagine that you cover a full circle in, say, the clockwise direction, with infinitesimal displacement vectors dr. Then evaluate fdr and fdr (the circle symbol on the integral just reminds us that we have to go around the full circle).arrow_forward
