Use the periodic table of the elements to answer the following : a) What is the resulting element when the nucleus of a Chlorine atom absorbs a proton. b) A banana is naturally radioactive as it has the potassium-40 isotope and naturally undergoes beta-minus decay. What element does it decay to? c) Write the formula for the beta-minus decay including the correct superscript and subscript for potassium 40 and d) Describe the ejected particles and what can be used to shield or block this radiation

Friction force is equal to the net force of the car.             fn                           |ff< ·                       |                     fgfg and fn cancel out.55 km/h is 15.2778 m/s. this is the initial velocityfinal velocity is 0 m/sfind acceleration using kinematic equationv² = v₀² + 2adsince v = 00 = v₀² + 2ada = -v₀²/(2d)a = -(15.2778 m/s)/(2 * 38m) a = -3.2418 m/s²find net force and you find friction.f = ma f = (1165 .2418 m/s²)f = 3776.7 n = ffw = ff · dw = (3776.7 n)(38 m)w = -1.4 × 10^5 jthe friction forces do 1.4 × 10^5 j of work on the car
