Answer: Protons
Explanation: The atomic number is the number of protons that are in the nucleus of an atom. Each element on the periodic table is defined by the number of protons. In other words, the protons/atomic number determines what element it is. Protons carry a positive charge.
Answer:
F= 2569.6 X 4.65 = 11,948.64
*Multiply the mass and the acceleration to find the force
Explanation:
For the answer to the question above,
Ricardo goes a distance (magnitude) of 27, in a direction of 60 degrees W of N
<span>Jane goes a magnitude of 16 in a direction 30 degrees S of W </span>
<span>How I would solve this is to imagine that the started at (0,0) </span>
<span>And their walking represents vectors. </span>
<span>Ricardo: </span>
<span>X-coordinate = -27sin60 = 27sqrt(3)/2 = 23.383 </span>
<span>Y-coordinate = 27cos60 = 27/2 = 13.5 </span>
<span>So, after he walks, he is at point (-23.383, 13.5) </span>
<span>Jane: </span>
<span>X-coordinate = -16cos(30) = 16sqrt(3)/2 = 13.856 </span>
<span>Y-coordinate = -16sin(30) = 16/2 = 8 </span>
<span>So, after she walks, she is at point (-13.856, -8) </span>
<span>So, you have 2 points. </span>
<span>Use the distance formula to find their distance apart </span>
<span>Sqrt((-23.383+13.856)^2+(13.5+8)^2) = 23.516m </span>
<span>To find the direction, simply find the slope of the two points, and take the arc-tangent. </span>
<span>The slope = -9.527/21.5 = -0.443 </span>
<span>Take the tan^-1 of this, which is -23.899 degrees. </span>
<span>This basically translates to, Ricardo must walk 23.899 degrees E of S </span>
<span>They will be 23.518 m apart </span>
<span>Ricardo must walk 23.899 degrees East of South to get to Jane</span>
1 lb = 4.45 Newtons (rounded)
199 lbs = approx 885 Newtons
Answer: The strong nuclear force.
Explanation: The strong force holds the protons and neutrons together in the nucleus. Despite being the strongest force, it has a very small range. (Think about how small an atom is) The strong force is thought to occur due to the exchange of pions between the protons and the neutrons. Since pions have a very short lifespan, the protons and neutrons must be very close to each other in order to exchange them. This phenomenon is what keeps the protons and neutrons so tightly binded together in the nucleus.
