Answer:
Fnet = 20 Newton
Explanation:
Let the force applied by Brian be Fb.
Let the force applied by Alice be Fa.
<u>Given the following data;</u>
Force, Fb = 10N
Force, Fa = 30N
To find the net force, Fnet;
Net force can be defined as the vector sum of all the forces acting on a body or an object i.e the sum of all forces acting simultaneously on a body or an object.
Mathematically, net force is given by the formula;
Where;
- Fapp is the applied force
- Fg is the force due to gravitation
Since the two force applied to the box are acting in opposite direction, we would subtract their values to find the net force.
Fnet = Fa - Fb
Fnet = 30 - 10
Fnet = 20 Newton
Answer:
Rutherford overturned Thomson's model in 1911 with his well-known gold foil experiment, in which he demonstrated that the atom has a tiny, high- mass nucleus. In his experiment, Rutherford observed that many alpha particles were deflected at small angles while others were reflected back to the alpha source.
Answer:sodium
Explanation: because its not hard to look on the PERIODIC TABLE
Answer:
A crystalline solid
Explanation:
Most solids form with a regular arrangement of their particles because the overall attractive interactions between particles are maximized, and the total intermolecular energy is minimized, when the particles pack in the most efficient manner. The regular arrangement at an atomic level is often reflected at a macroscopic level. Liquids dont use to have this kind of arrangements or shapes.
They produce oxygen and glucose.
Hope this helps :)
