Answer:
the formula of the compound formed when Beryllium reacts with the sulfate ion is BeSO4
Explanation:
the answer is 1.5 hope this helps
<span>We know that pressure is the force applied into a surface, in our case the wall of the room, so then first we will calculate the surface of this wall:
S = 2.2 * 3.2 = 7.04 m2
Then we also know the atmospheric pressure in normal conditions is 1 atm. That is the same 1 atm = 101325 Pascals or 101325 N/m2
Now we need to use the formula : P = F/S where P is pressure, F is force and S is surface to calculate the force:
F = P * S = 101325 * 7.04 = 713,328 Newtons
Conclusion: the force acts on the wall due the air inside the room is 713,328 N</span>
Answer:
The average force that the shooter must exert to prevent the weapon from moving is 21.7 Newtons.
Explanation:
m=33g=0,033kg
V= 342 m/seg
115 bullets/min= 1 bullet every 0.52 seconds.
By the principle of momentum and amount of movement we have to:
F*t=m*V
F= (m*V)/t
F= (0.033kg * 342 m/s) / 0.52 sec
F= 21.7 Newtons
