Answer:
<em>The speed of the 8-ball is 2.125 m/s after the collision.</em>
Explanation:
<u>Law Of Conservation Of Linear Momentum</u>
The total momentum of a system of masses is conserved unless an external force is applied. The formula for the momentum of a body with mass m and velocity v is
P=mv
If we have a system of masses, then the total momentum is the sum of them all
If a collision occurs, the velocities change to v' and the final momentum is:
In a system of two masses, the law of conservation of linear momentum takes the form:
The m1=0.16 Kg 8-ball is initially at rest v1=0. It is hit by an m2=0.17 Kg cue ball that was moving at v2=2 m/s.
After the collision, the cue ball remains at rest v2'=0. It's required to find the final speed v1' after the collision.
The last equation is solved for v1':
The speed of the 8-ball is 2.125 m/s after the collision.
Buoyant force is equal to the weight of the total amount of liquid displaced by an object when submerged partially or completely in the fluid. This means that if an object that has a volume of 2m³ has 50% (1m³) of its volume submerged in water, the buoyant force will be equal to the weight of 1 m³ of water, this is about 1000kg.
With this in mind, the buoyant force will be equal to the weight of the amount of fluid that has the same total volume as the object when the object is completely submerged, this is to say, it has its total volume under the fluid.
<h3>
Answer:</h3>
AgCl + NaNO₃
<h3>
Explanation:</h3>
- The reaction between silver nitrate and sodium chloride is an example of a double displacement reaction.
- In a double displacement reaction compounds or salts reacts and exchange cations or anions to form new compounds or salts.
- In this case, silver nitrate and sodium chloride exchange anions and cations to form silver chloride and sodium nitrate.
- Therefore, the complete reaction is given by;
AgNO3 + NaCl → AgCl + NaNO₃
- But since silver chloride is a precipitate, the reaction may also be an example of a precipitation reaction.
