Answer:
As the launch force increase the launch velocity will
<em><u>Increase</u></em>
The reason for your answer to number six is because
<em><u>There is a direct relationship between force and acceleration.</u></em>
<em><u /></em>
Explanation:
<em>It is known all over the place that, there is a direct relationship between Force and acceleration of an object leading to an increase in force being directly proportional to the increase in the acceleration of the given object and vice versa.</em>
 
        
             
        
        
        
Answer: Velocity can best be described as, the speed in a given direction.
Explanation: To find the answer, we need to know more about the Velocity of a body.
<h3>What is Velocity of a body?</h3>
- Velocity is the rate of change of displacement.
- It's a vector quantity and is measured in m/s.
- It can be positive, negative or zero.
- A body is said to be in uniform motion, then its velocity remains constant.
- Change in velocity can be a change in speed.
- The magnitude of velocity is less than or equal to speed.
Thus, we can conclude that, the option C is best describing velocity.

The charge present determines a force to be attractive or repulsive.
The charges acquired by two bodies determines the Force as Attractive Or Repulsive.
Electric Force applied due to Electrical charges is same in magnitude but opposite in direction. This corresponds this phenomenon equivalent to the Newton's Third Law.
Examples of the experiments and observations:
- On combing hair through a comb and then keeping it close to small pieces of paper shows attraction of paper pieces towards the comb.
This occurs due to the Electric charges present in the comb that induces charge in paper pieces leading to their attraction.
- In both Gravitational Force and Coulomb force, the force remains inversely proportional to the square of the distance following the Inverse Square Law being the Central Force system. This only differs by the fact that in Gravitational Force, masses are used and in Coulomb force, charges are used.
The more the distance between the charges, the less is the Electric Force.
The lesser the distance between the charges, the more is the Electric Force.
If both the objects are charged the same i.e. either positive or negative then the Force is Repulsive and if the charges are Oppositely charged then the force is attractive.
Hence, the charge present determines a force to be attractive or repulsive.

The ration of the rms speed of 235uf6 to that of 238uf6 is 1.004.
The molecular mass of 235uf6 is 349, while that of 238uf6 is 352.
The rms speed is calculated as
v=√(3RT/m)
Thus the ratio rms speed of 235uf6 to 238uf6 is calculated as
r=√(352/349)=1.004
 
        
             
        
        
        
Answer:
-6112.26  J
Explanation:
The initial kinetic energy,  is given by
 is given by
 } where m is the mass of a body and
} where m is the mass of a body and  is the initial velocity
 is the initial velocity
The final kinetic energy,  is given by
 is given by
 where
 where  is the final velocity
 is the final velocity
Change in kinetic energy,  is given by
 is given by

Since the skater finally comes to rest, the final velocity is zero. Substituting 0 for  and 12.6 m/s for
 and 12.6 m/s for  and 77 Kg for m we obtain
 and 77 Kg for m we obtain

From work energy theorem, work done by a force is equal to the change in kinetic energy hence for this case work done equals <u>-6112.26  J</u>
