Answer:
Explanation:
Let assume that system is conservative. From application of the Principle of Energy Conservation, it is noticed that initial linear kinetic energy must be equal to the gravitational energy at the top of the circle. That is to say:
Where .
Answer:
Chlorine and Fluorine
Explanation:
When you look at our descriptions of the elements fluorine and chlorine, you will see that they both have seven electrons in their outer shell. That seven-electron trait applies to all of the halogens. They are all just one electron shy of having full shells.
Newton's First Law states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force.
Momentum = (mass) x (velocity)
Original momentum before the hit =
(0.16 kg) x (38 m/s) this way <==
= 6.08 kg-m/s this way <==
Momentum after the hit =
(0.16) x (44 m/s) that way ==>
= 7.04 kg-m/s that way ==>
Change in momentum = (6.08 + 7.04) = 13.12 kg-m/s that way ==> .
-----------------------------------------------
Change in momentum = impulse.
Impulse = (force) x (time the force lasted)
13.12 kg-m/s = (force) x (0.002 sec)
(13.12 kg-m/s) / (0.002 sec) = Force
6,560 kg-m/s² = 6,560 Newtons = Force

Answer:
The show with 20 N force will accelerate more than the show with 10 N force, because 20 N force is greater than 10 N force.
Explanation:
From Newton's second law of motion, acceleration is the ratio of applied to mass of the object.
Acceleration is directly proportional to an applied force. At a constant mass, acceleration increases with an increase in the applied force.
Therefore, the show with 20 N force will accelerate more than the show with 10 N force, because 20 N force is greater than 10 N force.
