Answer:
When the spring in the ballistic pendulum is compressed, <em>energy is stored up in the spring as potential energy. </em>When the steel ball is launched by the spring, <em>the stored up potential energy of the compressed spring is transformed and transferred into the kinetic energy of the steel ball as it flies off to hit its target. </em>On hitting the soft target, <em>some of the kinetic energy of the steel ball is transferred to the soft target (since they stick together), and they both start to swing together</em>. During the process of swinging, the system's energy is transformed between kinetic and potential energy. <em>At the maximum displacement of the ball from its point of rest, all the energy is converted to potential energy of the system</em>. <em>At the lowest point of travel (at the rest point), all the energy of the system is transformed into kinetic energy. </em>In between these two points, <em>energy the energy of the system is a combination of both kinetic and potential energy.</em>
In the end, all the energy will be transformed and lost as heat to the surrounding; due to the air resistance around; bringing the system to a halt.
False because nucleus just consists proton which is positively charged and neutron which is neutral. It does not contain electron , so nucleus only can be positive charge
D. ) Mercury ( Can fluctuate from -183 C to 427 C)
Hope this helps!
Answer:
distance is how much space is between, speed is how fast they are going, velocity is money and acceleration is going
Explanation:
Answer:
Only B is correct.
Explanation:
Electrolysis and galvanic activity are two different ways of the passage of electricity. Electrolysis occurs at a spontaneous reaction, and galvanic activity needs an external force to happen.
For example, a cell works by a redox reaction, in which a material reduces (gain electrons), and the other oxides (loses electrons). As higher is the standard reduction potential of a material, as easy is to it to reduces. Thus, if a cell works with the reduction happens with the material with low standard reduction potential, then it works by galvanic activity.
When electronics are connected to the house system, it's necessary to do the ground connection, which will allow the electrons that are dissipated to go to the earth. So, it is done incorrectly, the electrons flow to the equipment, which they natural path. So, the electrolysis can occur with a poor ground connection.
