True
The electromagnet will become stronger if we add more coils because there are more field lines in a loop then there is in a straight piece of wire. In a solenoid there are a lot of loops and they are concentrated in the middle, as more loops are added the field lines get larger, therefore making the electromagnet stronger.
Answer:
Is less in comparison with the rest of the Earth.
Explanation:
In poles now we have the magnetic centers of the planet, this will make that the magnetic field that is produced, can protect the planet from the radiation of cosmos. Magnetic field is also responsible of getting together the ionized particles that come from universe and they are ions, in this way they appear as an a boreal or austral aurora.
I'm pretty sure a violin produces a higher-pitched sound. I play the violin and it's pretty loud. (Hope this helps)
Answer:
The answer is
X: Converts mass into energy
Y: Is controlled by neutron absorption
Explanation:
To maintain a sustained controlled nuclear reaction (nuclear fission), for every 2 or 3 neutrons released, only one must be allowed to strike another uranium nucleus. If this ratio is less than one then the reaction will die out; if it is greater than one it will grow uncontrolled (an atomic explosion). A neutron absorbing element must be present to control the amount of free neutrons in the reaction space. Therefore, nuclear fission is controlled by neutron absorption.
Nuclear fission and fusion both converts mass to energy.
In both reactions total mass of material decreases but the energy comes out from atoms.
