Answer:
A
Explanation:
occurs when a magnetic feild and an elctric conductor move relative to one another
<u>Answer:
</u>
Earth convection occurs at the mantle layer
<u>Explanation:
</u>
The movement of less dense material above the more dense material is called as convection. The mantle is the layer that lies between the core and the crust of the earth. The mantle is composed of rocks containing silicon, magnesium, oxygen, aluminium, iron and other minerals.
The heat energy of the core is transmitted to the rock in the lower mantle. This makes the rock with less temperature that lies in upper mantle to move down slowly. Now the rocks that are pushed up is eventually cooled and again pushed down by the hotter rock from the lower mantle. This is called as convection in earth’s mantle .

answer: No charge of the length of the bonds expected because the rod did not touch the charge source ( option A )
Explanation:
When the Charge is first, Furthest away and second and closest to the source charge. <em>The spring like bonds can be said to have No charge of the length of the bonds expected because the rod did not touch the charge source </em><em>when Furthest away the bond with charge will be less effective </em>
Answer:
4.5 m/s
Explanation:
so, you just divide the displacement or distance (202.5) by the time given (45)
202.5 ÷ 45 =4.5
Answer:
Point motion will eventually stops due to action of g exactly perpendicular...
Explanation:
If ignoring the air resistance, the magnitude of gravitational acceleration is already strong enough to stops the acceleration. As we know that, the spring constant of a bungee spring cord will be F = -k/x, where x is the stretched length and k is the spring constant of bungee cord. If F = ma = w = mg, the g = -m k/x. Now we can clearly see that the value of g remains constant due to the fluctuating length of the cord as the motion progresses back and forth in SHM say from x1 to x2 and x2 to x1.
