Answer:
Explanation:
When the pendulum falls freely the net acceleration due to gravity is zero.
As we know that the time period of simple pendulum is inversely proportional to the square root of acceleration due to gravity, thus the time period becomes infinity.
Energy at top = U = mgh = 40 * 9.8 * 12 = 4704 J
Energy at bottom = 1/2 mv² = 1/2 * 40 * 10² = 4000 / 2 = 2000 J
Energy Lost = Final - Initial = 4704 - 2000 = 2704 J
In short, Your Answer would be 2704 Joules
Hope this helps!
Answer:
A solenoid field is increased with the increase in the current flow through the coil.
Explanation:
A solenoid is a current carrying coil with a significant number of loops. It works like an electromagnet inside which, a uniform and strong magnetic field is created. The magnetic field outside the solenoid field is nearly zero but not exactly zero.
While experimenting with the solenoid, scientists came to know that the magnetic field generated by the solenoid increases with the increase in the current, flowing through the solenoid.
The magnetic field works strongly around the arena of coil. The field changes its direction only near the ends and gets weak. Else its uniform throughout the loops.
The magnetic field inside the solenoid can be formulated as,
Where,
B = Magnetic field generated by the solenoid
= Constant
I = Current flowing through the loops of the solenoid

Answer:
<u>Jupiter and Saturn</u>
Explanation:
Giant planets -
Giants planets have maximum moons ,
for example ,
Jupiter and Saturn .
Jupiter have 63 moons ( according to 2009 calculation ) , where , 8 moons are the regular satellites , 4 moons are spherical and large , 4 moons are small and close to Jupiter , in addition to it Jupiter have 55 irregular satellites .
Second highest moon is with planet Saturn , with 61 moons .
Many of moon's are thought to have been captured from the small-body population during the formation of the solar system .
