Answer:
hide on a place where there is no windows take a radio
Explanation:
K.E = 1/2*m*v^2 = 1/2(500)(3)^2 = 2250 J
m*g*h = 500(9.8)(30) = 147000 J
2250 + 147000 = 149250
The answer to this is: a molecule
Answer: in this question, the only charge in the cavity is Q. Inside the conducting spherical shell, the electric field is zero.
While outside the shell, the electric field is given by: k(q + Q)/r²
Where;
K= is a constant which is given as, 8.99 x 10^9 N m² / C².
Q= source charge which creates the electric field
q= is the test charge which is used to measure the strength of the electric field at a given location.
r= is the radius
Explanation: Inside the conducting spherical shell, the electric field is zero since the Electric field vanishes everywhere inside the volume of a good conductor.
Answer

Explanation:
given,
Side of square coil = 3.2 cm
Number of turns = 2720
magnetic field in the coil increases to = 0.45 T
time interval = 1.7 s
average induced voltage in the coil = ?
length = 0.032 m
Area = 0.032² = 0.001024 m²
induced voltage


The average voltage induced in the coil is equal to
