Answer
given,
watermelon blown into three pieces
two pieces of mass m
both pieces speed = v = 31 m/s
mass of third piece = 3 m
using conservation of mass
velocity of third component
angle
Electrical energy is a particle that moves through a wire and transferred into homes, work, etc to make electricity work in objects.
The common value for “Speed of light in vacuum” is metre per second.
Answer: Option b
<u>Solution:
</u>
Speed of light can be defined as the speed with which light waves propagate in different medium. In vacuum, speed of light is 186,282 miles per second or 299,792 km/s which is rounded off as .
“Speed of light in vacuum” is a universal constant and usually represented by ‘c’. Light waves travels at a speed of metre per second in vacuum.
Answer:
the ratio of the number of turns in the primary and secondary coils.

Answer:
1/3 times.
Explanation:
Let V₀ be the peak voltage .
IR ( rms ) = ( V₀ / √2 R )
R is value of resistance
IC = ( V₀ ωC / √2 )
( 1 / ωC is reactance of capacitance in ac circuit )
=
When frequency is tripled angular frequency will also be tripled
hence the ratio becomes 1/3 times.
