Answer: A) Transformer
Explanation: A Transformer is an apparatus, device or a component in a system that is used to convert high voltage into low voltage. It is used to either increase or decrease the voltage of an alternating current.
A transformer uses the basic principle of electro magnetic induction, having two or more coils, the voltage is changed from one coil to another but with thesame frequency as alternating current energy passes through them.
I'm pretty sure the answer is the gravitational pull increases
Answer:
It is number two
Explanation:
beacause a star cluster is a bunch of stars held together by gravity
Answer:
option A
Explanation:
given,
travel distance = 1 mm
diffusion constant for the molecule of oxygen in water = 1 x 10⁻⁹ m²/s
we know that
t is the time taken for diffusion
x = 1 mm = 10⁻³ m
D is the diffusion
t = 500 s
so, the option to the answer is 170 s
the correct answer is option A
