As the temperature changes and their masses are the same, heat lost by the balls is directly proportional to their specific heat values. The heat lost by the aluminum ball is higher implies aluminum has higher specific heat.
Answer:
im sorry im just testing dont report please
Explanation:
please im begging you
True
Why? Back then there were relative horse species which evolves to the horse breeds we have now. Changes in food source, predators and Environment changed the horse.
Hope this helps
Answer:
The size of the mirror must be half of the size of your face.
Explanation:
As we know that pocket mirror is a plane mirror, for the plane mirror, distance of a person from the mirror does not affect the image formed by mirror. But the height of the mirror must be half of the height of the person to see the whole face. It is because pocket mirror is between your head and the virtual image formed, to see the virtual image, your face rays must strike the reflecting surface, for that purpose the size of the mirror must be large enough so that your face rays can strike the reflecting surface easily.

The uniform purely axial magnetic induction required by the experiment in a volume large enough to accommodate the Lorentz Tube is produced by the Helmholtz Coils. What is the magnetic induction due to a coil current 1.5 Ampere? Convert the result in the still popular non-SI unit Gauss (1 Tesla = 10^4 Gauss).
B = N*mue*I/(2*r)
# of loops = 140
radius of the coil = 0.14m
Answer:
The magnetic induction is 
Explanation:
From the question we are told that
The coil current is 
The number of loops is 
The magnetic field due to the current is mathematically represented as
is the permeability of free space with value 
substituting value
From question
(1 Tesla = 
).
