<span>When reading a buret, the initial reading should be taken from the top of the glassware and the final volume should still taken at the top. If the buret is completely, the initial volume for most buret would be zero. though, there are some where their initial starts at 50 decreasing to zero.</span>
The block is made of A) Tin, as its specific heat capacity is 
Explanation:
When an amount of energy Q is supplied to a sample of material of mass m, the temperature of the material increases by 
, according to the following equation
:
where 
is the specific heat capacity of the material.
In this problem, we have:
m = 2 kg = 2000 g is the mass of the unknown material
is the amount of energy supplied to the block
is the change in temperature of the material
Solving the equation for , we can find the specific heat capacity of the unknown sample:
And by comparing with tabular values, we can find that this value is approximately the specific heat capacity of tin.

What Kepler's constant ? ? ! ?
The only constant in Kepler's laws is in the third one, where it says something to the
effect that (square of a body's period) / (cube of its distance from the central body)
is a constant.
That means it's a constant for multiple little ones orbiting the same central body.
But it's not the same constant for other central bodies.
It's one constant for the planets, asteroids, and comets orbiting the sun.
It's a different constant for the moon, TV satellites, weather satellites,
and military satellites orbiting the Earth.
The magnitude of the resultant is
√ (22² + 2.2²) = √ (484 + 4.84) = √488.84 = 22.11 m/s .
The direction of the resultant is
tan⁻¹(22N / 2.2E) = tan⁻¹(10) = 5.71° east of north .
