Answer:
Heat capacity or thermal capacity is a physical property of matter, defined as the amount of heat to be supplied to a given mass of a material to produce a unit change in its temperature. The SI unit of heat capacity is joule per kelvin. Heat capacity is an extensive property
Answer:
The apparent weight of the object is 0.465 N.
Explanation:
Given that,
Weight = 0.71 N
Water level = 50 mL
object inserted = 75 mL
We need to calculate the volume of solid
Using formula of volume
We need to calculate the buoyancy force
Using formula of buoyancy force
Put the value into the formula
We need to calculate the apparent weight of the object
Using formula of apparent weight
Put the value into the formula
Hence, The apparent weight of the object is 0.465 N.
Answer:
A) Elements are placed in teh same group because they have similar properties. B) Every element in a family of elements has similar atomic numbers as the others in its family. C) Alkali Metals
Explanation:
The acceleration of gravity on Earth is 9.8 m/s² downward.
This means that gravity adds 9.8 m/s downward to the speed
of a freely falling object every second.
So after 25 sec, it's falling (25 x 9.8m/s) = 245 m/s faster than
it was falling at the beginning of the 25 seconds.
If it dropped from rest (no speed), then its velocity
after 25 seconds is 245 m/s downward.
Answer:
v = 2.51 x 10⁸ m/s
Explanation:
1.00sin62.7 = nsin48.1
n = 1.19
v = c/n = 3.00e8/1.19 = 2.51e8 m/s
