Answer:
2.5
Explanation:
density = mass/volume
density = 45gram/18cm cubed
density = 2.5
I THINK IT'S 2.5
Answer:
Explanation:
energy for photon is calculated in same wasy as for electromagnetic radiation
energy for electromagnetic radiation = hf
where f is the frequency of photon
h is Planck's constant = h = 4.14 × 10−15 eV · s.
thus
energy of photon = 4.14 × 10−15 eV · s * 2.36 x 10-19 Hz
energy of photon = 9.77 * 10−(-15+ -19) eV
energy of photon = 9.77 * 10−34eV answer
Answer:
C:to the right side of the periodic table, and it is given
the suffix -ide.
Explanation:
Given that,
Volume of a hallow glass sphere is 350 mL
Specific gravity is 1.252
We need to find the weight of the sphere. The ratio of density of substance to the density of water is called specific gravity.
The density of water is 1 g/mL
We know that,
1 pound = 453.592 grams
So,
m = 0.97 lbs
So, the weight of the sphere is 0.97 lbs or 0.97 pounds.
