Answer:
26m/s²
Explanation:
Given parameters:
Mass of the student = 60kg
Weight = 1560N
Unknown:
Acceleration due to gravity = ?
Solution:
Weight is a force on a body due to gravity;
Weight = mass x gravity
Insert the given parameters and solve;
1560 = 60 x gravity
Gravity = = 26m/s²
Answer:
KO
Explanation:
Assuming those are weight percentages, we first convert to moles.
83 g K * (1 mol / 39 g) ≈ 2.128 mol K
17 g O * (1 mol / 8 g) ≈ 2.125 mol K
Normalize by dividing by the smallest:
2.128 / 2.125 ≈ 1.00
2.125 / 2.125 = 1.00
So the empirical formula is:
KO
Permanent... static means staying the same. (It remains this meaning in English, science, an math)

Explanation:
The energy of a single photon is given by:
where
E is the energy
h is the Planck constant
f is the frequency of the light
The light in our problem has a frequency
, so the energy of each photon of that light is:
