Explanation:
Newton's First Law ,
F = ma
a = m/F
a = 68 / 59
a = 1.15 m/s2
Answer:
mass
Explanation:
The mass only tells us the amount of a material. Density, melting points, and solubility are properties of a compound and will be different in this case.
EXPLANATION :
As per the question, the electron has jumped from ground state to higher energy level.
From Bohr's postulate, we know that electron can only move to higher excited state when the energy equivalent to excitation energy has been given to it. Otherwise, the electron can not move from ground state to the excited state.
Hence, it is obvious that the electron might have excited to higher energy level by providing sufficient energy from outside.
The external source might be light of suitable frequency or any electric or thermal source.

Explanation:
When you calculate the SLOPE of a line segment, what does the SLOPE represent? (Choose all that apply) the Distance traveled the Displacement the Velocity the Acceleration None of the above
The slope of any time graph can not give you distance or displacement except for position - time graph.
When you plot either distance or displacement against time, that is, distance time graph or displacement time graph, you can get speed or velocity as the slope of the line segment.
You can only acceleration as a slope in a line of best fit if velocity is plotted against time. That is, in a velocity time graph.
b. What is its period?
c. What is its frequency?
Answer:
a. 5 seconds
b. 5 seconds
c. 0.2 Hz
Explanation:
a) For 2 complete cycles, time taken is 10 s.
Thus, for 1 complete cycle, the pendulum would take = 10 s÷ 2 = 5 s
b) The time period of a pendulum can be defined as time to complete 1 cycle/oscillation. This is calculated in part a. Thus, time period of the pendulum is 5 s.
c) The frequency of a pendulum can be define number of cycles/oscillations in 1 s. It takes 5 s to complete 1 cycle.
In 1 s, number of cycles = (1 ÷ 5) s⁻¹ = 0.2 Hz.
