The answer is that it is lower because it is harder to get something to move than to make it continue moving due to molecular interactions and inertia.

Answer:
Infrasound vs. Ultrasound: Infrasound is sound that is below the lower limit of human hearing, below 20 Hz, and ultrasound is above the upper limit of human hearing, above 20,000 Hz. Individuals use infrasound - this recurrence run for checking seismic tremors and volcanoes, graphing rock and oil developments underneath the earth. Infrasound is described by a capacity to get around hindrances with little scattering.
For instance, a few creatures, for example, whales, elephants and giraffes convey utilizing infrasound over significant distances. Torrential slides, volcanoes, seismic tremors, sea waves, water falls and meteors produce infrasonic waves. Symptomatic ultrasound, additionally called sonography or demonstrative clinical sonography, is an imaging technique that utilizes high-recurrence sound waves to create pictures of structures inside your body. The pictures can give important data to diagnosing and treating an assortment of ailments and conditions.

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.
Answer:
Distance covered by B is 4 times distance covered by A
Explanation:
For an object in free fall starting from rest, the distance covered by the object in a time t is
where
s is the distance covered
g is the acceleration due to gravity
t is the time elapsed
In this problem:
- Object A falls through a distance during a time t, so the distance covered by object A is
- Object B falls through a distance during a time 2t, so the distance covered by object B is
So, the distance covered by object B is 4 times the distance covered by object A.
Answer:
D. 1.7
Explanation:
Refractive index can be calculated using the formula;
η =real depth/apparent depth
Assume the real depth to be-----x
Apparent depth will be : 40% less than real depth;
60/100 *x =0.6x
η = x/ 0.6 x
η = 1/0.6
η= 10/6
η = 1.66
η = 1.7
