Answer:
5.31143691523 m/s²
Explanation:
m = Mass = 280 g
x = Displacement of spring = 21.7 cm
Time period

Angular velocity is given by


From Hooke's law

The acceleration due to gravity on the planet is 5.31143691523 m/s²
Yes, I have been able to satisfy my curiosity.
 
        
             
        
        
        
The data convincingly show that wave frequency does not affect wave speed. An increase in wave frequency caused a decrease in wavelength while the wave speed remained constant. The last three trials involved the same procedure with a different rope tension.

Answer:
147.456077993 Hz
Explanation:
 = Frequency of the sonar = 22 kHz
 = Frequency of the sonar = 22 kHz
 = Velocity of the whale = 4.95 m/s
 = Velocity of the whale = 4.95 m/s
v = Speed of sound in water = 1482 m/s
The difference in frequency is given by

The difference in frequency is 147.456077993 Hz
 
        
             
        
        
        
To increase the force required to move an object without change mass is : To increase the acceleration of the object 
<h3>Force acting on an object </h3>
Given that Force = Mass * acceleration 
An increase in the acceleration of an object in motion will result in a proportional increase in the Force required to move the object becasue force of an object is directly proportional to the acceleration of an object. 
Hence we can conclude that To increase the force required to move an object without change mass is To increase the acceleration of the object.
