Answer:81.235N
Explanation:
Work=88J
theta=10°
distance=1.1 meters
work=force x cos(theta) x distance 
88=force x cos10 x 1.1 cos10=0.9848
88=force x 0.9848 x 1.1
88=force x 1.08328
Divide both sides by 1.08328
88/1.08328=(force x 1.08328)/1.08328
81.235=force
Force=81.235
 
        
             
        
        
        
Answer:
Bulk modulus = 1.35 ×  Pa
 Pa 
Explanation:
given data 
density = 1400 kg/m³
frequency = 370 Hz
wavelength = 8.40 m
solution
we get here bulk modulus of the liquid that is 
we know Bulk Modulus =  ...............
   ...............
here  is density i.e 1400 kg/m³
 is density i.e 1400 kg/m³ 
and v is =  frequency × wavelength 
v = 370 × 8.40 = 3108 m/s
so here bulk modulus will be as
Bulk modulus = 3108² × 1400 
Bulk modulus = 1.35 ×  Pa
 Pa
