Answer:
Wavelength = <u>1.5 m</u> 
Explanation:
The formula for waves in terms of wavelength, speed and frequency is:
Speed (v) = Frequency (f) × Wavelength (λ)
33 = 22 × λ
33 = 22λ 
λ = 
So, λ = 1.5 m 
 
        
             
        
        
        
From the choices provided, the better answer is ' T ' .

Answer: equal to 3 m/s
Explanation:
Speed of golf ball will be equal to 3 m/s because in Perfect Elastic Collision Energy is conserved .
So speed of golf ball will be same in order to Satisfy 
Initial Kinetic Energy =Final Kinetic Energy 
Considering Bowling ball remains at rest after collision other wise some energy will also be acquired by bowling ball which automatically decreases the amount of Kinetic Energy of golf ball resulting its speed to decrease by some extent.
