Your answer is. D. 10÷60 = 1.66km/hr
        
             
        
        
        
Answer:
 The velocity ( ) of the wave is 3.08
) of the wave is 3.08  .
.
Explanation:
According to the figure, the distance ( ) between a trough and its adjacent crest is
) between a trough and its adjacent crest is  . Also the wavelength (
. Also the wavelength ( ) of the wave is
) of the wave is  . Pepe and Alfredo count 11 crests to pass the raft in
. Pepe and Alfredo count 11 crests to pass the raft in  = 21.5 s.
 = 21.5 s.
So, the time period ( ) of oscillation of the wave is
) of oscillation of the wave is

So, the velocity ( ) of the wave is
) of the wave is

Answer:
Electric field on proton 

Explanation:
Given that

We know that
Charge on proton

We know that 
Force = Electric field x Charge
F= E x q



Electric field on proton
