Answer:
The correct solution is "1.2 m".
Explanation:
The given values are:
Wavelength of waves,
λ = 1.5 m
Speed of waves on surface,
V = 2 m/sec
Speed of waves in water,
V₁ = 1.6 m/sec
As we know,
⇒ 
or,
⇒ 
On substituting the values, we get
⇒ 
⇒ 
hence,
⇒ 
On substituting the values, we get
⇒

Answer:
on there boat there will two main forces act 1,upthrust which comes from water and air and other side on the plane air and gravity.
Explanation:
Average speed= total distance/total time =12km/h
The answer to this question is d because prejudices is not based on experience or reasons
Answer: Magnitude of electric field = 6.77×10^11N/C
Explanation: Electric field= E =KQ/ r ^2
Given:
Total charge Q=53.2nc
Radius 84cm= 0.84m
Coulombs constant K= 8.987x10^9NmC^-1
E =(( 8.987×10^9) × 53.2) /(0.84^2)
E = ( 4 . 777 ×10 ^ 9 )/ 0.7056
E = 6.77 × 10^ 11 NC^-1
