Answer:
17.46° W of N
Explanation:
His prow must point westward so that the westward component of his total velocity is equal to the eastward river speed.
3 = 10sinθ
sinθ = 3/10
θ = 17.4576... or about 17.46° W of N
it will take him 5 / 10cos17.46 = 0.52414... hrs. or about 31 min 27 s to cross.
C. Gamma rays have more energy than infrared rays
Answer:
The resistance is
.
Explanation:
Given that,
Power = 259 kV
Current = 429 A
Resistance 
We need to calculate the current in each insulator
Using formula of current

Put the value into the formula


So all 95 insulators are in parallel
We need to calculate the resistance
Using formula of resistance

Put the value into the formula




Hence, The resistance is
.
The answer would be B ok man good luck
I hope this helps!
Friction<span> is the resistance to motion of one object moving relative to another. It is not a fundamental force, like gravity or electromagnetism. Instead, scientists believe it is the result of the electromagnetic attraction between charged particles in two touching surfaces.
Hope this is of great help to you, and happy studying~!
