Nabr is the answer bcoz in a chemical reaction reactants react to form new substances and according to your options NaBr should be the answer
One way is the both have magnetic fields.
The distance that the rubber ducks traveled = 1600 miles.
The time taken to travel this distance = 10 months.
By definition, the approximate average speed of the ocean is
v = (1600 miles)/(10 months)
Note that
1 mile = 1609 m
10 months = (10 months)*(30 days/month) *(24 hours/day)
= 7200 hours (approx.)
= 7200*3600 = 2.592 x 10⁷ s
Therefore

Also,

Answer:
The average velocity is approximately 0.1 m/s, or 0.222 m/h.
Answer: B. The gravitational field strength of Planet X is Wx/m.
Explanation:
Weight is a force, and as we know by the second Newton's law:
F = m*a
Force equals mass times acceleration.
Then if the weight is:
Wx, and the mass is m, we have the equation:
Wx = m*a
Where in this case, a is the gravitational field strength.
Then, isolating a in that equation we get:
Wx/m = a
Then the correct option is:
B. The gravitational field strength of Planet X is Wx/m.
Answer:
the answer is 27
Explanation:
1/2mv^2 = KE
if mass is 3, and velocity is 3 (3^2 = 9)
then KE increases by a factor of 27
