Answer:
The speed of the boat-A is 47.84 knots.
Explanation:
Mass of boat-A = m
Mass of boat-B = m
Kinetic energy if the boat-A = E
Kinetic energy if the boat-B = E'
Velocity of boat-A = v = ?
Velocity of boat-B = v'= 34 knots = 34 nautical miles /hour
1 knot = 1 nautical mile per hour
1 nautical mile = 6,076 feet
34 nautical miles /hour = 34 nautical miles /hour × 6,076 ft/miles = 205,564 ft/hour
Kinetic energy of boat-A is given by :
Kinetic energy of boat-A is given by :
..[1]
Kinetic energy of boat-B is given by :
..[2]
E= 2E' (given)
[1] ÷ [2]
v' = 47.84 knots
The speed of the boat-A is 47.84 knots.
The answer is 2. Temperate.
Explanation:
Given parameters:
Dimension = 8.5in²
we are to convert from in² to cm²
in² = in x in
cm² = cm x cm
1 in = 2.54cm
Using dimensional analysis;
8.5in² x 
= 54.84cm²
We solved this problem using dimensional analysis where we multiplied the unit with 1.

You can't calculate the electronegativity difference of a single molecule you'll need a frame of reference to explain the electronegativity difference and properties arising due to the difference. Another term arise here is modified electronegativity that is calculated within the molecule between two atoms of different electronegativity and use to explain the nature of molecule wether they are electron withdrawing group or electron donating group and also used to compare the electronegativity with other molecule!
