Answer:
1.2 x 
N
Explanation:
The centripetal force of a body moving in a circle is given by:
Centripetal force = 
where M = mass of the object, v = velocity with which the object is moving, and r = radius of the circle.
In this case, M = 25,000 kg, v = 2.0 m/s, and r = 8.2 m. Hence;
Centripetal force generated by the whale = 25,000 x 2^2/8.2
= 12,195.12 N = 1.2 x N to two significant digits.
Answer:
D. Resultant Vector
Explanation:
By definition, adding 2 vectors gives a resultant vector
I would say the answer is B. That's what makes the most sense to me but I'm not certain.
Answer:
C) 2
Explanation:
The amount of centimeters is about 2.5 centimeters in an inch
Some of such commonly used compounds are Sodium Chloride, Nitric Acid, Sulphuric Acid, Sodium Acetate, Chloric acid, etc. The first battery was invented by Italian physicist Alessandro Volta in the year 1799 by generating continuous electric current using voltaic piles.
