Answer:
28.27 in²
Step-by-step explanation:
The area of a circle is dependent on only one variable: the radius:
A = πr²
If the radius is 3 inches, as you seem to indicate, then:
A = π(3 in)² = 9π in² = 28.27 in²
Answer:
a. 7.64 km/h
b. 6.0°
c. see below
Step-by-step explanation:
a) The total velocity of the boat is ...
7i +(0.6i +0.8j) = 7.6i +0.8j
The magnitude of this velocity is the speed of the boat, relative to land. That is given by the Pythagorean theorem.
|7.6i +0.8j| = √(7.6² +0.8²) = √58.4 ≈ 7.642 . . . . km/h
__
b) The angle of the total velocity with respect to the "i" direction (the direction of vector v) is ...
α = arctan(0.8/7.6) ≈ 6.009°
__
c) The boat is headed in a direction 6° different from its velocity relative to the water. That may need to be accounted for if the boat is traveling any significant distance.
Answer:
F= G m₁m₂/r²
a. F is directly proportional to the masses so any increase in the masses will increase the Force F and vice versa.
b. F is inversely proportional to the square of the distance between the masses so any increase in the distance will decrease the force F and vice versa.
c. G is a gravitational constant and is expressed in Nm²/kg². this will give force in Newtons
Answer:
the horizontal are called x-axis, while the vertical are called y-axis
