Answer
<em><u>density of mercury is 13.6 g/ml and that 1 lb = 0.45 kg</u></em><em><u>.</u></em>
The resultant magnitude and direction of the vectors are as follows:
- A. A = 6.6; θ = 30.8° from the x-axis
- B. B = 10.4; θ = 196.7° from the x-axis
- C. C = 23.3; θ = 300° from the x-axis
- D. D = 40.4; θ = 138° from the x-axis
- E. E = 49.5; θ = 346° from the x-axis
<h3>What is the resultant magnitude and direction of the given vectors?</h3>
The resultant magnitude and direction of the vectors are as follows:
A. A = √(5.7² + 3.4²)
A = 6.6
θ = tan⁻¹(3.4/5.7)
θ = 30.8° from the x-axis
B. B = √{(-10)² + (-3²)}
B 10.4
θ = tan⁻¹(3/10) + 180
θ = 16.7° + 180°
θ = 196.7° from the x-axis
C. C = √{(12)² + (-20²)}
C = 23.3
θ = 360° - tan⁻¹(20/12)
θ = 300° from the x-axis
D. D = √{(-30)² + (27²)}
D = 40.4
θ = 180 - tan⁻¹(27/30)
θ = 138° from the x-axis
E. E = √{(48)² + (12²)}
E = 49.5
θ = 360° - tan⁻¹(12/48)
θ = 346° from the x-axis
In conclusion, the resultant of the vectors and direction are obtained using the resultant vector formula.

If there is no friction, then NO force is needed to keep an object moving. Go back and look at Newton's first law of motion again.
Answer:
5.832 g/h
Explanation:
We can find the rate of mass relative to time by taking the derivative of M
We can plug in the current length x = 6 cm and current length rate 0.03 cm/h
