Answer: the angle between the resultant vector and the vector of the 18 pound is 28°
Explanation:
given that data in the question; as its interpreted in the diagram below;
from the cosine rule, we know that;
a² = b² + c² - 2bc
so
(13)² = (6)² + (18)² - (2 × 6 × 18 ) cos∅
169 = 36 + 324 - 216cos∅
169 = 360 - 216cos∅
216cos∅ = 360 - 169
216cos∅ = 191
cos∅ = 0.8842
∅ = cos⁻¹ ( 0.8842 )
∅ = 27.8° ≈ 28° {nearest whole number}
Therefore the angle between the resultant vector and the vector of the 18 pound is 28°
Nothing. Absolutely nothing. Sometimes jealous, envy can have a play into this or they may think you’re a bit intimidating so they can’t really approach you. If you’re closed off and distant this may be a factor. But overall, you don’t need to seek the attention of others in order to be ‘good’ or ‘appealing’. Just do your own thing and don’t worry about others !!
Answer:
This is because it has more coils around the ferromagnetic material. increasing the number of coils increases the surface area in which the metal interacts with the current in the coil. This enables more atoms in the metal to become aligned hence becoming more magnetized.

Answer:0.07 rad/s
Explanation:
Given
kite is 100 ft high
and moves horizontally at 7 ft/s
Total string let out =200 ft
String length(l), vertical(y) & Horizontal(x) distance of kite will form a right angle triangle
Differentiating both side
Now
