Answer:
You're supposed to measure the distance from X to the end of vector 5 using the appropriate scale, and measure the angle (counterclockwise from X) using a protractor.
Mathematically:
x = [83cos90+55cos141+69cos229+41cos281+61co... cm = -27 cm
y = [83sin90+55sin141+69sin229+41sin281+61si... cm = 55 cm
so d = √(x² + y²) = 61 cm
and Θ = arctan(55/-27) = -64º +180º (to get into QII) = 116º
Explanation:
Answer:
energy
Explanation:
waves can move distances without transferring any matter, so the answer is energy
Answer:
The Answer is C: incomplete dominance because the offspring display an intermediate form of tail length.
Answer:
8.5 kg
Explanation:
Angular momentum is conserved.
I₁ ω₁ = I₂ ω₂
I ω₀ = (I + mr²) ω
(49 kg m²) (40 rpm) = (49 kg m² + m (1.2 m)²) (32 rpm)
61.25 kg m² = 49 kg m² + (1.44 m²) m
m = 8.5 kg
The mass of the clay is 8.5 kg.
Answer: Its answer C: A wheelbarrow is more difficult to move as More objects are placed inside.
Explanation: The greater the mass of the object the more force is needed to make it move.
Hope this helps!! :)
