Answer:
Witch Doctor
Song by Ross Bagdasarian Sr.
Explanation:
I instantly thought of Alvin and the Chipmunks!
I would select A. Nitrogen due to the fact Nitrogen is found in most soil samples and Aluminum and mercury are metals. Also, limestone i don't find beneficial to plants whatsoever.
Answer: Angle formed with height and hypotenuse is 40 degrees
Explanation:
Hi, to answer this question we have to analyze the information given:
Since the triangle is a right triangle it has a right angle that has a value 90 degrees.
Since the sum of the interior angles is equal to 180 degrees:
180 = x +50 + 90
Solving for x:
180-90-50 =x
40° =x

The percentage of annual US government spending allocated to foreign aid is; 1 percent.
<h3>What was the US foreign aid?</h3>
Foreign aid refers to the international movement of money, services, or goods from governments or international institutions for the benefit of the receiving country or its citizens. Foreign aid can be fiscal, military, or humanitarian and is considered one of the significant sources of foreign exchange.
Now, A poll conducted by World Public Opinion in 2010 on the US public found out that the average estimate for how much of the government's budget is spent on foreign aid was 25 percent. The average amount proposed by the public was 10 percent of the federal government's budget be used on foreign aid. However, in actual terms, less than 1 percent of the US federal budget goes towards foreign aid.
Thus, we can conclude that the percentage of annual US government spending allocated to foreign aid is 1 percent.

The acceleration of the pendulum mass D is; r"_d = [x''(t) + lθ'' cos θ - lθ'² sin θ]i - l[θ'' sin θ - θ'² cos θ]j
<h3>What is Kinematics of particles?</h3>
Kinematics is the study of the geometry of motion of particles, rigid bodies, etc., disregarding the forces associated with these motions. However, Kinematics of a particle is the motion of a point in space.
From the sample problem, we can solve it using the (x, y, z) coordinate system to get;
r_c = x(t) i
r_d = [x(t) + l sin θ]i + l cos θ j
Finding the first derivative of r_d gives velocity as;
r'_d = [x'(t) + lθ' cos θ]i - lθ' sin θ j
Taking the second derivative of r_d gives the acceleration as;
r"_d = [x''(t) + lθ'' cos θ - lθ'² sin θ]i - l[θ'' sin θ - θ'² cos θ]j
A sample problem of kinematics of particles is;
A block C slides along the horizontal rod, while a pendulum attached to the block can swing in the vertical plane. Find the acceleration of
the pendulum mass D.
