Correct Answer: D. number of times the stock is turned over

Correct Answer: A. 59°

Explanation

Cos \(\theta\) = \(\frac{4(12) + (-5)(3)}{\sqrt{12^2 + (-5)^2}\sqrt{4^2 + 3^2}}\)

Cos\(\theta\) = \(\frac{48 - 15}{(\sqrt{189})(\sqrt{25})}\)

\(\theta = cos^{-1}\) (\(\frac{33}{61.28}\))

\(\theta\) = cos\(^{-1}\)0.5367

\(\theta\) = 59\(^o\)

Correct Answer: B. killed Goliath, the Philistine giant

Correct Answer: A) caudal vertebrae support the tail and provide attachment for tail muscles

Explanation

This Biology question is asking about the function of different groups of mammalian vertebrae. The question wants to know which statement is not correct. Mammalian vertebrae are bones that make up the backbone or spine. The backbone is divided into different regions. Each region has a different function. The caudal vertebrae are found at the end of the backbone. They are also known as the tail vertebrae. The caudal vertebrae support the tail and provide attachment for tail muscles. Option A is correct. The thoracic vertebrae are located in the chest region. They articulate with the ribs to form a protective cage around the heart and lungs. Option B is correct. The lumbar vertebrae are in the lower back region. They are larger and stronger than the other vertebrae. The lumbar vertebrae provide attachment for abdominal muscles. Option C is correct. The sacral vertebrae are located below the lumbar vertebrae. They are fused together to form a triangular bone called the sacrum. The sacrum provides a strong foundation for the pelvis. It does not support the skull or allow nodding and rotating movement. Option D is incorrect. Therefore, the correct answer is option D. To learn more about this, please read the relevant sections of the recommended textbooks.

Correct Answer: D. 9cm

Explanation

From \(V = \frac{1}{3}\pi r^2 h. \hspace{1mm} r =\frac{14}{2}\\

462 = \frac{1}{3} \times \frac{22}{7} \times 7^2 \times h \\

h = \frac{3 \times 462}{22 \times 7}\\ h = 9\)

Correct Answer: A. increase in velocity at equal time intervals

Correct Answer: A. hydrogen chloride

Explanation

a) A collision between reactants may not produce new species because the reactants may the activation energy.

(b) AlCl\(_{3(g)}\) + H\(_2\)O\(_{(l)}\) \(\to\) Al(OH)\(_{3(aq)}\) + HCl\(_{(aq)}\) of the two products of aluminium chloride HCl is a strong acid which will make the medium acidic.
