Physics QUESTION #4388

A projectile is launched in air with a certain angle; its velocity is maximum at:

Point of projection✔️
Highest point
Between launching and highest point
At all points

Correct Answer Logic:

At the point of projection, the projectile has both horizontal and vertical components of velocity. At the highest point, only the horizontal component remains. Since speed is greatest at the launch point, velocity magnitude is maximum there.

Safety and security needs
Love and belonging needs

Maslow's Hierarchy of Needs (1943) is arranged as follows (bottom to top):

Physiological needs — food, water, shelter, air, warmth (FIRST priority)
Safety and security needs

MBBS QUESTION #10292

Question 2152

Conn's syndrome (primary hyperaldosteronism, typically from an adrenal adenoma) classically produces which combination of biochemical findings?

Hypertension, hypokalemia, and metabolic alkalosis, with suppressed plasma renin activity✔️
Hypotension with hyperkalemia
Elevated plasma renin with low aldosterone
Entirely normal electrolytes with isolated hypertension and no biochemical abnormality

Correct Answer Logic:

Autonomous aldosterone excess drives renal sodium retention (hypertension) with increased potassium and hydrogen ion excretion (hypokalemia and metabolic alkalosis); the resulting volume expansion suppresses renin-angiotensin activity, giving the classic biochemical triad plus low renin that distinguishes primary from secondary hyperaldosteronism.

Planning QUESTION #4976

Question 2153

In Net Present Value (NPV) calculation, if discount rate increases from 5% to 10%, the NPV will:

Increase
Decrease✔️
Remain constant
Double

Correct Answer Logic:

NPV formula $NPV = \sum_{t=0}^{n} \frac{C_t}{(1+r)^t}$ shows inverse relationship with discount rate $r$. Higher discount rate reduces present value of future cash flows, decreasing NPV. This reflects higher opportunity cost of capital.

Nursing QUESTION #9285

Question 2155

A patient develops pulmonary embolism (PE) post-surgery. Which of the following is the classic triad of symptoms?

Chest pain, fever, and bradycardia
Sudden dyspnea, chest pain, and hemoptysis✔️
Cough, wheezing, and hypotension
Fever, pleurisy, and tachycardia

The classic triad of Pulmonary Embolism (PE) — though present in only ~20% of cases — is:

Sudden dyspnea (most common presenting symptom)
Pleuritic chest pain (sharp, worsens on breathing)
Hemoptysis (blood-streaked sputum)

Other common signs of PE:

Tachycardia
Tachypnea (>20 breaths/min)
Decreased SpO₂
Anxiety and apprehension
Signs of DVT (calf pain, swelling) in ~50% of cases

Nursing priority: High Fowler's position, oxygen therapy, IV access, notify physician immediately, prepare for anticoagulation therapy (heparin). PE is the most preventable cause of post-operative death.

Heliophytes (sun plants) are plants adapted to grow in full, direct sunlight. They have structural adaptations such as smaller, thicker leaves with more palisade mesophyll layers and higher chlorophyll content to optimise photosynthesis in high-light conditions. Sciophytes are shade-tolerant plants; psamophytes grow in sandy soil environments.

Law QUESTION #9523

Question 2157

A trial Court tries a suit and passes a decree. An appeal is filed to the District Court which upholds the trial Court's decree. The losing party wants to challenge the District Court's decree. What is the next available remedy?

File a second appeal to the High Court on any ground
Directly petition the Supreme Court
File a review before the District Court
File a second appeal to the High Court on a substantial question of law only, under Section 100 CPC, since a second appeal on questions of fact alone is not maintainable✔️

Correct Answer Logic:

Section 100 CPC provides that a second appeal to the High Court lies only on a substantial question of law. Second appeals on pure questions of fact are not competent. The appellant must specifically formulate the substantial question of law at the time of filing.
