Education QUESTION #10891

Question 7344

Who is recognised as the founder of discovery learning?

Bruner✔️
Jean Piaget
J.S. Mill
Gardner

Correct Answer Logic:

Jerome Bruner (1915–2016) is the founder of discovery learning — the educational theory that students learn best by actively discovering knowledge through exploration and experimentation rather than passively receiving it. Bruner's concept of the spiral curriculum and his 1961 book The Process of Education established discovery learning. While Piaget's constructivism influenced Bruner, Bruner is specifically credited with developing and promoting discovery learning as a pedagogical approach.

Chemistry QUESTION #1089

Question 7345

The ratio of wavelengths of light absorbed by hydrogen atom for $n=2\to n=3$ and $n=4\to n=6$ transitions is:

$\dfrac{1}{9}$
$\dfrac{1}{4}$✔️
$\dfrac{1}{36}$
$\dfrac{1}{16}$

Correct Answer Logic:

For hydrogen: $\frac{1}{\lambda} = R_H\left(\frac{1}{n_1^2}-\frac{1}{n_2^2}\right)$. Transition 1 ($n=2\to3$): $\frac{1}{\lambda_1}=R_H\left(\frac{1}{4}-\frac{1}{9}\right)=R_H\cdot\frac{5}{36}$. Transition 2 ($n=4\to6$): $\frac{1}{\lambda_2}=R_H\left(\frac{1}{16}-\frac{1}{36}\right)=R_H\cdot\frac{5}{144}$. Ratio: $\frac{\lambda_1}{\lambda_2}=\frac{5/144}{5/36}=\frac{36}{144}=\frac{1}{4}$.

Question 7346

Considering enzyme action minimum temperature is:

0°C✔️
100°C
37°C
45°C

Correct Answer Logic:

At 0°C (or near freezing), enzyme activity approaches its minimum because the very low thermal energy provides insufficient kinetic energy for enzyme-substrate collisions and conformational changes. While enzymes are not denatured at 0°C (they are merely inactive), this represents the practical lower temperature boundary for enzymatic reactions.

Correct Answer Logic:

Gentrification involves private capital reinvestment rehabilitating deteriorating inner-city neighborhoods, increasing property values, attracting higher-income residents, and displacing original lower-income inhabitants through rising rents and property taxes.

Question 7349

In a pea plant, seed color is determined by two alleles: Y (Yellow, dominant) and y (green, recessive). Which parental cross would result in a 1:1 ratio of yellow to green seeds?

$Yy \times YY$
$Yy \times yy$✔️
$Yy \times Yy$
$YY \times yy$

Correct Answer Logic:

A test cross $Yy \times yy$ gives 50% $Yy$ (yellow) and 50% $yy$ (green), resulting in a $1:1$ ratio. This is the classic test cross used to determine genotype.

Question 7355

The polar moment of area $J_O$ about point O is related to second moments $I_x$ and $I_y$ by:

$J_O = I_x - I_y$
$J_O = I_x + I_y$✔️
$J_O = \sqrt{I_x^2 + I_y^2}$
$J_O = I_x \cdot I_y$

Correct Answer Logic:

By the perpendicular axis theorem: $J_O=\int r^2\,dA=\int(x^2+y^2)\,dA=I_x+I_y$. This applies to planar areas.

Constitutional Law QUESTION #5816

Question 7359

The federal government grants a state \$10 billion for highway construction, but only on the condition that the state raises its minimum drinking age to 21. The state challenges this as unconstitutional 'coercion' under the Tenth Amendment. Is the condition valid?

No, because it is not related to the purpose of the grant.
No, because it is 'unduly coercive' under the Sebelius standard.
Yes, because it is clearly stated, relates to the federal interest in safe highways, and is not 'unduly coercive.'✔️
Yes, because Congress has absolute power to condition any federal funds for any reason.

Correct Answer Logic:

Under South Dakota v. Dole, Congress may use the spending power to 'encourage' states as long as: 1) it’s for the general welfare, 2) conditions are unambiguous, 3) it relates to a federal program/interest, and 4) it’s not 'coercive' (usually meaning it doesn't represent a massive percentage of the state's entire budget).

Mathematics QUESTION #7465

Question 7360

A man is walking towards a vertical pillar in a straight path, at a uniform speed. At a certain point A on the path, he observes that the angle of elevation of the top of the pillar is 30°. After walking for 10 minutes from A in the same direction, at a point B, he observes that the angle of elevation of the top of the pillar is 60°. Then the time taken (in minutes) by him, from B to reach the pillar, is:

10
20
5✔️
6

Correct Answer Logic:

Let the height of pillar be $h$ and the man's speed be $v$. Let distances from pillar be $d_A$ at A and $d_B$ at B. From angles: $\tan 30° = \frac{h}{d_A}$ gives $d_A = h\sqrt{3}$, and $\tan 60° = \frac{h}{d_B}$ gives $d_B = \frac{h}{\sqrt{3}}$. Distance AB = $d_A - d_B = h\sqrt{3} - \frac{h}{\sqrt{3}} = \frac{3h-h}{\sqrt{3}} = \frac{2h}{\sqrt{3}}$. Time for AB is 10 minutes, so $v = \frac{2h}{\sqrt{3} \cdot 10} = \frac{h}{5\sqrt{3}}$. Time from B to pillar = $\frac{d_B}{v} = \frac{h/\sqrt{3}}{h/(5\sqrt{3})} = 5$ minutes.
