Answer:

Summer

Explanation:

The North Pole stays in full sunlight all day long throughout the entire summer (unless there are clouds), and this is the reason that the Arctic is called the land of the "Midnight Sun"

Answer:

Summer begins in the Northern Hemisphere on June 20 or 21 when the North Pole is tilted a full 23.5° toward the sun. On this day, the Northern Hemisphere has the most hours of daylight, while the Southern Hemisphere has the least hours of daylight.

Answer:

B) The iron

Explanation:

Both blocks have the same volume. Since the wood is partially submerged, it displaces a smaller volume of fluid than the iron, that is completely submerged. The buoyant force is proportional to the volume of the displaced fluid. Therefore, the buoyant force on iron is greater.

Answer:

Scientific evidence relies on data, and it is crucial for researchers to ensure that the data they collect is representative of the “true” situation. This means using proved or appropriate ways of collecting and analyzing the data and ensuring the research is conducted ethically and safely.

Answer:

$-2.60097\times 10^{-6}\ C$

Explanation:

k = Coulomb constant = $8.99\times 10^{9}\ Nm^2/C^2$

r = Distance between charges = 2 cm

The electric force is given by

$F=\dfrac{k4\times 10^{-6}q_A}{r^2}$

Also

$F=\dfrac{k4\times 10^{-6}q_B}{r^2}$

The sum of the force is given by

$\sum F=\dfrac{k4\times 10^{-6}q_A}{r^2}cos 30+\dfrac{k4\times 10^{-6}q_B}{r^2}cos 30\\\Rightarrow \sum F=2\dfrac{k4\times 10^{-6}q_A}{r^2}cos 30\\\Rightarrow q_a=\dfrac{\sum Fr^2}{2\times k4\times 10^{-6}cos30}\\\Rightarrow q_a=\dfrac{405\times 0.02^2}{2\times 8.99\times 10^9\times 4\times 10^{-6}cos30}\\\Rightarrow q_a=2.60097\times 10^{-6}\ C$
