Answer:

(B) The world around you.

Explanation:

Science is an endeavor that does just that: asks questions about the world around us, and attempts to answer them, too. The questions it asks, when formulated precisely, are referred to as <em>hypotheses</em> (so the answer D is incorrect here). Scientists develop theories and observe natural laws (covered by choice C), design experiments and evaluate test results (choice A). But in the end, it is all about asking scientific questions about the world around you. The choice (B) is the best answer.

adell [148]

Answer:

4.9 eV .

Explanation:

It is the case of discharge through mercury tube light . In it , mercury atoms are exited due to which electrons are sent to higher energy level . Here current drops to zero because electrons are excited to higher level . Energy are absorbed in quantised manner . Energy absorbed by electrons will be 4.9 eV . That means , difference in energy between two energy level is 4.9 eV .

A book with mass 2.3 kg sits on a table. What is the normal force on the

natita [175]

Explanation:

The table is level and there are no other forces on the book, so the normal force is equal to the weight.

N = mg

N = (2.3 kg) (9.8 m/s²)

N = 22.5 N

WILL GIVE BRAINLIEST TO THE CORRECT ANSWER

LenKa [72]

Answer:

See the answers below.

Explanation:

We can solve both problems using Newton's second law, which tells us that the sum of forces on a body is equal to the product of mass by acceleration.

∑F =m*a

where:

F = force [N] (units of newtons)

m = mass = 1000 [kg]

a = acceleration = 3 [m/s²]

$F = 1000*3\\F=3000[N]$

And the weight of any body can be calculated by means of the mass product by gravitational acceleration.

$W=m*g\\W=1000*9.81\\W=9810 [N]$
