The correct answer is option A, 3.528 N

In this question the water has nothing to do, the gravity always pull the object with the same magnitude irrespective of the medium.

The force of gravity is calculated as

F=0.09*4000*9.8

=3.528 N

Force of gravity on the block in the water=3528 N. so option (A) is correct.

Explanation:

Force of gravity= mg

m= mass

g= acceleration due to gravity= 9.8 m/s²

mass m= volume x density

m=0.09 x 4000= 360 Kg

so force of gravity= 360 (9.8)

force of gravity=3528 N

scientific endeavor is a purely positive action that does not sometimes cause potentially harmful results.
Naya [18.7K]
I think that the question is simply asking whether the statement is correct.

The statement is wrong! The scientific endeavor (the work of the scientists, the pursue of knowledge) can be potentially harmful. For example, many tests of human medicine have to be performed on animals, and often the medicine causes great suffering in the animals (and gets rejected for testing on humans).
