Yes,because when you touch water or gets on you what do you feel it wet right? therefore water is wet

So I would say (a) water isn't always wet; wetness is always relative to a given substance and/or type of surface and (b) as to why it is wet when it is, presumably the answer is in terms of surface tension.

A 9,900 kg object feels a gravitational force of 12 N due to a 52,000 kg object. What is the distance between the
aleksley [76]

Answer:

0.05 m

Explanation:

From the question given above, the following data were obtained:

Mass of first object (M1) = 9900 kg

Gravitational force (F) = 12 N

Mass of second object (M2) = 52000 kg

Distance apart (r) =?

Gravitational constant (G) = 6.67×10¯¹¹ Nm²/Kg²

Thus, we can obtain the distance between the two objects as shown below:

F = GM1M2/r²

12 = 6.67×10¯¹¹ × 9900 × 52000 /r²

Cross multiply

12 × r² = 6.67×10¯¹¹ × 9900 × 52000

Divide both side by 12

r² = (6.67×10¯¹¹ × 9900 × 52000)/12

Take the square root of both side

r = √[(6.67×10¯¹¹ × 9900 × 52000)/12]

r = 0.05 m

Therefore, the distance between the two objects is 0.05 m

You want to launch a stone using the elastic band of a slingshot. The force that the elastic band applies to an object is given
Ksenya-84 [330]

Answer:

0.00288 J

Explanation:

We know that

W= Fds

F = −α∆s^4

α = 45 N/m^4 and ∆s = displacement

W= −α∆s^4ds

integrating both the sides from s= 0 to 0.2

W= 45/5×0.2^5= 0.00288 J
