It means that there's something else besides speed that contributes to reaction distance. So even when speed is zero, reaction distance is still not zero.
Answer:
34.70 N
Explanation:
Given :
F~ 1 = 43 N in direction 38◦
F~ 2 = 26 N in direction −140◦
F~ 3 = 27 N in direction 110◦
Therefore,
F~x = 43 cos (38) + 26 cos (-140) + 27 cos (110)
= 43 (0.7) + 26 (-0.7) + 27 (-0.3)
= 3.8
F~y = 43 sin (38) + 26 sin (-140) + 27 sin (110)
= 43 (0.6) + 26 (-0.6) + 27 (0.9)
= 34.5
so, F~ = 
= 34.70 N
Scientists could explore Europa’s oceans by using potent technologically advanced telescopes capable of deciphering the content beneath the ice crust.
<h3>What are potent technologically advanced telescopes?</h3>
The latest technologically advanced telescopes are potent optical devices that allow us to discover the presence of certain compounds not only in the atmosphere of other planets in the solar system but also the content on the surface (e.g, the water content).
These telescopes contain curved mirrors that gather and focus different spectra of light from the sky such as the Webb telescope which was launched by NASA in the final of 2021.
Therefore, with this data, we can see that technologically advanced telescopes are potent optical instruments that can be used to observe the presence of different compounds including water on the surface of a planet or its satellites such as in the case of Europe which is a satellite of Jupiter.

Answer:
Mass of the skater, m = 72.75 kg
Explanation:
It is given that,
Radius of the circular path, r = 31 m
Speed of the skater, v = 14 m/s
Centripetal force, F = 460 N
We need to find the mass of the skater. It can be determined using the formula of centripetal force. It is given by :
m = 72.75 kg
So, the mass of the skater is 72.75 kg. Hence, this is the required solution.
Answer:
H = 1/2 g t^2 no original vertical velocity
t = (2 * 2000 / 9.8)^1/2 = 20.2 s
Sx = 100 m/s * 20.2 s = 2020 m
