Answer:
Magnitude of the force is 4350N
Explanation:
As the woman accelerates at a distance of 22 m to go from rest to 62.5 m / s, we can use the kinematics to find the acceleration
v² = v₀² + 2 a x
v₀ = 0
a = v² / 2x
a = 62.5²/(2 × 22)
a = 88.78m/s²
the time you need to get this speed
v = v₀ + a t
t = v / a
t = 62.5 / 88.78
t = 0.704s
Let's caculate the magnitude of the force
F = ma
= 49 × 88.78
= 4350.22
≅ 4350N
Magnitude of the force is 4350N
t = 1,025 s
a = 55.43 m / s²
Because it changes what the substance is and creates a new substance.
lake effect snow is the correct answer
Answer: d = 2,079 m
Explanation:
5.5 m/s(6.3 min)(60 s/min) = 2,079 m
<h3><u>Technology used by astronomers to look for life on other plants:</u></h3>
- Space-based Hubble and Spitzer telescopes and Green Bank telescopes are used.
- Many new satellites are launched to trace earth like planets. Even the telescopes are carried by spacecrafts.
- Astronomers are using Allen Telescope Array that comprises 42 radio antennas to get hold of signals over a wide range of radio frequencies that are tuned to listen to the regions nearer to the red dwarf star constellations.
- Scientists needed telescopes that are capable of detecting planets like Earth in our planet’s neighborhood and see if any biological signatures connected to any microbial or other intelligent life can be found.
- Radio signals are also being used to detect if the outside world has something to communicate so that they can be detected.
