Answer: 68.4 s
Explanation:
The plot points seem to indicate a 5 m/s increase in velocity in the 6 seconds between 2 and 8 second marks. This makes the acceleration
a = 5 / 6 m/s/s
At time zero, the velocity is 13 m/s, so we need to increase by
70 - 13 = 57 m/s
t = v/a = 57 / (5/6) = 68.4 s
<u>Answer</u>:
Speed = 3.33 m/s
<u>Explanation</u>:
Formula:
Speed = distance / time
<em>Here distance is 800 metres and time is 240 seconds</em>
<em>Using the formula:</em>
Speed = 800 / 240
Speed = 3.33 m/s
Answer:
e = 30 V
Explanation:
given,
N = 30 turns
Area = 0.25 m²
angular speed = ω = 100 rad/s
Magnetic field = 0.04 T
maximum induced emf in the loop = ?
e = N B A ω
e = 30 x 0.04 x 0.25 x 100
e = 30 V
hence, the maximum emf induced in the loop is equal to e = 30 V
Based on the time that the solar system takes to circle the center of the milky way, the length of time that the Tyrannosaurus rex dinosaurs lived is 0.291 galactic years ago.
<h3>How long ago did the Tyrannosaurus rex live?</h3>
The Tyrannosaurus rex lived 67 million years ago.
If a single galactic year is 230 million years then the Tyrannosaurus rex lived:
= Number of years ago Tyrannosaurus rex lived / Number of years in galactic years
Solving gives:
= 67 / 230
= 0.291 galactic years ago
Full question is:
Galactic years. The time the Solar System takes to circle around the center of the Milky Way galaxy, a galactic year, is about 230My. In galactic years, how long ago did the Tyrannosaurus rex dinosaurs live?
