<u>Answer</u>
Yes, the car reaches the door before the gate closes.
<u>Explanation</u>
The time taken by the car to reach at the door.
Time = distance / time
= 22/13
= 1.6923 seconds
Time taken by the door to close up to the height of the car.
Distance the door has to move to prevent the car from escaping = 9.1.4 = 7.6 m
From newton's 2nd law of motion;
s = ut + 1/2 gt²
7.6 = 0.6t + 1/2 × 10t²
7.6 = 0.6t + 5t²
50t² + 6t - 76 = 0
Solving this quadrilatic equation,
t = 28.537 seconds
Answer: Yes, the car reaches the door before the gate closes.
Answer:
a) Species change over time; some traits become more common, others less. This process of change is driven by natural selection. The traits that become more common are the ones that are “adaptive” or “increase fitness” (that is, a creature's chances of living longer and producing more offspring)
Explanation:
because it is
Answer:
<em>The distance of the light is 9.4608 x 10^25 m</em>
<em></em>
Explanation:
Time taken by the light = 10 billion years = 10 x 10^9 years
speed of light = 3 x 10^8 m/s
speed of light in m/years is = (3 x 10^8)/(60 x 60 x 24 x 365) = 9.4608 x 10^15 m/year
distance = speed x time
therefore, the distance of this light = 10 x 10^9 x 9.461 x 10^15 = <em>9.4608 x 10^25 m</em>
The most essential while choosing the privilege PFD for a traveler is the information required for choosing right PFD for the traveler's body weight and trunk size.Note that the offspring of what age under 8 years old are required to wear legitimately secured PFD while on vessel unless in securely closed cabin.
