Low. Copper has relatively high conductivity.
Hence the period is 1 sec.
<u>Explanation</u>:
- If the time taken by a single pendulum is 0.25 seconds. Then a pendulum will move to two extreme positions from one mean position only. That will means that the total time period is given by
T = 2 
0.25 = 0.50 seconds.
- A pendulum will oscillate from mean to the extreme, then extreme to mean, then mean to the extreme and again extreme to mean, so it will cover 2 cycles.
Hence, 2 0.50 = 1.
Answer:
7.8 J/g °C
Explanation:
0.39 J/g °C x 200 J / 10g
= 7.8 J/g °C
Answer: 55m
Explanation:
Given the following :
Driving speed = 90km/hr
Inattentive period (time) = 2.2s
Distance during inattentive period =
(driving speed * time)
Converting driving speed from km/hr to m/s
1000m = 1km
3600s = 1hour
Therefore,
90km/hr = (90 * 1000) / 3600
90km/hr = (90000)/ 3600 = 25m/s
Therefore ;
Distance during inattentive period =
(driving speed * time)
Distance during inattentive period = (25m/s × 2.2s) = 55m
Distance traveled during inattentive period is 55m
All we really need to know to answer this one is the speed of sound, and that's not easy. Sound has different speeds in wet air, dry air, warm air, cool air, and air at high or low pressure ... and ALL of these are present on the way from the thunderstorm to you !
So let's just use the number for the speed of sound in dry air at sea level and comfortable temperature: 343 meters/sec.
time = (distance) / (speed)
Time = (1485 meters) / (343 m/s)
Time = (1485/343) second
Time = 4.3 seconds roughly approximately around about
