The trip time taken by the box is 1.5 sec.
Explanation:
Given:
distance(d) = 30 m
Velocity(v) = 20 m/s
By using formula:
Velocity =
or, 20 =
or, time(t) =
∴ time (t) = 1.5 sec
Hence the the block took 1.5 sec to slide 30 m.
Answer:
14 hours 18 minutes.
Explanation:
ratio of number of orbits, so it completes 7 orbits in the time Janus does 6.
(16*60+41)*6/7=858 minutes or 14 hours 18 minutes
Answer:
Part A:
Part B:
Explanation:
Part A:
To calculate the number of free electrons n we use the following formula::
n=1.5N-Au
Where N-Au is number of gold atoms per cubic meter
So:
Part B:
n is calculated above which is 8.85*10^{28}m^{-3}
Charge on electron=1.602*10^{-19}
Elec- Conductivity= 4.3*10^{7}
Answer:
5,760
Explanation:
1 minute is equal to 60 seconds. so you will multiply 60 times 96. and that equals 5,760
