Answer:
<em>85.12 μAmp</em>
<em></em>
Explanation:
The battery power output = 17.15 Amp-hr
If the battery is to last 23 years, we have to calculate how many hours there are in 23 years
in one year there are 24 hours x 365 day = 8760 hrs
in 23 years there are 23 x 8760 = 201480 hours
maximum current to be drawn from the battery = (17.15 Amp-hr) ÷ (201480 hours) = 85.12 x 10^-6 Amp = <em>85.12 μA</em>
Answer:
The diffraction grating separates light into colors as the light passes through the many fine slits of the grating. This is a transmission grating. ... The prism separates light into colors because each color passes through the prism at a different speed and angle.
You multiply the high length and width and if your using centimeters then divide by 500 and then there's your answer.hoped this helped.
The rate of change of velocity with respect to time is acceleration. When we have some period of time, mathematically we write it: a=Δv/Δt, where Δv is a change in velocity and Δt is a time interval. When we talk about an instant of time, we have a limit: a=lim Δv/Δt, where Δt→0 and we write that as a=dv/dt where dv is an infinitesimal or infinitely small change in velocity and dt is an infinitesimally or infinitely small change in the time interval. So the correct answer is: the rate the velocity is changing at a given instant is acceleration.
The average speed in the first case is 19.86 m/s and the average speed in the second case is 13.67 m/s.
The formula of average speed is
average speed = total distance / total time
In first case
total distance is 143 km which is also 143000 m
and total time is 2 hours which is also 7200 seconds
so average speed = ( 143000 / 7200 ) m/s
average speed = 19.86 m/s
In second case
total distance is 160 km which is also 160000 m
and total time is 3 hours and 15 minutes which is also 11700 seconds
so average speed = ( 160000 / 11700 ) m/s
average speed = 13.67 m/s
So to conclude with we have find the the average speed in both cases by dividing total distance by total time and in first case we have got our answer as 19.86 m/s and in second case we have got 13.67 m/s.
