Answer:
3.43 m
Explanation:
f = 100 mm
u = - 103 mm
Let v be the distance between the screen and the lens of the projector.
Use lens equation
1 / f = 1 / v - 1 / u
1 / 100 = 1 / v + 1 / 103
1 / v = 1 / 100 - 1 / 103
1 / v = (103 - 100) / (100 x 103)
1 / v = 3 / 10300
v = 3433.33 mm = 3.43 m
Answer:
for this problem, 2.5 = (5+2/2)-(5-2/2)erf (50×10-6m/2Dt)
It now becomes necessary to compute the diffusion coefficient at 750°C (1023 K) given that D0= 8.5 ×10-5m2/s and Qd= 202,100 J/mol.
we have D= D0exp( -Qd/RT)
=(8.5×105m2/s)exp(-202,100/8.31×1023)
= 4.03 ×10-15m2/s
Answer:

Explanation:
Induced EMF in the coil is given by the equation

so we have

also we know that rate of change in current in solenoid is given as

so induced EMF of coil is given as


now induced current in the coil will be given as



t=5s
it was correct on my do-now
so I hope it was useful for you
Answer:
90.77%
its capacity utilization rate for the month is 90.77%
Explanation:
The capacity utilisation rate can be expressed mathematically as;
Capacity utilisation rate = capacity used/Best operating level × 100%
Given;
Total Number of production time = 205hours
Production output/capacity used = 21400 units
Best operation rate = 115units/hour
Best operation output for the month of July( at best operation level )
=115units/hour × 205 hours = 23575 units
Capacity utilisation rate = 21400/23575 × 100%
= 90.77%
