When a perfume bottle is opened, some liquid changes to gas and the fragrance spreads around the room because gases do not have a definite volume.
Hope this helps!
Answer:
the maximum allowable current is 7302.967 amperl
Explanation:
The computation of the maximum allowable current is shown below;
Force F = mean ÷ 4π 2 I_1 I_2 ÷d × ΔL
200 N = (10)^-7 (2I × I) ÷ 0.08 × 1.5
200 = 3.75 × 10^-6 I^2
I = √200 ÷ √ 3.75 × 10^-6
= 7302.967 amperl
Hence, the maximum allowable current is 7302.967 amperl
Basically we applied the above formula
Answer:
efficiency of engine is 0.21
Explanation:
given:
Th=980 K
Tc=570 K
since efficiency of engine is given as:
n=3/5*n_m
=3/5(1-Tc/Th)
=0.21
efficiency of engine is 0.21
