It most likely wont explode right away but the fumes from the heated pickle might put you on a mild high if you breathe it in a lot...
Answer:
first lens v = 48 cm
second lens v = -15.6 cm
magnification = 1.67
final image is virtual
and final image is upright
Explanation:
given data
distance = 16 cm
focal length f1 = 12 cm
focal length f2 = 10.0 cm
to find out
location of the final image and magnification and Type of image
solution
we apply here lens formula that is
1/f = 1/v + 1/u .....................1
put here all value and find v for 1st lens
1/12 = 1/v + 1/16
v = 48 cm
and find v for 2nd lens
here u = 20- 48 = -28
- 1/10 = 1/v - 1/28
v = -15.6 cm
and
magnification = first lens (v/u) × second lens ( v/u)
magnification = (-15.6/-28) × ( 48/16)
magnification = 1.67
so here final image is virtual
and final image is upright
Answer:
58.32 N
Explanation:
Area of a circle = 
where r is the radius of the circle.
The cylinder has a radius of 0.02 m, its area is;
=
= 
x 
= x 0.0004
= 1.2571 x 
Area of the cylinder is 0.0013 
.
The safety valve has a radius of 0.0075 m, its area is;
=
= x 
= x 5.625 x 
= 1.7679 x 
Area of the valve is 0.00018 .
From Hooke's law, the force on the safety valve can be determined by;
F = ke
= 950 x 0.0085
= 8.075 N
Minimum force, 
, required can be determined by;
= 
= 
= 
= 58.32
The minimum force that must be exerted on the piston is 58.32 N.
