The focal length will be = 2.67 cm

The distance between the convex lens or a concave mirror and the focal point of a lens or mirror is called the focal length. It is the point where parallel rays of light meet or converge.

given

u (object distance) = 260 cm

v (image distance) = 2.70 cm

f (focal length) = ?

using lens formula

1/f = 1/u + 1/v

    = 1/260 + 1/2.70

    = 2.67 cm

The focal length will be = 2.67 cm

How did Rutherford's experiments demonstrate that Thomson's model of the atom was incorrect?
chubhunter [2.5K]
Rutherford's Gold foil experiment involved the firing of atoms at a piece of gold foil only a few atoms thick. Rutherford expected that the particles would go straight through, but some were deflected. This experiment proved that atoms have a dense positively charged nucleus.

Answer: d. They showed that atoms have a dense nucleus.

Calculate the pressure on a man’s foot when a woman of mass 65 kg steps on his foot with her heel which has an area of 0.12m2 wi
tino4ka555 [31]

Answer:

Pressure = force/area

= 650N/0.12m^2

= 5416.7 to 1 d.p

I got 650N by taking the gravitational field on earth to be 10N/kg.

Weight = mass x gravitational field

= 65 x 10N/kg

= 650

Answer is 5416.7 pascals (Pa)

Or

5308.3 Pa

if gravitational field was taken to be 9.8N/kg

Hope this helps!
