On a roller coaster potential energy builds up while you are going up a hill . Once at the top all of that energy is being released this giving you a push which means all of that energy is making you down down the hill. Hope this helps you.

alexira [117]

Answer:

(a) hypermetropia

(b) convex lens

(c) 133.33 cm

(d) - 21.05 cm

Explanation:

(a) As she is old age, so she is suffering from hypermetropia.

(b) It is the defect due to which a person is not able to see the nearby objects clearly, so it is cured by convex lens of suitable focal length.

(c) Power, P = + 0.75 D

Focal length is the reciprocal of power of lens.

f = 1/ P = 1/0.75

f = 133.33 cm

(d) v = -25 cm, f = 133.3 cm

use lens equation

\frac{1}{f}=\frac{1}{v}-\frac{1}{u}

\frac{1}{133.3}=\frac{-1}{25}-\frac{1}{u}

\frac{-1}{u}=\frac{133.33+25}{133.33\times25}

u = - 21.05 cm

A spring with spring constant 31 N/m is attached to the ceiling, and a 4.5-cm-diameter, 1.5 kg metal cylinder is attached to its
aalyn [17]

Answer:

0.315758099469 m

Explanation:

m = Mass of cylinder = 1.5 kg

\rho = Density of water = 1000 kg/m³

V = Volume = Ah

A = Area = \pi r^2

k = Spring constant = 31 N/m

x = Displacement

g = Acceleration due to gravity = 9.81 m/s²

Here the forces are conserved

Weight of cylinder = Buoyant force + Spring force

mg=\rho Vg+kx\\\Rightarrow mg=\rho Ahg+kx\\\Rightarrow 1.5\times 9.81=1000\times \pi(2.25\times 10^{-2})^2x\times 9.81+31x\\\Rightarrow 1.5\times 9.81=46.60213x\\\Rightarrow x=\dfrac{1.5\times 9.81}{46.60213}\\\Rightarrow x=0.315758099469\ m

The length of the submerged cylinder is 0.315758099469 m
