Answer:

Y, X, Z, W

Explanation:

Jerome must put the given models in the order Y, X, Z, W to display the development of atom from the earliest to the most recent one. 'Y' represents 'Thomson's plum pudding model' came in 1904 which was followed by the 'Rutherford's nuclear atomic model' of 1911 as represented by X. This was succeeded by the 'Bohr's electrostatic model' in 1913(as shown in model Z) and lastly, the model W which exemplifies the 'Quantum Mechanical Model' by Edwin Schordinger in 1926. Thus, the correct order is <u>Y, X, Z, W</u>.

When a body of mass 0.25 kg is attached to a vertical massless spring, it is extended 5.0 cm from its unstretched length of 4.0
lora16 [44]

Answer:

d=0.165m

Explanation:

Given

m=0.25kg,x_{1}=5cm*\frac{1m}{100cm}=0.05m,x_{2}=4cm*\frac{1m}{100cm}=0.04m,v=2\frac{rev}{s}

The tension of the spring is

F_{k}=K*x_{1}=m*g

K=\frac{m*g}{x_{1}}

K=\frac{0.25kg*9.8m/s^2}{0.05m}=49N/m

The force in the spring is equal to centripetal force so

F_{c}=\frac{m*v^2}{r}

v=w*r=2\pi*r

But Fc is also

Fc=KxΔr

F_{c}=K*(r-x_{2})

Replacing

m*4\pi^2*r=K*(r-x_{2})

0.25kg*4\pi^2*r=49*(r-0.04m)

r=0.205m

total distance is

d=0.205-0.04=0.165m
