A mineshaft has an ore elevator hung from a single braided cable of diameter 2.5 cm. Young's modulus of the cable is 10×10^10N/m

2. When the cable is fully extended, the end of the cable is 900 m below the support. How much does the fully extended cable stretch when 1500 kg of ore is loaded? Express your answer with the appropriate unit

Answer:

ΔL = 0.2697 m = 26.97 cm

Explanation:

Given

∅ = 2.5 cm = 0.025 m

E = 10*10¹⁰ N/m²

L = 900 m

m = 1500 Kg

ΔL = ?

We get P = W as follows

W = m*g = (1500 Kg)(9.81 m/s²) =  14715 N

then we apply the equation of Hooke's Law

ΔL = P*L / (A*E)

⇒  ΔL = 14715 N*900 m / (π*0.25*(0.025 m)²*10*10¹⁰ N/m²)

⇒  ΔL = 0.2697 m = 26.97 cm

A cart moves along a track at a velocity of 3.5 cm/s. When a force is applied to the cart, its velocity increases to 8.2 cm/s. I
Lorico [155]

Answer:

3.13cm/s²

Explanation:

Given

Initial velocity u = 3.5cm/s

Final velocity v = 8.2cm/s

Time t = 1.5secs

Required

Acceleration of the cart a

To get that, we will use the equation of motion

v = u+at

Substitute the given parameters

8.2 = 3.5+1.5a

1.5a = 8.2-3.5

1.5a = 4.7

a = 4.7/1.5

a = 3.13cm/s²

Hence the acceleration to the cart is 3.13cm/s²

An ideal spring obeys hooke's law: f = −bikx. a mass of m = 0.3 kg hung vertically from this spring stretches the spring 0.13 m.
Anarel [89]
The force = 0.3 * 9.8 = 2.94
x = 0.13

k = 2.94/0.13
k = 22.6 N/m

What type of equipment do you need to play Curling? A broom and a stone A metal ball and a wooden ball A net and a rattan ball A
Nana76 [90]
I'm not super sure but, I would think it would be a broom and a stone. When you play curling you push a special 'curling stone' across a icy floor and special sweepers to reduce the fiction within the icy floor.
