Un tren parte de la ciudad A, a las 8 h. con una velocidad de 50 km/h, para llegar a la ciudad B a las 10 h. Allí permanece dura

Answer:T = 0.03 Nm.

d = 1.5 in = 0.04 m

r = d/2 = 0.02 m

P = 56 kips = 56 x 6.89 = 386.11 MPa

σ = 42 ksi = 42 x 6.89 = 289.58 MPa

To find Torque = T =?

Solution:σ = (P x r) / T

Thus, T = (P x r) / σ

Calculating T = (386.11 x 0.02) / 289.58

results in T = 0.03 Nm.

Response: Liquids conform to the shape of their container, yet they maintain a specific volume. Similarly, gases adjust their shape based on their container, but the volume of a gas is variable depending on the containment it occupies.

Explanation:

Response: The intensity of the magnetic field generated by the wire stands at 5.56 × 10^-6 T

Clarification: Kindly refer to the attachments provided below

Answer: The correct choice is (d)

Explanation:

This analysis assumes that the heat supplied by the hot body matches the heat absorbed by the cold body.

where,

= the specific heat capacity of copper =

= the specific heat capacity of water =

= the mass of copper = 120 g

= the mass of water = 300 g

= the final temperature of the mixture =

= the initial temperature of copper =?

= the initial temperature of water =  

Using the provided values in the equation yields:

Thus, the temperature of the kiln is approximately

Answer:

The increase in pressure within the engine block of the car amounts to 1782.18 ATM.

Explanation:

Provided:

the volume change of water, ΔV = 9%

the bulk modulus for ice, K = 2 x 10⁹ N/m²

It is calculated using the bulk modulus formula;

so when the water freezes, the pressure increase in the automobile engine block is;

Thus, the final pressure increase inside the automobile engine block is 1782.18 ATM.
