The force that accelerates a rocket in outer space is exerted on the rocket by the?

Physics

Nana76 [90]2 years ago
3 0

Gases at pressure are released by rockets as they travel towards space. According to Newton's third law, the combustion chamber's exhaust gases push the rocket with an accelerating force known as the thrust.

<h3>Explain exactly Newton's Third Law:</h3>

According to Newton's third law, if an object A pulls on an object B, then object B must exert an equal-sized and opposite-direction force on the first thing directed in the opposite direction. This law illustrates a symmetry in nature whereby forces always occur in pairs and whereby no body can exert a force without also being subjected to one.

<h3>What are Newton's 3rd law examples?</h3>

Action and response are always equal but always move in the opposite direction, according to Newton's third law of motion. A human walking on the ground, a hammer driving a nail, a magnet attracting a paper clip, and a horse pulling a cart are all examples of Newton's third rule of motion.

Compute the longitudinal strength of an aligned carbon fiber-epoxy matrix composite having a 0.25 volume fraction of fibers, ass
zmey [24]

Answer:

632.5 MPa

Explanation:

\sigma_{m} = Matrix stress at fiber failure = 10 MPa

V_f = Volume fraction of fiber = 0.25

\sigma_f = Fiber fracture strength = 2.5 GPa

The longitudinal strength of a composite is given by

\sigma_{cl}=\sigma_{m}(1-V_f)+\sigma_fV_f\\\Rightarrow \sigma_{cl}=10(1-0.25)+(2.5\times 10^3)\times 0.25\\\Rightarrow \sigma_{cl}=632.5\ MPa

The longitudinal strength of the aligned carbon fiber-epoxy matrix composite is 632.5 MPa

Restaurant owners agree to comply with state, but not federal, health
Charra [1.4K]

Answer:

False.

Explanation:

A public health license can be defined as series of privileges and authority granted to a practitioner in the public domain, to offer services to the general public after admitting to comply with the standards, rules and regulations set aside by health regulatory agencies and the government (both state and federal).

This ultimately implies that, all restaurant owners must have met the minimum requirements (criteria) and agree to comply with all the standards, rules and regulations with respect to public health before they are endorsed and then given a license to practice or operate by the appropriate agency or authorities.

Hence, restaurant owners agree to comply with state, federal, and health regulations when applying for a public health license.
