The main purpose of the turbine in the turbojet engine is to
AnnZ [28]
<span>The correct answer is A. drive the compressor. It's not D because the compressor compresses it, not the turbine. The temperature and the velocity of gasses are unrelated to this. There are in fact two turbines, and the first one gets power from exhaustion, which is then used to power to turbine in the turbojet that is used to drive the compressor. This is how turbojets commonly work.</span>

When the mass is removed, the length of the cable is found to be l0 = 4.76 m. After the mass is added, the length is remeasured
ElenaW [278]

Answer:

1242337 N/m^2

Explanation:

The cross section area of the cable is

A = \pi r^2 = \pi * 0.025^2 = 0.002 m^2

Let g = 9.81m/s2. The stress acting on the cable when mass is added is

\sigma = F/A = mg/A = 35*9.81/0.002 = 174867 Pa

The strain when the cable is stretched from 4.76 to 5.43 m is

\epsilon = \frac{\Delta L}{L} = \frac{5.43 - 4.76}{4.76} = 0.14

So the young modulus of the cable is

E = \sigma / \epsilon = 174867 / 0.14 = 1242337 Pa = 1242337 N/m^2

Which describes an atom that has fewer neutrons than protons and more electrons than protons?
aleksklad [387]

Answer:

negative ion

Explanation:

An atom that has fewer neutrons than protons and more electrons than protons is a negative ion.

The positively charged particles in an atom are the protons

The negatively charged particles in an atom are the electrons.

  The charge an atom carries depends on the balance between the number of protons and electrons in an atom.

  • When the number of protons is more than the number of electrons, the atom is positively charged.
  • When the number of electrons is more than the number of protons, the atom is negatively charged.

How many neutrons are needed to initiate the fission reaction shown?
nalin [4]

Answer: One neutron

Explanation:

one neutron 1/0n

Sum up the mass numbers on the right 99 + 135 + 2 = 236.

The sum of the mass numbers on the left should equal 236. 235 + 1 = 236
