Hydrogen cyanide (HCN) is a product of combustion that:
bekas [8.4K]

b. is equally as toxic as carbon monoxide (CO).

Explanation:

Hydrogen Cyanide is a product of combustion that is equally as toxic as carbon monoxide CO.

The gas is a product of combustion in blast furnances, coke ovens, e.t.c

  • Just like carbon monoxide, they are blood agents that are toxic in the body
  • Prolonged exposure to hydrogen cyanide can lead to death eventually.
  • The gas is a able to produce cyanide ion that seriously impacts the process of cellular respiration and bringing it to a halt.
  • It is listed as one of the dangerous chemical weapons.

using hooke's law, f spring = k triangle x, find the elastic constant of a spring that stretches 2 cm when a 4 newton force is a
Ksivusya [100]

As we know that spring force is given as

F = kx

here we know that

F = 4 N

x = 2 cm = 0.02 m

now from the above equation we will have

4 = k(0.02)

k = 200 N/m

so the elastic constant of the spring will be 200 N/m

You need to make a spring scale to measure the mass of objects hung from it. You want each 2.1 cm length along the scale to corr
Gennadij [26K]

Answer:

46.67 N/m

Explanation:

mass, m = 0.1 kg

distance, y = 2.1 cm = 0.021 m

Let K be the spring constant.

F = mg = Ky

0.1 x 9.8 = K x 0.021

K = 46.67 N/m

Thus, the spring constant of the spring is 46.67 N/m.
