Physics
1 answer:
kotykmax [81]3 years ago
8 0

Answer:

1)  

sinA=5/13       sinB=12/13

cosA= 12/13   cosB=5/13

tgA=5/12      tgB=12/5

2)

sinA=8/17       sinB=15/17

cosA= 15/17   cosB=8/17

tgA=8/15      tgB=15/8

3)

sinA=7/25       sinB=24/25

cosA= 24/25   cosB=7/25

tgA=7/24      tgB=24/7

4)

sinA=1/2       sinB=√3 /2

cosA= √3 /2   cosB=1/2

tgA=1/√3       tgB=√3  

5)

sinA=1/√2       sinB=1/√2

cosA= 1/√2   cosB=1/√2

tgA=1       tgB=1

GaryK [48]

Distillation

Explanation:

The name of the process used to refine oil into different products is called distillation. A refinery has huge distillation columns where is separated into its different fractions.

  • Distillation is a separation technique in which a mixture such as crude oil is separated into its fractions.
  • The components of the mixture must have an appreciable boiling point difference.
  • After distillation, oil is separated into difference components such as heavy oil, natural gas, kerosene, gasoline e.t.c.
  • The liquid with the least boiling point rises up in the column first and is collected.

A force of 10 N causes a spring to extend by 20 mm. Find a) the spring constant of the spring in N/m b) the extension of the spr
suter [353]

(a) The spring constant is 500 N/m.

(b) The extension of the spring when 25 N force is applied is 0.05 m.

(c) The applied force to cause an extension of 5 mm is 2.5 N.

The given parameters:

  • Applied force, F = 10 N
  • Extension of the spring, x = 20 mm

The spring constant is calculated as follows;

F = kx\\\\k = \frac{F}{x} \\\\k = \frac{10}{20 \times 10^{-3}} \\\\k = 500 \ N/m

The extension of the spring when 25 N force is applied is calculated as follows;

F = kx\\\\x = \frac{F}{k} \\\\x = \frac{25}{500} \\\\x = 0.05 \ m

The applied force to cause an extension of 5 mm is calculated as follows;

F = kx\\\\F = 500 \times 5 \times 10^{-3}\\\\F = 2.5 \ N
