Convert the following temperatures to degrees Celsius or Fahrenheit: (a) 95°F, the temperature on a hot summer day; (b) 12°F,
Elis [28]

Answer:

a) 35°C, the temperature on a hot summer day

b) -11.11°C, the temperature on a cold winter day

c)  a 38.88°C fever

d) a furnace operating at 1011.11°C

e) 523.67°F ( theoretically the lowest attainable temperature )

Explanation:

  • °C = ( °F - 32 ) / 1.8
  • °F = ( 1.8 * °C ) +32

a) 95°F ⇒ °C = ( 95 - 32 ) / 1.8 = 35°C

b) 12°F ⇒ °C = ( 12 - 32 ) / 1.8 = -11.11°C

c) 102°F ⇒ °C = ( 102 -32 ) / 1.8 = 38.88°C

d) 1852°F ⇒ °C = ( 1852 -32 ) / 1.8 = 1011.11°C

e) 273.15°C ⇒ °F = ( 1.8 * 273.15 ) + 32 = 523.67°F

A particle accelerates from rest with an acceleration of 8.0m/s2. Calculate its velocity after 150s. What kinematic formula must
Ipatiy [6.2K]

<u>Answer</u>:

Final velocity: 1200 m/s

<u>Explanation</u>:

Formula:   \overline{a} = \frac{v - v_0}{t} = \frac{\Delta v}{\Delta t}

<u>Where</u>:

a = average acceleration

v = final velocity

vo = starting velocity

t = elapsed time

<em>Here the final velocity is unknown which we have to find. The initial is 0 m/s</em>

<em>as it was at rest. The time taken: 150 seconds. Acceleration given 8.0 m/s²</em>

using the formula:

\overline{a} = \frac{v - v_0}{t}

8 = \frac{v - 0}{150}

v = 1200 m/s

What is the concentration of the hydroxide ion? Given that the concentration of the hydronium ion is 2.3 X 10^-7 M
professor190 [17]

Answer:

4.35 * 10^-8 M

Explanation:

Since the concentration of the hydronium ion= 2.3 X 10^-7 M

And we know that;

[H3O^+] [OH^-] = 1 * 10^-14

[H3O^+]  = concentration of the hydronium ion

[OH^-] = concentration of the hydroxide ion

So;

[OH^-] =1 * 10^-14/[ H3O^+]

But [H3O^+] = 2.3 X 10^-7 M

[OH^-] = 1 * 10^-14/2.3 X 10^-7

[OH^-] = 4.35 * 10^-8 M
