Answer:

Temperature of the mixture=8 °C

Explanation:

Let, Temperature of the mixture=t °C

Q₁ = Q₂

=> m₁SΔΘ₁ = m₂SΔΘ₂

=> 39 × (20+t) = 21 × (60-t)

∴ t = 8 °C

A car takes 10 s to go from v = 0 m/s to v = 25 m/s at constant acceleration. If you wish to find the distance traveled using th
german

Initial velocity (u) = 0 m/s

Final velocity (v) = 25 m/s

time taken (t) = 10s

acceleration (a) = ?

Now,

Acceleration is rate of change of velocity, so formula is

a = (v - u)/t

a = (25 - 10)/10

a = 15/10

a = 1.5 m/(s^2)

Use this value of a.

What is the maximum frequency of visible light in hertz?
Nataliya [291]
All frequencies of light in hertz are in between
Red = 4 * 10 ^{14} Hz and
Violet = 8 * 10 ^{14} Hz

Light with a lower frequency than 4 * 10^14 Hz, are called infrared and can't be seen by human eye. Light with a higher frequency than 8 * 10^14 Hz, are called ultraviolet and can't bee seen by human eye. 

Therefore, the maximum frequency of visible light in Hz, is  8 * 10^14 Hz
