Question

M=750г k=7H/m T,V -?

Answer 1

Буду считать то что задача по пружинный маятник

$Т = 2\pi \sqrt{ \frac{m}{k} }$

$Т = 2 \times 3.14 \sqrt{ \frac{0.75}{7} } = 2 \: (c)$

$w = \frac{2\pi}{Т}$

$w = \frac{2 \times 3.14}{2} = 3.14( \frac{рад}{c} )$

$v = \frac{1}{Т}$

$v = \frac{1}{2} = 0.5(c^{ - 1} )$

$v - частота$

Answer 2

It appears that you've provided variables and their respective values, but you haven't specified what you want to calculate or what equations or relationships you want to use. To provide a meaningful answer, I need more information or context about what you're trying to calculate or solve for.

Here are the variables you've provided:

• M (mass) = 750 grams (0.75 kilograms)
• k (specific heat) = 7 H/m (not a standard unit; please provide the specific units for specific heat)
• T (temperature) = ? (you haven't provided the initial or final temperature)
• V (volume) = ? (you haven't provided the volume)

If you can provide more context or details about the problem you're trying to solve or the specific equation or relationship you want to use, I'd be happy to help you further.
