8 0

Answer:

Q = C M T        where C is the specific, M the mass, T the temperature change

Note 1 cal = 4.19 Joules

1562.75 J / (4.19 J/cal) = 378 cal

C = Q / (M * T) = 378 cal / (25.35 g * 155 deg C)

C = .096 cal / g deg C

A house is 54.0 ft long and 48 ft wide, and has 8.0-ft-high ceilings. What is the volume of the interior of the house in cubic m
pshichka [43]

Explanation:

Length of house, l = 54 ft = 16.45 m

Breadth of house, b = 48 ft = 14.63 m

Height of house, h = 8 ft = 2.43 m

We need to find the volume of the interior of the house. The house is in the form of cuboid. The volume of cuboid is given by :

V=l\times b\times h

V=16.45\ m\times 14.63\ m\times 2.43\ m

V=584.81\ m^3

Since, 1\ m^3=1000000\ cm^3

or the volume of the interior of the house, V=5.84\times 10^8\ cm^3

Hence, this is the required solution.

Given the mechanism of C5M action, what is the most likely reason that C5M concentrations greater than 2 µM were NOT used by the
Sunny_sXe [5.5K]

Answer:

It can cause a significant negative effects on certain tissues and target cells.

Explanation:

Generally, based on the mechanism of C5M, its presence in any experiment can harm certain tissues and target cells. Therefore, the use of a large amount (in terms of concentration above 2 µM) of C5M will enhance the negative effects of C5M on the surrounding/neighboring tissue as well as the normal division of target cells. That is the reason why a higher concentration was not used in the experimental runs.

If trees have leaves, then birds nests will increase. What the independent variable and the dependent variable?
Marianna [84]

The amount of birds nests depends on whether or not the trees have more or less leaves.

The independent should be the trees/leaves.

The dependent variable should be the birds nests.

Hope this helped ^-^

The position of a particle s given by x=3-2t+3t^2. What is its instantaneous velocity and instantaneous acceleration as t=3.
Leno4ka [110]

Explanation:

velocity = dx/dt

\frac{dx}{dt}  = 6t - 2 = 16

acceleration =

\frac{ {d}^{2}x }{d {t}^{2} }  = 6 \ \\
