What will it’s change in temperature be?

_’c?

72.8°C

Explanation:

Step 1:

Data obtained from the question. This include the following:

Specific heat capacity (C) = 0.24J/g°C

Mass (M) = 15g

Heat (Q) = 262J

Change in temperature (ΔT) =..?

Step 2:

Determination of the change in temperature.

The change in temperature, ΔT can be obtained as follow:

Q = MCΔT

262 = 15 x 0.24 x ΔT

Divide both side by 15 x 0.24

ΔT = 262 / (15 x 0.24)

ΔT = 72.8°C

Therefore, the change in temperature, ΔT is 72.8°C

answer: a tank of height h is filled with water and sits on the ground. water squirts from a hole at a height y above the ground and has a range r. for two y values, 0 and h, r is zero. determine the value of y for which the range will be a maximum.

explanation:

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
