Answer:

c=326.5177 J/kg.K

Specific heat is c=326.5177 J/kg.K

Explanation:

In order ti find the specific heat, we will proceed as follow:

Formula we are going to use is:

Q=m*c*\Delta T

Where:

Q is the heat energy added

m is the mass of sample

c is the specific heat

\Delta T is the temperature Rise.

First we will find the mass:

Weight=m*g  (g is gravitational acceleration=9.8 m/s^2)

m=\frac{weight}{g} \\m=\frac{27.2}{9.8} \\m=2.7755 \ kg

Rearranging above formula:

c=\frac{Q}{m* \Delta T}

c=\frac{1.45*10^4}{2.7755*16}

c=326.5177 J/kg.K

Specific heat is c=326.5177 J/kg.K

Answer:

a) increases

Explanation:

The increase in temperature causes the particles to move much faster. This in turn effects the collision rate of the particle which causes the chemical reaction. Thus the rate of chemical reaction increases.

So, we conclude that the rate of a chemical reaction is directly related to temperature. With increase in temperature there is an increase in the reaction rate and vice versa.

What does the octect rule state that explains why atoms bond ?
Simora [160]

Answer:

Explanation:

Atoms naturally bond with each other in an attempt to have 8 or zero valence electrons. This occurs in salts, covalent bonds, and mettalic bonds. This is how the octet rule demonstrates why atoms bond.

Hope this helps!

Alenkinab [10]

The mechanical advantage of the forklift is calculated to be 4.

<h3>MECHANICAL ADVANTAGE:</h3>
  • The mechanical advantage of a machine can be calculated by dividing the load (F) by effort (F). That is;

M.A = Load/Effort

  • According to this question, a crate required 900 newtons (N) of force to lift. The crate was lifted by a forklift with an engine that provided 225 N of force. The mechanical advantage is calculated as follows:

M.A = 900N ÷ 225N

M.A = 4.

Therefore, the mechanical advantage of the forklift is calculated to be 4.

Why does the gravitational field strength increase with latitude
otez555 [7]
The second major reason for the difference in gravity at differentlatitudes is that the Earth's equatorial bulge (itself also caused by centrifugalforce from rotation) causes objects at the Equator to be farther from the planet's centre than objects at the poles.
