Based on what you've learned about heat energy, explain the factors that would determine how quickly a piece of meat cooked on a

barbecue grill. Why would the amount of water in the meat affect the speed of cooking?

Answer and Explanation:

Heat is a form of energy. It is the total energy of a system associated to the the movement of its molecules or molecular motion.

It depends on various factors like enthalpy of the system, its pressure, temperature, etc.

In the case mentioned, the pace at which meat is cooked on a barbecue grill depends on the water content of the meat and the barbecue grill temperature.

The reason for the cooking speed being affected by amount of water in the is that meat heat energy required to remove the excess water for the proper cooking depends on the water content which if removed completely will result in uncooked meat.

The more the water content the more is the energy requirement to remove it.

Answer:

Explanation:

Water has a very high specific heat capacity of about 4.186 J/C. This means that the more water that a piece of meat holds, the longer is takes to cook since the water requires more energy to remove from the meat.

The speed of cooking also depends on factors such as the thickness of the meat and the temperature of the grill. The thicker a piece of meat is, the longer it takes for the entire piece of meat to heat completely through. The higher the temperature of the grill, the quicker the heat energy spread throughout the meat.

A hockey stick strikes a hockey puck of mass 0.17 kg. If the force exterted on the hockey puck is 35.0 N and there is a force of
GREYUIT [131]

Answer:

a=190\ m/s^2

Explanation:

Mass of a hockey puck, m = 0.17 kg

Force exerted by the hockey puck, F' = 35 N

The force of friction, f = 2.7 N

We need to find the acceleration of the hockey puck.

Net force, F=F'-f

F=35-2.7

F=32.3 N

Now, using second law of motion,

F = ma

a is the acceleration of the hockey puck

a=\dfrac{F}{m}\\\\a=\dfrac{32.3}{0.17}\\\\a=190\ m/s^2

So, the acceleration of the hockey puck is 190\ m/s^2.

what is the acceleration of a bowling ball that starts at rest and moves 300m down the gutter in 22.4 sec
exis [7]
<span>Acceleration is the change in velocity divided by time taken. It has both magnitude and direction. In this problem, the change in velocity would first have to be calculated. Velocity is distance divided by time. Therefore, the velocity here would be 300 m divided by 22.4 seconds. This gives a velocity of 13.3928 m/s. Since acceleration is velocity divided by time, it would be 13.3928 divided by 22.4, giving a final solution of 0.598 m/s^2.</span>

By standard convention, both the electric potential and the the electric potential energy between two charges is taken to be zer
shusha [124]

Answer: at when distance r = infinity.

Explanation: The formulae for the electric potential of an electric charge to an arbitrary point is given by the formulae below

V = q/4πεr

V = electric potential (volts)

q = magnitude of electric charge

ε = permittivity of free space

r = distance between arbitrary point and charge.

In the equation above, it can be seen that only electric potential (v) and distance (r) is a variable, and there is an inverse relationship between them (an increase in one leads to a decrease in the other)

Thus to have zero value of electric potential (v= 0) we have to have the largest value of r ( r = infinity).

Same goes for electric potential energy between two charges, the formulae is given below as

W = q1 *q2/4πεr

W= electric potential energy

q1 = magnitude of first charge.

q2 = magnitude of second charge

ε = permittivity of free space

r = distance between arbitrary point and charge.

Also, all values are constant aside from electric potential energy (w) and distance (r) which have an inverse relationship.

Thus to have zero value of electric potential energy (w =0), we have to get an infinite value of distance ( r =infinity)

Which biome contains mostly coniferous trees and receives 35 to 100 cm of rain per year?
a_sh-v [17]

The question is incomplete as it does not have the options which are:

deciduous forest

taiga (boreal forest)

temperate rainforest

tropical rainforest

Answer:

Taiga (boreal forest)

Explanation:

A Biome refers to the habitat which is occupied by flora and fauna living in similar conditions.  These biomes are distinguished based on many features like precipitation, temperature and many other physical factors.

In the given question, the biome which receives an annual rainfall of 35 to 100 cm annually and is mostly covered by the coniferous trees is known as "Taiga biome" which is also known as Boreal forest.

The Taiga biome is one of the largest terrestrial biomes which is present in Eurasia and North America. The biome is characterised by the conifers trees and therefore is also known as the Coniferous trees.

Thus, Taiga (boreal forest) is the correct answer.
