Answer:

Net Force Formula: F1+F2+F3...+FN

*(MAKE SURE YOU MAKE NOTE OF THE NEGATIVE FORCES AND SUBTRACT THEM!)*

Explanation:

Top left: 17N+25N+25N-42N= 25N

Top right: 65N+200N-65N-150N-200N= 150N

Bottom left: 189N+123N+284N-96N-188N-312N= 0N

Bottom right: 34N+77N-12N-34N= 65N

I hope this helps! :))

list all the storage forms of energy that forms of energy that you are familiar with. for each storage form, give an example of

ella [17]

Storage form of energy:

Potential energy
Nuclear energy
electrical energy
thermal energy
magnetic energy

Potential energy:

All stationary objects are having potential energy stored in it. This energy can be transferred in form of kinetic energy when it comes in the motion from rest. Example, An object placed at height h having potential energy in it. When it comes in motion from the rest the potential energy is converted into kinetic energy.

Nuclear energy:

Nuclear energy is energy that is stored in nucleus of any element. Example, fusion reaction on sun gives earth solar energy.

Electric energy:

Electrical energy is due to movement of the electrical charges. Example, In elctrical batteries electrical energy is stored.

Thermal energy:

Thermal energy is the internal energy of a substance that is transferred to other substance in the form of heat. Example, on heating water is a beaker stem energy is developed.

Magnetic energy:

Magnetic energy is the potential energy stored in the magnetic field. Example, using magnetic energy electric field is produced according to Faraday's law.

A gas sample is heated from -20.0°C to 57.0°C and the volume is increased from 2.00 L to 4.50 L. If the initial pressure is 0.14

Svetach [21]

Answer:

The answer is e.

Explanation:

We take:

$T_{1}=253K$

$V_{1}=2.00 l$

$P_{1}=0.14atm$

$V_{2}=4.50 l$

$T_{2}=330K$

Taking the gas as an ideal gas, we can use the ideal gas law:

$\frac{PV}{nRT}$

⇒ $n=\frac{P_{1}V_{1}}{RT_{1}}$ ⇒ $n=0.013mol$

Then:

$P_{2}=\frac{nRT_{2}}{V_{2}}$ ⇒ $P_{2}=0.0811 atm$

Taking R=0.08205atmL/molK.

Elenna [48]

Physical anthropology studies the human body. This discipline is aimed at analyzing the evolution and diversity of human beings.

<h3>What is physical anthropology?</h3>

Physical anthropology is a branch of anthropology that studies the evolution and diversity of human beings.

Physical anthropology is also called biological anthropology due to its close relation with biological sciences.

This branch of anthropology (physical anthropology) is aimed at assessing the evolution and physical variation and/or behaviors of human beings.

PLEASE HELP I HAVE FINALSSS

vitfil [10]

Answer: 26.67 m/s

Explanation:

Given

Length traveled by the ball $s=40\ m$

Time taken to reach the goal post is $t=3\ s$

Initial velocity $u=0\ m/s$

Using the second equation of motion

$\Rightarrow s=ut+\frac{1}{2}at^2\\\Rightarrow 40=0+\frac{1}{2}a(3)^2\\\Rightarrow a=\frac{80}{9}\ m/s^2\\$

Now using

$\Rightarrow v^2-u^2=2as\\\\\Rightarrow v^2-0=2\times \frac{80}{9}\times 40\\\\\Rightarrow v=\sqrt{\dfrac{80\times 80}{9}}=\dfrac{80}{3}\\\Rightarrow v=26.67\ m/s$

The velocity of ball will be 26.67 m/s
