Answer:
Explanation:
Think of it this way: An elephant has more inertia than a human. It is much harder to push an elephant across a floor than it is a human, and much harder to stop the elephant once it is moving. Therefore, by definition, an elephant has more mass than a human.

Use the principle of superposition (Equation 1.3) to predict the electric field at the point 0.5 meters to the right and 1.5 meters above the 5 nC charge. Express your result both in terms of x and y components, and then in terms of total magnitude and direction.
Answer:
Explanation:
The x component of electric field Ex = k Q / R²
= 9 x 10⁹ x 5 x 10⁻⁹ / .5²
= 180 N .
The y component of electric field Ey = k Q / R²
The y component of electric field Ey
= 9 x 10⁹ x 5 x 10⁻⁹ / 1.5²
= 20 N
Total field = [tex]\sqrt{180^2+20^2}[/tex]
= 181.1 N .
Angle with x axis = Tanθ = Ey / Ex = 20 / 180 = .111
= 6.33⁰

Two teams of girls are having a hug of war and neither side is winning. Each of the four girls on the west team is pulling with a force of 250. N. Three of the four girls on the east team are pulling with a force of 260 N each. With what force is the fourth girl on the east pulling.
Answer:
220N
Explanation:
Given that the first time has 4 girls
each girl pull at 250N, therefore the total force
250X4= 1000N
For the second team, the three girls out of the four pulls at 260N each,
let the fourth girl pulls at xN
the total force is 3X260+x
=780+x
we know that the total force on the west must equal the total force on the east
so
1000=780+x
solving for x we have
x=1000-780
x=220N
Therefore the fourth girl on the second team pulls at 220N

A sample of gold has a mass of 96.5g and a volume of 5.00cm^3. What is the density of gold?
Explanation:
sample of gold has a mass of 96.5 g and a volume of 5.00 cm3. The density of gold is a. 0518 g/cm3.
Taking into account the definition of density, the density of gold is 19.3 [tex]\frac{g}{cm^{3} }[/tex]
But first you must know the definition of density. Density is defined as the property that matter, whether solid, liquid or gas, has to compress into a given space.
In other words, density is the relationship between the weight (mass) of a substance and the volume that the same substance occupies.
The expression for the calculation of density is the quotient between the mass of a body and the volume it occupies:
[tex]density=\frac{mass}{volume}[/tex]
From this expression it can be deduced that density is inversely proportional to volume: the smaller the volume occupied by a given mass, the higher the density.
In this case, you know that:
mass= 96.5 gvolume= 5 cm³Replacing in the definition of density:
[tex]density=\frac{96.5 g}{5 cm^{3} }[/tex]
Solving:
density= 19.3 [tex]\frac{g}{cm^{3} }[/tex]
In summary, the density of gold is 19.3 [tex]\frac{g}{cm^{3} }[/tex]

A container of rocks is brought back from the Moon's surface where the acceleration due to gravity is 162 meters per second if the total mass of the container of rocks is 650 kilograms, what is its weight on
Earth's surface
Answer:
6318 N
Explanation:
From the question given above, the following data were obtained:
Acceleration due to gravity of the moon (gₘ) = 1.62 m/s²
Mass (m) of container = 650 kg
Weight (W) of container on the earth =.?
Next, we shall determine the acceleration due to gravity of the earth. This can be obtained as follow:
Acceleration due to gravity of the moon (gₘ) = 1.62 m/s²
Acceleration due to gravity of the earth (gₑ) =.?
gₘ = 1/6 × gₑ
1.62 = 1/6 × gₑ
1.62 = gₑ /6
Cross multiply
gₑ = 1.62 × 6
gₑ = 9.72 m/s²
Finally, we shall determine the weight of the container on the earth as follow:
Mass (m) of container = 650 kg
Acceleration due to gravity of the earth (gₑ) = 9.72 m/s²
Weight (W) of container on the earth =.?
W = m × gₑ
W = 650 × 9.72
W = 6318 N
Therefore, the weight of the container on earth is 6318 N
1. A car is traveling at 36 m/s hits a tree and comes to rest in 0.05 seconds.
a. What is the acceleration of the car?
b. Airbags deploy in a car if the acceleration of a car exceeds -600 m/s^2 Will the airbags deploy?
Answer: a. -720m/s^2
b. Yes, airbags will deploy
Explanation:
The formula for acceleration is:
= (Final velocity - Initial velocity)/Time
Final velocity = 0m/s
Initial velocity = 36m/s
Time taken = 0.05s
= (Final velocity - Initial velocity)/Time
= (0 - 36)/0.05
= -36/0.05
= -720m/s^2.
Since it's negative, it shows that there was a deceleration.
2. Yes the airbag will deploy since the acceleration gotten is more than -600 m/s^2.
Consider this situation: A force is applied to a box to move it
to the right across the kitchen floor. Of the forces listed,
identify which act upon the box.
Answer:
The static "frictional force" and the "kinetic friction" will act on the box.
When A force is applied to a box to move it to the right across the kitchen floor, static friction force comes into play before start moving. When the box starts moving, dynamic friction force comes into play.
What is friction?
The resistance provided by surfaces in touch as they move past one another is known as friction.
To walk without slipping, traction is provided by friction. In most situations, friction is advantageous. They do, however, give a strong amount of opposition to the move.
When A force is applied to a box to move it to the right across the kitchen floor, static friction force comes into play until it starts moving. When the box starts moving, dynamic friction force comes into play.

Goal: Use dimensional analysis to solve conversion problems. 1. Observe: In the question, you are asked to convert kilometers to centimeters. To do this, first you will convert kilometers to meters. Drag the 1000 meters/1 kilometer tile down. A. What do you notice? __________________________________________________ B. Because kilometers appear in the numerator of one term and in the denominator of another, they cancel, or disappear. The process of converting units by canceling is called dimensional analysis. How many meters are in 0.828 kilometers? ________________________________ C. A meter is a much shorter unit of measurement than a kilometer. Based on this fact, does your answer to B make sense? ______________________________________
Answer:
A. The kilometers unit is cancelled out and the result shown is 828 meters.
B. 828 meters are found in 0.828 Kilometers
C. Yes
Explanation:
A. When the 1000 meters/1 kilometer tile is dragged down, the kilometers unit is cancelled out and the value 828 meters appears.
This is because the kilometers appear in the numerator of one term and in the denominator of another, they cancel, or disappear. The process of converting units by canceling is called dimensional analysis.
B. 0.828 Kilometers * 1000 meters/1 kilometer = 828 meters
Therefore, there are 828 meters in 0.828 kilometers.
C. A meter is a much shorter unit of measurement than a kilometer. Based on this fact, it does make sense that 0.828 Kilometers which is less than 1 kilometer is equal to 828 meters.
(A) The process of converting units by canceling is called dimensional analysis.
(B) There are 828 meters in 0.828 kilometers.
(C) It does make sense that 0.828 Kilometers which is less than 1 kilometer is equal to 828 meters.
The given problem is based on some basic fundamentals and applications of dimensional analysis. So as per the given problem, each subpart says,
A.
When the 1000 meters/1 kilometer tile is dragged down, the kilometers unit is cancelled out and the value 828 meters appears.
This is because the kilometers appear in the numerator of one term and in the denominator of another, they cancel, or disappear. The process of converting units by canceling is called dimensional analysis.
Thus, we can conclude that the process of converting units by canceling is called dimensional analysis.
B.
Converting the given value of kilometers into the meters as,
0.828 Kilometers * 1000 meters/1 kilometer = 828 meters
Thus, we can conclude that there are 828 meters in 0.828 kilometers.
C.
A meter is a much shorter unit of measurement than a kilometer. Based on this fact, it does make sense that 0.828 Kilometers which is less than 1 kilometer is equal to 828 meters.
Thus, we can conclude that it does make sense that 0.828 Kilometers which is less than 1 kilometer is equal to 828 meters.
