This waterbottle has a mass of .5 kg. If the net force acting on the bottle is five and to the right what is the bottles acceleration (hint: use formula a=f/m
Answer:
a = 10/s^2
Explanation:
Answer:
a=10 m/s *2 right
Explanation:
The net force (0.5 kg) divided by the mass (5 N) = 10
The force moved the object to the right.
So you Would put this in the equation a=___ m/s *2 _____
And you would get a=10m/s*2 right

What is the magnitude of force required to accelerate a car of mass
1.7 × 103 kilograms by 4.75 meters/second2?
Answer:
The answer is 8075 NExplanation:
The force acting on an object given it's mass and acceleration can be found by using the formula
force = mass × accelerationFrom the question
mass = 1.7 × 10³ kg = 1700 kg
acceleration = 4.75 m/s²
We have
force = 1700 × 4.75

Igneous rock can be changed into which type of rock through the application of heat and pressure?
metamorphic rock
clastic sedimentary rock
non-foliated igneous rock
foliated igneous rock
Answer:
metamorphic rock
Explanation:
Igneous rocks can be changed into metamorphic rocks when heat and pressure are applied to the rock.
Pressure and heat in the presence of a fluid phase cause metamorphic transformation of a prolith.
At the right temperature and pressure, an igneous rock will not form magma but will undergo mineralogical changes to form metamorphic rocks. These changed rocks have different mineral facies that are different from those of the prolith.Through heat and pressure, igneous rocks can be transformed into metamorphic rocks.
Answer:
classic sedimentary rock

1) Calculate the speed of a runner who runs 100 m in 20s
This is how you calculate his speed, for the 100metres. That is, the average speed for the entire distance, including the start from intertia until the race end where the athlete is decelerating. Multiply the time by 10, and divide 3600 by that figure. i.e. 10 by10 equals 100. Divide 3600 by 100 and you get 36 which is the speed figure you requested.
A female athlete ran 200 metres a few years ago and in the middle section of the race covered 100 metres in that race in a time under 10 seconds. That is, she ran a sub 10second 100metres from a flying start. This great athlete from Slovenia, also ran a 100 metre race (from a stationary start) in a time under 11 seconds, when she was 48 years of age. Her name is Merlene Ottey.
While Juliet was watching Romeo ran at a speed of 3.3 m/s straight off the end of a diving board
that is 3 m above the water. How long was he airborne before he hit the water?

Which statement describes an endothermic reaction? A. Energy is released by the reaction. B. Energy is absorbed by the reaction. C. No energy is transfered by the reaction. D. Energy is created in the reaction.
Answer:It's B energy is absorbed by the reaction,hope this helps
Explanation:
Any reaction in which energy is absorbed is said to be endothermic. Hence, option B is correct, but the rest are not correct.
What is an Endothermic Reaction?In every chemical process, energy is involved. When new bonds form in products, energy is produced. Reactant bonds are broken using energy. Exothermic reactions are those that produce more energy when new bonds form in the products than is needed to break existing bonds in the reactants.
In contrast, endothermic reactions are the opposite. Endothermic reactions release more energy when new bonds form in the products than is required to break bonds in the reactants.
During the reaction, a large amount of energy is absorbed.

Consider a spring that does not obey Hooke's law very faithfully. One end of the spring is fixed. To keep the spring stretched or compressed an amount x, a force along the x-axis with x-component Fx=kx−bx2+cx3 must be applied to the free end. Here k=100N/m, b=700N/m2, and c=12000N/m3. Note that x>0 when the spring is stretched and x<0 when it is compressed.
Answer:
The work done will be 0.115 J.
Explanation:
Given that,
[tex]k=100\ N/m[/tex]
[tex]b=700\ N/m^2[/tex]
[tex]c=12000\ N/m^3[/tex]
A force along the x-axis with x-component,
[tex]F(x)=kx-bx^2+cx^3[/tex]
Suppose, How much work must be done to stretch this spring by 0.050 m from its unstretched length?
We need to calculate the work done
Using formula of work done
[tex]W(x)=\int{F(x)dx}[/tex]
Put the value into the formula
[tex]W(x)=\int{(kx-bx^2+cx^3)dx}[/tex]
[tex]W(x)=\dfrac{kx^2}{2}-\dfrac{bx^3}{3}+\dfrac{cx^4}{4}[/tex]
Put the value of k,b,c and x
[tex]W(0.050)=\dfrac{100\times(0.050)^2}{2}-\dfrac{700\times(0.050)^3}{3}+\dfrac{12000\times(0.050)^4}{4}[/tex]
[tex]W(0.050)=0.115\ J[/tex]
Hence, The work done will be 0.115 J.
The value of spring displacement is greater than zero. Therefore, spring is stretched.
Force in spring :
It is given as, [tex]F=kx[/tex]
Where k is constant and x is amount of displacement.
The force function is given that,
[tex]F(x)=kx-bx^{2}+cx^{3}[/tex]
Here given that, [tex]k=100N/m, b=700N/m^{2} , c=12000N/m^{3} .[/tex]
Substitute all values in above equation,
[tex]F(x)=100x-700x^{2} +12000x^{3}[/tex]
To check, the spring is stretched or it is compressed.
Substitute f(x) = 0
We get x is greater than zero.
Thus, The value of spring displacement is greater than zero. Therefore, spring is stretched.

At highway speeds, a particular car is capable of an acceleration of about 1.6 m/s?. At this rate,
does it take the car to speed up from 80 km/hr to 110 km/hr? Round your answer to
Two significant figures
Given parameters:
Acceleration of the car = 1.6m/s
Initial speed = 80km/hr
Final speed = 110km/hr
Solution:
Time taken to achieve this speed = ?
Solution:
Acceleration is the rate of change of velocity with the time taken.
Mathematically;
a = [tex]\frac{V - U}{T}[/tex]
where a is the acceleration
V is the final velocity
U is the initial velocity
T is the time taken
Now make the unknown time the subject of the expression;
aT = V - U
T = [tex]\frac{V - U}{a}[/tex]
Convert the given acceleration to km/hr;
1.6m/s = 1.6 x [tex]\frac{m}{s}[/tex] x [tex]\frac{1km}{1000m}[/tex] x [tex]\frac{3600s}{1hr}[/tex] = 5.76km/hr
Input the parameters and solve;
T = [tex]\frac{110 - 80}{5.76}[/tex] = 5.2hrs
The time taken is 5.2hrs

Explanation:
1.wrap bar magnet in a plastic baggie and remove the iron filings from the mixture by using a bar magnet. Place a small piece of scrap paper on the scale and “tare” the scale. Then place filings on the scrap paper and record (e) the mass of the iron filings. Don't throw out the iron–save it to be recollected.
2.When sand is added to water it either hangs in the water or forms a layer at the bottom of the container. Sand therefore does not dissolve in water and is insoluble. It is easy to separate sand and water by filtering the mixture. Salt can be separated from a solution through evaporation.
3.Sand (mostly silicon dioxide) is not.
Pour the salt and sand mixture into a pan.
Add water. ...
Heat the water until the salt dissolves. ...
Remove the pan from heat and allow it to cool until it's safe to handle.
Pour the salt water into a separate container.
Now collect the sand.
Pour the salt water back into the empty pan.
Heat the salt water until the water boils. Continue boiling it until the water is gone and you're left with the salt.
Another way you can separate the salt water and sand is to stir up the sand/salt water and pour it through a coffee filter to capture the sand.

Answer:
Li⁻
Explanation:
# of protons = # element on the Periodic Table.
# of protons (+) + # of electrons (-) = overall charge
3 protons is the 3rd element on the Periodic Table: Lithium
All elements on the Periodic Table have a neutral charge. Lithium neutral has 3 protons and 3 electrons.
We are given 4 electrons; 3 + -4 = -1 charge overall.
Therefore, our ion is Li⁻
