Student one used bowling ball A in a bowling game against Student 2, who used bowling ball B. Use Newton’s Three Laws of Motion to explain the following:
Make a claim as to how Newton’s Three Laws of Motion can impact the bowling game for the 2 students. .
Use the image below and your background knowledge of how mass, acceleration, and force differ for the two bowling balls to support your claim, and provide reasoning as to how this evidence supports your claim.
Explain what variable the players could manipulate to maximize the force exerted on the pins.
Answer:
Newton’s Three Laws of Motion has a great impact.
Explanation:
Newton’s Three Laws of Motion has a great impact on the bowling game for the 2 students. When the student one throw ball to the student 2, the ball decrease its speed due to the gravity and opposing air. If these forces are removed from the system the ball will continue its motion till another force is applied on it. When the force applied to the ball it produces acceleration in the direction to the applied force. If the ball touches the ground it bounce back with equal force which is a reaction of the ground.

I mon runs a distance of 10km in 5 ms
he overage speed
Note: Your question inputs seem a little odd. But, I am assuming that you really mean '10km in 5 ms'.
Answer:
The Average speed = 15000 / 0.005 = 3000000 m/s
Explanation:
Average speed can be calculated by dividing the total distance covered by the total time.
Average speed = Total Distance / Total time
Given
Total distance = 15km = 15(1000) = 15000 m Total time = 5 ms = 0.005 seconds
Thus,
Average speed = Total Distance / Total time
Average speed = 15000 / 0.005 = 3000000 m/s

Which of the following electromagnet will have the strongest force?
1: A battery with no loops or wire around the nail
2: A battery with 10 loops of wire around the nail
3: A battery with 3 loops of wire around the nail
4:A battery with 15 loops or wire around the nail
Answer:
4:A battery with 15 loops or wire around the nail
Explanation:
More loops equals more force
A battery with [tex]15[/tex] loops or wire around the nail have the stronger force.
So, option 4 is correct.
Define electromagnet.An electromagnet is a system that contains of a magnetic encircled by a coil that conducts an electric current to ionize the core.
Wherever controllable magnetism are required, such as in devices where the magnetic flux must be adjusted, reversed, or turned on and off, an electromagnet is utilized.

is lighting firecrackers a form of conduction, convention, or radiation
Answer:
Convection
Explanation:
conduction is like, electricity. radiation is like using a microwave.
Answer:
conduction
Explanation:
recall that conduction is the transfer of heat between objects that come in direcr contact.
You are putting heat directly on the part of the firework that allows it to spark, therefore it is conduction.
Convection takes place within a fluid.
Radiation is indirect heat through waves. (think of the sun warming us indirectly)
why is thouching the live wire of an appliane when it is connecfed to the mains dangerous
Answer: The live wire is the most dangerous one, since it is at 230 V. it should never touch the earth wire (unless the insulation is between them, of course!), because this would make a complete circuit from your mains supply to the ground (earth). A shock or fire would be highly likely.

A football is kicked with a speed of 18 m/s at an angle of 65° to the horizontal. How far does the football travel horizontally before it hits the ground?
The horizontal distance traveled by the football is determined as 25.33 m.
Horizontal distance traveled by the football
The horizontal distance traveled by the football is calculated as follows;
X = u²sin(2θ)/g
where;
u is the initial speedg is acceleration due to gravityX = (18² x sin(2 x 65))/9.8
X = 25.33 m
Thus, the horizontal distance traveled by the football is determined as 25.33 m.

Displacement = Area under the velocity-time graph
So to find the displacement of a particle from 7 to 8 seconds we take the triangle and calculate its area.
[tex]Area\ of\ a\ right\ angled\ triangle = \frac{1}{2}*(base)*(height) \\\\Area\ of\ a\ right\ angled\ triangle = \frac{1}{2}*(1)*(3) \\\\Area\ of\ a\ right\ angled\ triangle = 1.5[/tex]

Los muelles de un remolque están calibrados para soportar su peso, cuando se carga el remolque con 2100 kg, la fuerza ejercida es de 20580 N comprime los muelles de un remolque 5,5 cm a)Longitud que desciende el remolque si se carga con 28000 N b)Si ha descendido 4,2 cm la carga
Answer:
a) El remolque desciende 7.4 cm
b) La carga debe ser de 15715.6 N ó 1603.6 kg
Explanation:
Para los cálculos que involucren muelles, se aplica la Ley de Hooke, la cual relaciona el efecto de una Fuerza y el cambio de longitud que esta ejerce, en un resorte de elasticidad dada.
Escrito en fórmula:
[tex]F=-k \cdot \Delta L[/tex]
Donde:
F es la fuerza ejercida
k es la constante elástica del muelle
ΔL es la variación de longitud del muelle
El problema indica que al cargar 2100 kg se ejerce una fuerza de 20580 N
Esto se corrobora con la 2da ley de Newton y asumiendo una aceleración de gravedad de 9.8 [tex]\frac{m}{s^{2} }[/tex]
[tex]F_{1} =m \cdot a\\F_{1}=2100kg \cdot 9.8\frac{m}{s^2}\\F_{1}=20580N[/tex]
Esta fuerza comprime o reduce la longitud del muelle en 5.5 cm. Usando estos datos en la Ley de Hooke, podemos obtener la constante elástica k:
[tex]F=-k \cdot \Delta L\\20580N=-k \cdot (-0.055m)\\\\k=\frac{20580N}{0.055m}\\k= 374181\frac{N}{m}[/tex]
Ahora ya tenemos los datos para resolver las preguntas:
a) Longitud que desciende el remolque si se carga con 28000 NAplicando directamente la formula de la Ley de Hooke:
[tex]F=-k \cdot \Delta L\\\Delta L=\frac{F}{-k} \\\Delta L= \frac{28000N}{-374181\frac{N}{m}} \\\Delta L=-0.074 m = -7.4cm[/tex]
b) Si ha descendido 4,2 cm la cargaEn este caso debemos calcular la fuerza necesaria que haga descender el remolque 4.2cm. Nuevamente utilizando la Ley de Hooke con estos nuevos datos:
[tex]F=-k \cdot \Delta L\\F=-374181\frac{N}{m} \cdot (-0.042m)\\F=15715.6N[/tex]
Si queremos saber la carga en kilogramos:
[tex]F = m \cdot a\\m = \frac{F}{a} \\m = \frac{15715.6N}{9.8\frac{m}{s^2} }\\m= 1603.6 kg[/tex]

In 1989 Carl Lewis established a world record when he ran the hundred meter dash in 9.92 seconds. What was his average speed (in M/S) for the race? Remember to include your data, equation, and work on solving the problem.
Answer:
10.08 m/s
Explanation:
The average speed of a body or an object can be calculated from the ratio of the total distance traveled by the body/object to that of the time taken to cover the distance.
Mathematically,
Average speed = total distance/total time
The total distance covered by Carl Lewis = 100 m
The total time taken = 9.92 s
Hence,
Average speed of Carl Lewis = 100/9.92
= 10.08 m/s
Which organisms release carbon dioxide as waste?
A rock has a mass of 3.1 kg. What is its weight on earth
Answer:
W = 30.38 N
Explanation:
Given that,
Mass of a rock, m = 3.1 kg
We need to find the weight of the rock on the surface of Earth. Weight of an object is given by :
W = mg
g is the acceleration due to gravity, g = 9.8 m/s²
W = 3.1 kg × 9.8 m/s²
= 30.38 N
So, the weight of the rock on the Earth is 30.38 N.

what about power: when shoveling versus using a snow blower, is power more, less, or the same? explain.
A snow blower is more powerful because it's easier, and it moves large amounts of snow easily. Shoveling uses all of your power. It can be difficult and it takes a long time to get the snow off of your lawn.
Therefore, using a snow blower is more powerful than using a shovel.
