In addition to the resultant force acting on an object, the mass of the object should be known to find the acceleration. So, the mass is the answer.
Newton's second law of motion states that
a = F / m
Where:
a is the acceleration of the object,
The net force acting on the object is F
m is the mass of the object.
By dividing the net force (F) by the mass (m), you can determine the acceleration (a) of the object.
So, both the net force and the mass are necessary to calculate the acceleration. So, the mass is the answer.

Resistor 1 has a resistance of 10 N and
carries a current of 3 A. Resistor 2 has a resistance of
5 and carries a current of 10 A. Which resistor has
the greater potential difference?
Answer:
Resistance 2.
Explanation:
Ohm's law states that at constant temperature, the current flowing in an electrical circuit is directly proportional to the voltage applied across the two points and inversely proportional to the resistance in the electrical circuit.
Mathematically, Ohm's law is given by the formula;
[tex] V = IR[/tex]
Where;
V represents voltage measured in voltage. I represents current measured in amperes. R represents resistance measured in ohms.Note: Voltage is the same as potential difference.
Given the following data;
Resistance 1 = 10 Ohms
Current 1 = 3 Amperes
Potential difference 1 = current * resistance
Potential difference 1 = 3 * 10
Potential difference 1 = 30 V
To find the potential difference in 2;
Resistance 2 = 5 Ohms
Current 2 = 10 Amperes
Potential difference 2 = 10 * 5
Potential difference 2 = 50 V
Therefore, Resistance 2 has greater potential difference.
Is potential energy higher at the equilibrium position?
A 1800 kg car moving south at 17.5 m/s collide with a 2800 kg car moving north. The cars stick together and move as a unit after the collision at a velocity of 5.22 m/s to the north. Find the velocity of the 2800 kg car before the collision
Answer:
v₀₂ = -2.67 m / s
Explanation:
Let's use the conservation of the moment, for this we define a system formed by the two cars.
Consider the north direction as positive and the subscript 1 will be used for car 1 and the subscript 2 for the second car
Initial instant. Before the crash
p₀ = -m₁ v₀₁ + m₂ v₀₂
Final moment. Right after the crash
p_f = (m₁ + m₂) v
p₀ = p_f
-m₁ [tex]v_{o1}[/tex] + m₂ v_{o2} = (m₁ + m2) v_{f}
v₀₂ = [tex]\frac{(m_1 +m_2) v }{m_2}[/tex]+ [tex]\frac{m_1 v_{o1} }{m_{1} }[/tex]
let's calculate
v₀₂ = [tex]\frac{(1800 +2800) 5.22 + 1800 (-17.5)}{2800}[/tex]
v₀₂ = -2.67 m / s
the negative sign indicates that the carriage moves in the opposite direction of the temperies
5. What do you think? At a baseball game, when you are far from the batter, you might see the batter hit the ball before you hear the sound of the hit. Why do you think this
happens?
Answer:
The speed of sound in air is lower compared to in solids and liquids.
Explanation:
Sound is a wave that can be generated by a vibrating body. Its speed through different media differs due to the nature of the media.
Since the molecules of solids are closely packed, sound can be easily transferred from one molecule to another at a faster rate. Thus, the high speed of sound in solids.
In liquids, the molecules are not as closely packed as solids. So that the speed of sound though liquids is lower compared to that of solids. Gases has its molecules farther apart, thus making the speed of sound through it the lowest compared to solids and liquids.
Therefore the sound of the batter hitting the ball is heard latter, due to its lower speed through the air.

A sample of hydrogen at 1.5 atm had its pressure decreased to 0.50 atm producing a new volume of 750 mL. What was its original volume?
245 ml
345 ml
123 ml
250.mL
Answer:
245 ml
Explanation:
rfdhccchhhgugvhh
The original volume of the sample of hydrogen is 250 mL. The correct option is the fourth option 250mL
From the question,
We are to determine the original volume of the hydrogen.
To do this,
We will use the Boyle's law formula
Boyle's law states that "the volume of a fixed mass of gas is inversely proportional to its pressure, provided that the temperature remains constant."
From Boyle's law we have that
P₁V₁ = P₂V₂
Where P₁ is the initial pressure
V₁ in the initial volume
P₂ is the final pressure
and V₂ is the final volume
From the question,
P₁ = 1.5 atm
P₂ = 0.50 atm
V₂ = 750 mL
Put the above parameters into the Boyle's law equation
P₁V₁ = P₂V₂
Then, we get
1.5 × V₁ = 0.50 × 750
1.5 × V₁ = 375
∴ V₁ = 375 ÷ 1.5
V₁ = 250 mL
Hence, the original volume of the sample of hydrogen is 250 mL. The correct option is the fourth option 250mL

What is experiment ?An experiment is a technique used to confirm or deny a hypothesis, as well as assess the possibility or effectiveness of something that has never been done before. Experiments show what happens when a certain component is modified, which sheds light on cause-and-effect relationships. The purpose and scope of experiments vary widely, but they always rely on a repeatable process and a rational examination of the outcomes. Natural experimental experiments are also a thing.
While a child may conduct simple experiments to better understand how objects fall to the ground, scientific teams may spend years conducting thorough research to increase their understanding of a phenomenon.
This experiment shows enthalpy is positive, heat is absorbed in this experiment. this breaks the atoms and it needed the energy.

The outside diameter of your teacher's rear bicycle tire is 16 inches. How far will he travel if the rear wheel makes 1200 revolutions on the road?
Answer:
241,274.32 inches
Explanation:
How far will he travel if the rear wheel makes 1200 revolutions on the road?
Since the rear wheel makes one revolution in the distance of a circumference of a circle, C with diameter, d = 16 inches
C = πd²/4
So, the distance, travelled in 1200 revolutions is D = 1200 × C = 1200πd²/4
Substituting d = 16 into D, we have
D = 1200πd²/4
D = 1200π(16)²/4
D = 76800π
D = 241,274.32 inches
