answer
The beach ball will go the farthest because it's the lightest.
The tennis ball will go second farthest because it is the second lightest.
The baseball will go the third farthest because it is th third lightest'
The bowling ball will go the least far because it is the last farthest
From the given data chart, the way the mass of each ball affects its motion is that;
The highest mass will have the slowest motion while the least mass will have the fastest motion.
We are given;
Mass of baseball = 400 g
Mass of bowling ball = 900 g
Mass of beach ball = 10 g
Mass of tennis ball = 60 g
Now, according to Newton's first law of motion, the greater the mass of an object, the greater the inertia. This means that objects of higher mass would travel at slower motion than objects of lower mass because objects of higher mass would possess greater inertia.
Thus, looking at the masses of the objects given, the highest mass is 900g which is the mass of the bowling ball. Thus, it will be the slowest.
Next is baseball with 400g which is the third fastest motion.
Next is tennis ball with 60 g which is the second fastest motion
Next is beach ball with 10 g which is the fastest motion.

speed
acceleration
direction
magnitude
Answer:
Acceleration
Explanation:
Acceleration Is the rate change in velocity
Acceleration refers to the rate of change in velocity.
What is acceleration?
In mechanics, acceleration is the rate of change of the velocity of an object with respect to time. Accelerations are vector quantities (in that they have magnitude and direction). The orientation of an object's acceleration is given by the orientation of the net force acting on that object. The magnitude of an object's acceleration, as described by Newton's Second Law,is the combined effect of two causes:
1) the net balance of all external forces acting onto that object — magnitude is directly proportional to this net resulting force;
2)that object's mass, depending on the materials out of which it is made — magnitude is inversely proportional to the object's mass.

a) The volume of one mole of gaseous nitrogen at standard temperature and pressure is 22.4 L. The density of liquid nitrogen at -196°C is 0.808 g/mL. What is the volume of one mole of liquid nitrogen?
Answer:
34.653mL or 0.03465L
Explanation:
Density (g/mL) = mass (g) / volume (mL)
The mass of one mole of liquid nitrogen is 14g for one atom × 2 moles = 28mol.
Since density of the liquid nitrogen is 0.808 g/mL, the volume can be calculated thus:
Volume = mass/density
Volume = 28/0.808
Volume = 34.653mL
In litres, the volume will be 0.03465L

Moles of CH₄ react = 6 mole
Moles of water formed = ?
Solution:
CH₄ + 2O₂ → CO₂ + 2H₂O
Now we will compare the moles of CH₄ with water.
CH₄ : H₂O

Answer:
The correct answer is 1840.96 Joules
Explanation:
It should be noted that both calories and Joules are units of energy, thus this question is simply a conversion question. To convert 440 calories to joules, we say
1 calorie = 4.184 joules
440 calories = ?
cross multiply
? = 440 × 4.184/1
? = 1840.96 Joules
1840.96 Joules of energy is present in Mr. Beaulieu's breakfast

An irregular shaped piece of metal wha a mass of 0.251 lb was placed into a graduated cylinder containing 50.00 mL of water; this raised the water to 67.50 mL.
What is the density, in g/cm3, of the metal?
Answer:
[tex]\rho= 6.51g/cm^3[/tex]
Explanation:
Hello!
In this case, since the density is defined as the degree of compactness of a substance, and is defined as the mass over the volume:
[tex]\rho= \frac{m}{V}[/tex]
Given the displaced volume, we can compute the volume of the piece of metal via the following subtraction:
[tex]V=67.50mL-50.00mL=17.50mL=17.50cm^3[/tex]
Since the piece of metal displaces the water to the final volume. Moreover, given the mass in lb, we compute it grams as follows:
[tex]m=0.251lb*\frac{453.6g}{1lb} =113.85g[/tex]
Thus, the density turns out:
[tex]\rho= \frac{113.85g}{17.50cm3}\\\\\rho= 6.51g/cm^3[/tex]
Best regards.
