A chunk of beef has a mass of 11.6 grams and a volume of 58 cm3. What is the density of the chucky beef?
Group of answer choices
46.4
0
672.8
0.2
5
Answer:
0.2g/cm³
Explanation:
Given parameters:
Mass of the beef = 11.6g
Volume = 58cm³
Unknown:
Density = ?
Solution:
Density is the mass per unit volume of a substance.
Density = [tex]\frac{mass}{volume}[/tex]
So;
Density = [tex]\frac{11.6}{58}[/tex] = 0.2g/cm³
Are there any steps of the rock cycle that do not connect directly to one another
Answer:
The three main rock types are igneous, metamorphic and sedimentary.
The three processes that change one rock to another are crystallization, metamorphism, and erosion and sedimentation.
Any rock can transform into any other rock by passing through one or more of these processes. This creates the rock cycle.
No
ALL rocks are connected in a cycle of creation, change, and destruction which is known as what is referred to as the rock cycle.
The rock cycle begins with molten rock, i.e, the magma below ground and the lava above ground, which cools and hardens to form igneous rock. These sediments can then be buried and hardened forming sedimentary rock.
RockA rock is a solid mass of geological materials. They are naturally formed, non-living earth material. Rocks are made of collections of mineral grains that are held together in a firm solid mass

A train travels a distance of 300 miles in 6 hours. What is the train's average speed?
A) 50 miles per hour
B) 50 hours per minute
C) 1800 miles per hour
D) .5 miles per hour
Answer:
A
Explanation:
Distance (d)=300 miles
Time Taken (t)=6 hours
Here, In 6 hours a train travel distance= 300m
In 1 hours a train travel distance= 300m/6
= 50
Hence, Average Speed is 50 miles per hour.
The right option is A) 50 miles per hour.
To calculate the average speed of the train in miles per hour, we use the formula below.
Formula:
S = d/t............... Equation 1Where:
S = average speed of the train.d = Total distance covered by the traint = total time.From the question,
Given:
d = 300 milest = 6 hours.Substitute these values into equation 1
S = 300/6S = 50 miles per hour.Hence, The right option is A) 50 miles per hour.

A common black ant discovers a piece of bread 85 cm east of the entrance of her nest. If the ant carries 10 bits of bread back to her nest on separate trips before moving on to other chores, what distance did she travel after discovering the bread? What was her displacement from the nest after dropping up the last bit of bread?
Answer:
19 x 85 = 1,615 for distance. Displacement is 0
Explanation:
The total distance traveled by the ant in 9 round trips and one 1/2 trip, or 19 one bash way trips: 19 x 85cm = 1615cm. The displacement of the ant after the tenth trip is 0 cm ( the displacement origin is the nest.)

What does the speed of air have to do with air pressure?
Detailed answer pls!!! i will give brainliest!!!!
Answer:
The air speeds up, and as it speeds up, its pressure—the force of the air pressing against the side of the object—goes down. ... This means that if the area in which the air is moving narrows or widens, then the air has to speed up or slow down to maintain a constant amount of air moving through the area.

A 2.00 kg ball is thrown upward at some unknown angle from the top of a 20.0 m high building. If the initial magnitude of the velocity of the ball is 20.0 m/s. What is the magnitude of the
FINAL VELOCITY when it strikes the ground? (Note: Ignore air resistance.)
Answer: 28.1
Explanation:
The total energy of the ball is the sum of its kinetic and potential energy. It is equal to 792 J. Then, the final velocity of ball when its strikes the ground is 28.1 m/s.
What is kinetic energy?Kinetic energy of an object is the energy gained by its motion whereas, potential energy is stored on the object when the object is at rest.
The total mechanical energy of the ball = Ke + Pe
given, mass of the ball = 2 Kg
height h= 20 m
initial velocity = 20 m/s
Then total energy = 1/2 mv² + mgh = 2 kg [(1/2(20 m/s)² + 9.8 m/s² ×20 m ] = 792 J.
The final velocity Vf = √(2E/m) =√(2×792 J/m)/2 Kg = 28.1 m/s
Therefore, the final velocity of the ball will be 28.1 m/s.

A particle with charge q on the negative x axis and a second particle with charge 2q on the positive x axis are each a distance d from the origin. Where should a third particle with charge 3q be placed so that the magnitude of the electric field at the origin is zero? (Use any variable or symbol stated above as necessary.)
Answer:
The charge 3q must be placed at a distance of 1.73d away from the origin.
Explanation:
The electric field at the origin due to q at distance, d from the origin is E = q/4πε₀d².
The electric field at the origin due to 2q at distance, d from the origin is E' = -2q/4πε₀d². (It is negative since it its directed towards the negative x-axis)
Now, the net electric field at the origin due to both charges is thus E" = E + E' = q/4πε₀d² + (-2q/4πε₀d²) = q/4πε₀d² - 2q/4πε₀d² = -q/4πε₀d².
The electric field due to 3q at a distance x from the origin is E₁ = 3q/4πε₀x².
Now, the net electric field E' must cancel out E₁ so that the electric field at the origin is zero.
So, E' + E₁ = 0
E' = -E₁
-q/4πε₀d² = -3q/4πε₀x²
1/d² = 3/x²
taking inverse of both sides, we have
x²/3 = d²
multiplying both sides by 3, we have
x² = 3d²
taking square root of both sides, we have
x = (√3)d
x = ±1.73d
So, the charge 3q must be placed at a distance of 1.73d away from the origin.
