The depth of the deepest footprint is 3 centimeters C. The footprints were made by a dog D. The footprints are oriented in an east-west direction
Answer:
C
C. The footprints were made by a dog.
The student may have noticed specific characteristics or features in the footprints that lead them to believe that they were made by a dog.
Hence, the correct option is C.
An inference is a conclusion or deduction based on evidence or observations. It involves making an educated guess or interpretation about something that may not be explicitly stated.
Out of the provided options, the most likely inference is The footprints were made by a dog.
This statement is an inference because it involves making a conclusion based on the observed footprints in the mud. The student may have noticed specific characteristics or features in the footprints that lead them to believe that they were made by a dog.
However, this inference might not be a definite conclusion, as there could be other animals or factors that create similar-looking footprints in the mud.
Therefore, The student may have noticed specific characteristics or features in the footprints that lead them to believe that they were made by a dog.
Hence, the correct option is C.

A shopping cart given an initial velocity of 2.0 m/s undergoes a constant acceleration to a velocity of 13 m/s. What is the magnitude of the carts acceleration if the time is 4.0?
Also if your really smart and have instagram please dm imaswagmeal and help me pls
Answer:
The acceleration is a = 2.75 [m/s^2]
Explanation:
In order to solve this problem we must use kinematics equations.
[tex]v_{f} = v_{i} + a*t\\[/tex]
where:
Vf = final velocity = 13 [m/s]
Vi = initial velocity = 2 [m/s]
a = acceleration [m/s^2]
t = time = 4 [s]
Now replacing:
13 = 2 + (4*a)
(13 - 2) = 4*a
a = 2.75 [m/s^2]
Think about what you already know. Why might two objects be affected differently if the same strength force is exerted on them?
Answer:Explanation:
If the same strength force is exerted on two objects, but the objects have the different masses, the object with less mass will have a greater change in velocity. ... Forces affect motion because they can change an objects motion.
The reason for two objects being impacted differently even a similar strength of the force is applied/exerted to them:
- Two objects might be affected differently on the application of a force of the same strength owing to the difference in their masses.
The second law of motion by Newton states that the rate of change of momentum of an object is directly proportional to the applied unbalanced force in the direction of the force.However, We know, Momentum = Mass × velocity.Hence, if the masses are different and the force applied is the same, the two objects will move with different velocities.

An athlete starts running from rest such that he covers a distance of 5mm in 0.50s with a constant change in velocity per unit time . when will he reach the finish line, if he is running a race of 50m?
Answer:
50 s
Explanation:
Given:
Δx = 0.005 m
v₀ = 0 m/s
t = 0.50 s
Find: a
Δx = v₀ t + ½ at²
0.005 m = (0 m/s) (0.50 s) + ½ a (0.50 s)²
a = 0.04 m/s²
Given:
Δx = 50 m
v₀ = 0 m/s
a = 0.04 m/s²
Find: t
Δx = v₀ t + ½ at²
50 m = (0 m/s) t + ½ (0.04 m/s²) t²
t = 50 s

1 a rectangular block of steel measures 4cm * 2cm* 1.5cm. its mass is 93 .6g
a) calculate the density of steel
b)steel is made up of almost entirely of atoms butt is denser than iron
suggest a reason for this
a) density = 93.6g/12cm³
= 7.8g/cm³
b) The reason is alloying
Explanation:
volume of the rectangular block = l× b × h
= (4 × 2 × 1.5)cm
= 12 cm³
density = mass/ volume
mass = 93.6g
volume = 12cm³
therefore,
density = 93.6g/12cm³
= 7.8g/cm³
b) °Steel is formed when alloying Iron with carbon.
°Alloying improves the physical properties of the metals and non-metals
A cell phone weighing 80 grams is flying through the air at 15 m/s. what is the kinetic energy?
Answer:
The answer is 9 JExplanation:
The kinetic energy of an object can be found by using the formula

A photo frame with a mass of 2.8 kg is hung from a nail according to the opposite figure. If we know that the nail is located exactly in the middle of the string and the frame does not touch the wall, how many newton is the tensile strength of the string?
Answer:
One string (side of) must support 1.4 kg.
T cos 15 = vertical force required by each side of the string
T cos15 = 1.4 * 9.8 N
T = 1.4 * 9.8 / cos 15 = 14.2 N

How do you find displacement with velocity and acceleration?
Displacement (s) of an object equals, velocity (u) times time (t), plus ½ times acceleration (a) times time squared (t2). Use standard gravity, a = 9.80665 m/s2, for equations involving the Earth's gravitational force as the acceleration rate of an object.
How do you find velocity from acceleration?
Multiply the acceleration by time to obtain the velocity change: velocity change = 6.95 * 4 = 27.8 m/s . Since the initial velocity was zero, the final velocity is equal to the change in speed. You can convert units to km/h by multiplying the result by 3.6: 27.8 * 3.6 ≈ 100 km/h.

what do waves create
Answer:
Waves transmit energy, not water, and are commonly caused by the wind as it blows across the ocean, lakes, and rivers. Waves caused by the gravitational pull of the moon and the sun are called tides.
Explanation:
Answer:
Waves are created by energy passing through water, causing it to move in a circular motion. However, water does not actually travel in waves. Waves transmit energy, not water, across the ocean and if not obstructed by anything, they have the potential to travel across an entire ocean basin. Waves are most commonly caused by wind.

Answer:
Explanation:
the cells need oxygen for metabolism, which also creates carbon dioxide as a waste product. The red blood cells then pick up the carbon dioxide and transport it back to the lung. There we exhale it when we breathe out. Red blood cells can also pick up or release hydrogen and nitrogen.
