Two identical cows fell into a muddy hole. One fell on its side and the other on its feet.
Which one sunk furthest into the mud and explain your answer
Answer: The one that fell on its feet.
Explanation: The sinking of the two cows will depend on the pressure exert on the mud.
Pressure is the ratio of force to area.
The one which fell on its side would exert lower pressure because of its larger side of area. While the one that fell on its feet will exert greater pressure because of small area of its feet.
Therefore, the one that fell on its feet will sink furthest into the mud because of the ratio of the force to area of its feet ( pressure) is higher.

what is the mass of mr. thomson’s prius if his kinetic energy is 641300 J when he is driving at a velocity of 22 meters per second on the highway? please show work
Answer:
The mass of Mr. Thomson’s prius is 2650 kg.
Explanation:
We are given with, the kinetic energy of Mr. Thomson’s prius is 641300 J
He is moving with a velocity of 22 m/s
It is required to find the mass of Mr. Thomson’s prius.
Due to his motion, a kinetic energy will possess by him. The mathematical form of kinetic energy is given by :
[tex]K=\dfrac{1}{2}mv^2[/tex]
Solving for m
[tex]m=\dfrac{2K}{v^2}[/tex]
Plugging all the values, we get :
[tex]m=\dfrac{2K}{v^2}\\\\m=\dfrac{2\times 641300}{(22)^2}\\\\m=2650\ kg[/tex]
So, the mass of Mr. Thomson’s prius is 2650 kg.

A dog walks along The ground. If the dog applies an action force on the ground, what is the reaction force?
Please HELP
Explanation:
Action and reaction are two forces that are equal in magnitude but the direction is opposite.
When a dog walks along the ground, the action force is the force that dog applies on the ground. On the other hand, the reaction force is the force that the ground applies on the dog. It is based on Newton's third law of motion.
Four identical 2.5 mF capacitors are connected together electrically. What is the greatest possible capacitance of the combination? 0.50 mF, 0.42 mF, 0.63 mF, 10 mF, or 0.40 mF?
When capacitors are in PARALLEL, they add up. (like resistors in series)
If you connect these four capacitors in parallel, the combination behaves like a single capacitor of (4 x 2.5) = 10 mF.
That's the greatest capacitance you can make with these four pieces.

The reflection of a 10.0 cm object appears to be 18 cm tall and 9 cm behind the mirror.
What distance is the object from the mirror?
cm
Answer: 5cm
Explanation:
Given the following :
Image height = 18cm
Object height = 10cm
u = object distance
v = image distance = 9 cm
Using the relation:
image height/object height= v/u
18/10 = 9/u
Cross multiply
18 × u = 10 × 9
18u = 90
u = 90/18
u = 5cm
Therefore,
Object distance from mirror = 5cm
Answer:
5 cm

Define loudness and intensity of sound. How are the two concepts related?
Answer:
Hey mate, here's ur answer
-------------------------------------------------------------
Loudness refers to how a sound seems to a listener, whether it's loud or soft.
___________________________
Intensity is the sound power per unit area. It is independent of the sensitivity of the human ears.
___________________________
The loudness of a sound relates the intensity of any given sound to the intensity at the threshold of hearing. It is measured in decibels (dB).

Was the object accelerating during the time interval labeled “B”?
A) Yes
B) No
There's not enough information in the graph to determine whether it was or it wasn't. It could have been, but we can't tell.
Before I explain this answer, it's VERY important to know exactly what "accelerating" means:
-- "Accelerating" does NOT always mean "speeding up".
-- "Accelerating" means ANY change in velocity.
-- That can be ==> speeding up, or ==> slowing down, or ==> turning.
This graph is labeled "Velocity vs Time", but it isn't really. "Velocity" means speed AND direction. The graph only shows us the object's speed, but nothing about its direction.
During time-interval-B, the speed isn't changing, but the object could still be changing direction, like turning a corner, or on a curved path. We don't know. The graph doesn't show us that information.
The object could be accelerating during time-interval-B. It's true that the speed wasn't changing. But maybe the direction was. If the direction was changing, then we have to say the object was 'accelerating' during the interval labeled B .

An airplane flies 40km directly south in 10 minutes and 20 km directly east in five minutes, its average speed is:
a)2.98km/min
b)2km/min
c)8km/min
d)4km/min
Answer:
D. 4km/min
Explanation:
Since the question deals with "speed" and not "velocity", the direction does not matter.
the plane covers 40 + 20 km=60km in 10mins +5 mins=15mins
60 km - 15 mins
1min- 60÷15= 4 mins
therefore, your answer is D. 4km/min

Light of wavelength 525 nm passes through a double slit, and makes its second maximum (m = 2) at an angle of 0.482 deg. What is the separation of the slits , d, IN MILLIMETERS ?
Answer:
d = 0.124 mm
Explanation:
It is given that,
Wavelength of light is 525 nm
It makes second maximum at an angle of 0.482 degrees
We need to find the separation of the slits.
For 2nd maximum, the equation for double slip experiment is given by :
[tex]d\sin\theta=n\lambda[/tex]
d = separation of the slits
[tex]d=\dfrac{n\lambda}{\sin\theta}\\\\d=\dfrac{2\times 525\times 10^{-9}}{\sin(0.482)}\\\\d=0.124\ mm[/tex]
So, the separation of the slits is 0.124 mm.
Answer: 0.124

Answer:
D 15m/s
Explanation:
1)you find the speed covered in all the points e.g on speed=distance covered
time taken
a)300m\15s=20m/s
b)rest no distance covered
c)(1000-300)=700m time=(60-35)=25. 700m/25s=28m/s
d)(1200-1000)=300m time=(80-60)=20s
200m/20s=10m/s
thus the lowest speed was 10m/s at D
Average speed=average distance
average time
=1200m/80s. =15m/s

When leaving a fish tank, a ray moving at 31.0 deg in glass (n = 1.50) exits into the air. At what angle does it enter the air?
Answer:
50.5
Explanation:
Using Snell's Law, you can rearrange the equation to solve for the 2nd angle. The most important part of this question is remembering to use the 1.50 n in the numerator and 1.00n in the denominator. The reason for this is because 1.50's degree is already found: 31.0. You're looking for the degree where the ray hits air, which would be the 1.00 n. So, the equation looks like this: Sin^-1 (1.50sin(31)/ 1.00). After solving the equation, you get 50.5 or 50.6 if you round up. I hope this was helpful! :)

The special relativity hypothesis is accepted by all physicists. Even our satellites in orbit must synchronize their clocks and transmissions with those on Earth using Einstein's calculations.
What Einstein’s special theory of relativity?According to special relativity, speed has an impact on space, time, and mass. Small amounts of mass (m) can be interchangeable with vast amounts of energy (E), as indicated by the classic equation E = mc2. This method of defining the link between energy and matter is included in the theory.
Therefore, The relationship between speed, mass, time, and space is described by Einstein's special relativity theory. It describes the equation e=mc2, which asserts that energy is equal to mass times the square of the speed of light.
