A car with a mass of 1,600 kg has a
kinetic energy of 125,000 J. How fast is it moving?
Answers
Answer:
Hope This will help you
From the calculation, the kinetic energy of the moving car is 12.5 m/s.
What is kinetic energy?The term kinetic energy refers to the energy that a body possesses as a result of its motion. It is the energy of a moving body.
Now we know that the kinetic energy is 125,000 J and the mass is 1,600 kg. Now;
KE = 1.2 mv^2
v = √2KE/m
v = √ 2 * 125000/1600
v = 12.5 m/s

Because you already have the wavelength and the frequency, you just need to solve for velocity. You can do this by multiplying each side of the equation by frequency.
Therefore, 400 x 2.5 = 1000m/s.

A 500-ml sample of argon at 800 torr has its absolute temperature quadrupled. If the volume remains unchanged what is the new pressure?.
Answers
Answer
P V = C R T natural gas law
P1 V1 = C R T1
P2 / P1 = T2 / T1 = 4 other numbers remain constant and cancel
P2 = 4 P1
The new pressure is 4 times as great.
The new pressure is 4 times greater.
Argon:The chemical element argon has the atomic number 18 and the symbol Ar. It is a noble gas that belongs to group 18 of the periodic table.At 0.934 percent, argon is the third-most abundant gas in the Earth's atmosphere (9340 ppmv). It is 23 times as abundant as carbon dioxide (400 ppmv), more than 500 times as abundant as neon, and more than twice as abundant as water vapor, which averages around 4000 ppmv but varies substantially (18 ppmv). The most prevalent noble gas in the crust of the Earth, argon makes up 0.00015 percent of the crust.Torr:The torr is an absolute scale pressure measurement that is equal to precisely [tex]\frac{1}{760}[/tex] of a standard atmosphere. As a result, [tex]\frac{101325}{760}[/tex] pascals is exactly one torr. Although historically one torr was meant to be equivalent to one "millimeter of mercury," later redefinitions of the two units resulted in a minor difference.Solution -
[tex]PV=CRT[/tex] (Natural gas law)
[tex]P1V1=CRT1[/tex]
[tex]\frac{P2}{P1} =\frac{T2}{T1} =4[/tex] (Other members remain constant and cancel)

A ball of mass 1.84 kg is dropped from a height y, =
1.49 m and then bounces back up to a height of y, = 0.87 m.
How much mechanical energy is lost in the bounce?
Help
Answers
Answer:
11.408 joules
Explanation:
soln
From the question above
Mass of ball = m = 1.84kg
Height of ball when dropped = 1.49m
Height of ball when it bounces back up = 0.87m
Recall
Potential energy (P.E) = mass × height × g
Kinetic energy(K.E) = 1/2 × mass × (velocity)²
Mechanical energy = K.E + P.E
M.E lost = M.E when ball dropped – M.E when ball bounces back up
Recall that g = acceleration due to gravity = 10ms²
P.E/K.E when ball dropped = 1.84 × 1.49 × 10
P.E/K.E when ball dropped = 27.416J
P.E/K.E when ball bounces back = 1.84 × 0.87 × 10
P.E /K.Ewhen ball bounces back = 16.008J
Since P.E = K.E
M.E when ball dropped = 27.416J
M.E when ball bounces back = 16.008J
Therefore,
M.E lost = 27.416 - 16.008
M.E lost = 11.408Joules
The __________ is located under the forebrain and midbrain. A. forebrain B. midbrain C. hindbrain D. brainstem
Answers
Answer is the hind brain
The brainstem is located under the forebrain and midbrain. Therefore option D is correct.
The brainstem is located under both the forebrain and midbrain. It is a vital component of the central nervous system that connects the brain to the spinal cord and controls many essential functions such as breathing, heart rate, and digestion.
It consists of three main regions: the medulla oblongata, pons, and midbrain. The forebrain, midbrain, and hindbrain together constitute the major divisions of the brain.
The hindbrain is positioned below the midbrain and includes structures like the cerebellum, pons, and medulla oblongata.
The brainstem, specifically its lower regions, is responsible for relaying information between the brain and the rest of the body while regulating critical bodily functions.
Therefore option D is correct.

The resultant force is the overall force. If two forces are acting in the same direction, the resultant force is the sum of all the forces. Hence the blanks where r and s are resultant force and sum respectively.
What is force?Force is an external factor, which aids a body to change from the state of motion or rest. There are different types of forces namely, magnetic force, gravitational force, nuclear force, frictional force etc.
The unit of force is newton. According to Newton's second law of motion, the force acting on a body is the product of its mass and acceleration. Thus we have the equation F = ma.
If a body experience's different forces or the same forces in different direction the net force in after all balancing is called the resultant force.
Now, if two forces are acting on the same direction, the resultant force will be the sum of these forces.
Therefore, the blanks in the place of r and s are resultant and sum respectively.

The most recent information you can get about this star is near 10 years old.
What is a light-year?A light-year is a distance unit, that represents the distance that light can travel in one year.
Now, we know that nothing can move faster than the speed of light, and the only information that we can get about this star comes through light (electromagnetic waves). And these waves travel at the speed of light.
So these waves would need at least 10 years to travel from the start to the satellites that can detect them, this means that the most recent information that you can get about this star is actually 10 years old.

An object in projectile motion will follow which path?
curved up from the ground
curved down toward the ground
straight down toward the ground
straight up from the ground
Answers
An object in projectile motion will follow curved up from the ground, curved down toward the ground. The correct options are (a) and (b).
An object in projectile motion will follow a curved path. Specifically, it will follow a curved trajectory that is symmetric around the highest point of its flight. The object will initially move horizontally while also experiencing vertical motion due to the force of gravity. As a result, the object's path will be a parabolic curve.
So, the correct answer is Curved up from the ground (when initially launched) and curved down toward the ground (when it reaches the highest point and descends). The correct options are (a) and (b).

Height = h = 10m
Acceleration due to gravity = g = 9.8ms²
K.E = 1/2 × mass × (velocity)²
Recall from equations of motion
v² = u² + 2gh
Therefore,
K.E = 1/2 × mass × ( u² + 2gh)
K.E = 1/2 × 5 × ( 0² + 2×10×9.8)
K.E = 1/2 × 5 × 196
K.E = 1/2 × 980
