The __________ is located under the forebrain and midbrain. A. forebrain B. midbrain C. hindbrain D. brainstem
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.

A cyclist is travelling at 4.0 m/s. She speeds up to 16 m/s in a time of 5.6 s. Calculate her acceleration.
Answer:
acceleration: 2.14 m/s²
Explanation:
acceleration = (final velocity - initial velocity ) ÷ time taken
Here the final velocity is 16 m/s, initial velocity is 4 m/s, time taken is 5.6 s
acceleration = ( 16 - 4 ) ÷ 5.6
→ 12 ÷ 5.6
→ [tex]\left[\begin{array}{ccc}\frac{15}{7}\end{array}\right][/tex] m/s² or 2.14 m/s²

A car with a mass of 1,600 kg has a
kinetic energy of 125,000 J. How fast is it moving?
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

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
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
If you view an object with binoculars, and the image appears right side up and a dozen times larger, then what is the magnification of the binoculars?
12 x is the magnification power if we view an object with binoculars, and the image appears right side up and a dozen times larger.
What is magnification power?Magnification power refers to the larger image of a given lens can make of an object which is seen through the lens. If a microscope has magnification power up to 1000x, then this means that the image of the object is 1000 times larger than the original one so we can conclude that the magnification power of binocular is 12x.

How does gravity cause the planets to move in a circle around the sun?.
Answer:
The sun's gravity pulls the planet toward the sun, which changes the straight line of direction into a curve. This keeps the planet moving in an orbit around the sun. Because of the sun's gravitational pull, all the planets in our solar system orbit around it.

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.
Happy to help!
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.

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
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).

why a bulb contains coiled wire?
Answer:
The filament is coiled to give it greater length. If the filament was just a piece of straight wire it would only give out a small amount of light. By curling the wire into a coil, a very long length of wire can be stored in a small space. When electricity flows through the coil it can give out much more light.

A 500-ml sample of argon at 800 torr has its absolute temperature quadrupled. If the volume remains unchanged what is the new pressure?.
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)
