In a science fiction novel two enemies, Bonzo and Ender, are fighting in outer spce. From stationary positions, they push against each other. Bonzo flies off with a velocity of +1.8 m/s, while Ender recoils with a velocity of -2.6 m/s. Determine the ratio mBonzo/mEnder of the masses of these two enemies.
Answer:
Explanation:
Conservation of momentum
Initial momentum is zero
mB(1.8) + mE(-2.6) = 0
mB(1.8) = mE(2.6)
mB/mE = 2.6/1.8

The muscular system consists of exclusively this kind of tissue.
Answer:B
Explanation:
Each muscle or organ is composed of skeletal muscle tissue, connective tissue, nerve tissue, and blood or vascular tissue. Thus, the muscular system consists of all types of tissue.
What is the muscular system?The Muscle fibers are specialized cells that make up the muscular system. Its ability to contract is its main characteristic. Muscles that are attached to bones, internal organs, or blood arteries are what move things. Muscle contraction is the primary cause of almost all bodily movement. A skeletal muscle on its whole is a part of the muscular system.
Muscle cells, also known as muscle fibers or monocytes (mostly in skeletal and cardiac muscle), make up the majority of the organs that make up muscles (mainly in smooth muscle).
By contracting and pushing food to the small intestine through a process known as peristalsis, the muscles surrounding the stomach aid in the flow of food through the digestive system.

FIGURE 1 shows a 10 kg uniform metal rod with 2.0 m long pivoted at its centre C. A 20 N force is exerted on the rod, 0.5 m from point C. If the rod is in equilibrium, determine the
a) force, F needed.
b) magnitude and the direction of the force exerted at point C.
Answer:
Explanation:
Assuming we are looking parallel to a horizontal pivot pin with positive UP to the top of the picture, and the 20 N force acts perpendicular to the rod.
Sum moments about C to zero assume CW is the positive moment.
The rod mass causes no moment because there is no moment arm about C.
Fsin50[1.0} - 20[0.5] = 0
F = 10/sin50
F = 13 N
Summing vertical forces to zero With R being the pin reaction at C
Ry - F - 20sin50 - mg = 0
Ry = 13 + 20sin50 + 10(9.8)
Ry = 126.32 N
Summing horizontal forces to zero assuming a right directed force is positive.
Rx + 20cos50 = 0
Rx = -12.855...
R = √(-12.855² + 126.32²) = 126.972
R = 127 N
θ =arctan(126.32/-12.855) = 95.8107... = 5.8° CCW from UP

While you push a box you begin to decrease the force you are exerting on the box. When will the box reach equilibrium?
A. When the force you are exerting on the box is equal to 0.
B. When Fyou on box = -Fbox on you.
C. When the force of the box becomes Fyou on box < Fbox on you
D. The box will never reach equilibrium.
The application of a force on the box overcomes the friction and causes the box to accelerate
While the force is decreasing, the box will stabilize;
B. When [tex]\underline{F_{you \, on \, box} = -F_{box \, on \, you}}[/tex]Reason:
Newton's third Law of Motion states that action and reaction are equal in magnitude and opposite in direction
When the box is pushed with a force, [tex]F_{you \, on \, box}[/tex], the reaction of the box of mass, m, is as follows;
[tex]F_{you \, on \, box}[/tex] = [tex]F_{friction}[/tex] + m × accelerationWhere;
[tex]F_{friction}[/tex] = [tex]-F_{box}[/tex] for example
The negative sign is due to the direction of the friction force, or [tex]F_{box}[/tex] is opposite to the direction of the applied force
When the force is decreased to F₂ = [tex]F_{you \, on \, box}[/tex], such that we have;
[tex]F_{you \, on \, box}[/tex] = [tex]-F_{box \, on \, you}[/tex] , which is the condition for equilibrium, and the net
force is zero and according to Newton's first law of motion, the box moves
at constant speed no acceleration
Therefore the box will reach equilibrium when;

A 20-ohm resistor is connected to a 10 V battery. The 20-ohm resistor is replaced with a smaller resistor. What happens to the voltage across the resistor?
Explanation:
It is given that,
Resistance, R = 20 ohms
Voltage of the battery, V = 10 V
We can find current flowing through the circuit using Ohm's law as follows :
V = IR
\begin{gathered}I=\dfrac{V}{R}\\\\I=\dfrac{10}{20}\\\\I=0.5\ A\end{gathered}I=RVI=2010I=0.5 A
It can be seen from the Ohm's law, that the current is directly proportional to the voltage. It means that if the battery is replaced by a battery that provides a larger voltage, the current through the circuit will be more than 0.5 A i.e. it increases

The punter on a football team tries to kick a football so that it stays in the air for a long "hang
time". If the ball is kicked with an initial velocity of 30 m/s at an angle of 60 degrees above the
ground.
a. Calculate the "hang time".
b. How far does the ball go in the horizontal direction?
c. What is the maximum altitude (height) the ball reaches?
first resolve the initial velocity of the ball into two components
1)one parallel to ground(u)
2)another perpendicular to ground(v)
call the initial velocity=p=25.4 m/s at 58.0° deg to ground
so the horizontal component of velocity=25.4cos58=13.46 m/s
so the vertical component of velocity=25.4sin58=21.54 m/s
we have nothing to do with the horizontal component of velocity as it plays no part in the hang time
only vertical component of velocity determines the hang time
hang time=2*(vertical component of velocity)/(acceleration due to gravity)
==>hang time=2*21.54/9.8=4.39 s
==>hang time =4.39 s

Which of the following is TRUE regarding the development and growth of new neurons in the human brain?
A. The human brain has the capacity to generate new neurons throughout the lifespan.
B. There is no evidence that the human brain continues to develop new neurons after birth.
C. Glial cells of human brains continue to reproduce and grow in number through adulthood but neurons do not.
D. Animals such as primates, birds, and rodents do not experience neurogenesis
The human brain has the capacity to generate new neurons throughout the lifespan (option b).
The correct statement regarding the development and growth of new neurons in the human brain is option A. The human brain has the capacity to generate new neurons throughout the lifespan.
1. Neurogenesis, the process of generating new neurons, was once believed to be limited to early brain development and not to occur in adulthood. However, recent research has challenged this notion.
2. Studies conducted on adult brains have provided evidence of neurogenesis occurring in specific regions of the brain, such as the hippocampus, which is involved in learning and memory.
3. Neurogenesis in the adult brain involves the generation of new neurons from neural stem cells. These stem cells have the ability to differentiate into mature neurons and integrate into existing neural circuits.
4. The process of neurogenesis is influenced by various factors, including environmental enrichment, physical exercise, and certain medications.
5. It is important to note that while neurogenesis occurs in the adult human brain, the rate of neurogenesis is relatively low compared to early brain development.
6. In contrast to option B, there is evidence to support the idea that neurogenesis continues to occur in the human brain after birth and throughout life.
7. Option C is incorrect because while glial cells, a type of support cell in the brain, can reproduce and grow in number throughout adulthood, neurons also have the capacity to generate new neurons.
8. Option D is incorrect as several animal species, including primates, birds, and rodents, have been found to experience neurogenesis in various stages of their lives.
In conclusion, option A is the true statement regarding the development and growth of new neurons in the human brain, as neurogenesis can occur throughout the lifespan.
