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.

A 5.0 kg flying squirrel is flying from a tree down to the ground at constant velocity. Consider air resistance. Diagram the forces acting on the squirrel
The free body diagram of the squirrel motion, the weight of the squirrel is acting downwards while the air resistance is acting upwards.
The given parameters;
mass of the squirrel, m = 5 kgacceleration due to gravity = 9.8 m/s²At a constant velocity downwards, the vertical acceleration is zero.
The downward force on the squirrel is calculated as follows;
W = mg - ma
W = m(g - a)
W = m(g - 0)
W = mg
W = 5 x 9.8
W = 49 N
The air resistance on the squirrel which is acting upwards is calculated as;
n = ma + mg
n = m(a + g)
n = m(0 + g)
n = mg
n = 5 x 9.8
n = 49 N
The free body diagram is presented below;
↑ n

↓ W
Thus, in the free body diagram of the squirrel motion, the weight of the squirrel is acting downwards while the air resistance is acting upwards.

1. Your big brother, despite warning, drops a penny off the observation
deck of the Empire State Building in New York City. The observation
deck is 381 m above the ground. What is the terminal velocity of the
penny? How far has the penny fallen after 3 seconds?
Answer:
The marble will take 8.813 seconds to hit the ground.
Explanation:
The marble will fall according to this motion equation: y(final) = y(initial) + v(initial)×t + 1/2×a×t×t
y(final)=0 m, the marble's final position in relation to the ground
y(initial)=381 m, the marble's initial position in relation to the ground
v(initial)=0 m/s (meters per second), the marble's initial velocity (speed with direction) when fall first begins
t=? seconds, this is the amount of time that passes while falling, the variable in this problem
a=-9.81 m/s/s, the rate at which the velocity of the marble changes, acceleration. On Earth, neglecting friction, acceleration is a constant at negative 9.81 meters per second squared
Plug the values into the equation: 0= 381 + 0t + 1/2(-9.81)(t)(t)
Subtract 381 from both sides and disregard 0t because it has no value and no longer matters: -381= 1/2(-9.81)(t)(t)
Multiply out the equation: -381= -4.905(t)(t)
Divide both sides by -4.905 to isolate the variable: 77.676=(t)(t)
Find the square root of both sides: t=8.813 seconds

What is Juan’s velocity between 0-5 seconds?
Juan’s velocity between 0-5 seconds would be 2 m/s, the slope of the position time graph represents the velocity of the object and between the 0-5 seconds slope of the line is 2.
What is Velocity?The total displacement covered by any object per unit of time is known as velocity. It depends on the magnitude as well as the direction of the moving object.
velocity= total displacement/Total time
As given in the problem we have to find the velocity of Juan between 0-5 seconds.
The displacement covered between 0-5 seconds is 10 meters.
the time taken to change position is 5 seconds,
the velocity of the Juan = 10/5
= 2 meters/seconds
Thus, its velocity of Juan comes out to be 2 meters/second.

how can you increase the sensitivity of a Mercury thermometer?
The sensitivity of a mercury thermometer can be increased by using a smaller mercury bulb, thinner wall and smaller bore. A smaller bulb contains less mercury and hence absorbs heat in shorter time. As a result it can response faster to temperature change.

What is the Validity measures of a basketball bouncing
This study was aimed at testing the construct validity of the basketball basic motion skills test instrument (ITK GDBB). The research used descriptive method of 3 basketball experts in the city of Cimahi; 3 experts are the expert in basketball. The instrument used was the ITB GDBB developed by Silvy (2019) consisting of top passing, bottom passing, top service, bottom service, chest passing, bounding passing, overhead passing, and leading ball (dribbling). This instrument consists of 76 items that cover 4 domains in basketball, namely chest pass, overhead pass, bound pass, and dribbling. The validity method used the construct validity of different power types. For the reliability method, it used the Kuder Ricardson (KR) and Objectivity analysis. The results of the construct validity analysis of a total of 76 items show that the score is ranged from 0.67 to 1.00. The construct validity value of 71 items in the basketball game is in the high category (= 1.00), 5 items are in the sufficient category, the relativity score is ranged from 0.75 to 0.98, and the objectivity score is ranged from 0.89 to 0.95. The conclusion is that this test instrument can be used as a standardized basic motion skill test for standardized large ball games for validity in basic motion skills in basketball games for grade VII junior high school students.
