Answer:
BASE jumping is the recreational sport of jumping from fixed objects, using a parachute to descend safely to the ground. "BASE" is an acronym that stands for four categories of fixed objects from which one can jump: building, antenna, span, and earth (cliff).[1][2] Participants exit from a fixed object such as a cliff, and after an optional freefall delay, deploy a parachute to slow their descent and land. A popular form of BASE jumping is wingsuit BASE jumping.
Explanation:
In contrast to other forms of parachuting, such as skydiving from airplanes, BASE jumps are performed from fixed objects which are generally much lower altitude, and BASE jumpers typically carry only one parachute. BASE jumping is significantly more hazardous than other forms of parachuting, and is widely considered to be one of the most dangerous extreme sports

While John is traveling along a straight inter-
state highway, he notices that the mile marker
reads 246 km. John travels until he reaches
the 147 km marker and then retraces his path
to the 172 km marker.
What is John's resultant displacement from
the 246 km marker?
Answer in units of km.
Answer:
74 km
Explanation:
Ler the position of markers be A,B, and C for notation 246 km, 172 km, and 147 km respectively. John's whole journey has been shown in the figure.
As given,his initial position was the point A. At first, he travelled from the point A to C, then he traveled back from the point C to B on the straight path. His final position is at the point B.
The resultant displacement equals to the shortest distance between the final and the initial positions.
So, the magnitude of the resultant displacement is |172-246| km=74 km and the direction is towards point B from point A.

A)What is the acceleration at 1 second?
Answer in units of m/s 2.
B) What is the velocity at 2 seconds?
Answer in units of m/s.
C) What is the position at 2 seconds?
Answer in units of m
Answer:
Acceleration at 1 second= 1.5m/s/s
Velocity at 2 seconds = 3m/s
Position at 2 seconds= 3 meters
Explanation:
s=1/2(v+u)t
S= displacement
V= final velocity
U= initial velocity
t= time
v= 3 m/s
u= 0 m/s
t= 2 seconds 3m/s/2=1.5m/s x2 s = 3 meters

The weight of an object can be described as the pull, or force, of gravity on it. This force is given by the mass of the
object times the acceleration due to gravity, F=mg. The acceleration due to gravity, g, is a constant with a value of
9.81 m/s?. Calculate the weight due to gravity in Newtons of an object that is 4.69 lbs.
A)
0.217 N
B)
11.5 N
20.9 N
Х
D)
46.0 N
Answer:
The answer is 46.0089 N of weight
Explanation:
The answer is in the question
F=mg
reverse the question, mg=F
Plug in the values of mass (4.69) and gravity (9.81)
4.69(9.81)=F
F = 46.0089 (or D)

Light enters water at an angle of incidence of 24 degrees and refractive index of 4/3.Calculate the angle of refraction
Explanation:
According to Snell's law :
Sin i / Sin r = refractive index
[tex]r = sin^{ - 1} ( \frac{sin \: i}{1.33} ) = sin^{ - 1} (0.3)[/tex]
[tex]angle \: of \: refraction = 17.45°[/tex]
Therefore, angle of refraction is less than angle of incidence because the light ray bends towards the normal when it travels from rarer to denser medium
An airplane accelerates with a constant rate of 3.0 m/s2
starting at a velocity of 21 m/s. If the final velocity is 60 m/s,
what is the displacement during this period?
Answer:527 m
Explanation:
The displacement or distance travelled by the airplane during the given period is 526.5m
Given the data in the question;
constant acceleration; [tex]a = 3.0m/s[/tex]
Initial velocity; [tex]u = 21m/s[/tex]
Final velocity; [tex]v = 60m/s[/tex]
Displacement or distance; [tex]s = ?[/tex]
To find the displacement or distance the plane has travelled during the given period, we use the Third Equation of Motion:
[tex]v^2 = u^2 + 2as[/tex]
Where v is the final velocity, u is the initial velocity, a is the acceleration and s is the displacement.
Lets make "s" the subject of the formula
[tex]s = \frac{v^2-u^2}{2a}[/tex]
We substitute our given values into the equation
[tex]s = \frac{(60m/s)^2 - (21m/s)^2}{2 \ *\ 3m/s^2} \\\\s = \frac{(3600m^2/s^2) - (441m^2/s^2)}{6m/s^2}\\\\s = \frac{3159m^2/s^2}{6m/s^2}\\\\s = 526.5m[/tex]
Therefore, The displacement or distance travelled by the airplane during the given period is 526.5m

7500 meters
150,000 meters
15 meters
150 meters
Answer:
7500 m
Explanation:
The speed is the same both directions, so the sound takes 5 seconds to reach the bottom and 5 seconds to return to the surface.
Distance = speed × time
d = (1500 m/s) (5 s)
d = 7500 m
Answer:

According to the kinetic theory, all matter is composed of _______.
Answer:
According to the kinetic theory, all matter is composed of _______.
Explanation:
The Kinetic Theory of Matter states that matter is composed of a large number of small particles, individual atoms or molecules, that are in constant motion. Matter is made up of particles that are constantly moving. All particles have energy, but the energy depending on the temperature of which matter is in.
According to the kinetic theory, all matter is composed of large number of identical small molecules.
What is kinetic theory of gases?
A lot of the fundamental ideas of thermodynamics were established with the help of the kinetic theory of gases, a straightforward yet historically significant classical model of the thermodynamic behavior of gases.
According to the model, a gas is made up of numerous identical submicroscopic particles (atoms or molecules) that are all moving rapidly and randomly.
It is considered that they are substantially smaller in size than the particle spacing on average. Random elastic collisions between the particles and with the container's walls occur between the particles. The simplest form of the model only takes into account the interactions within the ideal gas.

B. Only the mass of the planet
C. Your mass and the mass of the planet
D. The distance from the surface to the center of the planet
Answer: B. Only the mass of the planet
Explanation:
the confusion on the concepts of mass and weight arises from the fact that the acceleration due to gravity is more or less constant in any place on the Earth's surface, thus the weight of an object is directly proportional to its mass. hope it helps <3
A thin spherical shell with radius R1 = 4.00 cm is concentric with a larger thin spherical shell with radius R2 = 6.00 cm . Both shells are made of insulating material. The smaller shell has charge q1=+6.00nC distributed uniformly over its surface, and the larger shell has charge q2=−9.00nC distributed uniformly over its surface. Take the electric potential to be zero at an infinite distance from both shells.
Answer:
The right response will be "450 volts".
Explanation:
The given values are:
R1 = 4.00 cm
R2 = 6.00 cm
q1 = +6.00 nC
q2 = −9.00 nC
As we know,
The potential difference between the two shell's difference will be:
⇒ [tex]\Delta V=K[(\frac{q1}{R1}+\frac{q2}{R2})-(\frac{q1}{R1} +(\frac{q2}{R2}))][/tex]
[tex]=K[\frac{q1}{R2}-\frac{q1}{R1} ][/tex]
On substituting the values, we get
[tex]=(9\times 10^9)[\frac{6\times 10^{-9}}{0.04}-\frac{6\times 10^{-9}}{0.06}][/tex]
Δ [tex]=450 \ volts[/tex]

lithification is a process of:
a. melting igneous rock
b. eliminating spaces between grains
c. forming sedimentary rock
d. causing uplift
Lithification is a process of forming sedimentary rock. The correct option is D.
What do you mean by lithification?The challenging process of lithification converts loose silt grains that have recently been deposited into rock. Once a silt is deposited, lithification may occur immediately or later. Cementation is one of the crucial processes, particularly for sandstones and conglomerates.
What makes lithification significant?Fresh sediment is often a loose substance that has several pores or open holes that are either filled with air or water. Lithification works to fill in the reduced pore space with a mineral deposits substance. Compaction and cementation are the major lithification processes.

What evidence shows galaxies are moving away from us?
speed
blue shift
red shift
changes in light
Answer:
Redshift and blueshift describe how light shifts toward shorter or longer wavelengths as objects in space (such as stars or galaxies) move closer or farther away from us. The concept is key to charting the universe's expansion.
Visible light is a spectrum of colors, which is clear to anyone who has looked at a rainbow. When an object moves away from us, the light is shifted to the red end of the spectrum, as its wavelengths get longer. If an object moves closer, the light moves to the blue end of the spectrum, as its wavelengths get shorter hope this helps.
