Which graph represents a car with positive acceleration? Group of answer choices B A C D
The one that represents a car with positive acceleration is graph number III.
What is velocity?The term velocity has to do with the change of displacement with time. The acceleration is the change in velocity with time. We know that the slope of the velocity time graph is the acceleration. Uniform velocity occurs when the displacement increases in equal amounts in equal time intervals thereby leading to a straight line graph.
Hence a positive acceleration is only possible when the velocity is increasing in equal amounts in equal time intervals

A reconnaissance plane flies 545 km away from
its base at 568 m/s, then flies back to its base
at 852 m/s.
What is its average speed?
Answer in units of m/s.
Considering the definition of speed, the average speed of the plane is 681.6 m/s.
Speedspeed is a quantity that expresses the relationship between the space traveled by an object.
In other words, speed can be defined as the amount of space traveled per unit of time with which a body moves and can be calculated using the expression:
speed= distance traveled÷ time
Average speed in this caseIn this case, you know:
Part 1 of the trip: A reconnaissance plane flies 545 km (545,000 m) away from its base at 568 m/s, Part 2 of the trip: The reconnaissance plane flies back to its base at 852 m/s.So, in both cases you know the distance traveled and the speed. Therefore, you must calculate the time in which each part of the trip is made, in order to later know the total time. For this, the definition of speed is used:
Part 1 of the trip: 568 m/s= ÷ time → 568 m/s× time= 545,000 m → time= 545,000 m÷ 568 m/s → time= 959.5070 sPart 2 of the trip: 852 m/s= 545,000 m÷ time → 852 m/s× time= 545,000 m → time= 545,000 m÷ 852 m/s → time= 639.6714 sSo, you know:
total distance traveled= 545,000 m + 545,000 m= 1,090,000 mtotal time= 959.5070 s + 639.6714 s= 1599.1784 sReplacing in the definition of speed:
speed= 1,090,000 m÷ 1599,1784 s
speed= 681.6 m/s

D. Closed Universe Model
Option D) is the correct answer. The Closed Universe model of the fate of the universe, if correct, is most likely to predict a second Big Bang.
The Closed Universe Model describes a hypothetically ever-expanding universe that contains a sufficient amount of matter in it a so that the gravitational pull due to the stored mass is enough to reverse the observable expansion of the universe through its gravitational contraction.
It is predicted that according to this model, the closed universe will folds back on itself like a saddle.
This could result in a second Big Bang.
According to Albert Einstein, the general shape of the universe depends upon the average density of matter and energy in the universe. For a closed universe, the ratio of average density to critical density ( for which the universe is flat) is more than one.

A bush pilot wants to fly her plane to a lake that is 250.0 km [N30.0°E] from her starting point. The plane has an air speed of 210.0 km/h, and a wind is blowing from the west at 40.0 km/h. (a) In what direction should she head the plane to fly directly to the lake? (b) If she uses the heading determined in (a), what will be her velocity relative to the ground? (c) How long will it take her to reach her destination?
(a) The plane must fly at an angle of N 35.5° E to immediately approach the lake.
(b) The velocity of the plane is 245.6 km/h.
(c) The time taken is 1.02 hours.
Lake displacement from the starting position, D = 250 km N 30° E
As the x-axis, let's choose the line connecting the plane's beginning point with the lake, which is located in the direction N 30° E.
D = 250 ^i km
The plane's airspeed,
v(p) = 210 km/h
From the east comes the wind. Therefore, using the coordinate system described above, the wind speed,
v(w) = 40 [ cos ( − 30° ) ^i + sin ( − 30°) ] km/h
v(w) ≈ ( 36.64 ^i − 20 ^j ) km/h
(a) To eliminate the perpendicular component of the wind velocity, move the plane in the direction θ with respect to the x-axis.
v(p) = 210 ( cos(θ) ^i + sin(θ) ^j ) km/h
In order for the y-component of the plane velocity to cancel out the y-component of the wind velocity, the correct angle must be calculated.
Therefore,
210 sin(θ) km/h = 20 km/h
sin(θ) = 20 / 210
θ ≈ 5.5°
Therefore, the aircraft should fly 5.5 degrees off of the x-axis. This means that the plane must fly at an angle of N 35.5° E to immediately approach the lake.
(b) The velocity relative to the ground is:
v = v(w) + v(p)
v = 210 ( cos 5.5° ^i + sin 5.5° ^j ) km/h + ( 36.64 ^i − 20 ^j ) km/h
v ≈ ( 209 ^i + 20 ^j ) km/h + ( 36.64 ^i − 20 ^j ) km/h
v = 245.6 ^i km/h
The plane is moving at a speed of 245.6 km/h relative to the ground.
(c) From the starting point, the time taken to reach the lake is:
time = distance/ speed
T = 250 km / 245.6 km/h
T ≈ 1.02 h
Therefore, from the starting position, it will take around an hour to get to the lake.

A stone that is thrown with an initial velocity of 7.0 m/s and the acceleration of the stone is constant and has the value of -9.8 m/s2, then the velocity of the stone is 2.1 m/s
How to calculate velocity?The vector quantity of velocity (v) can be denoted by the equation v = s/t. This also quantifies displacement (or change in position, s), over the change in time (t). Speed (or rate, r) is a scalar number, denoted by the equation r = d/t, that quantifies the distance travelled (d) over the change in time (t).
Here are the three equations:
S = ut + 1/2at^2,
v = u + at,
v^2 = u^2 + 2as.
The data obtained from the question is:
Initial velocity (u) = 7 m/s
Time (t) = 0.50 s
Final velocity (v) =?
Since the stone is thrown upward, it means that this stone is going in a direction against gravity.
Thus, the value of the acceleration due to gravity will be found out in negative i.e – 9.8 m/s²
Thus, we can obtain the final velocity of the stone after time 0.50 s as follows:
Initial velocity (u) = 7 m/s
Time (t) = 0.50 s
Acceleration because to gravity (g) = – 9.8 m/s²
Final velocity (v) =?
v = u + gt
v = 7+(– 9.8 × 0.5)
v = 7 – 4.9
v = 2.1 m/s
Therefore, the final velocity of the stone calculated after 0.5 s is 2.1 m/s.

The magnitude of f is 232 newtons and it points at 184o measured counterclockwise from the positive x-axis. what is the y component (in newtons) of f?
By the vector, the force in the y component is -16.18 newtons.
We need to know about vectors to solve this problem. Vector has magnitude and also direction. Force is included in the vector. It can be written as
F = Fx i + Fy j + Fz k
where s is displacement, Fx is force on x-axis, Fy is displacement on y-axis and Fz is displacement on z-axis.
From the question above, we know that
|F| = 232 N
θ = 184⁰
The force on y-axis is
Fy = |F| . sin(θ)
Fy = 232 . sin(184)
Fy = -16.18 newtons
The negative force is caused by the direction of the force.

Two airplanes leave an airport at the same
time. The velocity of the first airplane is
700 m/h at a heading of 69.8°. The velocity
of the second is 620 m/h at a heading of 107.
How far apart are they after 1.9 h?
Answer in units of m.
Answer:
V1 = 700 cos 69.8 i + 700 sin 69.8 j vector components of V1
V1 = 241.7 i + 656.9 j in miles/hour
V2 = 620 cos 107 i + 620 sin 107 j
V2 = -181.3 i + 592.9 j
V = V1 - V2 = 423 i + 64 j rate of planes separation
1.9 V = 803.7 i + 121.6 j miles separation of planes after 1.9 hr
D = (803.7^2 + 121.6^2)^1/2 = 812.8 miles

An object is dropped from rest at a height of 127 m. find the distance it falls during its final second in the air.
The object will fall a distance during its final second in the air of: 81.967 m
The free fall formulas and the procedures we will use are:
t = √[ (2*h) / g]h = (g * t²)/2Where:
t = time takenh = height traveledg = acceleration due to gravityInformation of the problem:
h = 127 mg = 9.8 m/s²t = ?h(final second)= ?Applying the time formula we get:
t = √[ (2*h) / g]
t = √[ (2* 127 m) / 9.8 m/s²]
t = √[ 254 m / 9.8 m/s²]
t = √[ 25.918 s²]
t = 5.090 s
Calculating time traveled before the final second and we have:
t(final second) = t - 1 s
t(final second) = 5.090 s - 1 s
t(final second) = 4.090 s
Applying the height formula we get:
h = (g * t²)/2
h(final second) = (9.8 m/s² * (4.090 s)²)/2
h(final second) = (9.8 m/s² * 16.7281 s²)/2
h(final second) = 163.935 m/2
h(final second) = 81.967 m
What is free fall?It is when the object or mobile falls from a height (h) with a positive acceleration equal to the gravity, describing a vertical rectilinear travel.
