a subway train starts from rest at a station and accelerates at a rate of 1.60 m/s2 for 14.0 s. it runs at constant speed for 70.0 s and slows down at a rate of 3.50 m/s2 until it stops at the next station.
The presented statement estimates that the subway train traveled a total of 1798.18 meters.
What is the straightforward meaning of speed?The degree which an object's positioning changes in any direction. The inverse of the distance reached to the time needed to travel that distance is known as speed. Given that it only has to have a direction and no magnitude, tempo is a synthesis number.
initial acceleration (a1)= 1.60m/s^2
time (t1) = 14s
time for constant speed = 70s
deceleration (a2) = 3.50 m/s^2
total distance = ?
Velocity - Time Graph
We need to create the velocity-time graph in order to adequately address this problem.
By summing the separate areas of the figures, the distance may be computed.
Area of first triangle.
1/2b*h
However, this train's speed would be indicated by its height.
Velocity = acceleration * time
Velocity = 1.6 * 14 = 22.4m/s
The triangular is 22.4 meters tall.
Let's swap the variables and calculate the area.
A1 = 1/2*14*22.4 = 157.5m
The perimeter of the rectangle is the following distance that we would measure.
A = L*W
L = 22.4
W = 70
A = 22.4 * 70 = 1568m
The last triangle is the distance that has to be calculated.
Triangle area is equal to 1/2b*h.
However, we are unsure exactly how long the slowdown took on a base (time) basis.
Use the link between velocity, acceleration, and time.
Acceleration = velocity/time
time = velocity/acceleration
time = 22.4/3.5
time = 6.4s
Replace the values and find the Area by substituting
A = 1/2*b*h
A = 1/2 *6.4*22.4
A = 72.68m
The train travels a total of 157.5m Plus 1568m + 72.68m.
Distance = 157.5 + 1568 + 72.68
Distance = 1798.18m

if the pressure amplitude were increased by a factor of 10.0, what would the new sound intensity level be?
The new sound intensity level, L', will be 20 dB higher than the original sound intensity level, L. The sound intensity level, L, is a measure of the sound wave's power per unit area, relative to a reference value. It is expressed in decibels (dB).
The sound intensity level, L, is defined as 10 log (I/I0), where I is the intensity of the sound wave and I0 is the reference intensity. To find the new sound intensity level if the pressure amplitude is increased by a factor of 10.0, we first need to find the new intensity of the sound wave.
The sound intensity, I, is proportional to the square of the pressure amplitude, P:
I ∝ P²
So if the pressure amplitude is increased by a factor of 10.0, the intensity will be increased by a factor of 10.0² = 100.0. The new intensity, I', is given by:
I' = 100.0I
Using this new intensity, we can find the new sound intensity level:
L' = 10 log (I'/I0) = 10 log (100.0I/I0) = 10 log (100.0) + 10 log (I/I0) = 20 + L
So the new sound intensity level, L', will be 20 dB higher than the original sound intensity level, L.
In this calculation, we use the fact that log (ab) = log a + log b, where a and b are positive numbers.
So, if the pressure amplitude were increased by a factor of 10, the new sound intensity level would be 20 dB higher than the original sound intensity level. This relationship between pressure amplitude, intensity, and sound intensity level is important for understanding the physical properties of sound waves and for comparing the strength of different sounds.

From the ground, a ball is hurled straight up. A 2-m-high window is passed by it. The ball's starting velocity is 4.82 m/s because the bottom of the window is 7.5 metres above the ground.
What does level ground mean?Level ground refers to the lowest level of a structure when the majority of its height is exposed above the ground level of the nearby street or riverwalk. The floor that is level with the ground is referred to as the first floor in American English, followed by the floor that is above it and so on. The term "Ground Level" refers to the height of the main construction entrance to the structure or building.
What are ground level activities?Walking, slipping, tripping, transfers (such as getting up from a chair or bed), falling from furniture (such as a bed or sofa), picking something up off the ground, and standing tasks were all considered to be ground level activities (e.g., washing dishes).
We can employ the kinematic equation to get the ball's starting velocity:
h = vi * t + 0.5 * a * t^2
where an is the acceleration brought on by gravity (-9.8 m/s2), vi is the initial velocity, t is the time (1.3 s), and h is the window's height (2 m).
Rearranging the equation to solve for vi:
vi = sqrt(2 * a * h / t^2)
Substituting the values:
vi = sqrt(2 * (-9.8) * 2 / 1.3^2)
= sqrt(39.2 / 1.69)
= sqrt(23.18)
= 4.82 m/s
Therefore, the ball's initial velocity is roughly 4.82 m/s.

a hall probe gives a reading of \(1.5\mu v\) for a current of 2 a when it is placed in a magnetic field of 1 t. what is the magnetic field in a region where the reading is for 1.7 a of current?
The magnetic field in the region where the reading is for 1.7 A of current is 3.4 T.
The voltage produced by a Hall probe is proportional to the product of the magnetic field, the current, and a constant known as the Hall coefficient, denoted by "R_H". Mathematically, the relationship can be expressed as:
V = R_H * I * B
Where V is the voltage, I is the current, and B is the magnetic field.
We know the Hall coefficient and the magnetic field for a current of 2 A:
V = 1.5 * 10^(-6) V
R_H = V / (I * B) = 1.5 * 10^(-6) V / (2 A * 1 T)
Next, we can use the value of the Hall coefficient to find the magnetic field for a current of 1.7 A:
B = V / (R_H * I) = 1.5 * 10^(-6) V / (R_H * 1.7 A)
B = (1.5 * 10^(-6) V) / (R_H * 1.7 A) = (1.5 * 10^(-6) V) / (V / (2 A * 1 T) * 1.7 A)
B = (1.5 * 10^(-6) * 2 * 1 * 1.7) / (10^(-6)) = 2 * 1.7 T = 3.4 T
A magnetic field is a force field that is created by a magnetic object or a current-carrying conductor. It is an invisible field that exerts a force on charged particles in motion and causes them to move in a circular path around the magnetic object or conductor. The direction of the magnetic field is determined by the right-hand rule, which states that if you point your thumb in the direction of the current flow and your fingers in the direction of the magnetic field, your thumb will be pointing in the direction of the north pole of the magnetic object.
The strength of the magnetic field is measured in units of Tesla (T) or Gauss (G). A magnetic field is a vector area, which means that it has both significance and path. The magnetic field can interact with other magnetic fields, causing them to attract or repel each other.
Magnetic fields have many practical applications, such as in electric motors, generators, and MRI machines.

The escape speed of an electron launched from the surface of the sphere comes out to be approximately 1.6 x 10^6 m/s.
The escape speed of an electron launched from the surface of a charged sphere can be calculated using the following equation:
v_escape = sqrt(2 * k * q / m)
where k is Coulomb's constant,
q is the charge on the sphere,
and m is the mass of the electron.
For a glass sphere with a diameter of 1.4 cm charged to 10 nC,
the charge on the sphere can be calculated as follows:
q = 4 * pi * epsilon_0 * R * V
where epsilon_0 is the vacuum permittivity,
R is the radius of the sphere, and
V is the potential difference.
The radius of the sphere can be calculated as
R = 0.7 cm.

the behavior when the rocks elastically snap back to their previous dimensions with the release of associated stress accompanied with sudden displacement is called
The "elasticity rebound concept" of earthquakes refers to this steady buildup and releasing of stress and strain. The abrupt elastic rebounding of already stored energy is what causes most earthquakes.
What happens after an earthquake when a rock returns to its natural, stress-free form?Until the stress is so high that the rocks unexpectedly slip past one another, portions of a fault stay locked. An earthquake's shaking and vibrations are brought on by this slippage. Elastic rebound leads to earthquakes. Rock that has been elastically distorted suddenly returns to its original shape.
How would you characterise the reactions of rocks under various stresses?Rock can deform under stress in three different ways: elastically, plastically, or through breaking or fracturing. Similar to a rubber band that returns to its original shape when tension is released, elastic strain is reversible.

which net pressure draws fluid into the capillary?
a ball starts from rest and accelerates at 0.495 m/s2 while moving down an inclined plane 9.85 m long. when it reaches the bottom, the ball rolls up another plane, where, after moving 13.4 m, it comes to rest. what is the speed of the ball at the bottom of the first plane?
The speed of the ball at the bottom of the first plane is 1.67 m/s
The speed of the ball at the bottom of the first plane can be calculated using the kinematic equation:
v = v0 + at
Where v is the final velocity (speed), v0 is the initial velocity (0 m/s since the ball started from rest), a is the acceleration (0.495 m/s^2), and t is the time elapsed. To find the time elapsed, we can use the distance traveled and the acceleration:
d = v0t + 0.5at^2
Rearranging for time and substituting the values, we get:
t = sqrt(2d/a) = sqrt(2 * 9.85 m / 0.495 m/s^2) = 3.36 s
Now that we have the time elapsed, we can use the kinematic equation to find the velocity:
v = v0 + at = 0 m/s + (0.495 m/s^2) * (3.36 s) = 1.67 m/s
