Which of these sets of thesis-antithesis IS NOT appropriate according to the instructions given by your instructor because it is too broad?
Calculate the acceleration of the object as it slides down the incline plane.
Answer:
0.788 m/s²
Explanation:
Ff = 0.1 × 5 kg × 10 m/s² × cos 38°
Ff = 5 N × 0.788
Ff = 3.94 N
F = m × a
3.94 N = 5 kg × a
a = 3.94 N / 5 kg
a = 0.788 m/s²

Thermodynamics is the branch of physical science that deals with the relations between heat and other forms of energy (such as mechanical, electrical, or chemical energy), and, by extension, of the relationships between all forms of energy.
A plane flying due north at 191 mph encounters winds that blow the plane due east at 45 mph. Determine the plane's resultant velocity. Record your answers to the nearest tenth.
Answer:
Below
Explanation:
For these types of questions, you should draw out your triangles and resultant vectors.
For this, we can use the pythagorean theorem to solve this :
vpf^2 = vpi^2 + vw^2
vpf^2 = 45^2 + 191^2
vpf = [tex]\sqrt{38507[/tex]
vpf = 196.2294
vpf = 200 mph
Now we need to find the angle of the plane's direction using soh cah toa
Tan(x) = O / A
x = tan^-1(191/45)
x = 76.74
x = 77 degrees
Therefore, the plane's result velocity is 200 mph [ E 77 N ]

transformer is used in rectifier step up and step down voltage?
Answer:
While the use of the type of transformer in a rectifier depends on the voltage requirement or to meet desired operating conditions, a step-down transformer is used mainly to reduce the voltage. It is used to bring the high AC voltage level to a reasonable value or the desired output voltage.

A 5000 kg train is traveling at a velocity of 100 m/s and hits another train. The two trains stick together and the new velocity is 50m/s. What is the mass of the second train?
Answer:
Explanation:
Conservation of momentum is used to solve
Unfortunately we have a missing piece of information such as the initial velocity of the unknown mass train.
If we ASSUME that the second train is at rest
5000(100) + m(0) = 5000(50) + m(50)
which means m = 5000 kg
However, I'll show you the importance of knowing that initial velocity by finding it assuming the other answers are valid
if m = 15000 kg
5000(100) + 15000(v₀) = (5000 + 15000)(50)
v₀ = 33 ⅓ m/s
if m = 10000 kg
5000(100) + 10000(v₀) = (5000 + 10000)(50)
v₀ = 25 m/s
if m = 8000 kg
5000(100) + 8000(v₀) = (5000 + 8000)(50)
v₀ = 18.75 m/s
So you can see why I had to assume an initial velocity. Any of the masses could work if the initial velocity is chosen correctly.

If the static frictional coefficient is pls
0.74, what is the force of static friction?
=
Hi there!
We know that the MAXIMUM static friction force to be overcome is:
Fs (Force of Static Friction) = μN (Normal Force)
The normal force is equal to the weight of the block AND the vertical component of the applied force, so:
N = Mg + Fasinθ
Plug in the given values:
N = 26.8(9.81) + (89.2)sin(38) = 317.825 N
Multiply by the force of static friction to derive the static force:
0.74 * 317.825 = 325.191 N <-- MAXIMUM STATIC FRICTION FORCE
The force applied, if not greater than this value, will result in an EQUAL and OPPOSITE static frictional force. Thus:
Fs = Horizontal component of the applied force
Fs = 89.2cos(38) = 70.291 N

When do you know if Respect is being shown? If there is discrimination? Cite some indicators
Peace and violence are the indicators of the society.
Respect is shown if we see a people as a person and not as a toy. If we stop criticizing and judging by just looking at them than the other person also gives us respect which leads to peace and harmony in the society.
If there is discrimination and no respect of other people's feeling then there is violence and disharmony in the society so we can conclude that peace and violence are the indicators of the society.

PLEASE MARK AS BRAINLIEST!!!!!You attach a cart with a mass of 0.92 kg to a spring and compress the cart-
spring system. The spring constant for the spring is 130 N/m. Your objective is
to propel the cart with a velocity of 1.4 m/s along a frictionless surface. How
need to compress the spring in order to meet your target velocity?

you
Answer:
F = - K X force exerted by compressed spring
F X = 1/2 M V^2 energy (work) required to produce a speed V for mass M
K X * X = 1/2 M V^2 direction of F is the same as that of V
X^2 = M V^2 / K combining terms
X = (M / K)^1/2 V
X = (.92 / 130)^1/2 * 1.4 = .118 m

Explanation:
If you throw a ball up into the air and it reaches its original height after 6 seconds, calculate how high above its original position the ball reached. (Answer to two decimal places).
Explanation:
Assuming that there is no air resistance, the given time means that the ball reached its maximum height 3 seconds after throwing it upwards so we can solve its
maximum height by solving for [tex]v_{0y}[/tex] first:
[tex]v_y = v_{0y} - gt \Rightarrow v_{0y} = gt[/tex]
[tex]v_{0y} = (9.8\:\text{m/s}^2)(3\:\text{s}) = 29.4\:\text{m/s}[/tex]
Now that we know [tex]v_{0y},[/tex] we can now solve for [tex]y_{max}:[/tex]
[tex]y_{max} = v_{0y}t - \frac{1}{2}gt^2[/tex]
[tex]\:\:\:\:\:\:=(29.4\:\text{m/s})(3\:\text{s}) - \frac{1}{2}(9.8\:\text{m/s}^2)(3\:\text{s})^2[/tex]

Hanna tosses a ball straight up with enough speed to remain in the air for several seconds.
A: What is the velocity of the ball when it reaches its highest point?
B: What is its velocity 1 s before it reaches it’s highest point?
C: What is the change in its velocity during this 1-s interval?
D: What is its velocity 1 s after it reaches its highest point ?
E: What is the change in velocity during this 1 s interval?
F: What is the change in velocity during the two second interval?
G: what is the acceleration of the ball during any of these time intervals and the moment the ball has zero velocity?
Answer:
In the free fall motion we have that the acceleration is constant and produced by gravity, this acceleration has a magnitude of 32 ft/s2 or 9.8 m/s2 depending on the units you are working with. This means that every second the speed changes a magnitude of 32 ft/2, the velocity will depend of whether the ball is going upward (positive) or downward (negative).
A) At the highest point the ball stops to start the descend, here v=0 ft/s
B) +32 ft/s. The vector is going up, in the next second the velocity is going to be 0 (negative acceleration)
C) V=vf-vo=0-32=-32 ft/s is the constant change in velocity in projectile motion
D) -32 ft/s. The vector is pointing downward
E) V=vf-vo=-32-0=-32 ft/s is the constant change in velocity in projectile motion, 32 ft/s per second
F) Delta V=vf-vo=-32-32=-72 ft/s
g) gravity acceleration is constant 32 ft/s2 (pointing downward vector)
A350kg car is moving 16m/s north and collides with a 650kg truck going 11m/s east.if it lock bumpers,how fast and in what direction will they are going after the collision
Hi there!
We can begin by breaking the problem up into two directions, horizontal and vertical.
The collision is perfectly inelastic since the two objects stick, so:
1 = car
2 = truck
Momentum in the east direction (positive and horizontal, car NOT going in this direction has a velocity of 0 m/s):
m2v2 = (m1 + m2)v
(650 · 11) / (350 + 650) = 7.15 m/s
Momentum in the north directions (only initial is the northward velocity of the car):
m1v1 = (m1 + m2)v
(350 · 16)/(350 + 650) = 5.6 m/s
Find the overall velocity using the pythagorean theorem:
√(5.6²) + (7.15²) = 9.08 m/s
Find the direction using trigonometry. Use tangent in this situation:
tan Ф = O/A
tan⁻¹(5.6/7.15) = 38° north of east

3)They are made in stars.
4)They can only be seen by an electron microscope.
Answer:
4.
Explanation:
The characteristic of an atom is as follows:
They can only be seen by an electron microscope.Thus, the correct option for this question is D.
What do you mean by an Atom?An atom may be defined as a particle of matter that uniquely defines a chemical element. Each and every atom consists of a central nucleus that holds positively charged subatomic particles known as Protons along with neutrons.
Apart from protons and neutrons, the negatively charged subatomic particles known as electrons are always revolved around the nucleus of each atom in its orbitals.
According to the context of this question, an atom is the smallest unit of matter which significantly retain all the chemical properties of an element. Thus, the second option is eliminated. They are naturally present not made in stars. So, the option third is also eliminated.
Therefore, the correct option for this question is D.
