Which of the following are conditions required for static equilibrium? Select TWO answers. Elimination Tool A Linear Momentum = →p=0. B:Angular Momentum = →L=0. C:Change in Energy = ΔEtotal=0. D: Net Force ≠0.
Answer:
The correct answers are Choices 'A' and 'B'.
Explanation:
The correct answers are Choices 'A' and 'B'.
Static equilibrium means that the object is not moving relative to a given frame of reference.
Choice 'A' Linear Momentum = →p=0
is required. "Not moving" means the velocity
v must be 0(otherwise the object would be moving across the reference frame), so an object's linear momentum (which is its mass times its velocity) must be 0.
Choice 'B' Angular Momentum = →L=0 is required. "Not moving" also means that the object can not be rotating or spinning inside the reference frame, which means the rotational velocity ω must be 0. So an object's angular momentum (which is its mass times its rotational velocity) must be 0 .
Choice 'C' Change in Energy is true (this is known as conservation of energy), but it is not a requirement of static equilibrium because "not moving" is not the same as "isolated."
There are many forms of energy, many of which are not related to movement. For example, a light bulb in a stationary lamp is in static equilibrium, but if the light is turned on .
Similarly, when you add gasoline to your car at a gas station, the car must be in static equilibrium, but the addition of the gasoline from outside the car changes the Total Energy of the car.
Choice 'D' Net Force ≠0 is a non-equilibrium condition because by Newton's second law of motion, so any non-zero net force will cause an acceleration, and acceleration is not a state of static (or dynamic) equilibrium.
Find the horizontal and vertical displacement comments of 145m displacement of a superhero that flies from the top of a building at an angle of 28 degrees below the horizontal
Answer:
The horizontal and vertical displacement is 128.02 m and 68.07 m respectively.
Explanation:
Displacement, d = 145 m
The top of a building at an angle of 28 degrees below the horizontal
We need to find the horizontal and vertical displacement.
For horizontal displacement,
[tex]D_x=d\cos\theta\\\\D_x=145\times \cos(28)\\\\D_x=128.02\ m[/tex]
For vertical displacement,
[tex]D_y=d\sin\theta\\\\D_y=145\times \sin(28)\\\\D_y=68.07\ m[/tex]
So, the horizontal and vertical displacement is 128.02 m and 68.07 m respectively.

7. A mass m1 of 250 g is on a table connected to a massless pulley, as shown. The coefficient of friction between m1 and the table is 0.228. What is the maximum value of m2 before m1 starts sliding across the table?
Answer:
The minimum mass of m2 before m1 starts sliding across the table is 57 grams
Explanation:
The given mass on the table, m1 = 250 g
The coefficient of friction between the table and the mass, m1, μ = 0.228
Therefore, the friction force, F[tex]_F[/tex] between the mass m1 and the table is given as follows;
F[tex]_F[/tex] = W₁ × μ
Where;
W₁ = The weight of m1 = Mass of m1 × Acceleration due to gravity
W₁ = 250 g × 9.81 m/s² = 0.25 kg × 9.81 m/s² = 2.4525 N
W₁ = 2.4525 N
Which gives;
F[tex]_F[/tex] = 2.4525 N × 0.228 = 0.55917 N
F[tex]_F[/tex] = 0.55917 N
By equilibrium of forces, the weight, W₂, of the mass m2 at which the mass m1 starts sliding is equal to the frictional force F[tex]_F[/tex] of m1 or 0.55917 N
Therefore, for slipping to occur, we have;
W₂ = 0.55917 N
However, W₂ = Mass of m2 × Acceleration due to gravity
∴ W₂ = 0.55917 N = m2 × 9.81 m/s²
0.55917 N = m2 × 9.81 m/s²
m2 = 0.55917 N/(9.81 m/s²) = 0.057 kg = 57 grams
The minimum mass of m2 before m1 starts sliding across the table is 57 grams.

What is part of the fourth stage in the process of technological design?
O rebuilding and retesting a product
O analyzing the results of a prototype
establishing criteria for a successful product
identifying and defining a problem or need
Answer:
It is A.
Explanation:
Got it right on Edge 2022.
Rebuilding and retesting a product is part of the fourth stage in the process of technological design, therefore the correct answer is option A.
What are the stages of technological design?There are mainly five stages of the technological design
Identifying the issue that needs to be solved is the first step in every problem-solving process.
The second stage is to imagine; during this phase, a designer would generate several concepts and conduct research on potential creations. They must pick a handful of their greatest concepts and then narrow it down to the best.
The chosen product from the imaging stage is planned in the third stage. This process involves designing and drawing the product so that it may be turned into a model or prototype while taking into account the constraints they have to deal with.
Testing, evaluating, and modifying the product are the fourth stage. The designer can determine what they appreciate about their product and what they could change by making a model or prototype of it. Through product testing, this is discovered. If adjustments are required, the designer will repeat the entire procedure until they are satisfied with the final result.
The sharing of your solution is the fifth step. To gather comments, discuss your ideas with others, and enhance your product, you showcase your solution. You might show your answer to a bigger audience in later stages after you've gone through the design process a few times. This is comparable to how World of Inquiry students modifies their homework numerous times before presenting them during the expedition.
Thus, Rebuilding and retesting a product is part of the fourth stage in the process of technological design, therefore the correct answer is option A.

Determine the total displacement of a dog that runs 15 m north, 6 m south, then 8 m north.
Answer:
the displacement Is 17m north
Explanation:
15-6=9
9+8=17
The total displacement of a dog that runs 15 meters north, 6 meters south, then 8 meters north would be 17 meters because displacement is measured by the shortest distance between the initial and final position of the moving object.
What is displacement?An object's position changes if it moves in relation to a reference frame, such as when a passenger moves to the back of an airplane or a professor moves to the right in relation to a whiteboard.
Displacement describes this shift in location.
Displacement is a vector quantity.
Since the displacement is determined by the smallest distance between the moving object's original and final positions, a dog traveling 15 meters north, 6 meters south, then 8 meters north would move a total of 17 meters.
Thus, the total displacement of the dog comes out to be 17 meters.

A college student walking on a sidewalk throws his keys to a friend on a balcony 6m above him. If the college student throws the keys upward at 9.4 m/sec, can his friend on the balcony catch the keys? If not, what distance will the keys reach?
true or false: forces have a magnitude and a direction
A ball is thrown straight up with a velocity of 16 m/s; what will be its velocity 2.0s after being released?
Answer:
The ball will be travelling downward with a speed of 9.8 m/s.
Explanation:
The ball will be travelling downward with a speed of 9.8 m/s.
Explanation:
The acceleration of the ball will be a constant
9.8 m s 2
(downward), regardless of whether the ball is travelling upward or downward.
The equation that makes this calculation simplest is
v f = v i − g ( Δ t )
where the negative sign has been used to account for the opposite directions of v i and g . After 3 seconds, v f = 19.6 − ( 9.8 ) ( 3 ) = 19.6 − 29.4 = − 9.8 m s
The negative result tells us that the ball is on its way downward by this time (consistent with our choice of a negative value for the downward acceleration of gravity).

In 1969 the Apollo astronauts left a laser reflector on the Moon. This was to be used to help scientists to make very accurate measurements of the distance between the Earth and the Moon. The mean distance between the centres of the Earth and Moon is 385 000 km, and light travels at 3 × 10⁸ m/s.
Answer:
I guess that you want to calculate the averae time that passes since you "fire" the laser, and you see the reflection.
We know that:
Distance = Time*Speed
Distance/speed = time.
In this case we have:
Distance = 385,000km
Speed = 3x10^8m/s
First, there are two corrections:
1) The distance to the moon is traveled two times, so the actual distance would be:
Distance = 2*385,000km = 770,000km
2) Both quantities should be written in the same units, so we can write the speed in kilometers:
We know that:
1km = 1000m
Then 3x10^8 m/s = (3x10^8/10^3) km/s = 3x10^(8 - 3) km/s = 3x10^5 km/s
Now we can solve the equation:
Time = 770,000km/(300,000 km/s) = 2.57 seconds.
