Answer:
A. 3,000,000 m
B. 0.25 km
C. 10 m
D. 1,000 cm
Explanation:
no hablo español, así que solo ingrese esto en el traductor de G*ogle
A. One kilometer equals 1000 meters, so
3,000*1,000 = 3,000,000 m
B. One meter equals 0.001 kilometer, so
250*0.001 = 0.25 km
C. One centimeter equals 0.01 meter
1,000*0.01 = 10 m
D. One milimeter equals 0.1 centimer, so
10,000*0.1 = 1,000

Explain how you would deal with these social changes you have I identified to counter any negative impact on your success as a student
Explanation:
It is necessary that the student is always focused on his / her greatest goal in his / her academic life. There are many students who aspire to enter a certain college, or to pursue a particular professional career. So my advice for facing social changes that can have a negative impact on your success as a student is to plan your future goals and ambitions, always be up to date with the demands of society, seek help if necessary and always dedicate yourself to the maximum in your studies.
To deal with the social changes that may result in negative impact, the student must be advised, encouraged and also seek psychological help if necessary.

Identify the electromagnets with poles that are reversed from the electromagnet shown above
I've attached a picture of the 3 electromagnets options below the main electromagnet.
Answer:
The third electromagnet is correct.
Explanation:
From the attached image, in the electromagnet above the 3, we can see that the positive terminal comes before the negative terminal at the bottom left.
Now, when it is reversed, they will both move to the bottom right but their position will change with the negative coming before the positive.
Also, the electric current arrow inside the circle points in the north west direction but when it is reversed, it will point in the north east direction.
Also, the winded coil over the pole remains the same.
Thus, the only option that fulfills this reversed positions is the 3rd electromagnet

What is mental health?Mental health affects cognition, perception, and behavior and includes emotional, psychological, and social well-being. It also affects how someone responds to stress, interacts with others, and makes decisions.
Subjective well-being, perceived self-efficacy, autonomy, competence, generational reliance, and self-actualization of one's intellectual and emotional potential are only a few examples of what is considered to be mental health.
The ability to enjoy life and strike a balance between daily activities and endeavors to develop psychological resilience may be considered a sign of mental health from the viewpoints of positive psychology or holistic approaches.

A 95 kg falling trunk strikes the ground with a speed of 40 m/s. Assuming that there is no loss of energy due to air resistance, what is the height from which the trunk falls?
Answer:
80 m or 81.3 m
Explanation:
Initially it had no velocity(as at rest). Let the height be h
Using conservation of energy:
Initial KE + PE = final KE + PE
(1/2) m(0)² + mgh = (1/2) m(40)² + mg(0)
mgh = (1/2) m (1600)
2gh = 16000
h = 1600/(2*10) {for g = 10}
h = 80
80 For g = 9.8, h = 81.3 m
Using Newton's eqⁿ of motion:
v² = u² + 2aS
40² = 0² + 2(g)S
1600/2g = S
For g = 10, S = 80 m
g = 9.8, S = 81.33 m

The first law states that an object either remains at rest or continues to move at a constant velocity, unless it is acted upon by an external force.
Hope this helps!
Answer:
This
Explanation:
First Law: Newtons first law of motion explains what happens in a car crash because it basically states that the passenger will continue to travel at the same velocity until an unbalanced force acts on he or she. The force that will act upon he or she would be the window, so you should always wear a seat belt!
Second Law: In other words, it states that the force that is applied in the crash is proportional to mass of impacting cars. This means that the bigger the force of impacting cars, the bigger the force applied, which implies a greater destruction.
Third law: Newton's Laws Applied to Collisions. Newton's third law of motion is naturally applied to collisions between two objects. In a collision between two objects, both objects experience forces that are equal in magnitude and opposite in direction.

find the torque when the work done to more through an angel of 1/4π radians is 3j
Answer:
The torque is approximately 3.82 N·m
Explanation:
The relationship between work done, 'W', and the applied torque, 'τ' can be presented as follows;
W = τ × Δθ
Where;
W = The work done by the torque
τ = The magnitude of the torque
Δθ = The angle through which the object is turned
The parameters for 'W' and 'Δθ' are;
W = 3j
Δθ = 1/4 × π
From W = τ × Δθ, we have;
τ = W/Δθ
∴ τ = 3j/(1/4 × π) ≈ 3.81971863421 N·m
The torque, τ ≈ 3.82 N·m
A boy throws a ball vertically up. It returns to the
ground after 5 seconds. Find
(a) the maximum height reached by the ball.
(b) the velocity with which the ball is thrown up.
Answer:
31.25 m
25m/sec
Explanation:
Given :-
Time = 5sec
V = 0 (in going up)
U = 0 (in comming down)
Find :-
H and U by which it is thrown up
Since the total time is 5 sec ,therefore half time will be taken to go up and another half will be taken to go down .
We know that ,
V = U + gt
0 = U - 10*2.5
U = 25 m/sec
Also,
V² = U² +2gs
0 = 625 - 20s
s = 625/20 = 31.25 m

A softball player is running at 4.88 m/sec when she slides into second base coming to a stop in .872 seconds. How far did she slide, and what was her acceleration?
Answer:
d=v1t - .5at^2
d=4.88 x .872 - 0.5 x (4.88/0.872) x 0.872^2
d=4.255 - 2.12
d= 2.135m
Explanation:
acceleration is negative because she is slowing down.
