Answer:
9.6 m/s
Explanation:
Equation is v=d/t so plug 120m to d (distance) and 12.5 sec to t (time).
v=120/12.5

Un bat de beisbol ejerce una fuerza promedio de 50n sobre una pelota durante 0.40s.¿ que impulso recibio la pelota tras ser bateada una pelota? De beisbol de 0.11 kg se separa de bat con una rapidez horizontal de 36m/s si el bat esta en contacto con la pelota or 0.5 s ¿cual es el valor de la fuerza horizontal promedio que ejerce el bat en la pelota?
Answer:
A) I = 20 N s
, B) F = 7.92 N
Explanation:
A) The momentum is
I = F Δt
calculate
I = 50 0.40
I = 20 N s
B) The momentum is related to the change of the moment of the system
I = Δp
F Δt = m [tex]v_{f}[/tex] - m v₀
in this case we must assume that the initial velocity is very small, vo = 0
F = m v_{f} / Δt
calculate
F = 0.11 36 / 0.5
F = 7.92 N
The number of particles inside the nucleus will always equal the....?
Explanation:
Scientists define these charges as “+1” and “−1.” In an uncharged, neutral atom, the number of electrons orbiting the nucleus is equal to the number of protons inside the nucleus. In these atoms, the positive and negative charges cancel each other out, leading to an atom with no net charge.
Which resultant force is NOT possible if 50 N force and a 60 N force act concurrently?
Answer:
The options are not shown, so i will answer in a general way.
Suppose the case where the forces act in opposite directions, then we need to subtract the forces, and we know that the magnitude of the resultant force will be:
60N - 50N = 10N
Now, suppose the case where both forces act in the exact same direction, in that case, we will add the forces to get:
60N + 50N = 110N
Then the only range of forces that we can get in this system, are the forces such:
10N ≤ F ≤ 110N
Any resultant force outside that range is not possible in this situation.

Explanation:
What would you need to do to find the number of neutrons in an atom?
Answer:
You subtract the atomic number from the atomic mass to find the number of neutrons alone
Explanation:
The atomic number is the number of protons OR electrons. They are both equal thus making the atom have a neutral charge. The relative atomic mass is the number of protons AND neutrons.

So I need you to write a hypothesis about finding and marking stars on "Worldwidetelescope", I dont know how to start a hypothesis and a paragraph about what I did in this project. I know what I did but someone have to help me with the hypothesis and how to start the paragraph and please make a list of everything it should include, Thank you!!
Answer:
I don't really know much about the whole stars thing, but I've written a lot of paragraphs in science
Explanation:
Remember:
A paragraph should be in CER formation: Claim (hypothesis/discovery), Evidence, and ReasoningYour reasoning should never start with I believe or I think, your reasoning and evidence are 100% fact basedThe actual hypothesis should only be 1-2 sentences and be straight to the pointInclude:
for your hypothesis, keywords relating to your subject, I'm assuming for your topic you should include things like marking, telescope, stars, etc.why you believe your hypothesis is true so use prior knowledge to justify your hypothesisDoes anyone know this or done it?

Explanation:
a rope is used to pull a 2.89kg bucket of water out of a deep well. what is the acceleration of the bucket when the tension in the rope is 30.2N?
Answer:
Explanation:
Tension in the rope in upward direction = 30.2 N .
weight of bucket in downward direction = mg
net force in upward direction = 30.2 - mg
30.2 - 2.89 x 9.8
= 1.878 N
acceleration = net force / mass
= 1.878 / 2.89
= .65 m /s² .
= 65 cm /s²
The acceleration of the bucket will be "65 cm/s²".
Tension and acceleration:Whenever the rope, thread, or cable is expanded underneath an applied force, a force is created in that as well, is a tension force.
Tension acts anywhere along the lengths of the string throughout the opposing directly proportional to the force acting upon that.
According to the question,
Tension in the rope = 30.2 N
Mass of bucket, m = 2.89 kg
Acceleration due to gravity, g = 9.8
Now,
The net force will be:
= Tension - mg
= [tex]30.2-(2.89\times 9.8)[/tex]
= [tex]1.878[/tex] N
hence,
The acceleration of the bucket be:
= [tex]\frac{Net \ force}{Mass}[/tex]
By substituting the values,
= [tex]\frac{1.878}{2.89}[/tex]
= [tex]0.65[/tex] m/s²
or,
= [tex]65[/tex] cm/s²
Thus the above approach is correct.

What is the approximate momentum of a car with a mass of 1200 kg and a velocity of 30 - km/hr(8.33 m/s) ?
Answer:
9996kg.m/s
Explanation:
∆p=mv. 1200kg*8.33m/s
The approximate momentum of this car is 9,996 Kgm/s.
Given the following data:
Mass = 1200 kg Velocity = 8.33 m/s
To determine the approximate momentum of this car;
Momentum refers to the product of the mass possessed by an object and its velocity.
Mathematically, momentum is giving by the formula;
[tex]Momentum = mass \times velocity[/tex]
Substituting into the formula, we have;
[tex]Momentum = 1200 \times 8.33[/tex]
Momentum = 9,996 Kgm/s.

Egypt is conducting an experiment on speed. She is measuring the speed of another middle schooler as she walks from science class to math class in her school. The graph below represents the speed of one of her friends as she walks the 20 meters over 5 minutes.
Speed Graph
Answer:
See the answer below
Explanation:
The two correct options are:
1. The student traveled the fastest between 4 and 5 minutes
2. The average speed of the student is 4 meters per minute
Between 4 and 5 minutes, the approximate distance of 7 meters covered by the student is the longest of all the distances covered per minute. Since speed is a measure of distance covered relative to time, it means that the student traveled the fastest between these periods.
The average speed is calculated by dividing the total distance traveled by a body by the total time taken to cover the distance.
From the graph:
Total distance covered = 20
Total time taken = 5
Average speed = 20/5 = 4 meters per minute
All the remaining conclusions are incorrect or indeterminate going by the information on the graph.
