Geologists use tools other than the law of superposition to help them with relative dating. Which statements describe those tools? Check all that apply.
Answers
Answer: Cross-cutting features are always younger than the surrounding rock.
When material erodes before sediment is deposited on it, a geologic gap results.
Explanation:
The options include:
1. An unconformity is created when lava pours out on Earth’s surface.
2. Faults are the result of volcanic activity.
3. Intrusions and extrusions are sedimentary formations.
4. Cross-cutting features are always younger than the surrounding rock.
5. When material erodes before sediment is deposited on it, a geologic gap results.
The law of superposition simply states that when there is a layers of rocks, we would see that the younger layers will lie and be on top of the layers that are older.
Other tools that can help scientist with relative dating are:
• Cross-cutting features are always younger than the surrounding rock.
• When material erodes before sediment is deposited on it, a geologic gap results.

Two magnets are held apart. Once released, the South Pole of one magnet moves toward the North Pole of another magnet until the magnets collide. How does the graph reflect the changes in energy that occur?
Answers
Answer:
Kinetic energy and velocity are at zero when the magnets are held apart, and both increase rapidly when they are released and move together. Energy stored in the magnetic field decreases.
Explanation:
easy
The increase in the kinetic energy occurs when both magnets are released.
Change in energy occurs between two magnets
The kinetic energy and velocity are at zero when the magnets are held apart from one another at a certain distance but the kinetic energy increases when they are released and move together so we can conclude that the increase in the kinetic energy occurs when both magnets are released.

¿Qué trabajo realiza una carreta que contiene una de masa 800 lb de cemento si se desplaza 100 m por un suelo nivelado?
Answers
Answer:
Ver respuesta en el procedimiento
Explanation:
En este caso, necesitamos la expresión que nos permite hallar el Trabajo realizado por un objeto a través de una distancia dada. Esa expresión es:
W = F * x (1)
Donde:
W: Trabajo en Joules (J)
F: Fuerza en Newton (N)
x: Distancia o radio en metros (m)
En este caso, solo tenemos una masa de 800 lb, y la distancia que se esta recorriendo. No tenemos ningún dato adicional que nos diga si por ejemplo, es empujado por una persona o parecido, solo los datos de la masa que lleva la carreta. Por lo tanto, la única fuerza que podemos asumir se está ejerciendo, sería la fuerza del peso del objeto que se calcula así:
P = mg (2)
Donde:
g: aceleración de gravedad (9,8 m/s²)
Ahora bien si reemplazamos (2) en (1) nos queda:
W = mgx (3)
Y antes de realizar el cálculo debemos convertir la unidad de masa en libra a kilogramo, usando la siguiente conversión: 1 lb -----> 0,454 kg por tanto:
m = 800 * 0,454 = 363.2 kg
Ahora podemos usar (3) y calcular el trabajo:
W = 363,2 * 9,8 * 100
W = 355936 J o simplemente 355,936 kJ
Espero te sirva.
PD: También puedes usar el valor de gravedad como 10 m/s² y tendrás un resultado de 363200 J o 363,2 kJ.

why would a bouncing ball eventually stop bouncing?
Answers
1. Friction
2. Gravity
3. Decrease in potential energy
The force of gravity pulls it down, and as the ball falls, its potential energy is converted to kinetic energy. When you drop the ball from a certain height, the potential difference is at its extreme point. When the ball hits the ground, the potential energy naturally decreases, which stops the ball from bouncing after a while.

Answer:
A ball when from moving to stoping
Explanation:
Kinetic = energy of motion
Potential = energy stored
When you roll a ball on the ground, it gains kinetic energy, but then the ball starts to slow down until it stops and it remains at rest which means it's at potential energy. It went from moving (kinetic) to stoping (potential)

3. A 6 kg block moving to the right at 4 m/s collides with and sticks to a stationary block of unknown mass. If the two blocks move off to the right at 3 m/s, what was the mass of the stationary block?
Answers
Answer: 2kg
Explanation:
This problem is a textbook conservation of momentum problem. The intial momentum is equal to the final momentum. For the initial state of each block, only the first one was moving. Then they both combine to move together.
Pi = Pf
with p = mv
(6kg)*(4m/s) = (6kg+xkg)(3m/s)
Let x equal the unknown mass of block 2
24 = 18 + 3x
6 = 3x
x = 2kg

Two charges separated by one meter exert a 9 N force on each other. If the charges are pushed to a 3 meter separation, the force on each charge will be 3 N.
True or False?
Answers
Answer:
False
Explanation:
The formula of force that exists between two charges is expressed as;
F = kq1q2/r²
If two charges separated by one meter exert a 9 N force on each other, the;
9 = kq1q2/1²
9 = kq1q2 ..... 1
If the charges are pushed to a 3 meter separation, then;
F = kq1q2/3²
F = kq1q2/9 .... 2
Divide both equations;
9/F = (kq1q2)/ kq1q2/9
9/F = kq1q2 * 9/ kq1q2
9/F = 9
F = 9/9
F = 1N
Hence if the charges are pushed to a 3 meter separation, then the force on EACH charge will be 1N. Hence the answer is False

A driver pushes on a car with a force of 8000 N for 15 seconds but is unable to move it. How much work is done
Answers
Answer:
the work done is zero.
Explanation:
Given;
applied force, F = 8000 N
time of force application, t = 15 s
Work done is given as the product of force and displacement. Since the car is unable to move, then the displacement is zero and the work done is zero.
Work done = Force x displacement
Work done = 8000 N x 0
Work done = 0
Therefore, the work done is zero.

A motorist is driving at a constant velocity of 28.0 m/s when he decides to pass a car is in front of him. He accelerates at a rate 2.50 m/s2 for 3.00 seconds while passing the car. What is his velocity at the end of the 3.00 seconds?
Answers
Answer:
Final velocity, V = 35.5m/s
Explanation:
Given the following data;
Initial velocity = 28m/s
Acceleration = 2.5m/s²
Time = 3 seconds
To find the final velocity, we would use the first equation of motion
V = U + at
Where;
V is the final velocity measured in m/s.
U is the initial velocity measured in m/s.
a is the acceleration measured in m/s².
t is the time measured in seconds.
Substituting into the equation, we have;
V = 28 + 2.5*3
V = 28 + 7.5
Final velocity, V = 35.5m/s
