The drawing represents a mountain bike trail. A rider began at Point 1 on the trail and stopped at Point 3. At which point did he have the least potential energy?
Answer:
Point 2.
Explanation:
Potential energy is simply defined as the energy stored in an object due to its position. It is can be represented mathematically by:
P.E = mgh
Where:
P.E is the potential energy.
m is the mass of the object.
g is acceleration due to gravity.
h is the height to which the object is located.
From the above equation, we can thus say that potential energy depends on the height of the object since the mass of the object is always constant i.e as the height of the object increase, the potential energy also increases and as the height of the object decrease, the potential energy also decreases.
Now, considering the diagram in the question given, we can see that point 2 is the lowest height to which the rider is located. At this point i.e point 2, the rider will have the least potential energy.
Answer: Point 2

Object A has a mass of 10 kg and is moving at a velocity of 2.0
m/s. So Object A's momentum is - kg. m/s.
Answer:20kgm/s
Explanation:
Mass=10kg
Velocity=2m/s
Momentum=mass x velocity
Momentum=10 x 2
Momentum=20
Momentum=20kgm/s
The object with mass m when moving with the velocity, its momentum can be calculated. The momentum of the object A is 20 kg.m/s.
What is momentum?Momentum is the product of mass and velocity of a moving object.
If the momentum is p, the mass of the object is 10 kg and the velocity is 2.0 m/s, then the momentum will be
p = 10 × 2.0
p = 20 kg.m/s
Thus, the momentum of the object A is 20 kg.m/s

over years of being underground the pressure causes the organism to press into the rock and form a mold. this mold is the fossil and are found in sedimentary rock
You have a large flashlight that takes 4 D-cell batteries, each with a voltage of 1.5 volts. If the current in the flashlight is 2.0 amps, what is the
resistance?
A 12 ohms
B 0.75 ohms
C 3.0 ohms
D.0.5 ohms
E. 6.0 ohms
Answer:
The answer is "C. 3.0 ohms".
Explanation:
Ohm's law states the following:,
V = IR
where:
Voltage (V) = 1.5 volts × 4 batteries = 6.0 volts
Current (I) = 2.0 amps
Resistance (R) = ? ohms
To solve for Resistance (R) the equation must be rearranged this way:
R = V / I
Then, the variables must be replaced with the known values:
R = 6.0 volts / 2.0 amp
R = 3.0 ohms
The answer is C. 3.0 ohms.

What are energy and work
Answer:
In physics, energy is the quantitative property that must be transferred to an object in order to perform work on, or to heat, the object. Energy is a conserved quantity; the law of conservation of energy states that energy can be converted in form, but not created or destroyed.

Indicate what a specific property of matter is. Also explain why the specific properties of matter are useful compared to the general ones.
Solution
The specific properties of matter are properties that describes the intensive properties of the system. They are properties that do not depend on or change with the extent or size of the system. They are usually obtained by dividing the generalised properties or extensive properties by the extent or size of matter to make them independent of size/extent/Mass.
Examples of specific properties include specific heat capacity, specific volume etc. They usually have units of general units/Mass units.
The specific properties of matter are more important than the general ones because
- They help in general comparisons of the properties of different materials. They are used to rank, classify and compare properties of different materials.
- They are used in reference table/data to easily record easily accessible properties of matter. It helps to record standards that are general and independent of sizes/extents/Mass, thereby keeping the reference table/data/chart precise and concise.
- They provide us with values that are easy to memorize and remember, unlike trying to cram the different properties of different masses/sizes of matter.
In Spanish/En español
Las propiedades específicas de la materia son propiedades que describen las propiedades intensivas del sistema. Son propiedades que no dependen ni cambian con la extensión o el tamaño del sistema. Por lo general, se obtienen dividiendo las propiedades generalizadas o las propiedades extensivas por la extensión o el tamaño de la materia para hacerlas independientes del tamaño / extensión / masa.
Los ejemplos de propiedades específicas incluyen capacidad calorífica específica, volumen específico, etc. Usualmente tienen unidades de unidades generales / unidades de masa.
Las propiedades específicas de la materia son más importantes que las generales porque
- Ayudan en las comparaciones generales de las propiedades de diferentes materiales. Se utilizan para clasificar, clasificar y comparar propiedades de diferentes materiales.
- Se utilizan en la tabla / datos de referencia para registrar fácilmente propiedades de materia fácilmente accesibles. Ayuda a registrar estándares que son generales e independientes de tamaños / extensiones / masa, manteniendo así la tabla / datos / tabla de referencia precisa y concisa.
- Nos proporcionan valores que son fáciles de memorizar y recordar, a diferencia de tratar de agrupar las diferentes propiedades de diferentes masas / tamaños de materia.

Calculate the first and second velocities of the car with four washers attached to the pulley, using the formulas
v1 = 0.25 m / t1 , and v2 = 0.25 m / (t2 – t1)
where t1 and t2 are the average times the car took to reach the 0.25 and the 0.50 meter marks. Record these velocities, to two decimal places, in Table E
The first and second velocities of the car, with four washers attached to the pulley, are both 0.125 m/s.
We must apply the following calculations to determine the car's first and second velocities with the four washers attached to the pulley:
v1 = 0.25 m / t1
v2 = 0.25 m / (t2 - t1)
Here, t1 denotes the typical time needed for the car to go 0.25 metres, and t2 is the typical time needed to travel 0.50 metres.Let's say that t1 and t2 are the typical times, each lasting two seconds on average.The first formula allows us to determine v1:
v1 = 0.25 m / 2 s = 0.125 m/s
Using the second formula, we can calculate v2:
v2 = 0.25 m / (4 s - 2 s) = 0.125 m/s
Table E can be used to record these values as the velocities at the relevant distances.
