what is the mass of modelling clay?
the mass of modelling clay is 500g
A student claims that gravitational fields exist between objects that are not in contact with each other. She creates a diagram of two figures. The width of the arrows in Figure A and Figure B represent the strength of the gravitational attraction between two objects.
The student claims the gravitational force is greater between the objects in Figure A. Which argument best supports her claim?
A. The masses of the objects in Figure A are less than the masses of the objects in Figure B.
B. The distance between the objects in Figure A is shorter than the distance between the objects in Figure B.
C. The surface area of the larger object in Figure A is greater than the surface area of the larger object in Figure B.
D. The diameters of the objects in Figure A are greater than the diameters of the objects in Figure B.
Answer:
Option B. The distance between the objects in Figure A is shorter than the distance between the objects in Figure B.
Explanation:
The force of attraction between two masses is given by the following equation:
F = GM₁M₂ / r²
Where:
F => is the force of attraction
M₁ and M₂ => are the masses of the two objects
G => is the gravitational constant.
r => is the distance between the two objects
From the above formula,
The force of attraction (F) is directly proportional to the product of the two masses and inversely proportional to the square of their apart.
This implies that:
1. An increase in the masses of the object will bring about an increase in the force of attraction and a decrease in the masses will leads to a decrease in the force of attraction.
2. An increase in the distance between the two masses will leads to a decrease in the force of attraction and a decrease in the distance between the two masses will lead to an increase in the force of attraction.
Considering the options given in the question above, option B gives the correct answer to the question.

what is the formula for calculating the magnitude of kinetic frictional force
This means that measuring the pulling froce F is like measuring the force of static friction fs . Uk = FK . here
f= FK. FK = force of kinetic friction uk = coefficient of kinetic friction and N= normal to the contacting surfaces.
Define 1 pascal pressure
Answer:
Hey mate....
Explanation:
This is ur answer.....
A pascal is a pressure of one newton per square metre, or, in SI base units, one kilogram per metre per second squared. For example, standard atmospheric pressure (or 1 atm) is defined as 101.325 kPa. The millibar, a unit of air pressure often used in meteorology, is equal to 100 Pa.
Hope it helps you,

pascal is the SI unit of pressure symbolized by Pa
1 Pa=1N/m^2
1Pa=1kg/ms^2
Where is the most and the least KENETIC ENERGY
Answer:
Where is kinetic energy the least?, and most?
Explanation:
Least : When the Moon is farthest from Earth in its nearly elliptical orbit, its speed is least. Its kinetic energy has become least, and its potential energy is greatest.
Further : Kinetic energy, form of energy that an object or a particle has by reason of its motion. If work, which transfers energy, is done on an object by applying a net force, the object speeds up and thereby gains kinetic energy.

2.Write the formula associating energy with power
3.Write the formula associating potential energy with height.
(PLEASE HELP ASAP )
Explanation:
2. Power is defined as the rate of doing work. Mathematically, it can be given by :
[tex]P=\dfrac{W}{t}[/tex]
Where
W is work done or energy
t is the time taken
3. The formula of potential energy can be given by :
[tex]P=mgh[/tex]
Where
m is the mass of the object
g is the acceleration due to gravity
h is height
Hence, this is the required solution.

Un tren de alta velocidad (TAV) o tren bala es aquel que alcanza velocidades iguales o superiores a 200 km/h. La energía que tiene el tren en su recorrido habitual es: *
Answer:
B. Cinética, debido a que esta energía está asociada con la velocidad que posee el tren.
Explanation:
Un tren de alta velocidad (TAV) o tren bala es aquel que alcanza velocidades iguales o superiores a 200 km/h. La energía que tiene el tren en su recorrido habitual es
A. Cinética, debido a que existen trenes elevados los cuales poseen altura y la altura está asociada con la energía cinética.
B. Cinética, debido a que esta energía está asociada con la velocidad que posee el tren.
C. Rápida, porque la energía cinética es sinónimo de rápido.
D. Potencial, debido a la potencia que tiene el tren para moverse.
Solution:
La energía cinética es la energía contenida en un objeto en movimiento. La energía cinética se puede definir como la cantidad de energía necesaria para que un objeto se acelere desde el reposo hasta su velocidad final.
La energía cinética (KE) viene dada por:
KE = (1/2) * masa * velocidad²
Podemos ver que la energía cinética depende de la masa del objeto y la velocidad del objeto.
El tren de alta velocidad posee energía cinética debido a la velocidad del tren.

Wat would happen if a feather and a ball were released from the same height at the same time? Gravity Experiments for Kids – Science Experiments for Kids
Answer:
They would land at the same time
Explanation:
They would land at the same exact time.
As weird, impossible and unbelievable as it appears. When in a vacuum, every weight, body and material when released from the same height would land on the ground at the same time. This also means that like in the question, a feather and a ball would land at the same time. And just for illustrations as well, a feather and a car would land at the same time as well.
Una bola se lanza verticlamente de la parte superior de un edificio con una velocidad inicial 25 m/s la bola impacta al suelo en la base del edificio 7 segundos despues de ser lanzada ¿que altura subio la bola
Answer:
S = 415.1 meters
Explanation:
Dados los siguientes datos;
Velocidad inicial = 25 m/s
Tiempo, t = 7 segundos
Para encontrar la altura (desplazamiento) de la pelota, usaríamos la segunda ecuación de movimiento;
[tex] S = ut + \frac {1}{2}at^{2}[/tex]
Dónde;
S representa el desplazamiento o altura medida en metros.
u representa la velocidad inicial medida en metros por segundo.
t representa el tiempo medido en segundos.
a representa la aceleración medida en metros por segundo cuadrado.
Sustituyendo en la ecuación, tenemos;
[tex] S = 25*7 + \frac {1}{2}*(9.8)*7^{2}[/tex]
[tex] S = 175 + 4.9*49 [/tex]
[tex] S = 175 + 240.1 [/tex]
S = 415.1 meters

How much power is needed to lift a 20-kg object to a height of 4.0 m in 2.5 seconds?
Answer:
313.92w
Explanation:
Formula for power:
P=W/∆t = Fv
Givens:
m=20kg
∆y=4.0m
∆t=2.5s
a=9.81m/s²
In order to find power, we first need to solve for work.
W=Fd (force*displacement), f=mg
W=mg∆y
W=(20kg)(9.81m/s²)(4.0m)
W=784.8J
P=W/∆t
P=784.8J/2.5s
P=313.92 watts

¿Qué función trigonométrica describe la manera como el voltaje y la corriente varían con el tiempo en un circuito CA?
Answer:
función sinusoidal
Explanation:
En un circuito de CA, la corriente y el voltaje tienen un voltaje máximo y mínimo. A intervalos regulares, la corriente y el voltaje invierten la dirección y cambian su magnitud continuamente con el tiempo.
Por lo tanto, para representar la corriente y el voltaje en un circuito de CA, se utiliza una función sinusoidal. Una función seno es una función continua con oscilaciones periódicas.
