Answer:
Two marbles are launched at t = 0 in the experiment illustrated in the figure below. Marble 1 is launched horizontally with a speed of 4.20 m/s from a height h = 0.950 m. Marble 2 is launched from ground level with a speed of 5.94 m/s at an angle above the horizontal. (a) Where would the marbles collide in the absence of gravity? Give the x and y coordinates of the collision point. (b) Where do the marbles collide given that gravity produces a downward acceleration of g = 9.81 m/s2? Give the x and y coordinates.

<span>Gravity is an attractive force. All masses exert gravity, so matter pull toward each other. However, it is only significant when the masses are large, like that of Earth. Exactly what causes gravity still remains a mystery. Since all the other three fundamental forces (strong, weak, and electromagnetic) are caused by particles called bosons, some scientists think that gravity is caused by particles called the graviton. However, such a particle has not yet been observed, and its existence has not been proven yet.
Also, gravity does not hold EVERYTHING together, as another person has already mentioned. Static electricity holds your socks together after they come out of the dryer, not gravity. Also, gravity is too weak to hold together, say, the nucleus of atoms, or even atoms of molecules together.</span>

.40 as a fraction is 4/10 or 2/5
the 4 is in the tenths place, so put it over a 10 to make it a fraction.
then, simplify the fraction by dividing the numerator and denominator by 2, and you get 2/5
Answer:
1. Energía = 4 J
2. Fuerza = 1,3 N
3. Aceleración = 2 m/s²
4. Masa = 7,1 kg
Explanation:
Magnitudes físicas y sus unidades;
1. Energía = 4 Joules
Energía se puede definir como la habilidad (capacidad) para realizar un trabajo.
2. Fuerza = 1,3 Newton
Fuerza = masa * aceleración
3. Aceleración = 2 m/s²
Aceleración se puede definir como la tasa de cambio de la velocidad de un objeto con respecto al tiempo.
Esto simplemente significa que la aceleración viene dada por la resta de la velocidad inicial de la velocidad final a lo largo del tiempo.
4. Masa = 7,1 Kilograms
La masa se puede definir como una medida de la cantidad de materia de la que se compone un objeto o un cuerpo. La unidad de medida estándar de la masa de un objeto o un cuerpo son los kilogramos.
The calculated weight in newtons is 10 N.
Listed below is the data we will use:
Area A is where the pressure is P. Here are the details we were given:
A=1 cm2, P=101325 N/m, and w=?
Do the area conversion to square meters.
A=1cm2×1m2/1002cm2\s=1×10−4m2
From the definition of pressure, calculate the weight of the air column. In this instance, the air column's weight is determined by multiplying the atmospheric pressure by the air column's base area.
Fw = P atm A
= (101325N/m2) (1 10 4m2)
= 10N
The complete question is - Imagine a square column of the atmosphere, 1 cm on a side, that extends all the way to the top of the atmosphere. How much does this column of air weigh in newtons?
