No, we can not add the magnitudes of those two forces.
<h3>What is Gravitational Force?</h3>
An attractive force between masses is a gravitational force. According to Isaac Newton's second law, F = ma, a gravitational force generates an acceleration just like all other forces do. Remember that according to Newton's second law, a body will accelerate if there is a net force acting on it in an inertial frame of reference (a coordinate system travelling at a constant speed). According to Newton's Universal Law of Gravitation, when two bodies, such as the Earth and the Sun, are in close proximity to one another, an attractive force naturally attracts them. This attraction results in an acceleration of the two objects.

Responder:
12374550,527 N / m²
Explicación:
Dado que:
Número de tacos = 10
Área de cada montante = 0.01 in²
Peso total de la persona = 180 libras
Usando la relación:
Presión = Fuerza / Área
La fuerza ejercida es el producto de la masa y la aceleración debido a la gravedad.
Masa = 180 libras = 81,47 kg
Aceleración por gravedad = 9,8 m / s²
Área total = (número de montantes * Área por montante) = (10 * 0.01) = 0.1 pulg²
Conversión a m²:
0,1 pulg² = 6,452 * 10 ^ -5 m²
Por lo tanto,
Presión = (81,47 * 9,8) / (6,452 * 10 ^ -5)
Presión = 798.406 / 0.00006452
Presión = 12374550.527 N / m²
Answer:
(a) Final speed of block = 3.2896 m/s
(b) 6.7350 m/s is the speed of the bullet-block center of mass?
Explanation:
Given that:
Mass of bullet (m₁) = 6.20 g
Initial Speed of bullet (u₁) = 929 m/s
Final speed of bullet (v₁) = 478 m/s
Mass of wooden block (m₂) = 850g
Initial speed of block initial (u₂) = 0 m/s
Final speed of block (v₂) = ?
<u>By the law of conservation of momentum as:</u>
<u>m₁×u₁ + m₂×u₂ = m₁×v₁ + m₂×v₂</u>
6.20×929 + 850×0 = 6.20×478 + 850×v₂
Solving for v₂, we get:
<u>v₂ = 3.2896 m/s</u>
Let the V be the speed of the bullet-block center of mass. So,
V = [m₁* u₁]/[m₁ + m₂] (p before collision = p after collision)
= [6.2 *929]/[5.2+850]
<u>V = 6.7350 m/s
</u>
Accept the flow of current and is measured in ohms
Liquids evaporate faster as they heat up and more particles have enough energy to break away. The particles need energy to overcome the attractions between them. ... Eventually even particles in the middle of the liquid form bubbles of gas in the liquid. At this point the liquid is boiling and turning to gas.
