Water vapor clouds that are breaking out of Europe’s surface, water is the basis of life so this would support the idea that there is life
The answer is current.
Current in the context of an electrical circuit is the flow of charge. Current is a quantity that is physical and can be measured. Current is defined as the rate of the flow charge past a certain point in a circuit. Current is expressed in Amperes which is equal to 1 coulomb/1second.
Answer:
b) there must be a component of force parallel to the motion of the object.
Explanation:
We know that work done on a body by an external force is calculated by the formula given below:
W = F.d = Fd Cos θ
where,
W = Work Done by the force on the body
F = Magnitude of force
d = displacement of the body
θ = The angle between the direction of motion of the body and the force applied
It is clear from the formula of the work done, that "F Cosθ" represents the component of the force, that is acting in the direction of motion of the object or parallel to the direction of motion of the object. So, if there is no component of force parallel to motion of object, then this factor will become zero. As a result, the work done will also be zero.
Therefore, the correct option will be:
b) <u>there must be a component of force parallel to the motion of object.</u>
<h2>
Mass of object in Earth is 1.37 kg</h2>
Explanation:
On planet B where the magnitude of the free-fall acceleration is 1.91g , the object weighs 25.74 N.
We have
Weight = Mass x Acceleration due to gravity
On planet B
25.74 = Mass x 1.91 g
25.74 = Mass x 1.91 x 9.81
Mass = 1.37 kg
Mass is constant for an object. It will not change with location.
Mass of object in Earth = Mass of object in Planet B
Mass of object in Earth = 1.37 kg
Answer:
Distancia = 60 metros
Explanation:
Dados los siguientes datos;
Velocidad inicial = 0 m/s (ya que comienza desde el reposo)
Velocidad final = 12 m/s
Por lo tanto, velocidad total = velocidad inicial + velocidad final
Velocidad total = 0 + 12 = 12 m/s
Tiempo = 5 segundos
Para encontrar la distancia recorrida;
Distancia = velocidad total * tiempo
Sustituyendo en la fórmula, tenemos;
Distancia = 12 * 5
Distancia = 60 metros
