Answer:
The particle will continue moving at constant velocity
Explanation:
When the particle encounters the second force of 10 N, the net force acting on the particle becomes zero, because the two forces are equal in magnitude but opposite in direction:
For Newton's second Law, the acceleration of the particle is proportional to the net force acting on it:
Therefore, since , the acceleration is zero (a=0) and so the particle will keep a constant velocity.
Answer:
Gravitational force is directly proportional to the distance between objects.
Answer:
E = 1000 x
Explanation:
The electric potential and the electric field are related by the formula
dV = - E . dx
Bold represents vectors.
The point represents the scalar product, in this case we calculate the electric field in the x-axis and the potential is also in this axis so the scalar product is reduced to the algebraic product
E = dV /dx
Let's make the derivative
E = - 2ax
Let's replace the values
E = -2 (-500) x
E = 1000 x
Answer:
a bicycle has more kinetic energy cuz kinetic energy depends on mass and velocity.bicycle has more mass than a tennis ball.
