Energy conservation :
<span>kinetic energy Ek = braking work W </span>
<span>mV^2 = 2Fb*x </span>
<span>x = mV^2/2Fb = 1000*16.7^2/16.000 = 17.43 meters</span>
Hi Andrescruz9386
The ball in someone's hand is a balanced force because the object is staying in motion and is not changing at all so its evenly balanced, if its swinging back and fourth it is in motion and it wont stop till it becomes unbalanced, if the ball is just being held above the ground yes its balanced because nothing Is happening to it, its basically like a balance scale, if both sides are even and equal, than nothing will happen because there is no side that has more or less its equal so that's why its balanced, in order for it to be unbalanced it has to be brought upon unbalanced forces.
Answer:
i dont know what you mean
Explanation:
(a) Force between the two charges
The electrostatic force between the two charges is given by:
where k is the Coulomb's constant, q1 and q2 the two charges, r their separation.
In this problem:
Substituting into the equation, we find
(b) direction of particle q2
Particle q2 wants to move in the direction of the force acting on it. The direction of the force depends on the relative sign of the two charges: like charges attract each other, opposite charges repel each other. In this case, the two charges are both positive, so they repel each other and q2 tends to move away from particle q1.
Answer: False.
Explanation: The Earth rotates once per day in direction from East to West. The rotation of the Earth daily is responsible for day and night experienced, the areas of the Earth facing the Sun experiences day time while the areas of the Earth away from the Sun in the Earth's shadow experiences night time.
While the revolution of the Earth around the gives rise to a year, as it takes 365 days for the Earth to go round the sun.
