Which of these is the best explanation for why two negatively charged balloons, if put close, will repel?

1 answer:

6 0

I cannot see your options, but my best guess is that the same charges repel, and different charges attract. If one of the balloons was positively charged, they'd attract, but because both of them are negative, then they repel. If that's not an option then let me know and I can edit my answer :)

I hope this helps!

Net work done on student B by the Ferris wheel in moving from the top to the bottom is mathematically given as

net work done on A =0.

Generally the equation for the work energy theorem is mathematically given as

net work done on A = change in kinetic energy of A.

Where, angular velocity is constant.

change in kinetic energy = 0.

Hence, from work energy theorem,

net work done on A =0.

An 880 kg cannon at rest fires a 12.4 kg cannonball forward at 540 m/s. What is the recoil velocity of the cannon

Marina86 [1]

Answer:

<em>The recoil velocity of the cannon is 7.61 m/s in the opposite direction of the cannonball</em>

Explanation:

<u>Linear Momentum </u>

The principle of conservation of the linear momentum establishes that the sum of the linear momentums of every object in an isolated system (no external forces) is constant, regardless of the interactions between them.

Let's think we have two objects with masses $m_1$ and $m_2$ , moving at speeds $v_1$ and $v_2$ . If they collide and change their speeds to $v_1'$ and $v_2'$ , then

$m_1v_1+m_2v_2=m_1v_1'+m_2v_2'$

In our problem, the 880 kg cannon is initially at rest and has the cannonball of 12.4 Kg inside of it. As the initial speed of both joined objects is zero, the initial total momentum is zero. After the ball is fired, the ball moves at v_2=540 m/s. We need to find the recoil velocity of the cannon $v_1'$

$m_1v_1'+m_2v_2'=0$
