英国曼彻斯特大学Essay代写:电能定义和实例

电能是由电荷流动产生的一种能量形式。能量是指工作或用力移动物体的能力。在电能的情况下,力是带电粒子之间的电吸引或排斥。电能可以是势能或动能,但它通常作为势能遇到,其是由于带电粒子或电场的相对位置而存储的能量。带电粒子通过导线或其他介质的运动称为电流或电流。还存在静电,其由物体上的正电荷和负电荷的不平衡或分离引起。静电是一种电势能。如果积聚足够的电荷,则可以释放电能以形成具有电动能的火花(或甚至闪电)。按照惯例,电场的方向始终显示为指向正粒子放置在场中时将移动的方向。在处理电能时,这一点很重要,因为最常见的电流载流子是电子,与质子相比,它在相反的方向上移动。 英国曼彻斯特大学Essay代写:电能定义和实例 Electrical energy is a form of energy resulting from the flow of electric charge. Energy is the ability to do work or apply force to move an object. In the case of electrical energy, the force is electrical attraction or repulsion between charged particles. Electrical energy may be either potential energy or kinetic energy, but it's usually encountered as potential energy, which is energy stored due to the relative positions of charged particles or electric fields. The movement of charged particles through a wire or other medium is called current or electricity. There is also static electricity, which results from an imbalance or separation of the positive and negative charges on an object. Static electricity is a form of electrical potential energy. If sufficient charge builds up, the electrical energy may be discharged to form a spark (or even lightning), which has electrical kinetic energy. By convention, the direction of an electric field is always shown pointing in the direction...

英国曼彻斯特大学Essay代写:Simone de Beauvoir

西蒙娜·德·波伏娃于1967年发表了她的短篇小说“女人被毁”。与许多存在主义文学一样,它是以第一人称写成的,故事由莫妮克撰写的一系列日记条目组成,莫妮克是一位中年妇女,她的丈夫是一个勤奋的医生,他的两个长大的女儿不再住在家里。在故事的开头,她刚刚看到她的丈夫去了罗马,他在那里开了一个会议。她计划悠闲地开车回家,享受随意做任何她想做的事情,不受家庭义务的限制。 “我想为自己生活一点点,”她说,经过这么久。“然而,当她听到帽子Colette时,她的一个女儿患了流感,她缩短了她的假期,所以她可以在她的床边这是第一个迹象表明,在花了这么多年致力于其他人后,她会发现她新发现的自由很难享受。回到家里,她发现她的公寓非常空虚,而不是享受她的自由,她只是感到孤独。一天或者所以后来她发现她的丈夫莫里斯一直与诺埃莉有染,这是一个和他一起工作的女人。她很沮丧。 英国曼彻斯特大学Essay代写:Simone de Beauvoir Simone de Beauvoir published her short story, "The Woman Destroyed," in 1967. Like much existentialist literature, it is written in the first person, the story consisting of a series of diary entries written by Monique, a middle-aged woman whose husband is a hard-working doctor and whose two grown up daughters no longer live at home. At the beginning of the story she has just seen her husband off on a flight to Rome where he has a conference. She plans a leisurely drive home and relishes the prospect of being free to do whatever she wants, unconstrained by any family obligations. "I want to live for myself a little," she says, after all this time." However, as soon as she hears hat Colette, one of her daughters has the flu, she cuts her vacation short so she can be by her bedside. This is the first indication that after spending so many years devoted to others she...
