The kinetic energy of an object is given by:
Kinetic energy = 1/2 * mass * velocity²
If the kinetic energy of the pendulum at the top of its swing is 0, then this tells us that the velocity of the pendulum at that point is 0. All of the kinetic energy is converted to potential energy, and the pendulum starts moving in the opposite direction after this point in time.
Answer:
The crusades created standardized methods of taxation and increased European trade.
Answer:
Large molecules such as hormones
Explanation:
The other options either have channels within the membrane to move through (water has aquaporins, ions like potassium have their own channels) or can diffuse directly through the membrane (CO2). Protein hormones cannot move through the plasma membrane, nor can they diffuse through it. Hope this helps!
Answer:
C. interact frequently with the audience.
Explanation:
Presentation can be defined as an act of talking or speaking formally to an audience in order to explain an idea, piece of work, project, and product with the aid of multimedia resources or samples.
Students who want to create an effective presentation should interact frequently with the audience.
This ultimately implies that, to create an effective presentation, speakers are saddled with the responsibility of interacting more often with the audience by taking questions, making a joke, getting them to repeat informations loud at intervals etc.
Additionally, students are advised to be passionate and show enthusiasm during their presentation because it would enhance their ability to speak confidently and as such leading to an engaging presentation.
