Gina stands 1.5 m in front of a plane mirror. She is 160 cm tall (i. e. HF = 160 cm) and her
eyes (E) are 10.0 cm below the top of her head (H).
What is the shortest length of the vertical mirror that will enable her to see her entire
image? Draw a ray diagram below with necessary calculation below to support your answer.
Please help!

Act has a 1200: 5 or 240: 1 turns ratio. it is short circuited. what is the maximum current at 1200a primary if we put a 100ohm resistor across the secondary end of the ct. use it as current source circuit.

Aphysical change is a change in the size, shape,, or stafe of matter true or false

Three different objects, all with different masses, are initially at rest at the bottom of a set of steps. each step is of uniform height . the mass of each object is a multiple of the base mass : object 1 has mass 4..00m , object 2 has mass 1..96m , and object 3 has mass . when the objects are at the bottom of the steps, define the total gravitational potential energy of the three-object system to be zero. if the objects are then relocated as shown, what is the new total potential energy of the system? each answer requires the numerical coefficient to an algebraic expression. each algebraic expression is given using some combination of the variables , , and , where is the acceleration due to gravity. enter only the numerical coefficient. (example: if the answer is 1..23mgd , just enter 1.23)
