Ms d arrived at school at 7: 30 am, she spent 35 minutes at the dinner with a friend it takes her 15 minutes to get to school what time did ms d left

Ms D left at 6:40 AM

Step-by-step explanation:

Given:

MS D arrived at school at 7:30 AM

time spent for dinner = 35 mins

Time taken to to go to school = 15 mins

We will first find the Total time taken after leaving.

Total time taken can be calculated by adding time spent for dinner and Time taken to to go to school.

Total time taken after leaving = time spent for dinner + Time taken to to go to school = 35 +15 = 50 mins

MS D arrived at school at 7:30 AM.

Hence Time Ms D left  = Time She arrive at school - Total time taken after leaving = 7 hrs 30 min - 50 mins = 6 hrs 40 mins.

Hence Ms D left at 6:40 AM.

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v
