An elevator accelerates upward at 2.0 m/s?,
amm1812

Answer:

Force the floor exerts on the  passenger is 833 N.

Explanation:

  • Weight of passenger (F_{g}) = mg = 85 × 9.8 N = 833 N
  • Force the floor exerts on the  passenger (F_{N}) = ?
  • For the elevator with the speed as 2.0 m/s the net force is zero, it means that the force is balanced.

                                       i.e. F_{N} = - F_{g} = -mg = 833 N

                                       hence  F_{N} is 833 N

  • If the lift was not at a constant speed i.e. if it had acceleration (m/s^{2})  then the case would be different.

Suppose that a sound has initial intensity β1 measured in decibels. This sound now increases in intensity by a factor f. What is
topjm [15]

Answer:

β2= β1+10*f

Explanation:

comparing β2 and β1, it is said that β2 is increased by a factor of f.

for each factor of f, there is a 10*f dB increase.

therefore if the β1 is increases by an intensity of factor f

the new intensity would be β1+ 10*f
