Aperson stands on a scale in an elevator. the maximum and minimum scale readings are 814.7 n and 321.8 n, respectively. the acceleration of gravity is 9.8 m/s 2 . assume the magnitude of the acceleration is the same during starting and stopping, and determine the weight of the person. answer in units of n.

the weight of the person is 57.98kg

Explanation:

According to Newton's second law:

The scale reads the normal force, so if the elevator is going upward:

and if it is going downward:

so:

because the value of the acceleration is equal in magnitude we can substitute one equation into the other.

b) returns freshwater to the earth.

c) returns freshwater to the earth.c) occurs after condensation.

d) returns freshwater to the earth.c) occurs after condensation.d) roughly equal to the amount of evaporation.

pls mark as brainliest.

so easy. just google the electromagnetic waves and it’ll pop up.
