(1 point) Newton's law of cooling states that the temperature of an object changes at a rate proportional to the difference betw
een its temperature and that of its surroundings. Suppose that the temperature of a cup of coffee obeys Newton's law of cooling. If the coffee has a temperature of 195 degrees Fahrenheit when freshly poured, and 2 minutes later has cooled to 183 degrees in a room at 60 degrees, determine when the coffee reaches a temperature of 143 degrees. The coffee will reach a temperature of 143 degrees in

Answer:
When I got this question I had to draw it out so if you have to do that, draw 3 stick figures holding hands, one representing the mother, father, and daughter. Then you write their weights on top of them and then draw an arrow pointing from the father to the mother.
Explanation:
use this formula :
=
then you fill it in :
=
=
=
then you multiply that with the daughters weight :
and that's the answer :) : 37.89N
Answer:
Radius of the circle will be 2.5 m
Explanation:
We have given velocity of particle moving in the circle v = 5 m/sec
Acceleration of particle in the circle
We have to find the radius of the circle
We know that acceleration is given by
So
So radius of the circle will be 2.5 m
