Answer:
Hmmm...It should be B.
Explanation:
You can't just assume you have depression just because of one day of sadness. You have to wait until you get more...factors or "symptoms", if so, you shouldn't diagnose yourself until you can confirm it by a mental health doctor (Not sure what it's called) or therapist.
××× If it's not B, I sincerely apologize! ×××
(This is just an example)
Answer:
54 kg
Explanation:
Mass of person = 93 kg =
Mass of water = 62 kg =
Dividing the above two masses we get
Hence, the mass of the person is 1.5 times the mass of the water in them
Now, Mass of person = 81 kg =
So, the mass of water in a person that has mass of 81 kg is 54 kg
Answer:
18.1 MN/C
Explanation:
The gravitational force of the plastic sphere is in equilibrium with the electric force.
Mass of the plastic sphere = m = 14.2 g = 0.0142 kg
Force of gravity = F = mg = (0.0142)(9.81) = 0.139 N
This force is balanced by the electric force due to the charge 7.7 nC
Charge = q = 7.7 x 10⁻⁹ C
Electric field = E = F / q = (0.139) /(7.7 x 10⁻⁹) = 18.1 MN/C
Answer:
The temperature raise is = 0.14 [C]
Explanation:
In order to find the temperature difference we must use the following equation:
But first we need to find the original volume V:
When the volume is increased the diameter will be larger:
D1 = 0.125[m] + 0.0002[m] = 0.1252[m]
Therefore the new radius will be:
r1=0.0626[m]
The new volume is:
Replacing all the calculated values in the equation:
Answer:
c
Explanation:
Increasing the length of string to which the bob is attached, increases the radius of the circle on which the bob moves; and therefore, the frequency, or number of back and forth swings in a set time frame, will be less.
