Answer : The final temperature is, 
Explanation :
In this problem we assumed that heat given by the hot body is equal to the heat taken by the cold body.


where,
= specific heat of ice = 
= specific heat of water = 
= mass of ice = 50 g
= mass of water = 200 g
= final temperature = ?
= initial temperature of ice = 
= initial temperature of water = 
Now put all the given values in the above formula, we get:


Therefore, the final temperature is, 
Answer:
The electric and magnetic fields gradually increase.
Explanation:
Time constant in RL circuits, denoted by τ, is equal to the value of L / R which is the value of the inductor over the resistor. It is used to calculate the point when the current will reach the maximum value in the steady state of the circuit. Because of this behavior of the circuit, the magnetic field and the electric field gradually increase to their maximum values.
I hope this answer helps.
Answer:
hydrogen bond
Explanation:
Water has atom of oxygen and 2 atoms of hydrogen. The bond is formed between oxygen of one molecule and hydrogen of another molecule. This bond is called hydrogen bond.
Drinking water helps maintain nearly all processes of the human body and <em>homeostasis. </em>Further, drinking water helps,
- Digestion
- Absorption
- Circulation
- Saliva and mucus production
- Thermoregulation/homeostasis
- Lubrication of joints
- Boosts integumentary health.
- Helps in excretory systems
- Prevents dehydration of cells
- Reduces chance of hangover from alcoholic drinks.
- etc,
Succinctly, it is VERY important to drink water! Water is the source of human life and without water, we cannot survive.
My guess is A. I'm not 100% positive but i'm pretty sure.
