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.
Answer:
magnification will be -0.025
Explanation:
We have given the radius of curvature = 12 cm
And object distance = 3 m
So focal length 
Now for mirror we know that
So 

v = 0.750 m
Now magnification of the mirror is 
Explanation:
radio waves, which include visible light waves.
Hello. You did not present the combinations the question refers to, which makes it impossible for this question to be answered accurately. However, I will try to help you in the best possible way.
To present the total force you must use the following formula: Mass x Acceleration.
To calculate the total mass, you must use the formula: Force / acceleration.
To calculate the acceleration you must use the formula: Force / mass.
<span>When air resistance acts, acceleration during a fall will be less than g because air resistance affects the motion of the falling objects by slowing it down. Air resistance depends on two important factors - the speed of the object and its surface area. Increasing the surface area of an object decreases its speed.</span>
