Answer:
Explanation:
As warm air comes in contact with the glass, the air becomes cooler. When that happens the cool air can't hold as much water vapor which condenses on the glass.
The answer is C.
Answer: What is the acceleration of an object that moves at constant velocity? Acceleration is Zero
What is the net force on the object in this case? The ner force is also Zero
Explanation: If the velocity is constant means that the acceleration is zero, from Newton second law is clear that net force is also zero
Fnet= m* a as v is constant a=0 this Fnet is zero.
The answer is true a convex lens can produce a real image but not a viral image
Answer:
See the explanation below
Explanation:
In the attached image we can see the free body diagram and forces acting on the book.
Force F, which acts to the right, the friction force which acts in the opposite direction to the movement, i.e. to the left.
The force exerted by the weight of the book that is equal to the product of the mass of the book by the gravity of the book. The normal force that is equal in magnitude to the weight of the book but in the opposite direction.
