Answer:
Explanation:
the object will not move as the force exerted is not sufficient enough to overcome its force of friction
Answer:
Gravity is a force of attraction that exists between any two masses, any two bodies, any two particles. Gravity is not just the attraction between objects and the Earth. It is an attraction that exists between all objects, everywhere in the universe.
Explanation:
Answer:
No
Explanation:
Electric potential is the work done to bring a unit of charge (1 C) from infinity to a point inside an electric field.
Electric potential energy of a charge q is the energy required to keep it in an electric potential V. Electric potential energy is given by,
U = qV
Hence even if the two charges are on an equipotential surface (surface where the potential is the same at all points), the potenial energy will be different if the magnitude or nature of the charges are different.
<u>Answer</u>
224 Km
4 Km
<u>Explanation</u>
<u>Part 1</u>
The plane flies 100 Km north and then 200 Km east. This makes a 90° turn. To get the distance taken by the plane we get the hypotenuse.
c² = a² + b²
c² = 100² + 200²
= 50,000
c = √50,000
= 223.606 Km
The answer to the nearest whole number is 224 Km
<u>Part 2</u>
If the runner run 15 Km north then 11 Km south, the resultant distance would be,
15 - 11 = 4 Km
