The amount of time between two given points in time; ex would be 3:00pm to 5:00pm is two hours
Answer: The correct answer is A.
Explanation:
In magnets, there are two poles: South and north poles. Like poles repel each other. Unlike poles attract each other.
When two magnets of the opposite poles are brought together then the poles are attract each other.
When two magnets of the same poles are brought together then the poles are repel each other.
Therefore, the correct answer is A.
A uniform speed is 0.45.
<u>Solution:</u>
F = mv^2/r
r = 0.2m
v = 0.75 m/s
m = 0.160 kg
F = 0.16*(0.75)^2/0.2 = 0.45.
If you spin a ball with a string or spin a lasso pulling on the rope will pull the object toward the center. Centripetal force is provided by the frictional force between the ground and the wheels as the car turns. A force acting on a moving object at an angle to the direction of motion that tends to cause the object to follow a circular or curved path.
The gravitational force acting on an orbiting satellite is an example of a centripetal force. The friction of a car's tires while cornering similarly exerts a centripetal force on the car. Satellites orbit around the earth due to the gravitational pull of the earth. Movement of electrons around the nucleus. Movement of the blades of the windmill. The tip of the second-hand watches with circular dials exhibits a smooth circular motion.
