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.

Answer:
679.08 lbs
Explanation:
Here it is given that
= Mass of first person = 175 pounds
= Height of first person = 70 inches
= Mass of second person
= Height of second person = 110 inches
The weight of the second person would be 679.08 lbs
Answer:
F = 268 Hz
Explanation:
The beat frequency is given as:
|
So, for the first flute and tuning fork:
where,
F = Frequency of tuning fork
F = 248 Hz ± 20 Hz
F = 268 Hz (OR) 228 Hz
Now, for the second flute and tuning fork:
where,
F = Frequency of tuning fork
F = 288 Hz ± 20 Hz
F = 268 Hz (OR) 308 Hz
Since, 268 Hz is common from both calculations. Therefore, it will be the frequency of the tuning fork.
<u>F = 268 Hz</u>
When a heavy football player and a light one run into each other, does the lighter player really exert as much force on the heavy player s the heavy player exerts on the light one. Yes. The interaction between the two players, the force each exerts on the other have equal strength.
