Answer: The speed of the edge of the wheel = 19.72m/s
Explanation:
The liner speed of the edge of the wheel is given as;
V=wr
V= linear speed =?
w= angular velocity =456rpm
Converting rpm to rad/s
1rpm = π/30 rad/s
456rpm = 47.75 rad/s
r=0.413m
V=47.75 × 0.413
V= 19.72m/s
Therefore speed of the edge of the wheel = 19.72m/s
Answer:
(1) Support
(2) Tension
(3) Reaction
The constraint forces are forces that occur in pairs such that the net force (effect) is zero
The details of the constraint forces are;
(1) The support force at the top of the swing acting upwards
(2) The tension in the swing rope acting upwards
(3) The (normal) reaction between the legs of the swing frame and the ground
Explanation:
The normal reaction is the force equal in magnitude and opposite in direction to the total weight force the swing and the person on the swing posses due to gravitational attraction which prevents the downward or sideways motion of the entire swing
Answer:
If you change the number of neutrons in an atom, you get an isotope of the same element. The addition of a neutron can make an atom radioactive. When you change the number of protons in an atom, you will change the atom from one element to a different element.
