Answer:
(b) 2.40 x kg/s
Explanation:
Given that: Total mass of the rocket = 3.003 x kg
acceleration of the rocket = 36.0 m
speed of the exhausted gases = 4.503 x m/s
Rate at which rocket was initially burning fuel =
But,
time =
=
= 125.0833 s
So that;
Rate at which rocket was initially burning fuel =
= 2400.8001
= 2.40 x kg/s
Therefore, the initial rate at which the rocket burn fuel is 2.40 x kg/s.
Answer:
B. is subject to a smaller net force but same acceleration.
Explanation:
F = m*a
So because our force applied is constant from the women pulling on the rope which means the acceleration is the same on both the 4kg create and the 6kg create. The only thing that changes here is the mass of the creates, so there is more tension force between the women and the 6kg create then there is between the 4kg create and the 6kg. It takes less force to move the 4kg create therefore the tension force is less between the two creates.
Answer:
(a) 0.0225 kg m^2
(b) 0.5 kg
Explanation:
Diameter, d = 60 cm
radius, r = 30 cm = 0.3 m
KE = 0.250 J
f = 45 rpm = 45/60 rps = 0.75 rps
(a)
Angular velocity, ω = 2 x π x f = 2 x 3.14 x 0.75 = 4.71 rad/s
Where, I be the moment of inertia
0.250 = 0.5 x I x 4.71 x 4.71
I = 0.0225 kg m^2
Thus, the moment of inertia of the disc is 0.0225 kg m^2.
(b) Let m be the mass of disc.
Moment of inertia of the disc is
I = 0.5 x m x r^2
0.0225 = 0.5 x m x 0.3 x 0.3
m = 0.5 kg
Thus, the mass of the disc is 0.5 kg.
All traditional oriental medicine recognizes that an energy force called Qi flows through the body.
Traditional Chinese medicine is predicated on the idea that qi, or the body's life force, travels along meridian channels and maintains equilibrium in a person's physical, mental, emotional, and spiritual well-being. The Feldenkrais technique is a type of somatic education that combines focused attention and gentle movement to improve human function and mobility. You can broaden your range of motion, boost your comfort level, and enhance your flexibility and coordination by using this method. This could involve your food, your workout routine, psychotherapy, relationship counseling, and more. therapies that are complementary or alternative, including acupuncture, chiropractic adjustments, homeopathy, massage, naturopathy, and others.
