The greatest percent of mass of the universe is dark matter
The jogger's average speed 1.03 m/s
<h3>
The Speed and the Velocity of a Particle in a Circle</h3>
The speed of a particle is a circle will always be constant while the velocity will not. That is, velocity varies.
Given that a jogger jogs around a circular track with a diameter of 275 m in 14.0 minutes. First convert the minutes to seconds
Given parameters are;
- Time t = 14 minutes = 14 x 60s = 840 s
Speed V = 2πr ÷ t
V = ( 2 × π × 137.5 ) ÷ 840
V = 863.9 / 840
V = 1.028 m/s
Therefore, the jogger's average speed 1.03 m/s approximately

Answer:
Explain how sociology will contribute to the understanding of daily life and what is happening within it?
Sociology is the study of society of human being, how they develop and those things put in place for such development
Explanation:
Sociology helps to develop culture, how people interact with one another and this boost the relationship and development as far as human society is concerned.
Both masses will have the same acceleration. The cart accelerates to the right with a magnitude of 4.9 m/
. The correct answer is 4.90 m/
Given that a massless string connects a 1.00 kg mass to a 3.00 kg cart which is resting on a frictionless horizontal surface.
Let M = 1kg and m = 3 kg
Since the horizontal surface is frictionless, the tension in the string will be the same. when the mass is hanged over a frictionless pulley, the tension will also be the same.
When the mass is released, the cart accelerates to the right can be calculated from Newton' second law of motion. That is,
M( g + a) = m(g - a)
1(9.8 + a) = 3( 9.8 - a)
9.8 +a = 29.4 - 3a
collect the like terms
4a = 19.6
a = 19.6/4
a = 4.9 m/
Therefore, the cart accelerates to the right with a magnitude of 4.9 m/. The correct answer is 4.90 m/
