Ques

Amanda [17]

Answer:

When a particle or a system of particles move in a system where no external force acts, then the total linear momentum of the particle system remains constant.

Explanation:

Given data:

Total mass of the skateboarder, $m_{1} = 70 \ kg$

Mass of the friend, $m_{2} = 50 \ kg$

Initial velocity of the skateboarder, $u_{1} = 3 \ m/s$

Initial velocity of the the friend, $u_{2} = 0$

Let the new velocity of the skateboarder when his friend jumps be $v$ .

From the conservation law of linear momentum,

$m_{1}u_{1} + m_{2}u_{2} = (m_{1} + m_{2})v$

$70 \times 3 + 50 \times 0 = (70 + 50)v$

$\Rightarrow \ v &= 1.75 \ m/s.$

A 0.200 kg block on a vertical spring with spring constant of 4.65 ✕ 103 N/m is pushed downward, compressing the spring 0.084 m.

vlada-n [284]

Answer:

PEel = PEg

PEel = .5 * k * x^2

= .5 * 4650 * .1^2

= 23.25

PEg= m * g * h

=.2 * 9.81 * h

23.25 = 1.962* h

h = 11.85

irina1246 [14]

Answer:

D. The sum total of all matter and energy

Explanation:

The universe is defined as a closed system that contains all forms of energy and matter. Therefore, includes the so-called dark matter and dark energy, which make up most of the universe, since ordinary matter would only represent just over 5% of the total.
