If an object has a net positive charge of 4.0 coulombs, the object possesses (1) 6.3 × 10^18 more electrons than protons (2) 2.5
Readme [11.4K]

Answer:

(4) 2.5 \times 10^{19} more protons than electrons

Explanation:

Total positive change on the object is given as

Q = 4 C

now by the law of quantization of charge we know that the charge on any body is always in form of integral multiple of charge of an electron.

So we will have

Q = N e

here we know that

4 = N(1.6 \times 10^{-19})

N = 2.5 \times 10^{19}

Now we know that the object is positively charged so here electrons must be less in numbers than protons

so correct answer will be

(4) 2.5 \times 10^{19} more protons than electrons

What is the net force? <br><br> URGENT! thank you
alexandr402 [8]
Net force is the vector sum of forces acting on a particle or body. The net force is a single force that replaces the effect of the original forces on the particle's motion. It gives the particle the same acceleration as all those actual forces together as described by the Newton's second law of motion.

A 500g air-track glider attached to a spring with spring constant 10 N/m is sitting at rest on a frictionless air track. A 250 g
d1i1m1o1n [39]

To solve this problem it is necessary to apply the conservation equations of the moment for an inelastic impact or collision. In turn, it is necessary to apply the equations related to the conservation of potential energy and kinetic energy.

Mathematically this definition can be expressed as

m_1v_1+m_2v_2=(m_1+m_2)v_f

Where,

v_{1,2} = Initial velocity of each object

m_{1,2} =Mass of each object

v_f =Final velocity

Our values are given as

m_1 = 0.25kg\\m_2 = 0.5kg\\v_1 = 1.2m/s\\v_2 = 0m/s

Replacing we can find the value of the final velocity, that is

0.750v_f = 0.25*1.20+0.5*0

v_f = 0.4m/s

From the definition of the equations of simple harmonic motion the potential energy of compression and equilibrium must be subject to

KE_{compressed}+PE_{compressed} =KE_{equilibrium} +PE_{equilibrium}

Since there is no kinetic energy due to the zero speed in compression, nor potential energy at the time of equilibrium at the end, we will have to

0+\frac{1}{2}KA^2 = \frac{1}{2}(m_1+m_2)v_f^2+0

Re-arrange to find A

A = \sqrt{\frac{m_1+m_2}{k}v_f}

A = \sqrt{\frac{0.25+0.5}{10}(0.4)}

A = 0.11m

Finally, the period can be calculated through the relationship between the spring constant and the total mass, that is,

T = 2\pi \sqrt{\frac{m_1+m_2}{k}}

T = 2\pi \sqrt{\frac{0.5+0.25}{10}}

T = 1.7s

What is the ground and why is the ground important<br>​
Anna71 [15]
The ground is a foundation for many of the things of our lives. It is the foundation for the buildings in our life such as our houses, schools, work, hospital, and so on. It is the foundation for our lives that we often take for granted and it nurtured the trees and nature around us.
