Compare the number of electrons with the number of protons in a charged object.

1 answer:

4 0

If the object is negatively charged it means it has gained electron so negatively charged object has more number of electron than proton

If the object is positively charged it means it has lost electron so positively charged object has more number of proton than electron

What speed would a fly with the mass of 0.55 g need in order to have the same kinetic energy as the automobile in the term 19

larisa86 [58]

The question does not provide enough information to complete the answer, so I'll assume the needed data to help you to solve your own problem

Answer:

The fly should need to move at 9,534.6 m/s to have the same kinetic energy as the automobile

Explanation:

Kinetic Energy

Is the capacity of a body to do work due to its speed and is computed by

$\displaystyle K=\frac{mv^2}{2}$

We are not given enough data to compare the kinetic energy of the fly with that of the automobile. We'll assume the following characteristics:

$m_a=500\ kg$

$v_a=10\ m/s$

So its kinetic energy is

$\displaystyle K_a=\frac{(500)10^2}{2}$

$\displaystyle K_a=25,000\ J$

The mass of the fly is

$m_f=0.55\ gr=0.00055\ kg$

To have the same kinetic as the automobile:

$\displaystyle \frac{m_fv_f^2}{2}=25,000$

Solving for $v_f$

$\displaystyle v_f=\sqrt{\frac{2(25,000))}{m_f}}$

$\displaystyle v_f=\sqrt{\frac{50,000}{0.00055}}$

$v_f=9,534.6\ m/s$

The fly should need to move at 9,534.6 m/s to have the same kinetic energy as the automobile

Explain the relationship between electrical charge and force.

Radda [10]

The relationship between electrical and charge force is that electrical force strengthens and increases the energy pulses and reflects off an object and makes the force about two times greater with charge.

What property of light is suggested by the formation of shadows

Mandarinka [93]

Answer:

The reflection and rectilinear propagation of light helps in the formation of shadows and also tells light doesn't penetrate opaque materials.
