A big difference between Mathilde and Eros is that Mathilde represents a group of separate rocks whereas Eros is a solid rock.

<h3>What is an asteroid?</h3>

An asteroid is a celestial body composed of different types of rocky materials (generally clay but also silicate) and also metals (especially Fe).

An asteroid may have different sizes and some of them can be huge as dwarf planets that travel across the universe.

In conclusion, a big difference between Mathilde and Eros is that Mathilde represents a group of rocks whereas Eros is a solid rock.

A friend returns to the United states from Europe with a 960 W coffee maker, designed to operate from a 240 V line. What can she
Paladinen [302]

Answer:

\frac{N_2}{N_1}= 2

Explanation:

From the question we are told that:

Power W=960W

Voltage V=240v

USA-standard V_{usa}=120 V

Applying A step down transformer

Generally the equation for a Transformer is mathematically given by

 \frac{v_2}{v_1}c=\frac{N_2}{N_1}

 \frac{N_2}{N_1}=\frac{240}{120}

 \frac{N_2}{N_1}= 2

Therefore

She can use a turns ratio of 2

What increases as the temperature of a solid object rises?
atroni [7]
A. Thermal energy
Thermal energy is heat energy, therefore the hotter a solid is the more thermal energy it has.

C. Volume
When an object gets hotter, it expands. This is becuase the particles vibrate more and so are less compact.

A 100-kg astronaut is floating in outer space. If the astronaut throws a 2-kilogram wrench at a speed of 10 meters per second, w
sergey [27]

Since Astronaut and wrench system is isolated in the space and there is no external force on it

So here momentum of the system will remain conserved

so here we can say

m_1v_{1i} + m_2v_{2i} = m_1v_{1f} + m_2v_{2f}

initially both are at rest

so here plug in all values

0 = 100 v_{1f} + 2\times 10

v_{1f} = -0.20 m/s

so here the astronaut will move in opposite direction and its speed will be equal to 0.20 m/s

A particle charge of 2.7 µC is at the center of a Gaussian cube 55 cm on edge. What is the net electric flux through the surface
Alexxx [7]

Answer:

3.05×10⁵ Nm²C⁻¹

Explanation:

According to Gauss' law,

∅' = q/e₀............... Equation 1

Where ∅' = net flux through the surface, q = net charge, e₀ = electric permittivity of the space

From the question,

Given: q = 2.7 μC = 2.7×10⁻⁶ C,

Constant: e₀ = 8.85×10⁻¹² C²/N.m²

Substituting these values into equation 1

∅' = (2.7×10⁻⁶)/(8.85×10⁻¹²)

∅' = 3.05×10⁵ Nm²C⁻¹
