Atoms that are bonded together to form a new material with new properties and characteristics. .

mihalych1998 [28]

Answer:

Explanation:

Atoms form chemical bonds to make their outer electron shells more stable. ... An ionic bond, where one atom essentially donates an electron to another, forms when one atom becomes stable by losing its outer electrons and the other atoms become stable (usually by filling its valence shell) by gaining the electrons.

In what ways does a stream transport its load, and which part of the load moves most slowly? Select all that apply.

vodka [1.7K]

Answer: Option (B)

Explanation: A stream transports its materials in different ways-

Dissolved load- Here, the materials gets dissolved when mixed with water and flows along with the stream.
Suspended load- Here, the materials are not fully dissolved in the water but they can be carried from one place to another in suspension mode, by the river.
Bed load- Bed load are transported in three different ways such as-

Sliding- here, the materials slides down along a curved surface under the water and carried away.
Rolling- here, the materials are solid and due to force exerted by water, it can roll and move to distant places.

Saltation- here, the materials are carried away in a series of jumps.

Thus, the most appropriate answer is option (B) i.e bedload.

A very humble bumble bee is flying horizontally due North at a constant speed of 3.11 m/s. At the current location of the bumble

Reil [10]

To solve this problem we will apply the concepts of the Magnetic Force. This expression will be expressed in both the vector and the scalar ways. Through this second we can directly use the presented values and replace them to obtain the value of the magnitude. Mathematically this can be described as,

$\vec{F_B} = q(\vec{V}\times \vec{B})$

$F_B = q|v||B| sin\theta$

Here,

q = Charge

v = Velocity

B = Magnetic field

$\theta = \text{Angle between } \vec{B} \text{ and } \vec{V}$

Our values are given as,

$\theta = 35.7\°$

$q = 22.5*10^{-9}C$

$B = 1.05*10^{-5}T$

$v = 3.11m/s$

Replacing,

$F_B = (22.5*10^{-9}C)(3.11 \times 1.05*10^{-5}) sin(35.1\°)$

$F_B = 4.224*10^{-13}N$

Therefore the size of the magnetic force acting on the bumble bee is $4.22*10^{-13}N$
