The unit of electrical current is the ampere (A).

IrinaVladis [17]

Answer:

option B

Explanation:

Current unit is ampere (A)

Ampere will be equivalent to = ?

we know,

Current can be define as the charge per unit time

$I = \dfrac{Q}{t}$

unit of charge(Q) is coulomb which is equal to C.

unit of time(t) is equal to 's'.

now,

$I = \dfrac{C}{s}$

unit of I = C/s

ampere(A) is equivalent to C/s

The correct answer is option B

You estimate the radius of the big wheel to be 19 m

posledela

Explanation:

first, find the circumference of the wheel by using the formula 2(pi)(r):

2(pi)(19) = 119.380521

divide by 25 secs

119.380521/25 = 4.77522083

round to the nearest tenth is 4.8, so the speed is 4.8mm/sec

The type of chemical bond that involves the transfer of electrons between atoms is a(n) bond.

GaryK [48]

<h3>Answer;</h3>

<em>-Ionic bond</em>

<h3>Explanation;</h3>

<u>Ionic bond</u> is a type of bonds that results from transfers of electrons from one atom to another. This types of bond is formed between metals and non metals.
Metals lose electrons to form cations (positively charged ion) and non metals gain electrons forming anions, negatively charged ion.
For instance; between sodium and chlorine element; sodium donates a single electron to attain a stable configuration while chlorine gains an electron to achieve stable configuration, thus forming an ionic compound sodium chloride.
