Stolb23 [73]3 years ago
6 0

Answer:

Direct coupling

Explanation:

Direct coupling is sensitive to changes that occurs in temperature. It is electrical energy transfer using physical contact through a medium that is conductive.

It is useful in the interconnection of 2 circuits. This kind of coupling method can be done by a wire, a resistor or through mettalic bonding.

Select the correct answer. if two half-lives have passed since a scientist collected a 1.00-gram sample of u-235, how much u-235
Ugo [173]

Answer:

0.25 g of U-235 isotope will left .

Formula used :

where,

N = amount of U-235 left after n-half lives = ?

= Initial amount of the U-235 = 1.00 g

n = number of half lives passed = 2

0.25 g of U-235 isotope will left .

Write structural formulas for each of the possible isomers of n-hexene that are formed by moving the position of the double bond
dem82 [27]

Answer : The structural formulas for each of the possible isomers of n-hexene are shown below.

Explanation :

Isomer : It is defined as a molecule have the same molecular formula but the different chemical structure.

There are three structural isomers of n-hexene that is based on the location of the double-bonded carbon atoms with the other atoms.

In n-hexane, 'n' shows that the chain should be straight chain there is no branching.

The three structural isomers of n-hexene are:

(1) 1-hexene

(2) 2-hexene

(3) 3-hexene

Thus, the structural formulas for each of the possible isomers of n-hexene are shown below.

A 10-ft moving truck has a volume capacity of 402 cubic feet, which is equivalent to 1.138 x 10^7 milliliters. What
ELEN [110]

Answer: The mass of silver is 1.19 X 10^14 M g

Explanation: The volume of the truck is 402 cubic feet or 1.138 x 10⁷ mm.

The density of silver is 10.49 g/mL.

We need to find the mass of silver that will fit in this moving truck. Density equals mass divided by volume. So,

<h2>d= m/v where m= mass m= d x V</h2><h2>M=10.49 g/mL X 1.138 X 10∧7 mL</h2>

M=119376200 g  1 gram=10⁻⁶ Megagram 119376200= 1.19 X 10^14 Mg hence the mass of silver is 1.19 X 10^14 M g hopefully this will help you please mark me as brainlist
