Answer:
The final speed of bicycle would be <u>27 m/s</u>².
Step-by-step explanation:
<u>Given</u> :
Initial velocity (u) = 15 m/s
Acceleration (a) = 3.0 m/s²
Time = 4 seconds
<u>To</u><u> </u><u>Find</u> :
Final velocity (v)
<u>Using</u><u> </u><u>Formula</u> :

v = final velocity
u = initial velocity
a = acceleration
t = time taken
<u>Solution</u> :
Substituting the values in the formula to find the final velocity :







Hence, the final speed of bicycle would be 27 m/s².

The mass of hydrogen in 57.010 g ammonium hydrogen phosphate, (NH₄)H₂PO₄ is 2.97 g
<h3>Determination of mass of 1 mole of (NH₄)H₂PO₄ </h3>
1 mole of (NH₄)H₂PO₄ = 14 + (4×1) + (2×1) + 31 + (16×4) = 115 g
<h3>Determination of the mass of H in 1 mole of (NH₄)H₂PO₄ </h3>
Mass of H = 6H = 6 × 1 = 6 g
<h3>Determination of the mass of H in 57.010 g of (NH₄)H₂PO₄ </h3>
115 g of (NH₄)H₂PO₄ contains 6 g of H.
Therefore,
57.010 g of (NH₄)H₂PO₄ will contain = (57.010 × 6) / 115 = 2.97 g of H
Thus, 2.97 g of Hydrogen, H is present in 57.010 g of (NH₄)H₂PO₄

Three equally spaced points ( . . . ) often used to represent an omission of words in a quotation are best known as ellipsis. They are also known as ellipsis dots, suspension points, or simply ellipsis.
<h3>Usage</h3>
"For example, I may be writing an article to be published in a journal and not include ellipsis. . ."
In summary, we utilise ellipsis to indicate that a list goes on beyond those items actually spelled out in the text.
