Answer: Time needed: 2.5 s
Distance covered: 31.3 m
Explanation:
I'll start with the distance covered while decelerating. Since you know that the initial speed of the car is 15.0 m/s, and that its final speed must by 10.0 m/s, you can use the known acceleration to determine the distance covered by
on one side of the equation and solve by plugging your values
To get the time needed to reach this speed, i.e. 10.0 m/s, you can use the following equation
Explanation:
The water displacement method is a set of measurements used to calculate the volume of an irregularly shaped object. These objects are commonly known as irregularly shaped solids.
<h3>What is water displacement method ?</h3>
The displacement method (also known as the submersion or dunking method) can be used to accurately measure the volume of the human body and other irregularly shaped objects by measuring the volume of fluid displaced when the object is submerged.
Place your jewelry on a table or in your hand, and pour some white vinegar directly on the metal (a dropper can also be used). If the metal of the jewelry changes color, it is not pure gold; if it continues to shine, you have real gold in your hand.
Thus, The water displacement method is a set of measurements used to calculate the volume of an irregularly shaped object.

Answer:
n= 0.08186
{He}2s^2 2p^6
Explanation:
PV=nRT
n=PV/RT
n= (1.220 atm)(4.3410 L) / (0.0821 atm*L/mol*K)(788.0 K)
n=0.08186
As for the electron configuration:
Ne:
{He} 2s^2 2p^6
or long hang:
1s^2 2s^2 2p^6
Equation#1 - Ca(s)+Cl2(g) ——> CaCl2(s)
Word equation #1- Calcium and Chlorine react to form Calcium Chloride.
Equation #2- N + I3 —-> I3N
Word Equation #2- Nitrogen and Iodine react to form nitrogen triiodine.
Answer:
because not enough of the parent isotope remains to measure accurately. because not enough of the daughter product has formed to be detectable.
