A 12 volt battery in a motor vehicle is capable of supplying the starter motor with 150 A. It is noticed that the terminal volta

qwelly [4]

Answer: $0.0133 \Omega$

Explanation:

Given

Voltage=12 V

Current(I)=150 A

$V_{terminal}=10 V$

$r_{internal}=\frac{\Delta V}{I}$

$r_{internal}=\frac{12-10}{150}$

$r_{internal}=\frac{2}{150}=0.0133 \Omega$

1. The head of a rattlesnake can accelerate 50.0 m/s in striking a victim. If a car could do

Maslowich

Answer: 0.492 s

Explanation:

We can use the following equation to solve this problem:

$V=V_{o}+a.t$

Where:

$V=24.6 m/s$ is the car’s final velocity

$V_{o}=0 m/s$ is the car’s initial velocity (it starts from rest)

$a=50 m/s^{2}$ is the car's acceleration

$t$ is the time we have to find

Isolating $t$ :

$t=\frac{V-V_{o}}{a}$

$t=\frac{24.6 m/s-0 m/s}{50 m/s^{2}}$

Finally:

$t=0.492 s$

An observation which is descriptive is considered

oksano4ka [1.4K]

A descriptive observation may very well be a mixture of both quantitative and qualitative as it can utilize elements of both types. Qualitative deals with the kinds of observations that cannot be measured in numerical form. Quantitative data is just that.
