Suppose you have a car with a battery that applies 12.5 V to the starter.

Marat540 [252]

Answer:

R = 0.1 ohms

Explanation:

It is given that,

Voltage of the battery, V = 12.5 V

Current flowing in the car's starter, I = 125 A

We need to find the effective resistance of a car's starter. It can be calculated using Ohm's law. Let R is the resistance.

$V=IR\\\\R=\dfrac{V}{I}\\\\R=\dfrac{12.5}{125}\\\\R=0.1\ \Omega$

So, the resistance of the car's starter is 0.1 ohms.

A ball is thrown straight up with an initial speed of 36 m/s . Part A How much time does it take for the ball to reach the top o

nevsk [136]

Answer:3.67 s

Explanation:

Given

Ball is thrown with an initial velocity of $u=36\ m/s$

As the ball moves upward it experience a declaration due to gravity which will slow down the ball

using

$v=u+at$

where v=final velocity

u=initial velocity

a=acceleration

t=time

Here $v=0$

$0=36-9.8\times t$

$t=\frac{36}{9.8}$

$t=3.67\ s$

The black lines that wrap themselves around a basketball represent an example of what type of geometry?

Dmitry [639]

In Euclidean geometry parallel lines never intersect. But in non-Euclidean geometry parallel lines can either curve away from each other, or curve towards each other. Example : the black lines that wrap themselves around the basketball.
Answer: B ) non-Euclidean
