Answer:

Explanation:

Waves can be measured using wavelength and frequency. The distance from one crest to the next is called a wavelength. The number of complete wavelengths in a given unit of time is called frequency. As a wavelength increases in size, its frequency, and energy decrease.

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 car is traveling at a steady 73 km/h in a 50 km/h zone. A police motorcycle takes off at the instant the car passes it, accele

iVinArrow [24]

Answer:

29 m

Explanation:

given,

speed of the car = 73 Km/hr

= 73 x 0.278 m/s = 20.3 m/s

Time elapses before the motorcycle is moving as fast as the car

using equation of motion

v = u + at

initial speed = 0 m/s

20.3= 0 + 7 x t

t = 2.9 s

b) distance traveled by the car in that time

d = s x t

d = 20.3 x 2.9 = 58.87 m

distance traveled by the police

$s = ut + \dfrac{1}{2} a t^2$

$s = 0 + \dfrac{1}{2}\times 7\times 2.9^2$

s = 29.435 m

distance car is ahead = 58.57 - 29.44 = 29.13

= 29 m
