Respuesta:
$138.39
Explicación:
Paso 1: Calcular el total que gastaron
El total que gastaron es igual a la suma de los que gastó cada uno.
$50.00 + $28.50 + $20.50 + $10.80 + $22.00 = $131.80
Paso 2: Calcular el 5% de $131.80
$131.80 × 5% = $6.59
Paso 3: Calcular el total que pagó con la tarjeta
A los $131.80 que gastaron debe sumarle los $6.59 por el uso de tarjeta.
$131.80 + $6.59 = $138.39
Answer:
The Electron
Explanation:
Electrons are how some atoms let electricity flow easily. If have closely bound electrons, then they are a bad conductor, or insulator. Atoms with loosely bound electrons allow electricity to easily flow, making these types of atoms great conductors. This is the case with most metals, where their electrons are very loose, making metals, like copper, great at transmitting electricity.
Answer:

Explanation:
Maximum distance after which the motorist must have to stop is given as

now the distance after which the vehicle will stop on applying breaks is given as



now remaining distance is given as


now reaction time is given as



Answer:
a) 
Explanation:
Given paraeters are:
R = 25 cm
d = 4.7 mm
f = 60 Hz
= 160 V
a) 
Where
Hz and
V

For 

Since 

From Ampere's Law:
where 
So at
,

For maximum B, cos(2πft) = 1. Hence,
T
b) From r = 0 to r = R = 0.025 m, by Ampere's Law, the equation will be:

From r = R = 0.025 m to r = 0.1 m, by Ampere's Law, the equation will be:

The plot is given in the attachment.
<span>the gravational potential energy of anything on the ground is zero. When calculating potential energy you take height in meters and multiply it by the mass of the object in kilograms and the acceleration of gravity to get a new unit called Joules.
Any object at ground level has a potential energy of zero newtons becuase anything multiplied by zero is zero. An object with mass of 54 kg, 4 meters above the ground has a gravitatinal potential energy of 2116.8 Joules.</span>
