Answer:
To convert inches to centimeters, use an easy formula and multiply the length by the conversion ratio.
Since one inch is equal to 2.54 centimeters, this is the inches to cm formula to conver
Explanation:
Decibel<span> (dB) and, hearing loss levels can be anywhere like </span><span><span>-56 to -70 dB for Moderate/severe hearing loss, -</span><span>71 to -90 dB for Severe loss and</span><span> -91 dB for <span>Profound loss.</span></span></span>
Answer:20/47 meter per second
Explanation:
Mass of arrow(ma)=0.25kg
Velocity of arrow(va)=12m/s
Mass of target(mt)=6.8kg
Velocity of target(vt)=0 since target is at rest
Conservation of linear momentum says that :
maxva+mtxvt=(ma+mt)V
V=(maxva+mtxvt)/(ma+mt)
V=(0.25x12+6.8x0)/(0.25+6.8)
V=3/(7.05)
V=20/47 meter per second
Answer: 
Explanation:
Let's begin by explaining that the relation between the Celsius scale and Kelvin scale is:
This means the absolute zero point of the Kelvin scale is 
Keeping this in mind, we have the freezing point and boling point of Methane as:
Freezing point: 
Boiling point: 
According to this, there is a linear relation between the methane scale (
) and the Kelvin scale in the form:
(1)
Where:
is the temperature in Kelvin
is the temperature in degrees Methane
Firstly, we need to find the value of 
and 
with the two given points (
and 
):
When 
and 
:
(2)
When 
and 
:
(3)
Now we have the linear equation:
(4)
Isolating :
(5)
Evaluating for 
:
(6)
Finally:
This means 
Density formula is:
D = m / V
Volume of the matchbox car:
V = 46 ml - 41 ml = 5 ml = 0.005 l = 0.005 dm³
D = 10 g / 0.005 dm³
D = 2000 g / dm³ = 2 kg / dm³ = 2 × 10 ^(-3) kg/m³
