Answer:
The combined velocity is 8.61 m/s.
Explanation:
Given that,
The mass of a truck, m = 2800 kg
Initial speed of truck, u = 12 m/s
The mass of a car, m' = 1100 kg
Initial speed of the car, u' = 0
We need to find the combined velocity the moment they stick together. Let it is V. Using the conservation of momentum.
So, the combined velocity is 8.61 m/s.
Answer:
Bnet=1.006*10^-6T
Explanation:
One long wire lies along an x axis and carries a current of 43 A in the positive x direction. A second long wire is perpendicular to the xy plane, passes through the point (0, 5.9 m, 0), and carries a current of 41 A in the positive z direction. What is the magnitude of the resulting magnetic field at the point (0, 1.7 m, 0)?
the magnetic field Bnet=
the magnetic field due this long wire is given by
B1=∨I1/..............................1
B2=∨I2/............................2
Bnet=.......................3
Bnet=v/2*pi
Bnet=4*pi*10^-7/(2)
Bnet=0.0000002*(641.72)^.5
Bnet=1.006*10^-6T
Answer:
a) The equivalent temperature of 2000 ºC is 3632 ºF.
b) The equivalent temperature of 2000 ºC is 4091.67 R.
c) The equivalent temperature of 2000 ºC is 2273.15 K.
d) The equivalent temperature of 2000 ºC is 1600 ºRe.
Explanation:
a) The equivalent temperature on the Fahrenheit scale is defined by the following formula:
(Eq. 1)
Where:
- Temperature, measured in degrees Celsius.
- Temperature, measured in degrees Fahrenheit.
If we know that , then the temperature is:
The equivalent temperature of 2000 ºC is 3632 ºF.
b) From result in a) we determine the equivalent temperature on the Rankine scale by using the following formula:
(Eq. 2)
Where:
- Temperature, measured in degrees Fahrenheit.
- Temperature, measured in Rankine.
If we know that , then the temperature is:
The equivalent temperature of 2000 ºC is 4091.67 R.
c) The equivalent temperature on the absolute scale is calculated by using this expression:
(Eq. 3)
Where:
- Temperature, measured in degrees Celsius.
- Temperature, measured in Kelvin.
If we know that , then the temperature is:
The equivalent temperature of 2000 ºC is 2273.15 K.
d) The equivalent temperature on the Réaumur scale is calculated by applying this expression:
(Eq. 4)
Where:
- Temperature, measured in degrees Celsius.
- Temperature, measured in degrees Réaumur.
If we know that , then the temperature is:
The equivalent temperature of 2000 ºC is 1600 ºRe.
