Answer:
6bar
Explanation:
According to pressure law;
P1/T1 = P2/T2
Given the following;
P1 = 1bar
T1 = 20oC
P2 = ?
T2 = 120oC
Substitute
1/20 = P2/120
20P2 = 120
P2 = 120/20
P2 = 6bar
Hence the new pressure will be 6bar
Your body is accelerating at the same speed as the car. If the car stops and there is nothing to restrain you, the inertia will cause your body to keep traveling at the same speed and you will fly forward, possibly through the windshield.
Answer:
radius of a circle is measured by an instrument, so it is the independent variable
Explanation:
The independent variable corresponds to the magnitude controlled by the experimenter and in general can be measured by an instrument.
The dependent variable is the variable used to perform the calculations, obtained from a mathematical transformation of the independent variable.
The radius of a circle is measured by an instrument, so it is the independent variable and the area is calculated by
A = π r²
Therefore the area corresponds to the dependent variable
Answer:
The speed is 20.70 mph.
Explanation:
Given that,
Speed = 6.7 m/s = 15 mph
In 10.4 m/s,
If 100 m record in 10.82 sec
We need to calculate the speed
Using formula of speed
Put the value into the formula
Hence, The speed is 20.70 mph.
