There are some mistakes in the question as units pressure and air density are not written correctly.The correct question is here
On a summer day in Narragansett, Rhode Island, the air temperature is 74°F and the barometric pressure is 14.5 lbf/in². Estimate the air density in kg/m³.
Answer:
p=1.175 kg/m³
Explanation:
Given data
Temperature =74 F
Barometric pressure=14.5 lbf/in²
To find
Air density
Solution
From ideal gas law
As mass/volume is pressure So
First we need to convert barometric pressure lbf/in² to N/m²
So
Now Substitute the given value and pressure to find air density
Answer:
Speed of the satellite V = 6.991 × 10³ m/s
Explanation:
Given:
Force F = 3,000N
Mass of satellite m = 500 kg
Mass of earth M = 5.97 × 10²⁴
Gravitational force G = 6.67 × 10⁻¹¹
Find:
Speed of the satellite.
Computation:
Radius r = √[GMm / F]
Radius r = √[(6.67 × 10⁻¹¹ )(5.97 × 10²⁴)(500) / (3,000)
Radius r = 8.146 × 10⁶ m
Speed of the satellite V = √rF / m
Speed of the satellite V = √(8.146 × 10⁶)(3,000) / 500
Speed of the satellite V = 6.991 × 10³ m/s
Answer:
bias refers to effects that a conclusion that may be incorrect, as for example when a researcher patient knows what treatment is being given, to avoid bias a blinded study may be done
According to Joule's Law, we have the relationship between charge, voltage, and current:
W = Vq
where q is the charge
V is the voltage or the potential difference
W is the work done
From the given values and rearranging the equation:
V = 10J / 4.0x10^-2
V = 250 V
The voltage difference is 250 V
Answer:
Stooping more Quickly
Explanation: Stooping more quickly means that Motor cycles can easily bend and stop,this is due to it's design, Motor cycle have only two wheels,they contain just two tyres one in front and one at the back,they are not as firm on the ground when compared to other vehicles such Motor car. They have a lower weight which makes them easily bent or stopped once there's any barrier.
