The density (d) of a substance is calculated by dividing the mass (m) by the given volume (v). Mathematically,
d = m / v
Substituting the known values,
d = 374 g / (2.2 x 10^3 L) = 0.17 g/L
Thus, the density of the weather balloon is 0.17 g/L.
Answer:
It will take 40 seconds to catch the speeding car
Explanation:
Initial speed of the patrolman = 55 mph
after one minute speed of patrol man = 115 mph
now acceleration of patrolman is given by
now at this acceleration the distance covered by patrolman in "t" time is given as
now we know the speed of the speeding car is given as
now in the same time distance covered by it
now since the distance covered is same
Velocity can be calculated using the following rule:
velocity = lambda * frequency where:
velocity is given = 6 km/sec
lambda is the wavelength that we want to calculate
frequency is given = 13 Hz
Substitute with the givens in the above equation to get the wavelength (lambda) as follows:
6 = 13*lambda
wavelength = 6/13 = 0.461538 Km = 461.538 meters
An ocean's salinity is affected by water and air temperature, the volume of water that flows into it, its age and the chemical composition of surrounding geological formations.<span> Because the effect of these factors varies over the area of an ocean, different levels are found within the ocean</span>
Habitat preservation is when people get together or just one person helps to stop the end of a living space for animals such as the monterey aquarium the help sea life by doing research to see why animals are dying and do what they can to stop it. another one if nation parks or forests you are not allowed to harm them in any way they are protected by laws(the government)
