Answer:
FLASH FLOODS CAN CAUSE VEHICLES TO FLOAT AND FILL WITH WATER, TRAPPING AND DROWNING PEOPLE. WHILE ESPECIALLY DANGEROUS AT NIGHT AND IN DEEP WATER, EVEN ____ INCHES OF WATER CAN FLOAT SOME SMALL CARS.
The Answer is SIX Inches.
Explanation:
Flash floods: are short-term events and are associated with short, high-intensity rainfall which occur when creeks that are normally dry fill up and other creeks overflow. Densely populated areas have a high risk of flash floods. Water levels in flash floods can rise one foot in five minutes making Six inches of water able to reach the bottom of most passenger cars. Moving water will exert pressure on a car. The car floats downstream when stream force exceeds the friction force, the car will be carried when bouyancy force (which is the upward force exerted by any fluid upon a body placed in it) is greater than vehicle weight.
c.The warm surface water results in moist air and more rainfall.
Explanation:
- During upwelling, cold water in the ocean is stirred up and brought to the surface.
- The warmer surface water is then taken into deeper parts of the ocean.
- Upwelling allows for nutrient mixing in the ocean and allows for useful gases to circulate well.
- The warm surface water causes the air to be moisty.
- When the air is carried landward towards the coast, it leads to rainfall when the saturated air releases the water.
- The air then becomes cold and dry and it rises up.
- Therefore, warm surface water results in moist air and more rainfall.

Answer:
a= 17.877 m/s² : Magnitude of the acceleration of the flea
β = 88.21° : Direction of the acceleration of the flea
Explanation:
Conceptual analysis
We apply Newton's second law:
∑F = m*a (Formula 1)
∑F : algebraic sum of the forces in Newton (N)
m : mass in kilograms (kg)
a : acceleration in meters over second square (m/s²)
Problem development
Look at the flea free body diagram in the attached graphic
The acceleration is presented in the direction of the resultant force (R) applied over the flea .
R= 10.905*10⁻⁶ N
We apply the formula (1) to calculate the magnitude of the acceleration of the flea
∑F = m*a m = 6.1 * 10⁻⁷ kg
R = m*a
a= R/m
a= (10.905*10⁻⁶) / (6.1 * 10⁻⁷ )
a= 17.877 m/s²
β: Direction and magnitude of the acceleration of the flea
β = 88.21°
Answer:
47347.1936 milligrams per centimeter
Explanation:
1 pound is equal 453592 milligrams.
one meter is 100cm
10.43*453952/100= 47347.1936milligrams per cm
