Answer:
Explanation:
To calculate the time it took the car to hit the ground, we use the formula
speed = distance/time
80 m/s = 300 m/time
time = 300/80
time = 3.75 secs
It must have taken the car 3.75 seconds to hit the ground
To determine the horizontal distance of the car before hitting the ground, the same formula will also be used but with the time obtained above (since that was the time it took before hitting the ground)
speed = distance/time
80 = distance/3.75
distance = 3.75 x 80
distance = 300 meters

Answer:
Explanation: p = mass x velocity = m x v. • p = 1000 x 30 . The product of the force (F) acting on an object and applied force) A 1000 kg Civic is traveling at 30 m/s and ... What is the momentum of the car after accelerating for ... If a 5kg object experiences a 10 N force . Solve: Honda, Camry, collision ... v = -15 m/s
Answer:
2805 °C
Explanation:
If the gas in the tank behaves as ideal gas at the start and end of the process. We can use the following equation:
The key issue is identify the quantities (P,T, V, n) in the initial and final state, particularly the quantities that change.
In the initial situation the gas have an initial volume , temperature , and pressure ,.
And in the final situation the gas have different volume and temeperature , the same pressure ,, and the same number of moles ,.
We can write the gas ideal equation for each state:
and , as the pressure are equals in both states we can write
solving for
(*)
We know = 935 °C, and that the (the complete volume of the tank) is the initial volume plus the part initially without gas which has a volume twice the size of the initial volume (read in the statement: the other side has a volume twice the size of the part containing the gas). So the final volume
Replacing in (*)
Answer:
1.) Liquid
2.) Low
3.) Molecular
4.) Surface tension
5.) Solvent
Explanation:
Water is important to living things because it remains in the LIQUID state over a wide range of temperatures. Water in lakes and oceans does
not experience large temperature changes because liquid water has a
LOW specific heat, so it must absorb or release a lot of energy as its temperature changes. The MOLECULAR forces between water
molecules cause water to form round droplets and cause water's high SURFACE TENSION. Water is also an important SOLVENT because it can
dissolve many different substances.
