Answer:
Explanation:
Most of this water is locked up in ice, and another 20.9% is found in lakes. Rivers make up 0.49% of surface freshwater. Although rivers account for only a small amount of freshwater, this is where humans get a large portion of their water from.
Answer:
Explanation:
B. Turn the steering wheel while the car is moving.
causes centripetal acceleration.
C. Press the gas pedal while the car is stopped.
causes forward acceleration.
D. Press the brake pedal while the car is moving.
causes rearward acceleration.
Some physical properties of matter include viscosity (maple syrup is more viscous than oil), color (an apple can be red, while a watermelon is green), opacity (a computer screen is more opaque than a window), and freezing point (ice with salt has a lower freezing point than plain ice).
Some chemical properties include pH (milk of magnesia v. wine), and heat of combustion.

Troposphere. The troposphere is the lowest layer of our atmosphere.
Stratosphere. The infamous ozone layer is found within the stratosphere.
Mesosphere. Most meteors burn up in the mesosphere.
Thermosphere. Many satellites actually orbit Earth within the thermosphere
Exosphere. Considered to be the actual "final frontier"
Ionosphere. The electrically charged atoms and molecules that are formed in this way are called ions, giving the ionosphere its name
The downward force on the 2. 67-cm piston that is required to lift a mass of 2000 kg supported by the 20-cm piston is 350 N.
<h3>What is pascal law?</h3>
Pressure applied to a closed system of fluid will be transfer at each point of the fluid and the boundaries of the system.
Let suppose at the two point of such system the input force apllied is F₁ and output force we get is F₂. The area of this points is A₁ and A₂ respectively. As the pressure at both point is same. Then by the pascal law,
In case of radius,
Two pistons of a hydraulic lift have radii of 2. 67 cm and 20. 0 cm, respectively. Thus,
The downward force on the 2. 67-cm piston that is required to lift a mass of 2000 kg supported by the 20-cm piston is The force applied on second piston is,
Put the values in the above formula,
Thus, the downward force on the 2. 67-cm piston that is required to lift a mass of 2000 kg supported by the 20-cm piston is 350 N.
