The answer is A. Force is equal to mass x acceleration. The acceleration due to gravity is a constant so multiplying the mass by 2 would double the force.
Answer:
the affirmation is False
Explanation:
This expression can be analyzed using Newton's laws and specifically Newton's third law that establishes that the force that one body (1) exerts on another body (2) is of the same magnitude as the force exerted by the second body on the first, but in the opposite direction.
Based on this law, the body applies a force to the box and the box reacts with a force on the string of equal magnitude, no matter if it is moving or not, but it contrary direction,
in view of this explanation the affirmation is False
Burning is a chemical change, and this changed the chemical properties of the wood. Indicators that chemical change has taken place are fizzing, energy being given off or color changes.
Answer:
Explanation: Speed = Wavelength x Wave Frequency. In this equation, wavelength is measured in meters and frequency is measured in hertz (Hz), .
Answer:
Due to brown knob which controls its angle.
Explanation:
When water comes out at an angle instead of going straight up, water does not shoot as high as before because its speed is controlled by the brown knob in order to throw water in another angle. If we adjust the brown knob present at the opening of hose pipe in a straight angle the water shoot very high because water moves with high pressure and no barrier is present between its way.
