A fatter handle. This allows you to provide more torque to the screw, which should eventually loosen it.
Answer:
Explanation:
F₁ = Force on one side of the jack
A₁ = Area of cross-section of one side of the jack
F₂ = Force on second side of the jack
A₂ = Area of cross-section of second side of the jack = 2 A₁
Using pascal's law
A = dv/dt = ak
ak = ( 0.0 m/s - 9.0 m/s ) / ( 3 s )
3m/s^2
Answer:
when the water is heated with immersion heater, the water becomes less dense due to which the warm water rises up and the cooler water fills it's space.
Answer: The correct answer is " longitudinal wave with air molecules
vibrating parallel to the direction of travel".
Explanation:
In longitudinal wave, the particles vibrate parallel to the direction to the propagation of the wave. For example, sound wave is a longitudinal wave.
It needs a medium for its propagation. It can travel in solid, liquid and gas. It travel faster in solid in comparison to the liquid.
In the given problem, a tuning fork vibrates at a frequency of 512 hertz when struck with a rubber hammer. The sound produced by the tuning fork will travel through air. Here, a longitudinal wave with air molecules vibrating parallel to the direction of travel.
Therefore, the correct option is (1).
