Arace car has a speed of 80 m/s when the driver releases a drag parachute. if the parachute causes a deceleration of 4m/s^2, how far will the car travel before it stops?

Alinearly polarized electromagnetic wave has an average intensity of 196 w/m^2. this wave is directed towards two ideal polarizers (in real polarizers, transmission is also effected by reflection and absorption). polarizer a is oriented with its transmission axis at an angle of θ_1=20.8∘ with the incident electric field. polarizer b has its axis at an angle of θ_2=63.0∘ with the incident electric field. what is the average intensity of the wave after it passes through polarizer a? what is the average intensity of the wave after it passes through polarizer b? suppose that the two polarizers a and b are interchanged. what would the average intensity be after passing through both polarizers?

We put a force of 50n on an object and the acceleration is 100 m/s². what is the mass of the object?

Smallest intensity of a stimulus that you can detect 50 percent of the time is
