If a pushing force of 200 Nis required to cause the bicycle to start moving Would the pushing force increase, decrease or remains the same, when the area of contact between each tyre is increased to 40 cm2? Explain your answer.

What are the similarities & differences between a thermistor and a light dependent resistor in physics?

Amajor difference radio waves, visible light, and gamma rays is the of the photons, which results in different photon frequencies and wavelengths

An electron moves with a constant horizontal velocity of 3.0 × 106 m/s and no initial vertical velocity as it enters a deflector inside a tv tube. the electron strikes the screen after traveling 26 cm horizontally and 19 cm vertically upward with no horizontal acceleration. what is the constant vertical acceleration provided by the deflector? (the effects of gravity can be ignored.)
