Solar energy is incident on the top of earth’s atmosphere at the rate of about 1,360 watts on every square meter (w/m2). This energy effectively falls on the cross-sectional area of the planet. From this fact, calculate the total rate at which solar energy arrives at earth. you’ll need to find earth’s radius

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.)
