A force of 150 N is used to push a motorcycle 10 m along a road in 20 s. Calculate WORK done in joules.

(Work = Force x Distance)

Calculate POWER in Watts

(Power = Work / Time) Work = 75 Watts

Power = 1500 Joules

Work = 1500 Joules

Power = 75 Watts

Work = 1500 Joules

Power = 1500 Watts

Work = 3000 Watts

Power = 75 Joules

(2) (a) you have a simple circuit that consists of only a battery (δvbat=1.5v) and two resistors with resistance r1=10ω and r2=5ω, connected in series with each other. what is the current running through the battery? (b) you re-arrange your circuit so now r2 is attached in parallel to r1 rather than in series. what is the current running through the battery? (c) you add an additional resistor r3=7ω on the same branch as r2. what is the current running through the battery? (d) what is the power dissipated in r3?

Which is the most accurate name for the covalent compound p2o3?

Use the illustration to describe how the electromagnetic spectrum changes as its frequency moves from radio waves to higher energy gamma waves in terms of wavelength and amplitude.
