What is the electric force acting between two charges of -0.0085 C and
-0.0025 C that are 0.0020 m apart?
Use F. = 6992 and k =9.00 x 10° Nm?/C?.
O A. -9.6 x 10'N
O B. 9.6 x 107N
O C. 4.8 x 1010N
O D. -4.8 x 1010 N

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.

The radiation of the fire causes the saucepan to heat up. the conduction of the saucepan then to distribute the heat over the saucepan and to give heat to the water. the convection of the water distributing the heat within the water, till all the water is boiling
