Answer:
Chemical energy transformations take place from the outlet charger to the ringing phone.
Explanation:
chemical energy
While charging the mobile electrical energy gets transformed into chemical energy. Most of the contemporary mobile phone batteries are lithium-ion batteries where the power is saved by the chemical transformations in the ionic structure of the battery. When the power gets into the mobile phone it is transformed and collected as chemical energy inside of the battery and when we utilize the mobile the earlier saved chemical energy is again transformed into electrical energy.
Magnitude of the force is the same as force so F=ma (mass x acceleration). The mass is 480 and you have to convert the acceleration to m/s so it’s 40km/h /3.6 = 11.1m/s. F= 480 x 11.1 therefore the magnitude of the force is 5,333.3... N
Answer:
680.6 N
Explanation:
The net force here is the resultant force. Taking that the two given forces act perpendicular to each other then the resultant is the hypotenuse. Therefore, where d is the magnitude of downward force and s is the magnitude of the sideways force. Substituting 631 N for downward force and 255 N for sideways force then
Therefore, the magnitude of net force is equivalent to 680. 6 N
