Answer:
Push because the force you use up is greater then down
Answer:
2500 Newtons
Explanation:
If force equals the mass × acceleration then all should be quite simple
25kg is the mass of your car
100 m/s/s is the acceleration of you car
25kg • 100m/s/s = 2500 Newtons
Science based on properties of matter and energy
Answer:
The 50-W bulb glows more brightly than the 100-W bulb
Explanation:
The bulb has a rating of 100 W under 110 V . So it will glow with full brightness when it is fed 110 V . When bulbs are in parallel combination , each bulb receives 110 V . So they glow with full brightness .
When they are in series combination , 110 supply voltage gets distributed between the , thus , reducing the voltage appearing on each of them less than 110 V . So their brightness is reduced.
resistance = V
Bulb having high wattage rating has low resistance resulting in higher current . In the second case , both have same current as they are in series combination . So more heat will be generated in bulb having more resistance . Since 50 W bulb has higher resistance , it will glow brighter than 100 W bulb.
