Here, Force = m * a = 34 * 2 = 68 N
According to Newton's third law, fence will exert equal and opposite force (by direction) on the robot.
In short, Your Answer would be Option C) <span>The robot exerts a force of 68 N on the fence; the fence exerts a force of 68 N on the robot.
Hope this helps!</span>
The diameter of the moon is about 2,161 miles or (3,476 kilometers).that makes the circumference about 6,790 miles
Answer:

Explanation:
on the specific planet ,
weight =400 N acts downwards
astronaut gives an upward force of 462 N
according to the Newton's second law of motion ,
applying Force= mass * acceleration upwards
462 - 400 =5 * a
acceleration =
Answer:
99
Explanation:
First strike=25 in
Second strike=4/5*25=20 in
Third strike=4/5*20=16 in
Fourth strike=4/5*16=12.8 in
Fifth strike=4/5*12.8=10.24 in
sixth strike=4/5*10.24=8.192 in
seventh strike=4/5*8.192=6.5536 in
Total=(25+20+16+12.8+10.24+8.192+6.5536) in=98.7856 in
Taking this as a geometric series
where a is initial value taken as 25 for this case and r is rate taken as 4/5 or 0.8 in our case

To the nearest inches, sum is 99 in
