Answer:
Work = 92,704.5 joules
Power= 154.5 watts
Explanation:
Given that:
Time= 10 minutes
treadmill grade = 15% = 0.15
horizontal speed = 90 meters/min
subjects weight = 70 kg
To calculate the total work, we have;
work = force × distance
force = mass × acceleration
= 70 × 9.81
= 686.7N
Also, distance = speed × time × fractional treadmill grade
∴ distance = 90 meters/min × 10 min × 0.15 (treadmill grade)
Total work can therefore be calculated as:
work = force × distance
work = 686.7N × (90 meters/min × 10 min × 0.15 (treadmill grade) )
Work = 92,704.5 N/m
Work = 92,704.5 joules
To calculate the power, we have;
Power = workdone/time
Power = 92,704.5 joules/600 seconds
Power = 154.5 joules/second
Power= 154.5 watts

Answer:
the tide gets higher
Explanation:
during high tide, the gravitational pull of the moon raises the water in some places, a few feet, but in others, a few inches.
D. The scientists are most likely to find in there research is the immune system transforms the harm chemical in the contaminated food into a different form of chemical,which is then broken down and absorbed by the digestive system
<h3>
The correct answer is option A.
</h3>
According to octet rule, there is a tendency of the atoms to lose, share or gain electrons in order to complete their octet, the octet is the presence of 8 electron in the outermost shell. The sulphur has 6 valance electrons in its outer shell. The chlorine has 7 valance electrons in its outer shell. To complete the octet, the one chlorine atom shares 1 electron pair with the sulphur in SCl2.
