Answer:
Option B. 6.25 J/S
Explanation:
Data obtained from the question include:
t (time) = 2secs
F (force) = 50N
d (distance) = 0.25m
P (power) =?
The power can be obtained by using the formula P = workdone/time.
P = workdone / time
P = (50 x 0.25)/ 2
P = 6.25J/s
Insulin is produced by the pancreas because it allows sugar from the blood to enter cells and be ised for energy
Lifting is the correct answer
Answer: 1.2 seconds
Explanation:
Initial velocity =u=13.9m/s
Acceleration due to gravity=g=9.8m/s^2
Φ=25°
Time=t
T=(2 x u x sinΦ) ➗ g
T=(2 x 13.9 x sin25) ➗ 9.8
T=(2 x 13.9 x 0.4226) ➗ 9.8
T=11.75 ➗ 9.8
T=1.2 seconds
