Lighting a match
hope the answer helped!
Assume the downward direction is positive and upward direction is negative
W = weight of the object = 12 N
f = air resistance on the object = - 3 N
F = net force on the object
net force is the sum of forces acting on the object , hence the net forces is given as
net force = sum of forces
F = W + f
F = 12 + (- 3)
F = 12 - 3
F = 9 N
hence the size of net force on the object comes out to be 9 N
Answer:
C
Explanation:
WIPP was formed for storage and disposal of the nation's transranic radioactive waste.
Given that,
s = √(2t + 1)
Time, t = 4 s
Acceleration , a = ??
Since,
Acceleration = velocity / time
Velocity = distance/ time
Acceleration = distance/ time²
s/t² = √(2t+1)/t²
putting t = 4 sec, we have
a = √(2*4+1)/4²
a = √(5)/16
a= 0.139 ft/s²
Therefore, acceleration of the given particle will be 0.139 feet/ second².
it absorbs energy and releases oxygen and glucose.
