Answer: d
Explanation: divide it by 4
Answer:
g ≈ 2.82 m/s^2
Explanation:
By W = mg,
W = weight (in newtons)
m = mass (in kg)
g = gravitational acceleration (in m/s^2)


g ≈ 2.82 m/s^2
Answer:
Hello! It should be 3.50m/s! Hope it helps.
Explanation:
Answer:
Ws=8.75 Watts
Explanation:
As per fig. of prob 02.061, it is clear that R5 and R4 are in parallel, its equivalent Resistance will be:



Now, this equivalent Req45 is in series with R3, therefore:

This Req345 is in parallel with R2, i.e

Now this gets in series with R1:

Now, the power delivered Ws is:

Refer to the diagram shown below.
h = original height of the pelican when the fish is dropped (not relevant).
S = distance traveled by the fish as a function of time, measured upward.
u = 0.5 m/s, the upward velocity with which the fish is dropped.
g = 9.8 m/s², the acceleration due to gravity.
Use the following equation:
S = ut + (1/2)gt²
S = (0.5 m/s)*(2.5 s) + 0.5*(-9.8 m/s²)*(2.5 s)²
= -29.375 m
The negative sign means that the fish drops by 29.375 m from the original height of h.
Answer: The fish is 29.375 m below where the pelican dropped it after 2.5 s.
