Answer:
is a field force, as gravity does not physically apply force and does not require proximity.
Explanation:
Answer:
The acorn hasn't hit the ground because it only falsl half of the branch distance from the ground
Explanation:
given information:
h =9.8
t =1 s
g = 9.8
the average speed
v = 1/2 gt²
= 1/2 (9.8) (1)²
= 4.8 m/s
the distance in 1s
h = v t
= 4.8 (1)
= 4.8 m
the acorn hasn't hit the ground because it only falsl half of the branch distance from the ground
=
A negative to a negative charge will make a neutral charge.
The absolute pressure is given by the equation,

Here,
is absolute pressure,
is atmospheric pressure and
is vacuum pressure.
Therefore,

The gage pressure is given by the equation,
.
Thus,
.
In kn/m^2,
The absolute pressure,

The gage pressure,
.
In lbf/in2
The absolute pressure,

The gage pressure,

In psi,
The absolute pressure,
.
The gage pressure,

In mm Hg
The absolute pressure,

The gage pressure,

Here we will the speed of seagull which is v = 9 m/s
this is the speed of seagull when there is no effect of wind on it
now in part a)
if effect of wind is in opposite direction then it travels 6 km in 20 min
so the average speed is given by the ratio of total distance and total time


now since effect of wind is in opposite direction then we can say



Part b)
now if bird travels in the same direction of wind then we will have


now we can find the time to go back



Part c)
Total time of round trip when wind is present


now when there is no wind total time is given by


So due to wind time will be more
