Answer:
The peak electric field is
Explanation:
From the question we are told that
The power is
The cross-sectional area is
Generally the average intensity of the microwave is mathematically represented as
Where is the speed of light with value
and is the permitivity of free space with value
also is the peak electric field.
Now making the subject
But this intensity of the microwave can also be represented mathematically as
substituting values
]
So
Answer:
(a)
(b)
(c)x = 30m, y = 25m
(d)11.66m/s
Explanation:
While position has a formula of , velocity has a formula of a*t.
(a) the vector position of the particle at any time t is
(b) the vector velocity of the particle at any time t is
(c) at t = 5 s
So x = 30 m and y = 25m
(d)
with So the speed quantity is
Because regular wheels may get shot at and the tracks make it easier for the tank to go over rough/bumpy land.
According to James-Lange theory of emotion, a stimulus first leads to bodily arousal, and this is followed by our interpretation of it as an emotion.
