Answer:
It’s called a conservative field.
Explanation:
I think it’s going to be the conservative field because in the question it talks about how it is able to become possible to define potential at a point in an electric field because electric field.
Answer:
a)
b)
Explanation:
Given that
Initial velocity u =0 m/s
Speed at 5 s v= 282 m/s
Rocket accelerated up to 5 s :
We know that
v= u + at
282= 0+ a x 5
So the acceleration
Rocket come to rest in 1.4 s :
Final velocity of rocket v=0 m/s
Initial velocity = 282 m/s
v= u + at
0= 282 - a x 1.4
So the deceleration
Answer:
the separation of the interference maxima is directly proportional to the wavelength
the greatest separation must be obtained for the red light of
λ = 700
Explanation:
The double slit interference experiment is explained for the constructive interference case by the expression
d sin θ = m λ
where d is the separation between the slits, θ at the angle of separation of the different maxima, λ the wavelength and m the order of interference.
In these experiments the angles are always very small, so if the observation screen is at a large distance and y is the distance between the maximums, we can use trigonometry
tan θ = y / L
as the angle is small we can also use
tan θ = sin θ / cos θ = sin θ
when substituting we find
sin θ = y / L
the contributory interference equation remains
d y / L = m λ
y = m (L / d) λ
the quantity in parentheses is constant, so the variation in the separation of the interference maxima is directly proportional to the wavelength
by which the greatest separation must be obtained for the red light of
λ = 700
answer:
The horizontal component of the 600 N force is,
Fx = 600 cos(30) 519.61 N
The vertical component of the 600 N force is,
Fy = 600 sin(30) = 300 N
