<span>The relationship between the electric field strength at a point and its distance from the source charge is inversely proportional. As the electric field strength increases the charges are more closer to each other which means the distance between the is smaller. It is seen by the equation:
E = </span><span>(1/4*pi*epsilon0) (Q/r^2)</span>
The energy of a wave is directly proportional to the square of the D.Amplitude
the energy of a wave is given as
E = (0.5) (μ v t ) w² A²
where t = time
μ = mass per unit length of the string
v = wave propagation of velocity.
w = angular frequency
A = amplitude
E = energy of wave
From the equation , we see that
the energy of wave "E" is directly proportional to A².
hence the correct choice is D. Amplitude.
Answer:
D)evaluating a solution
Explanation:
In this scenario, the next logical step would be evaluating a solution. This is because Jasper and Samantha have already identified the problem/need which is that the robot needs to be able to move a 10-gram weight at least 2 meters and turn in a circle. They also designed and implemented a solution because they have already built the robot. Therefore the only step missing is to evaluate and make sure that the robot they built is able to complete the requirements.
Answer:
it will take him 200secs to run to the shops
(btw 200 seconds is 3minutes and 20secs)
Explanation:
distance = speed x time
time = distance / speed
1200 ÷ 6 = 200
time = 200seconds
hope this helps
brainliest please?
