It's False. Because it's electromagnet NOT circuit. I'd go with False if I were youSorry if you get it wrong. Hope this helps.
Let's see..

Answer: Elastic Potential Energy
Explanation: Energy present on compressed strings is called Elastic Potential Energy.
Th equations to be used here are the following:
a = (v - v₀)/t
x = v₀t + 0.5at²
The speed of the fugitive is the sum of his own speed plus the speed of the train. Thus,
v₀ = 0 + 5.5 m/s = 5.5 m/s
v = 8 m/s + 5.5 m/s = 13.5 m/s
a.) We use the first equation to determine time
2.5 m/s² = (13.5 m/s - 5.5 m/s)t
Solving for t,
t = 3.2 seconds
b.) We use the answer in a) and the 2nd equation:
x = (5.5 m/s)(3.2 s) + 0.5(2.5 m/s²)(3.2 s)²
x = 30.4 meters
Answer:
Option D. Weight varies with location, but mass does not.
Explanation:
To know which option is correct, it is important that we have a background knowledge of mass and weight.
A brief summary of the difference between mass and weight is given below:
1. Mass is the quantity of matter present in an object while weight is the gravitational pull on an object.
2. The SI unit of mass is kilogram Kg) while that of weight is Newton (N)
3. Mass is constant while weight varies by location.
4. Mass can measured using a chemical balance or beam balance while weight can be measured using a lever or spring balance.
With the above information, we can see that mass of an object is always but the weight varies by location.
