The spring in a toy rocket launcher has a spring constant of 13 n/m. how far must you compress the spring to cause it to exert a force of 2.5 n?

Distance, x = 0.19 meters

Explanation:

It is given that,

Spring constant of the toy rocket, k = 13 N/m

Force applied on the spring, F = 2.5 N

We have to find the spring constant of the spring. It can be calculated using Hooke's law as :

F = - kx

x = 0.19 meters

Hence, the spring must be compress to cause it to exert a force of 2.5 N.

answer: option c. i.e. electric current flowing “downhill” from the negative electrode to the positive electrode in a battery

explanation:

the water analogy to the circuits define the pipes (water flows) to the electric current. now, we know that the electric current flows from the positive terminal to the circuit (as shown in the diagram attached).

hence, option c is the correct answer.

explanation:

wind is defined by the direction it blows from.   for example, a wind blowing from north to south is called a northerly wind.
