Answer:
The force exerted by the child is 38.25 Newton
Explanation:
We use the formula F=mxa (m=mass and a= aceleration):
F= 45kg x 0,85 m/s2=38, 25 kgxm/s2= <em>38, 25 N</em>
The answer is B) increase, increase
You can work this out mathematically with the equation PV = nRT.
Because volume is halved, the pressure will double, which increases rate of reactions as well.
Wrap the wire around the nail. the more wire you wrap around the nail the stronger your electromagnetic will be. make sure you leave enough wire so you can attach the battery. also when you wrap the wires around the nail make sure that you wrap the wires all in one direction ( i learned this in elementary)
