A boat is traveling at a velocity of 20 m/s North. The boat speeds up and is then traveling at 28 m/s North. If the boat took 4.5 seconds to speed up, what is the acceleration of the boat?

the electric field is a “force field” around a charged object that illustrates the direction the electric force would push an imaginary 

measuring things 1 litre of water

the best answer for these questions would be:

1.            c. is smaller

2.            d) concrete operational

3.            b) interaction with the environment – the children interact with their environment can them learn more.

4.            a) parents who reason openly with children can limit a child’s cognitive ability.

96.77 amp

explanation:

rl = 250/100 = 2.5 ohms.

egl = 250 + (100 × 0.1) + 2 = 262 v.

at 700 r.p.m., eg2 = 262 × 700/1000 = 183.4 v.

if ia is the new current, then eg2 - 2 - (ia × 0.1) = 2.5 ia

which means this will give ia = 96.77 amp.
