Henry plans to monitor the change in concentration of an acid during a chemical reaction. he wants to collect data every 01
seconds and then to graph his data and insert it into a text document
which pair of tools would be best for henry to use?
a computer and ph paper
ph paper and a graphing calculator
a computer and a concentration probe
a graphing calculator and a concentration probe
mark this and return
save and exit
tutoring

your answer would be fusion

uranium fissions/breaks up giving out energy and neutrons

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.

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j
