Answer:
They are in a periodic table
Answer:
alkali metals is your answer
Answer:
4.704J
Explanation:
The following data were obtained from the question:
m = 0.080kg
h = 6.0m
g = 9.8m/s^2
P.E =?
P.E = mgh
P.E = 0.08 x 9.8 x 6
P.E = 4.704J
Therefore, the potential energy of the robin is 4.704J
What occures is that the solution is know considered to be alkali, OH- ions react with the H+ ions from acids.
hope that helps :)
Answer : There are many ways to use electric current, but as you have asked for only three, here are some of them along with the change in their energy transformations;
1) Using a light bulb which consumes electrical energy and the energy is transformed into light energy, making everything visible for us.
2) Using a power tool makes use of electrical energy and the energy is transformed into mechanical energy for multipurpose use of cutting woods.
3)
Using electrical iron converts electrical energy into thermal energy to heat the iron and enables the user to iron crease-free clothes.
