The answer is yes!
Hydrogen gas is generated as part of the charging process of lead/acid cell batteries. If the hydrogen gas acculates in large concentrations in a building or room or a box, an electrical spark or other ignition source will cause the hydrogen to burn in a rapid reaction causing an possible explosion.
A good example of a hydrogen gas explosion and fire is the "Hindenburg" disaster of the old flying blimps or zepplins.
Answer:
(A) We are using them faster than they are replenished by nature
Answer:
<h2>117.6 J</h2>
Explanation:
The gravitational potential energy of a body can be found by using the formula
GPE = mgh
where
m is the mass
h is the height
g is the acceleration due to gravity which is 9.8 m/s²
From the question we have
GPE = 6 × 9.8 × 2
We have the final answer as
<h3>117.6 J</h3>
Hope this helps you
Answer:
- The independent variable its A, the temperature.
Explanation:
There are two variable in this (mental) experiment. The temperature and the gender of the alligator.
The temperature its the independent variable, its the one we can control using the incubator.
The gender of the alligator, its hypothesized, will be determined by the temperature, so, its the dependent variable in our hypothesis.
The incubator will be used in all the eggs of the experiment, so, its not a variable.
The male alligators its one of the possible outcomes of the experiment. Again, not a variable.
It should be B!!!! Because you are suppose divide30km by 5 which is 6km/h.
