If we want to tip 19% or 0.19 of a bill of $26.37
We just multiply 26.37*0.19=$5.01
Any questions please feel free to ask. Thanks
Answer:
THERMAL IMAGING
We can sense some infrared energy as heat. Some objects are so hot they also emit visible light—such as a fire does. Other objects, such as humans, are not as hot and only emit only infrared waves.
Newton's third law states that if a force is exerted on an object, the object exerts a force<span> back.

Answer:
have the same number of protons
Explanation:
Atoms of the same element will always have the same number of protons.
Protons are the positively charged particles in an atom which are located in the nucleus.
- To recognize an atom, the number of protons is used.
- The number of protons is the atomic number.
- On the periodic table, atoms are arranged based on the number of protons.
The answer for this question would be B. Both elements, one being a Group 1 and the other being a Group 17, want to attain the octet of electrons in the outermost shell for chemical stability. The Group 1 element has one too many electrons, and the 17 is lacking one. To increase the stability of the system, the Group 1 can donate the extra electron to the Group 17 so that both can emulate a stable octet. In doing so, two ions are produced (elements that have a net charge that isn’t 0), and thus we have an “ionic bond.”
Hope this helps!
