A 2.3 kg object has 15 ) of kinetic energy. Calculate its speed.
O A. 0.12 m/s
OB. 1.1 m/s
O c. 2.4 m/s
OD. 3.6 m/s
Answer:
The answer is option DExplanation:
To find the speed given the kinetic energy and mass we use the formula
[tex]v = \sqrt{ \frac{2KE}{m} } \\ [/tex]
where
m is the mass
v is the speed
From the question
KE = 15 J
m = 2.3 kg
We have
[tex]v = \sqrt{ \frac{2 \times 15}{2.3} } = \sqrt{ \frac{30}{2.3} } \\ = 3.61157559...[/tex]
We have the final answer as
3.6 m/sHope this helps you

Answer:
9.32×10⁻³
Explanation:
Scientific notation is the way to express the large value in short form.
The number in scientific notation have two parts.
. The digits (decimal point will place after first digit)
× 10 ( the power which put the decimal point where it should be)
How to add the number in scientific notation with same exponent.
7.21 ×10⁻³ + 2.11 ×10⁻³
exponent of both values are same thus we will take it common.
[7.21 + 2.11 ]×10⁻³
9.32×10⁻³

The mass of an atom Is found by adding Its protons and .The electric charge of an atom Is found by adding the charges carried by Its protons and .
Answer: the 1st answer is neutrons and i think the 2nd is nucleus
Explanation:
The mass of an atom is found by adding its protons and neutrons. The electric charge of an atom is found by adding the charges of its protons and electrons.
What is atomic mass?The atomic mass of an element is the total number of protons and the number of neutrons carried by one atom of that element. The atomic mass of an element is usually expressed in grams or a.m.u.
The atomic mass of an element = No. of protons + No. of neutrons
or
The atomic mass of an element = No. of electrons + No. of neutrons
The atomic number gives us information about how many protons are inside the nucleus of the atom. Elements are recognized by the number of protons in the nucleus. Neutrons are uncharged elementary or subatomic particles that are stable when bound in an atomic nucleus.
As the electrons and protons are charged particles in an atom, therefore, the sum of the charge carried by them is equal to the electrical charge of the atom.
For a neutral atom, the number of protons present in an atom is always equal to the number of electrons.

Why is this considered a theory instead of a hypothesis
or a law?
Answer/Explanation:
A theory has lots of scientific evidence to back it up. We know this to be true based on lots of different diseases and studies of their spread.
A hypothesis is more of a starting point - an educated guess based on limited evidence. It requires further testing before becoming a theory.
A law is something that can be generalized to lots of contexts, and is universal. Such as the law of thermodynamics.

1. Calculate the number of moles in each of the following masses:
a. 64.1 g of aluminum ans: 2.38 mol Al show work
Answer:
2.38 mol of Al
Explanation:
To find the number of moles in a substance, you simply divide by the atomic mass. In this case, the conversion table would look as follows:
[tex]\frac{64.1 g}{1}[/tex] * [tex]\frac{1 mol}{26.98 g}[/tex]
The gram units cancel, and you are left with the answer of about 2.38 moles of Aluminum.
