The third launch ( with 300 N force) had the greatest acceleration of the tennis ball
<h3>Further explanation </h3>
Newton's 2nd law explains that the acceleration produced by the resultant force on an object is proportional and in line with the resultant force and inversely proportional to the mass of the object
∑F = m. a
F = force, N
m = mass = kg
a = acceleration due to gravity, m / s²
From the above equation it has been shown that the force acting on the object is directly proportional to its acceleration, so <em>the greater the force exerted on the object, the greater the acceleration of the object produced.</em>
Answer:
Lithium has 3 protons, 4 neutrons, 3 electrons, and its mass is 6.941 u
Answer:
I believe the answer would be D
Explanation:
The reason why is that I divided 5.75 with 5 which results in 1.15
Answer:
+4
Explanation:
Hello,
In this case, considering nitrogen dioxide's formula:
And due to the fact that oxygen's oxidation state is -2 in this case, we could find nitrogen's oxidation state in nitrogen dioxide by using a balance charge:
For that reason, nitrogen's oxidation state is +4:
Best regards.
Answer:
c) hydrogen bonding.
Explanation:
Like water molecules which are H2O, hydrogen disulfide also has a bent shape. However, unlike water, it cannot have hydrogen bonding. Why? Because hydrogen bonding only occurs with nitrogen, oxygen, and fluorine. I haven't heard of disulfide linkages. And yes, H2S has London dipersion forces. All polar molecules have LDFs. But greater than that, H2S has dipole-dipole forces. Event though it is a dipole-dipole bond, it is still highly electronegative.
