Are you talking about a constructive force / constructive wave? Sorry I think that's what you are asking
Answer:
order of my age is 8 in seconds.
Explanation:
Suppose my age is 20 years.
Now, as we know that:
1 year has 365 days
1 day has 24 hours
1 hour has 60 minutes
1 minute has 60 seconds.
So my age in seconds will be:
Therefore the order of my age is 8 in seconds.
<span>Brass is an <u>alloy</u>. An alloy
is a mixture of elements to form a unique material. Brass is a mixture of copper
and zinc and the percentage of each element depends on the desired material. It
has a higher malleability than bronze or zinc. Meaning that it can be bend
easily into it desired form.</span>
Answer:
When we run a piece of paper with the oil in our head with the help of a comb produces electrostatic force.
Balloons get attracted to another balloon when one of them are rubbed with hair.
Explanation:
Those are 2 examples of electrostatic force.
Answer:
re = 2.09 Å.
Explanation:
As the electron is moving around the stationary proton along a circular path at a constant speed, there exists a force that keeps the electron within this trajectory, which is the centripetal force.
This centripetal force, is no other than the attractive electric force between the proton and the electron, so we can write the following equality:
Fe = Fc ⇒ k*Qp*Qe / re² = me*ve²/re
⇒ re = k*Qp*Qe / m*ve², where:
k = 9*10⁹ N, Qp =-Qe= 1.6*10⁻¹⁹ coul, me =9.1*10⁻³¹ kg, and ve= 1.1*10⁶m/s
⇒ re = 9*(1.6)²*10⁻²⁹ / 9.1*(1.1)²*10⁻¹⁹ m
⇒ re = 2.09*10⁻¹⁰ m = 2.09 Å.
