That's true: isotopes are chemical elements with same atomic number (i.e. same number of protons) but different mass number (i.e. different number of protons+neutrons, so if the number of protons is the same, the number of neutrons should be different).
For instance, hydrogen has three different isotopes:
- protium, with only one proton in the nucleus
- deuterium, with one proton and one neutron
- tritium, with one proton and two neutrons
Answer:
We will be effected not only with health, but also with our ability to carry out our genes to the next generation.
Explanation:
Our health is important, as we all know, so anything that happens to the digestive system will have a serious problem to our longevity, our reproductive system is also important to carry out our genes, and give birth to a new generation, it wouldn't effect us if only 1 person couldnt reproduce, but if everyone had a problem in their reproductive system, it would mean the extinction of all humanity.
The acceleration will be 10 m/s² if the force is doubled. Option C is correct.
<h2>What is Force?</h2>
It can be defined as the product of the mass of the object and its acceleration.
![F = m a](https://tex.z-dn.net/?f=F%20%3D%20m%20a%20)
Where,
- force = 45 N
- mass = ?
- acceleration = 5 m/s²
Now, put the values in the formula,
![45 = m \times 5 \\\\ m = \dfrac {45 }{5}\\\\ m = 9\rm \ kg ](https://tex.z-dn.net/?f=45%20%3D%20m%20%5Ctimes%205%20%5C%5C%5C%5C%0Am%20%3D%20%5Cdfrac%20%7B45%20%7D%7B5%7D%5C%5C%5C%5C%0Am%20%3D%209%5Crm%20%5C%20kg%0A)
Now if force doubled then the acceleration will be
![a = \dfrac {2 \times 45} {9}\\\\ a = 10 \rm \ m/s^2 ](https://tex.z-dn.net/?f=a%20%3D%20%5Cdfrac%20%7B2%20%5Ctimes%2045%7D%20%7B9%7D%5C%5C%5C%5C%0Aa%20%3D%2010%20%5Crm%20%5C%20m%2Fs%5E2%20%0A%0A%0A)
Therefore, the acceleration will be 10 m/s² if the force is doubled.

Answer:
T = 2490 newton
Explanation:
Given that,
Mass of a person, m = 50 Kg
Speed of the swing at the lowest point, v = 10 m/s
Length of the rope, r = 2.5 m
Tension formula is given by
T = mg + ma N
where, T - Tension in the string
m - mass of the body
g - acceleration due to gravity
a - acceleration of the body
Since the person is swinging, the acceleration of the body is given by
a = v²/r m/s²
= 10/2.5 m/s²
a = 40 m/s²
Substituting in T
T = 50 Kg x 9.8 m/s² + 50 Kg X 40 m/s²
= 490 + 2000 Kg m/s²
T = 2490 newton
Therefore the tension in the rope is 2490 newton
