Answer:
These atomos are called isotopes.
Explanation:
Each chemical element is characterized by the number of protons in its nucleus, which is called the atomic number (Z).
The number of neutrons in the nucleus can vary. There are almost always as many or more neutrons than protons. The atomic mass (A) is obtained by adding the number of protons and neutrons in a given nucleus.
The same chemical element can be made up of different atoms, that is, their atomic numbers are the same, but the number of neutrons is different. These atoms are called isotopes of the element. That is, isotopes are atoms whose atomic nuclei have the same number of protons but different numbers of neutrons.
So, <u><em>these atomos are called isotopes.</em></u>
Answer:
Your mobile charger is an example of (d.) a generator.
Explanation:
Your mobile charger generates energy to charge your device.
Answer:
1/ 485.6 Nm
2/ Clock-wise
3/ 0 and no direction
4/ 1.62 m
Explanation:
1/ Torque is gravity force times the moment arm. Let's g = 9.81m/s2
2/ If person 2 is sitting on the right, the direction of this torque is clock-wise, since the gravity is acting downward.
3/ Assuming that location A is right at the pivot point, then the torque generated by this torque is 0, since the moment arm is 0. This has no direction.
4/ The seasaw is balanced, this means torques generated by 2 people are equal and in opposite direction
So the new location for d2 is 1.62m
Answer:
Explanation:
t=Time airborne=2.54 s
R= horizontal range= 25.5 m
From the projectile motion equations we know that:
H=7.9 m
