I = V/R = 120 V/ 10 Ohm = 12 A
Answer:
Let's say the pitcher is angry or just has a really heavy hand while throwing this ball, and now you have to catch it, otherwise it's going to ram into your face. When you put your hands up just in time to catch this ball, this is called impulse, or commonly expressed as a reflex. Depending on what kind of ball is being thrown, such as a golf ball, baseball, basketball, beach-ball, rubber-ball, baseball, etc. ... the weight of the ball itself is going to impact how much it i going to hurt when you catch it without any hand protection. However, if you're catching, let's say a baseball, with a padded glove, it is not going to hurt as bad as catching the baseball bare handed, because the padded glove has enough padding in it to create a barrier between the skin of your hand and the palm of the glove.
The third bar, which we can call the test bar, is known to be a magnet, so it has a north pole and a south pole. Bring one end of each of the two unknowns near the magnet. That unknown bar which is a permanent magnet will be attracted to the test bar when opposite poles are brought together, but it will be repelled from the test bar when like poles are brought together. Both ends of the unknown bar which is a ferromagnetic bar, will be attracted to the test bar. The magnetic field of the test bar will always induce a pole that is opposite in polarity to the pole of the magnet. Ferromagnetism always results in attraction. Hope this helps a lot :)
Answer:
The mass defect Δm = 0.33626 amu
Explanation:
Given,
The actual mass of a Cl 37 atom, m = 36.966 amu
The atomic number of Cl is 17. Hence, chlorine has <em>17 protons</em>,
Therefore, the Cl 37 has <em>20 neutrons</em>
The mass of 1 proton = 1.00728 amu
The mass of 1 neutron = 1.00867 amu
The mass of 17 protons = 17 x 1.00728 = 17.12886 amu
The mass of 20 protons = 20 x 1.00867 = 20.1734 amu
The total mass of proton and neutron, M = 37.30226 amu
The mass defect is defined as the difference in the sum of the mass of protons and neutrons of the nucleus of an atom to the actual mass of the nucleus.
Therefore,
Δm = M - m
= 37.30226 - 36.966
= 0.33626 amu
Hence, the mass defect of the Cl 37 atom is, Δm = 0.33626 amu
