An Isotope has the same number of Protons but a different number of neutrons than other atoms of the same element.
In short, an isotope has the same atomic number, but a different molar mass.
Answer:
Explanation:
Near the earth's surface where gravity is approximately 10 m/s² downward
v = u + at
v = 5 + (-10)(1) = -5 m/s
so it has the same speed but in the opposite (downward) direction.
Answer:
10 m/s²
Explanation:
Force is the product of mass of an object and its acceleration
The formula is : F= m*a -----where m is mass and a is acceleration
Use the values given in the equation as;
F= m*a
1000 = 100 * a
1000/100 = a
10 = a
10 m/s² = a
Answer:
The signal will move down by 1 division
Explanation:
We have two signals here:
- An AC signal (sine wave), centered at 0 V, with amplitude 2 V (it means that it goes from a maximum of +2 V to a minimum of -2 V)
- A DC signal, which appears in the oscilloscope as a flat line, of 1 V
If we add these two signals together, we are adding a constant offset of +1 V to the sine wave, so the sine wave will move up by one division
Now, if we readjust the position so the trace is centered again at 0 V, we are moving the signal down by 1 division
Then, if we switch the signal in channel B from DC to AC, we are removing the constant offset of 1 V - so the signal will be now centered at -1 V. Therefore, the signal will move down by 1 division.
Part A: a->positive when velocity is increasing a->negative when velocity is decreasing a->zero when velocity is constant
