FORMULA:
ANSWER:
We are given with mass of truck 95kg and K.E. truck 150,000J.
Plugging the respective value, by assuming velocity = v:
- 150,000 = 1/2 × 95 × v²
- 150,000 × 2/95 = v²
- 3157.89 = v²
- √3157.89 = v
- 56.19m/s = v
Answer:
4
Explanation:
because amplitude of a sound wave is related to loudness of the sound, so the higher the amplitude, the louder the sound

Answer:
y = 10.2 m
Explanation:
It is given that,
Charge, 
It is placed at a distance of 9 cm at x axis
Charge, 
It is placed at a distance of 16 cm at x axis
We need to find the point on the y-axis where the electric potential zero. The net potential on y-axis is equal to 0. So,
Here,
So,
Squaring both sides,
So, at a distance of 10.2 m on the y axis the electric potential equals 0.
We have that the most stable nuclei are the ones with the highest average binding energy. We see that Nitrogen has a mass number of 15 and that in this region of the graph average binding energy is low. Silver and Gold are along a line where there is a constant decline in average binding energy; silver has more than gold. However, we see that at the start of this decline, there is Fe 56. This region has the elements with the highest average binding energy; Nickel with a mass number of 58 is right there and thus it is the most stable nucleus out of the listed ones.
