Answer:
12 units
Explanation:
Original F = C q1q2/r^2 now change the parameters
New F = C 1/3 q1 2 q2 / (2r)^2
= 2/12 C q1q2/r^2 <=======the new force is 1/6 of original
1/6 * 72 = 12 units
This information describes the storm's velocity.
Answer:
Loudness
Explanation:
In acoustics, loudness is the subjective perception of sound pressure.
Answer: 0.22
Explanation: Subtract 0.01kg from 0.23kg
Answer:
F = m a, a = 0.3 m / s²
this acceleration points in the direction of the unbalanced force
Explanation:
In this problem we must use Newton's second law. Let's fix a reference system with the x axis parallel to the surface and the y axis perpendicular
Y axis y
N-W = 0
N = W = mg
X axis
∑ F = m a
F = m a
we substitute
150 = m a
To find an acceleration value, the mass of the car must be known, if the mass is m = 500 kg
a = 150/500
a = 0.3 m / s²
this acceleration points in the direction of the unbalanced force
