B acid rain in an area kills fish in a lake
We will use the formula / equation to determined the time.
Distance = ½ * (vi + vf) * t
48100 = ½ * (26.3 + 41.9) * t
t = 48100 ÷ 34.1 = 1410.557185 seconds
We will use the formula / equation to determined the acceleration.
vf = vi + a * t
41.9 = 26.3 + a * 1410.557185
a = (41.9 – 26.3) ÷ 1410.557185 = 0.011059459 m/s^2
We will use the formula / equation to determined the acceleration.
vf^2 = vi^2 + 2 * a * d
41.9^1 = 26.3^2 + 2 * a * 48100
a = (41.9^2 – 26.3^2) ÷ 96200 = 0. 011059459 m/s^2
Since both answers are the same, I believe the acceleration is correct.
Answer:
-2 C
Explanation:
charge of an electron = -
therefore charge of 1.25 x 
electrons = 
= -2 C
Answer:
a) The magnitude of the current is 24.19 A
b) The angle is 90°
Explanation:
a) Given:
B = magnetic field = 44 µT = 44x10⁻⁶T
r = distance = 11 cm = 0.11 m
The current is:
b) Because the current flows from the west to the east, therefore, the angle is 90 degrees from the north.
Density is the mass per unit volume of a substance and is simply the ratio of mass to volume. Unlike mass, density is a characteristic property of a material, meaning a property that has the same value for any size sample of a given substance.
Hope this helps:)
