Answer: a = 200 Ω, b = 7.5 mA
Explanation:
Re = 100 + 100 = 200 Ω
I = E/R = 1.5/200 = 0.0075 A
Answer:
80 Meters.
Explanation:
What I did was took how many seconds the ball traveled and multiply how fast the ball was going. I actually do a lot of these questions. :))
May I please have brainlyest??
As we know that total work done by a force is given by
so it is product of force and displacement along same direction
as we can write it as
so it must be the product of force and displacement in same directions so correct answer must be
<u>B. in the same direction as the displacement vector and the motion.</u>
Answer:
1.75 s
11.4 m
Explanation:
In the y direction:
Given:
Δy = -15.0 m
v₀ = 0 m/s
a = -9.8 m/s²
Find: t
Δy = v₀ t + ½ at²
-15.0 m = (0 m/s) t + ½ (-9.8 m/s²) t²
t = 1.75 s
In the x direction:
Given:
t = 1.75 s
v₀ = 6.50 m/s
a = 0 m/s²
Find: Δx
Δx = v₀ t + ½ at²
Δx = (6.50 m/s) (1.75 s) + ½ (0 m/s²) (1.75 s)²
Δx = 11.4 m
