In order to form a real image using a concave mirror, the object must be placed beyond the center of curvature of the mirror. Therefore, the object must be further from the mirror than the focal point. The image that will form will be real, but it will also be inverted and its magnification will be less than 1, meaning it will be smaller than the actual object.
Answer:

Explanation:
Given that,
Initial velocity, u = -5 m/s
Final velocity, v = -22 m/s
Time, t = 3s
We need to find the acceleration of the car. The formula of it is given by :
Acceleration,

So, the acceleration of the car is
.
Hi! I'm a few days late since I just saw this question just now, but I'll answer anyway.
Answer:
When an unbalanced force acts on a moving object, the velocity of the object will change. Change in velocity means a change in speed, direction, or both. For example, if you kick a soccer ball and it moves from one place to another, it means that unbalanced forces are acting upon it. The ball moves from one place to another after kicking it so the position changed.
I honestly think it is B, if not I'm sorry for the incorrect answer, but B seems to be the only one to make sense
Answer:
The answer is + 4.8V
Explanation:
The electric potential is
V = k ∑ 
We apply this expression to our case with three charges
V = k (q₁ / r₁ + q₂ / r₂ + q₃ / r₃)
The distance is
R = √((x-x₀)² + (y-y₀)²+ (z-z₀)²)
Let's find the distances
q₁ = 50 10⁻⁹ C
r₁ = √ ((8-0)² + (0-6)²)
r₁ = 10m
q₂ = -80 10⁻⁹ C
r₂ = √ ((8 + 4)²
r₂ = 12m
q₃ = 70 10⁻⁹ C
r₃ = √ ((8-0)²+ (0 + 6)²)
r₃ = 10 m
We calculate the potential
V = 8.99 10⁸ 10⁻⁹ (50/10 -80/12 +70/10)
V = 4.795 V
The answer is + 4.8V
