Explanation:
Nutrient deficiency causes yellowing of leaves. One of such nutrient is Nitrogen.
- Leaves are green because of a pigment in them called chlorophyll.
- The chlorophyll in leaves are used by plant to absorb light energy needed for photosynthesis.
- Other wavelength of light is absorbed by the chlorophyll and the green color is reflected.
- Nitrogen is an important nutrient that is needed to produce chlorophyll in plants which in turn helps the process of photosynthesis.

Answer:
9.57m/s²
Explanation:
Given parameters:
Initial velocity = 0m/s
Final velocity = 90m/s
Distance = 423m
Unknown:
Acceleration of the race car = ?
Solution:
To solve this problem, we should apply one of the appropriate motion equations;
V² = U² + 2as
Where V is the final velocity
U is the initial velocity
a is the acceleration
s is the distance
90² = 0² + 2 x a x 423
8100 = 846a
a = 9.57m/s²
Givens
Total Resistance (the bulbs are connected in series)
- R = r1 + r2
- r1 = 3 ohms
- r2 = 3 ohms
- R = 3 + 3 = 6 ohms
- E = 12 volts
- I = ??
Formula
E = I * R
Solution
12 = I * 6 Divide both sides by 6
12/6 = I*6/6
2 = I
The current = 2 amperes. Answer
The answer is, "A", "Formerly known as Byzantium".
Answer:
17.5 Newtons
Explanation:
Force = mass x acceleration
Mass = 7kg
Acceleration = 2.5ms^-2
Therefore , force f = 7 x 2.5
= 17.5 Newtons
