Answer:
The leaf cells would be unable to convert the sun's energy to make food.
Explanation:
The chloroplast in the leaf are used to make food for the plant. If the leaf loses its chloroplast, the leaf with not be able to use solar energy to manufacture their food.
- During photosynthesis, green plants manufacture their food.
- They use sunlight to cause a reaction between carbon dioxide and water.
- The sunlight is trapped using chlorophyll present in the leaf.
- In the absence of the chlorophyll contained in the chloroplast, no solar energy would be generated to cause the reaction to take place.
You could increase the mechanical efficiency of this screw by reducing friction along the screw threads
Answer:
I guess the answer is charging by friction
Answer:
D
Explanation:
5 Km=5000m
so Δv=5000 m/sec
a=Δv/Δt
=5000/10
a=500 m/sec² as 500÷1000=0.5 Km
a=0.5 km/sec²
so D is the right answer.
Answer:
3.65 x mass
Explanation:
Given parameters:
Time = 20s
Initial velocity = 0m/s
Final velocity = 73m/s
Unknown:
Force the ball experience = ?
Solution:
To solve this problem, we apply the equation from newton's second law of motion:
F = m 
m is the mass
v is the final velocity
u is the initial velocity
t is the time taken
So;
F = m (
) = 3.65 x mass
