1. They have evolved their leaves into spikes for minimum water loss through transpiration.
2. They have a waxy layer for minimum water loss.
3. They have thick walls for minimum water loss.
4. They can take water from atmosphere.
5. They change the photo energy from Sun into an intermediate stage and store it, so that they can make food even in night.
Answer: The correct answer is A.
Explanation:
To avoid over driving your headlights, cool your headlights periodically by switching to your parking lights.
It is difficult to stop in the distance you see ahead of you at night without using headlights. Otherwise, there may be chances of occurring an accident.
Avoid to use the high beams is used whenever you drive at night. Suppose, if the car is coming in front of your car then in this case the drivers to have a flash blindness. As he gets bright light in his eyes. Otherwise, there may be chances of occurring an accident.
Therefore, to avoid over driving your headlights, cool your headlights periodically by switching to your parking lights.
All living things are made up of one out more cells is correct.
Answer:
26.82m/s
Explanation:
Given
Mass = m= 0.4kg
Initial Velocity = u = 0
Charge = 4.0E-5C
Distance= d = 0.5m
Object Charge = 2E-4C
First, we'll calculate the initial energy (E)
E = Potential Energy
PE = kQq / d
Where k = coulomb constant = 8.99E9Nm²/C²
Energy is then calculated by;
PE = 8.99E9 * 4E-5 * 2E-4 / 0.5
PE = 143.84J
Energy = Potential Energy = Kinetic Energy
K.E = ½mv² = 143.84J
½mv² = ½ * 0.40 * v² = 143.85
0.2v² = 143.85
v² = 143.85/0.2
v² = 719.25
v = √719.25
v = 26.81883666380777
v = 26.82m/s
Hence, the object is 26.82m/s fast when the cart moving is very far (infinity) from the fixed charge
