Answer:
Explanation:
Given:
radius of capillary, 
angle of contact, 
density of water, 
surface tension of water, 
height, h = ?
We have the equation for the height of meniscus as:
No, the capillary action alone cannot be the mechanism of water transportation to the top of the trees. Transpiration also creates a suction pressure in the xylem complementary to the ascent of sap and cohesion of water being the other causes of movement of water up in the plants.
The magnetic force on a charged particle is given as: F = qvBsinФ
B is the magnetic field.
q is the charge on the particle.
v is the velocity of the charged particle.
Ф is the angle between magnetic field (B) & the velocity of charge (v).
⇒ F = qvb sin Ф
Here, Ф = 90 degree.
and sin 90 = 1
Putting the values in the equation, we get,
F = 1.6 x 10^-19 C × 4.5 × 10^7 m/s × 1.6 T
= 11.52 × 10^-12N
= 1.2 x 10^-11 N up
Answer:
Q1: (a)
so
Q2:
this is the radius in meter
diameter = 2r
in this i don't know which choice is the right answer
Q3:
so
again there is no correct answer
Answer:Specific heat is the amount of heat required to raise one gram of any substance one degree Celsius or Kelvin. The formula for specific heat is the amount of heat absorbed or released = mass x specific heat x change in temperature.

Answer:
Explanation:
1)Sunlight is a limiting factor because it helps the plants grow.
2) plants and trees give u oxygen so that u can breathe
3) plants and trees are habitats for some animals.
Increased nitrogen can increase the growth of algae which is a benefit of it
