Answer:
option C
Explanation:
Capillary action is important because it's necessary thing in plants food and oxygen productionIt is done through capillary tubes of diameter 0.1mm and the water rises up high in the trees.So option C is correct

What is the mass of an object that accelerated at 5 m/s2 with a force of 45 n?
Answers
Answer:
9kg.
Explanation:
Data obtained from the question include:
F (force) = 45N
a (acceleration) = 5 m/s2
m (mass) =?
Force is simply the product of mass and acceleration as given by the formula: F = ma. With this formula (i.e F = ma) we can easily calculate the mass of the object. This is illustrated below:
F = ma
m = F/a
m = 45/5
m = 9kg.
Therefore, the mass of the object is 9kg
Which components of static electricity does a photocopier use?
ex. charging by conduction, friction, etc
Answers
Answer:
For a photocopier to work, a field of positive charges must be generated on the surface of both the drum and the copy paper. These tasks are accomplished by the corona wires. These wires are subjected to a high voltage, which they subsequently transfer to the drum and paper in the form of static electricity.

Here, the velocity goes from 0 to 34 m/s in 0.0116 s. The mass is 0.058 kg. Filling in the given values, we have ...
F(0.0116 s) = (0.058 kg)(34 m/s)
F = 0.058×34/0.0116 kg·m/s² ≈ 170 N
The required force is 170 newtons.

How energy efficiency can reduce energy consumption?
Answers
Answer:
The energy efficiency represents the things you can do with some amount of energy, and if you can do more with less, than it reduces the energy consumption.
Explanation:
The answer to this question is actually very simple. Imagine that you use only the half of the energy you produce, an efficiency of 50%. Lets say you need 5kJ, so you would need to produce 10kJ, because you can consume only the half. Now, imagine you increase the efficiency, you use exactly what you can generate, (efficiency of 100%). In this case, if you needed only 5kJ you would need to generate only 5kJ.
explain the causes of atmospheric pressure and why it changes with altitude?
Answers
Answer:
As altitude increases, the amount of gas molecules in the air decreases—the air becomes less dense than air nearer to sea level. This is what meteorologists and mountaineers mean by "thin air." Thin air exerts less pressure than air at a lower altitude

a racing car has a uniform acceleration of 5 metre per second square what distance will it cover in 10 seconds after the start
will mark as brainlist
Answers
Given ,
Acceleration, a = 5 m/s^2
time , t = 10 seconds
Initial velocity,u = 0
Final velocity , v = ?
We have ,
v = u + at
=> v = (0)+(5)(10)
=> v = 50 m/s
So you have to rearrange the equation to find distance.
Distance = time * speed
So distance= 5*10
Distance = 50 metres

A block and a ball have the same inertia and move with the same initial velocity across a floor and then encounter different ramps. The ramps are identical in every way except for the fact that there is enough friction for the ball to roll without slipping and the block slides without friction up the ramp. Which one makes it furthest up the ramp
Answers
The ball rolling without slipping will make it furthest up the ramp because it has greater kinetic energy.
Conservation of energy
The height rolled by each object can be determined by applying the principle of conservation of energy.
The ball rolling without slipping will have additional rotational kinetic energy.
The block won't have additional rotational kinetic energy.
Total K.E ball > Total K.K block
ΔP.E = ΔK.E
Thus, the ball rolling without slipping will make it furthest up the ramp because it has greater kinetic energy.

Answers
Answer:
KE = F * S initial kinetic energy will expended in stopping object
1/2 M V^2 = F * S
S = 1/2 * 50 * 35^2 / 800 = 38.3 m stopping distance
If you need to know the stopping time involved -
(V2 - V1) = a t where the change in velocity is 35 m/s
a = F / M = 800 / 50 = 16 m/s^2 deceleration of mass
t = 35 / 16 = 2.2 sec
