Carbon capture is the safest way to capture emission.
<u>Explanation:</u>
Emission of green house gases is one of the most lurking threat above humans. So one of the best ways to reduce emission is to capture the gases like carbon di-oxide or carbon monoxide, nitrous oxide etc. So mostly, the carbon di-oxide gas which is produced as waste is captured using adsorption, absorption, chemical looping etc.
In this method, they are captured from high source points like cement factory etc and then stored in a secluded region. Thus, the adsorption of these gases and then storing them in secluded region is the best option for capturing emission.
Answer:
2N
Explanation:
Given that a student pulls down with a force of 40 N on a rope that winds around a pulley of radius 5 cm. find the torque?
Solution
Using the formula
Torque = Force × radius
I.e
Torque = F r
Where
F = 40N
r = 5 cm = 5/100 = 0.05m
Substitute all the parameters into the formula
Torque = 40 × 0.05
Torque = 2 N
Therefore, the torque on this scenario is 2 N
Answer
given,
length of the track = 200 m
speed of runner 1 = 6.20 m/s
speed of the runner 2 = 5.5 m/s
distance covered by the fastest runner, d = 6.2 t
distance covered by the slow runner,d = 5.50 t + 200
time taken to overtake for the first time
6.2 t = 5.50 t + 200
0.7 t = 200
t = 285.7 s
distance covered from the starting point
d = 6.2 t
d = 6.2 x 285.7
d = 1771.43 m
for next overtaking time taken will be double
t' = 258.7 x 2 = 571.4 s
distance travel by the runner from the starting point
d' = 6.2 t'
d' = 6.2 x 571.4
d' = 3542.68 m
