7. Why is transpiration important for plants?

Physics
1 answer:
jasenka [17]2 years ago
7 0

Answer: The rate at which water moves through the plants due to transpiration plays an important role in maintaining plant water balance. ... This moves water and other nutrients absorbed by roots to the shoots and other parts of the plant. Hence, transpiration is very important for the survival and productivity of plants.

Explanation: the explanation of the answers is that Advantages of a dry cell are:

The compact size of a dry cell makes it suitable for powering small electronic devices.(toys, flashlights, portable radios, cameras, hearing aids). The electrolyte used in dry cell is relatively not so harmful to the environment. Dry cells are inexpensive. The main disadvantage of a dry cell is that it cannot be recharged once it loses its electrical power, Because when the cells turn any color then you are died.

If something is hot, does it contain heat or thermal energy?
zysi [14]
I am absolutely sure that if something is hot,  it contain thermal energy only because <span>if a given body is heated its electrons start to move very fast which means that thermal energy is being produced. Hope everything is clear! Regards!</span>

if the car went 30 km west in 25 min. and then 40 km south in 35 min., what would be its average speed?
igomit [66]
Average speed  =  (distance covered) / (time to cover the distance)

                           =  (30km + 40 km)  /  (25min + 35min)

                           =        (70 km)  /  (60 min)

                           =             70 km/hour

n astronaut who weighs 800 N on the surface of the earth lifts off from planet Zuton in a space ship. The free-fall acceleration
ANTONII [103]

Answer: 0.29 kN

Explanation:

We have the following data:

W_{E}=800 N is the weight of the astronaut on Earth

g_{E}=9.8 m/s^{2} is the free fall acceleration due gravity on Earth (directed downwards)

g_{Z}=3 m/s^{2} is the free fall acceleration due gravity on Zuton (directed downwards)

a=0.5 m/s^{2} is the acceleration of the spaceship at litoff (directed upwards)

We have to find the <u>magnitude of the force</u> F the space ship exerts on the astronaut.

Firstly, we have to know weight has a direct relation with the mass and the acceleration due gravity. In the case of Earth is:

W_{E}=mg_{E} (1)

Where m is the mass of the atronaut.

Isolating m:

m=\frac{W_{E}}{g_{E}} (2)

m=\frac{800 N}{9.8 m/s^{2}} (3)

m=81.63 kg (4)

Now that we know the mass of the astronaut, we can find its weight on Zuton:

W_{Z}=mg_{Z} (5)

W_{Z}=(81.63 kg)(3 m/s^{2}) (6)

W_{Z}=244.89 N (7)

Then, we can calculate the force the space ship exerts on the astronaut by the following equation:

F-W_{Z}=m.a (8)

Isolating F:

F=m.a+W_{Z} (9)

F=(81.63 kg)(0.5 m/s^{2})+244.89 N (10)

F=285.7 N \frac{1 kN}{1000 N}=0.285 kN (11)

Finally:

F=0.285 kN \approx 0.29 kN
