Answer:True
Explanation:
Albedo is a unit-less, non-dimensional quantity that shows how well a surface reflects solar energy. The value of albedo can vary from 0 to 1, 0 being the black and 1 refers to a white surface. Zero means Surface is a perfect absorber i.e. it absorbs all the incoming rays incidents on it. Albedo 1 means the surface is a perfect reflector.
Albedo usually applies for visible light, even though it may involve some of the infrared regions of the electromagnetic spectrum. The average albedo associated with earth surface is 30%
A. The water
Biotic factors mean living this such as frogs, grasshoppers, snakes, etc.
Aboriginal factors means non-living such as water, temperature, sunlight, etc.
Abiotic factors are the non-living parts of the environment that have a major influence on living organisms which makes water an abiotic factor.
Hope this helped, if it did please like (if you want to :)
We know, I = Q / t
Here, Q = 150 C
t = 30 s
Substitute their values,
I = 150 / 30
I = 5 A
In short, Your Answer would be 5 Ampere
Hope this helps!
10.3
Explanation:
Step 1:
The pressure exerted by any liquid column of height, h density d is given by the formula P = h * d * g
Step 2:
It is given that one atmosphere pressure pushes up 76.0 cm of mercury, we need to calculate the level of water that will be pushed by the same pressure.
Step 3:
Since the pressure pushing up mercury and water is the same
* 
* g = 
* 
* g
= 
= (13.6 g/cm * 76 cm)/1 g/cm = 1033.6 cm
Step 4:
Now we need to express the answer in meters.
1 m = 100 cm.
1033.6 cm = 10.336 m
This can be rounded off to 10.3 m
Answer:
It will travel 45 km (45000 m)
Explanation:
25 minutes is equal to 1500 seconds (25*60=1500)
distance=speed*time
distance=30m/s * 1500s = 45000 m = 45 km
