Biology
1 answer:
Andreyy893 years ago
3 0

Answer:

0.3 m/s^2 is Bob's  average acceleration.

Explanation:

Initial velocity of the bob's in-lineskates= u = 0 m/s

Acceleration of the Bob= a  = ?

Final velocity of the bob's in-lineskates= v = 4.5 m/s

Duration of time in which 0 m/s velocity is changed to 4.5 m/s = t = 15 s

Using first equation of motion: v = u + at

4.5 m/s=0m/s+a\times (15 s)

5.0 m/s-0m/s =a\times 15 s

4.5 m/s=a\times 15 s

a=\frac{4.5 m/s}{15 s}=0.3 m/s^2

0.3 m/s^2 is Bob's  average acceleration.

Lotions applied during winter season moisturize the skin very quickly. What could be the reason for this?
MrRissso [65]

The right answer is D.

The absorption of molecules at the level of the skin is carried out by passive diffusion for the molecules of low molecular weight (lower than 400 Da), the skin being covered with a lipoprotein film rich in water by its stratum corneum, rendering it little-permeable.

This absorption may be variable according to factors related to the skin such as stratum corneum's thickness, the state of hydration, the presence of cutaneous lesions or individual variations.

External factors may also modulate percutaneous absorption such as contact time, iontophoresis or the presence of specific adjuvants.

The diagram shows some of the steps in the flow of energy through an ecosystem. The arrows represent the transfer of energy. Lab
Feliz [49]

The given diagram is food chain. Food chain is a sequence of populations or organisms of an ecosystem through which the food and its contained energy passes with each member becoming the food of a later membre of the sequence. The number of trophic levels in a food chain is 3-6 and in each trophic level a lot of biomass is consumed in liberating energy.

In the above food chain plants( producers) radiant light energy into chemical form. Rodents are primary consumer, owl is a secondary consumers or primary carnivores and wolf is a tertiary consumer or secondary carnivores.

Which tool enhances weather forecasts by enabling monitoring, which is necessary for predicting global weather and environmental
kotegsom [21]

The correct answer is - satellite.

The satellites are something that is crucial for the functioning of the modern day world in pretty much all aspects. They are also very important in the climatology and meteorology. The satellites are able to monitor the whole planet, thus through them it can easily be seen where the air masses are moving, what type of air masses are moving towards where, their speed of the air masses, is there clouds, and if there is where are they moving, formation of large storms etc. ll of these information from the monitoring of the satellites go to the weather stations, where the weather forecasts are made, and than through the media reach the people all over the world.
