Answer:
Conduction is the transfer of heat energy by direct process.
Radiation is the transfer of heat energy with electromagnetic waves
Explanation:
Answer: This is an example of downregulation and upregulation.
Explanation:
Downregulation is a process in which cells decrease the production of one of their components, responding to an external stimulus. Upregulation, on the other hand, is when cells increase the production of one of their components in response to an external stimulus.
In this case, the decrease in insulin receptors would make the cell less sensitive to the hormone.
If there's a lot of insulin around those cells, the cell would have to decrease its sensitivity, otherwise, it would metabolise more glucose than the body needs. The contrary would happen if there was too little insulin around those cells, they would have to become more sensitive to it by increasing the number of receptors.
Answer:
Δy = v₀t + (1/2)gt²
where g = 9.81 m/s if the body is moving downwards and g = -9.81 m/s if the body is moving upwards
Explanation:
The general kinematic equation for horizontal displacement is gives as:
Δx = v₀t + (1/2)at²
Where
Δx = change in the x direction
v₀ = initial velocity
t = time
a = acceleration
If the body is vertically instead of horizontally, Δx is changed to Δy
Δy = v₀t + (1/2)at²
For a vertical moving body, the acceleration it experiences is the gravitational accerelation of the earth 'g'
So the equation becomes:
Δy = v₀t + (1/2)gt²
where g = 9.81 m/s if the body is moving downwards and g = -9.81 m/s if the body is moving upwards
Answer:
Cost = $ 7.72
Explanation:
Considering the trip of 100 km, the cost spent on the fuel during the trip can be calculated by the following formula:
where,
Average Fuel Consumption = 6 liter/100 km
Unit Fuel Cost = (1.063 euros/liter)($ 1.21/1 euro) = $ 1.29/liter
Distance = 100 km
Therefore,
<u>Cost = $ 7.72</u>
