Answer:
Meandering
Explanation:
A meander is known as the continuous flow of regular curves which are sinuous, loops, turns, bends or winding in the channel of river
Production of a meander by a river or stream as it erodes the sediments comprising on an exterior, a concave bank and deposits it and other sediment on the downstream on an interior, convex bank which is like a point bar.
Rivers or streams with a one channel and sinuosities of 1.6 or more are defined as meandering rivers or streams.
Efficiency of heat engine is determined by the ratio of difference in temperature of cold from hot reservoir to the temperature of hot reservoir over temperature of hot reservoir.
Answer: Option A
<u>Explanation:</u>
Efficiency is defined as the output from the input. So it is the ratio of energy output to the energy input. In case of temperature, it is the change in temperature from hot reservoir to cold reservoir with the overall hot reservoir temperature.
Thus, option A is the most suitable as the heat will be transferred from high temperature to low temperature. So the hot reservoir will be releasing the energy. So the conversion of hot reservoir temperature to cool reservoir temperature is defined as the efficiency. Thus, option A is the most suitable.
Answer: 0.00000938422m^3
Explanation:
dV=Vø*β*(t1-tø)
The parameters are
dV is the change in volume after temperature increase
Vø =0.607 *10^-3m3 is the initial vokume of coffe at 16.2^0 C
β= coefficient of volume expansion of water at 16.2^0 C is 0.0002/0C
t1= 93.5^0C final temperature
tø=16.2^0 C
Therefore
dV=0.607 *10^-3 *0.0002*(93.5-16.2)
dV= 0.00000938422m^3
This is the volume of coffee that will spill over the container
Answer:
D. 30m/s
Explanation:
According to the equation of motion
v=u +at
v = Final velocity
u = initial velocity
a = acceleration
t = time taken
Since we don't know the acceleration of the body, we will find its acceleration using newtons first law of motion F = ma
10000 =2000a
a = 5m/s²
initial velocity = 0m/s since the body starts from rest
v is what we are looking for
t = 6seconds
Substituting this datas in the formula
v = 0+ 5(6)
v = 30m/s (D)
