Answer:
the helis speed increased its speed by 35 m/s. Unless you are asking me what was the speed per second. if you were asking me for the speed per second then that would be a different answer
Explanation:
ATP ( adenosine triphosphate )
<h2>
Answer:5
,133.6
,51.18
</h2>
Explanation:
Let , be the horizontal and vertical components of velocity.
Question a:
Horizontal component of velocity is the ratio of range and time of flight.
So,horizontal component of velocity is
So,
Question b:
Time of flight=
So,
Maximum height is given by
So,maximum height is
Question c:
The vertical velocity is already calculated in Question b.
Padded dashboards make automobiles safer because it will increase the time required to stop your head from moving forward during an accident. The increased stopping time results in a smaller force being applied to the person's head.
You need an additional point of data here: the enthalpy of fusion, or conversely the enthalpy of melting (they differ only by their sign). For water (or ice) that value is gotten from sources such as the internet
<span>ΔH°(fus) = 6.01 kJ/mole </span>
<span>Since you have 35 000g, how many moles do you have? </span>
<span>Moles H2O = 35000 g/(18.015 g/mole) = 1942.8 moles</span>
<span>So, take that ΔH°(fus) in kJ/mole, multiply by the number of moles, and there ya go!
</span>
6.01 x 1942.8 = 11,676 kJ of energy is released
