What is the structure of a hydrocarbon that has $\mathrm{M}^{+}=120$ in its mass spectrum and has the following $1 \mathrm{H}$ NMR spectrum? 7.25 $\delta(5 \mathrm{H}, \text { broad singlet); } 2.90 \delta(1 \mathrm{H}, \text { septet, } J=7 \mathrm{Hz}) ; 1.22 \delta(6 \mathrm{H},\text { doublet, }$ $J=7 \mathrm{Hz})$
Answer:
38.33°C
Explanation:
Applying,
180/100 = (F-32)/C............. Equation 1
Where F = Temperature of the hot day in fehrenheit, C = Temperature of the hot day in centigrade.
make C the subject of the equation
C = 100(F-32)/180.............. Equation 2
From the question,
Given: F = 101°F
Substitute into equation 2
C = 100(101-32)/180
C = 38.33°C
Answer:
B. Displacement
Explanation:
The area under a velocity time graph is equal to the displacement of objects.
The direction of the angular velocity of the single wheel is the clockwise direction
<h3>Angular velocity</h3>
The angular velocity is the number of revolutions per second of the single wheel. It is given by ω = v/r where
- v = linear speed of the wheel and
- r = radius of the wheel.
<h3>Direction of the angular velocity of the single wheel</h3>
Since the wheels moves forward and the velocity of the wheel is always tangential to the wheel causing it to move forward, its angular velocity is in the clockwise direction
So, the direction of the angular velocity of the single wheel is the clockwise direction
