Answer:
76.25cm
Explanation:
38cm + 56cm +97cm +114cm = 305cm
305cm÷4 = 76.25cm
The heat that is required to raise the temperature of an object is calculated through the equation,
heat = mass x specific heat x (T2 - T1)
Specific heat is therefore calculated through the equation below,
specific heat = heat / (mass x (T2 - T1))
Substituting,
specific heat = 645 J / ((28.4 g)(15.5 - - 11.6))
The value of specific heat from above equation is 0.838 J/g°C.
Answer:
height(h)=10 m
acceleration due to gravity (g)=10 m/s^2
mass (m)=?
potential energy=67
or,mgh= 67
or,m×10×10=67
or,m=67/100
or,m=0.67 kg
Therefore,m= 670 grams
Answer:
lower viscosity than syrup
Answer:
The most consistent mechanism is SN1.
Explanation:
The solvolysis of tert-butyl iodide in methanol will arise by the SN1 mechanism.
The reason for that is due the geometric structure of tert-butyl. The tertiary structure allows the formation of a stable carbocation, after the loss of the iodide ion. The carbocation will then be attacked by methanol molecules forming an eter.
