Answer:
Total work done is 2606.08 J.
Explanation:
Given :
Mass of box , m = 23 kg .
Force applied , F = 100 N .
Angle from horizon , .
Coefficient of kinetic friction , .
Distance travelled by box , d = 34 m .
Now ,
Total work done = work done by boy + work done by friction.
Hence , this is the required solution.
Answer:
Value of each charge is given as
Explanation:
As we know that electrostatic force between two charges is given as
here we know that
r = 0.100 m
now we have
Answer:
a) P = 15993.6 N/m²
b) P' = 11062.24 N/m²
Explanation:
Given:
Density of the mercury, ρ = 13.6 × 10³ kg/m³
The blood pressure reading is given as 120 over 83 mm
a) Now,
The pressure (P) due to a fluid is given as:
P = ρgh
where, g is the acceleration due to the gravity
h is the pressure head
The systolic pressure head from the blood pressure reading is , h = 120 mm = 0.12 m
substituting the value in the formula for pressure,
we get
P = 13.6 × 10³ × 9.8 × 0.12
or
P = 15993.6 N/m²
b) The systolic pressure head from the blood pressure reading is , h' = 83 mm = 0.083 m
substituting the value in the formula for pressure,
we get
P' = 13.6 × 10³ × 9.8 × 0.083
or
P' = 11062.24 N/m²
Answer:
First product is FCH-OH chemically known as 2-[2-furyl(hydroxyl)methyl]-Second product is FCH i.e (2E)-2-[2-furyl-methylene]-cyclohexanone
Explanation:
Please see the attached image for complete chemical reaction of aldol condensation of cyclohexanone
Aldol Condensation is a form of electrophilic substitution reaction in which the alpha carbon in enols or enolate anions is substituted by an electrophile to form carbon-carbon bond. Cyclohexanone also known as the first ketone consists of two alpha-carbons and four potential substitutions i.e alpha-hydrogens but none of the hydrogen on the ring is substituted. Ketones such as cyclohexanone are much more acidic than their parent hydrocarbon.
First product is FCH-OH chemically known as 2-[2-furyl(hydroxyl)methyl]-cyclohexanone that further undergoes dehydration resulting into FCH i.e (2E)-2-[2-furyl-methylene]-cyclohexanone
Based on the explanations above, the compound formed is shown in the image.
Hello there!
To find the speed when you have the kinetic energy and the mass, you just start with the kinetic energy formula then solve for speed.
Kinetic energy =
V =
V =
V = 0.02334
Thus, the speed is 0.02 m/s
I hope this helps!
