Answer:
140 beats per minute
Explanation:
There are 60 seconds in a minute and we know that Sherry felt 14 beats in 6 seconds if you multiply 6 by 10 you get 60 seconds which can be 1 minute. Then you multiply 14 by 10 since you 14 by 10 since you multiplied 6 by 10 and you get 140 beats per minute.
Answer
According to prevailing gender stereotypes most important characteristics associated with men and woman are as follows
1. Domestic behaviors is one of the basic stereotypes. Some people have thinking that women will cook for family, she will take care of the children, she will do loundary and will clean the house. About man they thought he will take care of finances, will pay the bills and do the home repairs.
2. Some people thought that women are emotional and submissive, while men are thought to be self-confident and aggressive.
3.Some people thought that the most common occupation for women are teaching and nursing while the rest of the occupation are for men like pilots, doctors, and engineers are men.
4. Men are expected to be tall and strong while women are expected to be thin and graceful, while.
5. Dressing of men and women also thought to be different. Usually men expected to wear pants and short hairstyles whele women are expected to wear goun, frouks and make-up.
Answer:
17.97m/s
Explanation:
Density of air (ρ)air=1.23 kg/m3, and
Air speed (V) =20 m/sec, pressure gradient along the streamline, ∂p/∂x = 100N/m^3.
The equation of motion along the stream line directions:
considering the momentum balance along the streamline.
γsinθ-∂p/∂x=ρV(∂V/∂x)
Neglecting the effect of gravity , then γ=ρg=0
So, ∂p/∂x= -ρV(∂V/∂x)
∂V/∂x= - 100/(20X1.23)= -4.0650407/S
Also δV/δx=∂V/∂x
∂V/∂x=-4.0650407/S and δx=0.5 m
δV = (-4.0650407/S) *(0.5m)
δV = -2.0325203 m/S
So net air speed will be V+δV= -2.0325203+20 ≅17.96748 m/s
Approximately, V+δV=17.97m/s.
Answer:
0.0545 m/s2
Explanation:
19.2 cm = 0.192 m
We can convert rpm (revolution per minute) to angular velocity rad/s knowing that each revolution is 2π rad and each minute is 60 seconds.
57 rpm = 57 * 2π / 60 = 6 rad/s
86 rpm = 86 * 2π / 60 = 9 rad/s
The angular acceleration of the sprocket is the change in angular velocity per unit of time
The tangential acceleration of the pedal is the product of its angular acceleration and the radius of rotation, aka the pedal arm length L = 0.192 m
Answer: 42 N-s
Explanation: The area under the curve is equal to the impulse, so you take the area of the two triangles and add it to the area of the rectangle.
Area of a triangle: 1/2bh
Area of a rectangle: bxh
2(1/2x2x7)=14+(4x7)=42 N-s
