Answer:

Oatmeal

They say breakfast is the most important meal of the day, and with good reason. Not only does it give you the first boost of energy to start your day, but studies have also shown breakfast eaters are at lower risk for obesity, hypertension and diabetes, in comparison to those who prefer to skip it.

While it might be tempting to savor sugary cereal or a doughnut, it’s crucial to start your day on the right note so you can stay focused, fight hunger, and avoid packing on the pounds easily. Experts recommend eating oatmeal, which is low in calories and will help you feel fuller longer. To jazz up your meal, load up on fresh fruit for a touch of sweetness or cinnamon for some spice.

Dark Chocolate

Need to perk up in the AM? Enjoy some feel-good dark cocoa rather than coffee. “Dark chocolate boosts serotonin and endorphin levels, which are associated with greater concentration,” says Natalie Stephens, clinical dietician at The Ohio State University Wexner Medical Center. “It’s also a source of antioxidants, vitamins, and minerals, such as potassium, copper, and magnesium, which can work with a healthy diet to control blood pressure. It’s also lower in fat and sugar than milk or white chocolate, which is better for diabetics and really anyone interested in cutting back on sugar intake.”

A 2013 study even concluded that those who drank two cups of cocoa every day for a month had improved blood flow to the brain, performing better on memory tests. But just like with any treat, be mindful of the calorie count and always aim for the highest quality. Experts say one square of dark chocolate during the afternoon slump should be sufficient.

Water

Seriously, sometimes all you really need is a glass of refreshing water to kick off the day, especially if you had a rough night. “Thirst and dehydration can cause fatigue,” says Moustafa. “If you reach for a cup of coffee or an energy drink, it will actually dehydrate you further, causing you to feel worse later. So before you do anything, drink a tall 10-ounce glass of water. Squeeze some fresh lemon in it for a little extra kick.”

Blueberries

Not only are blueberries wonderfully tasty and rich in antioxidants, but they've also been said to be a memory booster. A 2010 report published by the Journal of Agricultural and Food Chemistry revealed those who drank blueberry juice every day for two months significantly improved their performance on learning and memory tests. Whenever those snack cravings kick in, consider enjoying some fresh, ripe blueberries over sugary sweets any day.

Salmon

“Salmon is a concentrated source of omega-3 fatty acids, which help rebuild brain cells, slow cognitive decline, and also strengthen the synapses in your brain related to memory,” says professional health coach Lori Shemek. “The protein in salmon contains amino acids, which are essential for keeping your brain focused and sharp. Look to add salmon where you can to maximize your brain power.”

Need to jazz up your eggs for breakfast? Shemek recommends pairing them with some salmon for a satisfying meal to start your day.

Green Tea

If you’re feeling drained by mid-day, think twice before grabbing that extra cup of coffee. With those extra sugar additions, it can easily rack up your calorie intake during the day and cause unnecessary jitters. Also, too much consumption of caffeine can cause headaches, which will only hurt your concentration. While green tea has always been hailed as a coffee alternative, no two brands are created equal. Some may have less caffeine than a regular cup of coffee, which can actually be a good thing.

“Green tea does contain a more modest amount of caffeine balanced by the amino acid theanine,” says celebrity nutritionist JJ Virgin. “Studies show theanine improves mental alertness and focus. If you need that afternoon pick-me-up, green tea is your ticket.”

Beets

“This dark red root may be the new kid on the block for promoting better memory, focused concentration and overall cognition,” says Shemek. “Beets contain nitrates that can dilate blood vessels, increase blood flow and oxygen to the brain, thereby improving mental performance. Add beets to salads, roast them or add to juices for optimal brain health.”

Bananas

If you’re in a hurry, make sure to grab a banana to consume while on the go. Not only are they sweet and delish, but they can also help boost your concentration. A 2008 study found that students who ate the golden fruit before an exam actually did better than those who didn’t. Bananas highlight potassium, an essential mineral crucial for keeping your brain, nerves, and heart in tip-top shape.

Answer:

She believes he's weak and won't do what needs to be done to become a king.

Explanation:

She says ('I fear thy nature') and calls him 'too full o' th' milk of human kindness' which reflects that she feels his kindness makes him weak and may prevent him from proceeding the plan. Thus, she manipulates him to keep his kindness aside and do what she wishes him to do. She rather belittles him to get her purpose solved and

You are working as an electrical technician. One day, out in the field, you need an inductor but cannot find one. Looking in you
telo118 [61]

Answer:

a) the inductance of the coil is 6 mH

b) the emf generated in the coil is 18 mV  

Explanation:

Given the data in the question;

N = 570 turns

diameter of tube d = 8.10 cm = 0.081 m

length of the wire-wrapped portion l =  35.0 cm = 0.35 m

a) the inductance of the coil (in mH)

inductance of solenoid

L = N²μA / l

A = πd²/4  

so

L = N²μ(πd²/4) / l

L = N²μ(πd²) / 4l

we know that μ = 4π × 10⁻⁷ TmA⁻¹

we substitute

L = [(570)² × 4π × 10⁻⁷× ( π × (0.081)² )] / 4(0.35)

L =  0.00841549 / 1.4

L = 6 × 10⁻³ H    

L = 6 × 10⁻³ × 1000 mH

L = 6 mH

Therefore, the inductance of the coil is 6 mH

b)

Emf ( ∈ ) = L di/dt

given that; di/dt = 3.00 A/sec

{∴ di = 3 - 0 = 3 and dt = 1 sec}

Emf ( ∈ ) = L di/dt

we substitute

⇒ 6 × 10⁻³ ( 3/1 )

= 18 × 10⁻³ V

= 18 × 10⁻³ × 1000

= 18 mV  

Therefore, the emf generated in the coil is 18 mV

A fatigue test was conducted in which the mean stress was 46.2 MPa and the stress amplitude was 219 MPa.
sleet_krkn [62]

Answer:

a)σ₁ = 265.2 MPa

b)σ₂ = -172.8 MPa

c)Stress\ ratio =-0.65

d)Range = 438 MPa

Explanation:

Given that

Mean stress ,σm= 46.2 MPa

Stress amplitude ,σa= 219 MPa

Lets take

Maximum stress level = σ₁

Minimum stress level =σ₂

The mean stress given as

\sigma_m=\dfrac{\sigma_1+\sigma_2}{2}

2\sigma_m={\sigma_1+\sigma_2}

2 x 46.2 =  σ₁ +  σ₂

 σ₁ +  σ₂ = 92.4 MPa    --------1

The amplitude stress given as

\sigma_a=\dfrac{\sigma_1-\sigma_2}{2}

2\sigma_a={\sigma_1-\sigma_2}

2 x 219 =  σ₁ -  σ₂

 σ₁ -  σ₂ = 438 MPa    --------2

By adding the above equation

2  σ₁ = 530.4

σ₁ = 265.2 MPa

-σ₂ = 438 -265.2 MPa

σ₂ = -172.8 MPa

Stress ratio

Stress\ ratio =\dfrac{\sigma_{min}}{\sigma_{max}}

Stress\ ratio =\dfrac{-172.8}{265.2}

Stress\ ratio =-0.65

Range = 265.2 MPa - ( -172.8 MPa)

Range = 438 MPa
