My Fitness Goals: (List your specific and general goals)
Leokris [45]
-Try one new workout every month. Keeping the same exact routine when it comes to your fitness is never a good thing.

-More water
With any diet, the most important thing to remember is to stay hydrated. Drinking water will support your body with digestion, transporting nutrients to your bones and muscles, and even improving cognitive function.
Ideally, you want to drink about half your body weight in ounces per day, i.e. if you weight 150 pounds, you should drink 75 ounces of water a day.

-Stretching
The benefits are vast and the repercussions of failing to stretch can be dramatic.
Do yourself a favor and always stretch before and after a workout. This will promote a healthy cool down, improve flexibility, and reduce next day aches. Failure to stretch can lead to injures and muscle damage.

-Body Fat
This may seem like an obvious one, but it is one of the most important steps to a healthier you. Reducing your body fat has a lot of benefits such as:

Improved joints and tendons
Lowered risk of diabetes
Reduced risk of heart disease
Reduced inflammation
Better performance and endurance
Improved appearance and confidence
Better hormonal profiles in your body
Remember, it is not a race to see how quickly you can decrease your body fat. Healthy weight loss is around 1-2 pounds a week for your fitness goals.[2]

Crash dieting or pushing yourself too much in the gym can lead to you achieving an unrealistic target, and you may find yourself gaining all the weight you have lost.

Think of it as a lifestyle, and take it slow and steady.

What is the answer? Explain best and I will mark brainliest!
iVinArrow [24]
I would say B because it is near the ocean which can cause a tsunami but also because of the wind coming from the ocean (it might cause hurricanes and lots of storms) I’m not sure though but that’s what I think makes sense. Good Luck!

Assume that the pictured magnet is being moved into the solenoid. If the polarity of the magnet is reversed and then moved into
KonstantinChe [14]

Answer:

The direction of induced emf is revered and hence the direction of the induced current.

Explanation:

If the polarity of the magnet is reversed, the direction if the field lines through the solenoid is also reversed, which according to Faraday's law means

\varepsilon  =N\dfrac{d\Phi}{dt} \rightarrow -N\dfrac{d\Phi}{dt}

in other words, the direction of the magnetic flux is revered, and therefore, the direction of the induced emf is also revered.

Furthermore, according to Ohm's law

I = \dfrac{\varepsilon}{R}

which tells us that if the induced emf changes sign <em>(is reversed)</em>

I = -\dfrac{\varepsilon}{R}

the direction of the induced current is also reversed.

Derek and Wes take a photograph of a lake at the same angle and the same time of day. Derek's picture comes out with crisp edges
iren [92.7K]

Answer: Polarization

Explanation:

Probably what happens here is that Derek took his photograph with a polarizing filter (which is helpful to avoid that glare from the surface of water, for example), and Wes took his without that filter.

It is important to note, this kind of filter works with an optical phenomenon called polarization, which consists in the alignment of light (electromagnetic waves) in only one vibrational orientation.

To understand it better:

Normally, electromagnetic waves are not polarized, and the vibration occurs in all planes. However, if we make these waves to vibrate in a single plane, we have polarized light.

<u>This is only possible because electromagnetic waves are transversal waves</u>, hence the oscillation occurs in the transversal direction to the propagation.

Note this is not possible for longitudinal waves (sound), because the oscillation occurs in the same direction as the propagation.

A ball is thrown with an initial speed of 10. Meters per second. At what angle above the horizontal should the ball be thrown to
maria [59]

The initial speed doesn’t matter.  To reach the maximum height, you need to launch straight up ... 90 degrees above horizontal.
