A boat is towing two skiers at the same time. how long should the tow lines be?

1 answer:

4 0

The tow lines for the two skiers must be of the same length. No matter the number of skiers towed, the length of the tow lines must be the same. Towing people on ski requires additional skills and some safety precautions must be taken. Most importantly, it is dangerous and illegal to tow at night.

A beam oflight is reflected off a mirror. If the angle of incidence is 30 degrees, according to the Law of Reflection the angle

zaharov [31]

Answer:

30°

Explanation:

According to the second law of reflection, it States that the angle of incidence i is equal to the angle of reflection r.

The angle of incidence is known to be the angle between the incident ray and the normal.

The Angle of reflection is the angle between the reflected ray and the normal.

This normal ray is a ray that is perpendicular to the surface.

According to the question, if the beam of light is reflected off the surface and its angle of incidence is 30°, its angle of reflection will also be 30° i.e i=r = 30°

A leaf falls thorough the air, floating as it falls. Air resistance is visible affecting the leaf . Which two properties of the

vaieri [72.5K]

The two properties of the leaf that allow it to be affected by air resistance include its distance from the ground and its mass.

Mass is a scalar quantity that measures the inertia of a given body and/or object, which represent one of the most important characteristics of the matter.

This measurement (mass) may affect the flight of an object because mass inertia is associated with gravity and does not allow its movement.

In conclusion, the two properties of the leaf that allow it to be affected by air resistance include its distance from the ground and its mass.

Find an expression for the electric field E⃗ at the center of the semicircle. Hint: A small piece of arc length Δs spans a small

Hatshy [7]

Answer:

Electric Field a the centre $E=\dfrac{Q}{2\pi^2\epsilon_0 R^2}(-\vec j)$

Explanation:

<u>Given:</u>

Total charge on the semicircle =Q

Radius of the semicircle=R

Let consider a elemental charge on the semicircle at an angle $\theta\\$ with the horizontal. Since the The charge distribution is symmetrical about y axis so the there will symmetrical charge on other side. The horizontal component will cancel out each other and vertical component will get added so let dE be the electric Field due to elemental charge
