Answer:

It will slow down your reaction time, and reducing ability to control the boat and it will give physical fatigue .

Explanation:

When you aboard a boat you are subjected to both low and high frequencies from the wind and from the engine of the boat. You can feel the waves which are of low frequency as a vibration.

Like other machines boat can produce noise and vibration together that will make you tired, and in some cases your reaction times will slow down and you will loose the ability to control that boat.

After that the heat and glare from the sun will also make you physically fatigue and in this condition operating a boat is more dangerous.

docker41 [41]

Answer:

D. The object will continue to move with a constant velocity

Explanation:

According to Newton's first law also known as law of inertia, states that an object at rest will remain at rest or, if in motion, will remain in motion at constant velocity unless acted on by a net external force.

Therefore, An object moving in the absence of a net force will continue to move at a constant velocity

What is the period of 60.0 hz electrical power?

Anarel [89]

Answer:

0.017 s

Explanation:

The period of a periodic signal is defined as the reciprocal of the frequency:

$T=\frac{1}{f}$

where

T is the period

f is the frequency

For the electrical power, the frequency is

f = 60.0 Hz

Substituting into the previous equation, we find the period:

$T=\frac{1}{60.0 Hz}=0.017 s$

If electrical current is moving through a horizontal wire toward your face, what direction is the induced magnetic field?

adoni [48]

Answer:(b)

Explanation:

Given

Electric current flowing through the horizontal wire towards the observer's face.

The direction of the magnetic field is given by the right-hand thumb rule, i.e. place the thumb in the direction of current and the wrapping of fingers will give the direction of the magnetic field

the direction of the magnetic field will be counterclockwise as observed by an observer.

A man goes 150 m due east and then 200 m due north how far is he from starting point

grin007 [14]

Answer:

250 m

Explanation:

Since North and East are 90 degrees from each other, we can treat this as a right-angled triangle, with the distance in each direction being the sides and the distance from the starting point being the hypotenuse.

Hence, sqrt(150^2+200^2) = 250 m.

Hope this helped!
