Answer:
Acosθ
Explanation:
The x-component of a vector is defined as :
Magnitude * cosine of the angle
Maginitude * cosθ
The magnitude is represented as A
Hence, horizontal, x - component of the vector is :
Acosθ
Furthermore,
The y-component is taken as the sin of the of the angle multiplied by the magnitude
Vertical, y component : Asinθ
A Myocyte is probably the best answer for this question
The magnetic field between the poles of the horseshoe magnet in fig 21.4 B curves in the <u>counter clockwise direction.</u>
The magnetic field lines due to a straight current carrying conductor is given by the right hand thumb rule. This rule is stated as follows: Imagine holding the current carrying conductor in your right hand with the thumb pointing in the direction of current, then the direction in which your fingers curve around the wire gives the direction of the magnetic field lines. The direction of the magnetic field lines at a point gives the direction of magnetic field at that point.
On applying this rule, it can be seen that the magnetic field due to the conductor shown in Fig 21.4 B curves in the counter clockwise direction.

You stand on a straight desert road at night and observe a vehicle approaching. This vehicle is equipped with two small headlights that are 0.681 m apart. At what distance, in kilometres, are you marginally able to discern that there are two headlights rather than a single light source?Take the wavelength of the light to be 549 nm and your pupil diameter as 4.63 mm.
Answer:
The distance is 
Explanation:
From the question we are told that
The is distance between the headlight is 
The wavelength is 
The pupil diameter is 
Generally, we can mathematically evaluate the resolution of the eye as

substituting values

Now according to SOHCAHTOA rule

Where z is the distance at which the eye can discern the two head light
given that the angle is very small 
=> 
substituting values

=> 
=> 
Answer:
the weight of astronauts on earth is greater than his weight on d moon
Explanation:
due to the greater gravitational pull in earth the weight seems to me more
but for the moon where there is less gravity
its weight will be less causing slight flotation
