How does magnetic compass help to identify directions​

Physics
1 answer:
laila [671]3 years ago
7 0

Answer:

By the help of magnetic field of the earth

Explanation:

Compasses, also known as magnetic compass, help us primarily in navigating and determine position on the globe. The planet Earth has its own magnetosphere or magnetic field that is close with that of a magnetic poles, and this is how compass works. The compass needle aims north and south as it happens to coincide with the Magnetosphere or magnetic field.

The barrel of a rifle has a length of 0.855 m. A bullet leaves the muzzle of a rifle with a speed of 553 m/s. What is the accele
Novay_Z [31]

Answer:

Acceleration of the bullet will be 1778835.6 m/sec^2      

Explanation:

We have given length of the barrel refile s= 0.855 m

When the bullet leaves the muzzle its velocity is 553 m/sec

So final velocity v = 553 m/sec

Initial velocity will be 0 that is u = 0 m/sec

According to third equation of motion v^2=u^2+2as

553^2=0^2+2\times a\times 0.855

a=178835.6m/sec^2

A force of 10N is applied by a boy while lifting a 20,000g mass. How much does it accelerate by?
Tanya [424]

Answer:

0.5 m/s^{2}

Explanation:

20000g to kg = \frac{20000}{1000} = 20 kg

f = ma

a = \frac{f}{m}

a =\frac{10}{20}

a = \frac{1}{2}

a = 0.5 m/s^{2}

Maybe nobody ever mentioned it to you, but it turns out that
current is another one of those things that's always conserved ...
it can't created or destroyed, just like energy and mass. 

The total current in a circuit is always the same, but it can get
split up and travel through different paths for a while.

<span>==>  The total current is just the amount of current
         that's flowing in
and out of </span><span>the battery.

Diagram #1).
</span>The total current coming out of the battery is 15 A.
That current is going to split up when it reaches the resistors.
   Part of it will flow through each resistor, but both of them
   will still add up to  15 A .
You have  9 A  flowing through one resistor.
So the current in the other resistor is  (15 - 9)  =<span>  6 A.

Diagram #2).
</span>The total current coming out of the battery is 10 A.
That current is going to split up when it reaches the resistors.
   Part of it will flow through each resistor, but all of them
   will still add up to  10 A .
You have  2.5 A  through one resistor and  3.5 A through another one.
So the amount left for the last resistor is  (10 - 2.5 - 3.5)  =<span>  4 A.</span>
