Answer: The correct answer is "magnetic field".

Explanation:

A magnetic field is produced around the current carrying wire.

If you bring compass needle around the current carrying wire then it shows the deflection which indicates that there is a magnetic field around the current carrying wire.

Magnetic fields are the area around the surrounding of magnet in which magnetic force can be experienced.

Therefore, a magnetic field is produced around a wire when an electrical current is in the wire.

a 2.6 kg block is attached to a horizontal spring that has a spring constant of 126 N/m. At the instant when the displacement of

NeTakaya

Answer:

The acceleration of the object is $5.57\ m/s^2$ .

Explanation:

Given that,

Mass of the block, m = 2.6 kg

Spring constant of the spring, k = 126 N/m

At the instant when the displacement of the spring from its unstained length is 0.115 m. We need to find the acceleration of the object.

When the block is displaced, the force acting on the spring is equal to the force due to its motion. Such as :

$kx=ma$

a is acceleration of the object

$a=\dfrac{kx}{m}\\\\a=\dfrac{126\times 0.115}{2.6}\\\\a=5.57\ m/s^2$

So, the acceleration of the object is $5.57\ m/s^2$ .

If 500g of water at 20 degrees C is mixed with 750g of water at 30 degrees C, what will the temperature of the mixture be?

hjlf

Answer:

$26 ^\circ C$

Explanation:

Given that the temperature of $500g$ of water and $750 g$ of water are

at $20^{\circ}C$ and $30^\circ C$ respectively.

Let $m_1=500g$ , $T_1= 20^\circ C$

and $m_2=750g$ , $T_2= 30^\circC$ .

The specific heat capacity of water is,

$C= 4.186 J/g ^\circ C$ .

Let the final temperature of the mixture be $T^\circ C$ .

As there is no energy loss, so, the energy loss by the water at higher temperature, i.e. $30^\circ C$ , will be equal to the energy gain by the water at lower temperature, i.e. $20^{\circ}C$ .

$m_2C (T_2-T)=m_1C(T-T_1)$
