Answer:

B. Removing its iron core

Explanation:

In an electromagnet role of its core is very important as it concentrate magnetic flux to make magnetic field more powerful. Generally core of electromagnet is made up of a ferromagnetic material or of a ferrimagnetic material such as iron. Adding batteries to the circuit and increasing the current through the coil and increasing loops in the coil will increase magnetic  strength of an electromagnet.

Answer:

B. removing its iron core

Explanation:

The iron core inside of the wire coil increases the strength of an electromagnet. So removing the iron core would decrease the strength of an electromagnet.

Answer:

O

Explanation:

Answer:

Yes

Explanation:

The truck has momentum since it is moving and momentum is a product of mass and velocity. After impact, part of momentum that the truck had is transferred to the car hence the car initially at rest moves a significant diatance. Here, we utilize the formula MV= (m+M)v where M and V represent mass and velocity of the truck while m is the mass of car, v is the common velocity. Note that some letters are capital while others small, don't confuse these.

The x-component of the vector is 36.55 m.

Components of vectors

The components of a vector include both x and y components. The x-component is determined along x-axis, while y-component is determined along y-axis.

Vx = Vcosθ

Vy = Vsinθ

where;

• Vx is the x-component of the vector
• Vy is the y-component of the vector

X-components of the vector

The x-component of the vector is calculated as follows;

x = 47.3 x cos(39.4)

x = 36.55 m

Thus, the x-component of the vector is 36.55 m.
