What is one way that an electric field is different from a magnetic field?

liubo4ka [24]

Answer with Explanation:

Electric field:It is the force per unit charge experienced by rest charge at any given point.

It is the area around the charge which is placed at rest.It is represented by E.

Mathematical formula:

$E=\frac{F}{q}$

Magnetic field:It is an area around moving charge in which moving charge particle experienced magnetic force in that area.

Magnetic field is represented by B.

Mathematical formula :

$F=qvBsin\theta$

Where B=Magnetic field

q=Charge on particle

v=Velocity of particle

F=Magnetic force exert on particle

You and your friend are stranded on a raft of mass 1000 kg which is not moving, you can neglect friction between the boat and th

Papessa [141]

Answer:

Mass of raft=m1= 1000kg

Mass of paddle=m2=40kg

Speed of paddle=v2=3 m/s

Speed of raft=recoil speed=v1=?

Formula

V1= -(m2/m1)v2= -(40/1000)3= - 0.12m/s

Explanation:

Here the raft has much greater mass as compare the paddle and its velocity will always be negative due to recoil. 1 and 2 with masses and velocities are subscripts.

6. What is the change in temperature of a metal rod that is 55.0 cm long, decreases length by 0.20 cm, and that has a coefficien

MrMuchimi

Explanation:

We have,

Length of a metal rod is 55 cm or 0.55 m

Change in length is 0.2 cm or 0.002 m

It is required to find the change in temperature of a metal rod. The coefficient of linear expansion is given by :

$\alpha =\dfrac{\Delta L}{L_0\Delta T}$

$\Delta T$ is the change in temperature

$\Delta T =\dfrac{\Delta L}{L_0\alpha }\\\\\Delta T =\dfrac{0.002}{0.55\times 12\times 10^{-6}}\\\\\Delta T= 303.03^{\circ} C$

So, the change in temperature is 303.03 degrees Celsius.
