Answer:
2315.8 m/s
Explanation:
For the charged particle to pass through this field undeflected, the electric force and the magnetic force acting on it must be equal
Electric force = Magnetic force
Electric force = Eq
Magnetic force = qvB
qvB = Eq
v = (E/B)
E = 440 N/C, B = 0.19 T
v = (440/0.19)
v = 2315.8 m/s
Because the core is the hottest place at which it holds the most heat to bring it out to be towards africa.

Explanation:
To find the answer use the equation speed of light=wavelength multiplied by frequency (c=lambda*f) by substituting the value for the frequency the the speed of light
Answer:
1Kilowatt =1000watts
Now
Energy =Power x time
We need our power in Kilowatt and Our time in hours
Given
Power = 1200Watt
Divide this by 1000... To get its value in Kilowatt
Power = 1.2kilowatt
Time=6min
Divide by 60 to get its value in hours
Time = 6/60hr = 0.1hrs
Energy = 1.2kilowatt x 0.1hrs
=0.12kilowatt hours
1). The little projectile is affected by friction all the way through the block.
Friction robs some kinetic energy.
2). The block is affected by friction as it scrapes along the top of the post.
Friction robs some kinetic energy.
3). The block is also affected by friction with the air (air resistance) as it
falls to the ground. Friction robs some kinetic energy.
