If you were to walk toward a van der graaff generator, the effect of its electrical field would get weaker as you walked towards it. true or false

This is False.  

If you walk towards a Vander Graaff generator and touch it, your body will be electrically charged with the same sign as the generator (that’s why your hair stands up, because it is charged with static electricity, and…electrical charges of the same sign repel each other)

Note that the Vander Graaff generator is isolated from the ground, so, if the electrical charge is increased, electrical arcs will form and fly off it to any nearby grounded object or person.

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards

find the surface area of the sphere to the nearest square unit. use a calculator.

a. 254 in.2

b. 64 in.2

c. 127 in.2

d. 1,018 in.2
