It would be safe to stand on the insulated sphere since it is covered by a material that does not allow the passage of current or an insulator. With the insulator, the student can freely touch the sphere but without it, touching the sphere when it is charged is very dangerous as it would electrocute you since the charge from the sphere would freely flow onto your body. Insulators are being used to be able to protect humans from any danger in touching charged objects. Insulators have very high resistance to the flow of current through them. Examples are rubber, glass, cellulose, polystyrene and wood.

Recall the relationship between the charge on a capacitor and the potential difference across the capacitor. Use this relationsh
charle [14.2K]

Answer:

Answer in explanation.

Explanation:

The relationship between the charge on the capacitor and the potential difference across it is given as follows:

Q = CV

where,

Q = Charge on the Capacitor

C = Capacitance of the Capacitor

V = Potential Difference across the Capacitor

This relationship can be used to find the charge on a capacitor, using the voltmeter, as follows:

<u>The potential difference can be measured through the voltmeter. And the capacitance of the capacitor is a known constant value. Therefore, the charge can be found by taking product of both.</u>

You lift a 45-newton bag of mulch 1.2 meters and carry it a distance of 10 meters to the garden. How much 
zysi [14]
To lift the bag straight up takes (F · D) = (45 · 1.2) = 54 joules of energy (work).

Moving the bag horizontally 'across' gravity requires no work.
It doesn't matter how far.

A manufacturer provides a warranty against failure of a carbon steel product within the first 30 days after sale. Out of 1000 so
hodyreva [135]

Answer:A) Risk(R)= $1000

B) There is justification for spending an additional cost of $100 to prevent a corrosion whose consequence in monetary terms is $1000

Explanation:R= Risk,

P=Probability of failure

C= Consequence of failure

Mathematically, R=P ×C

10 out of 1000 carbon-steal products failed

Probability of failure= 10/1000 =0.01

The consequence of failure by corrosion given in monetary term =$100,000

Risk of failure = 0.01 × $100,000

R=$1000
