A long, straight, horizontal wire carries current toward the east. A proton moves toward the east alongside and just south of th
kondor19780726 [428]

Answer:

north direction.

Explanation:

The wire carries a current towards the east . The magnetic field will make circular path around the wire in clockwise direction  so at a point just south of wire , magnetic field will be into the plane of paper containing wire. If we take east as x -axes , north as y axes then out of plane will form z axes. Hence direction of magnetic field will be -  z direction .

Magnetic field can be represented as - B k

Proton is moving towards east ie in + x direction so it can be represented as follows

velocity = V i

Force F = q( V i x -B k)

= ( BqV) j or + ve j direction or along north direction

So direction of force will be along north direction.

If a solar photovoltaic panel produces 1,000 watts of electrical energy and is active for 12 hours each day, how many kwh of ele
Masteriza [31]

Answer;

=84 kwh

Explanation;

Electrical energy = 1000 watts

1000 watt = 1 kilo watt

1 week = 7 days

Number of hours = 7 × 12× = 84 hours

Consumption

= 1 kw × 84 hours

= 84 kwh

A firm wants to determine the amount of frictional torque in their current line of grindstones, so they can redesign them to be
victus00 [196]

Answer:

a)- 1.799 rad/sec²

b)- 17.6 x 10ˉ³Nm

Explanation:

ω₀ = 720 rev/min x (1 min/60 sec) x (2π rad / 1 rev) =  24π rad/s

a) Assuming a constant angular acceleration, the formula will be

α = (ωf -ω₀) / t

As final state of the grindstone is at rest, so ωf =0

⇒ α = (0-24π) / 41.9 = - 1.799 rad/sec²

b)Moment of inertia I for a disk about its central axis

I = ½mr²  

where m=2kg and radius 'r'= 0.099m

I = ½(2)(0.099²)

I = 9.8 x 10ˉ³ kgm²

Next is to determine the frictional torque exerted on the grindstone, that caused it to stop, applying the rotational equivalent of the Newton's 2nd law:

τ = I α =>(9.8 x 10ˉ³)(- 1.799)

τ = - 17.6 x 10ˉ³Nm

(The negative sign indicates that the frictional torque opposes to the rotation of  the grindstone).
