Two coils have the same number of circular turns and carry the same current. Each rotates in a magnetic field acting perpendicul

Delicious77 [7]

Answer:

The radius of coil 2 = 2.7 cm

Explanation:

The number of coils = 2

It is given that both carry equal current and rotates in the magnetic field.

The given radius of coil 1 = 4.0 cm

Coil 1 rotates = 0.21 T field

Coil 2 rotates = 0.45 T filed.

The radius of coil 2 need to be calculated.

Torque action on dipole is given by $T =NIABsinθ$

here T1 = T2

$r1^{2} \times B1 = r2^{2} \times B2 \\r2^{2} = 0.04 \times 0.04 \times \frac{0.21}{0.45} \\r2 = 0.027m \ or \ 2.7 cm \\$

Suppose a truck has a momentum of 40,120 kg • and a mass of 1,180 kg. What is the truck’s velocity?

gladu [14]

Answer:

The velocity of the truck is 34 m/s.

Explanation:

The momentum (p) of an object is the product of its mass (m) and its velocity (v) which can be written as:

p = mv

Here in this problem, we are given a truck which has a momentum of 40120 kg and a mass of 1180 kg and we are to find its velocity.

So substituting the given values in the above formula to find the velocity of the truck.

Truck's velocity = $\frac{40120}{1180}$ = 34 m/s.

Under which condition will air behave as conductor? a) low altitude b) high humidity c) low humidity d) high pressure

Solnce55 [7]

Air is a better conductor when the humidity is high.

That's why you cannot zap your sister on a humid or rainy day,
even after scuffing your feet on the carpet. The charge that you
build up from the carpet quickly flows away from you through the air.
