A 1200-nF capacitor with circular parallel plates 2.0 cm in diameter is accumulating charge at the rate of 35 mC/s at some instant in time. (A) What will be the magnitude of the induced magnetic field 10.0 cm radially outward from the center of the plates?

Answers

Answer 1

Answer:

Answer:

$B = 7 * 10^(-8) T$

Explanation:

As we know that charge on the plates of capacitor is changing at rate given as

$i = (dq)/(dt) = 35 mC/s$

now this rate of charging the plates will give the displacement current in the region between the plates

Now by Ampere's law we can say

$\int B . dl = \mu_0 i$

now we have

$B(2\pi r) = \mu_0 i$

$B = (\mu_0 i)/(2\pi r)$

$B = (2 * 10^(-7) (35 * 10^(-3)))/(0.10)$

$B = 7 * 10^(-8) T$

Animals in cold climates often depend on two layers of insulation: a layer of body fat [of thermal conductivity 0.200W/(m⋅K) ] surrounded by a layer of air trapped inside fur or down. We can model a black bear (Ursus americanus) as a sphere 1.60m in diameter having a layer of fat 3.90cm thick. (Actually, the thickness varies with the season, but we are interested in hibernation, when the fat layer is thickest.) In studies of bear hibernation, it was found that the outer surface layer of the fur is at 2.80∘C during hibernation, while the inner surface of the fat layer is at 30.9∘C a) What should the temperature at the fat-inner fur boundary be so that the bear loses heat at a rate of 51.4W ? b) How thick should the air layer (contained within the fur) be so that the bear loses heat at a rate of 51.4W ?

A a0 is the amount of heat needed to raise the temperature of one kilogram of water one degree centigrade.

Answers

The correct answer that would best complete the given statement above would be the term KILOCALORIE. A KILOCALORIE is the amount of heat needed to raise the temperature of one kilogram of water one degree centigrade. On the other hand, the amount of heat needed to raise the temperature of one gram of water one Centigrade degree is calorie. Hope this answer helps.

I got this correct on Odyssey-ware the answer is Kilocalorie

A spring gun consists of a spring inside a plastic tube with spring constant, k. The spring can be compressed 20 cm from its equilibrium length. A 100 g hard plastic ball is then loaded into the tube. If the ball is shot directly up and reaches a height of 2 m above the top of the tube, what is the spring constant, k? Ignore air resistance.A) 98 N/m
B) 20 N/m
C) 12 N/m
D) 25 N/m
E) 390 N/m

Answers

Answer: The spring constant is K=392.4N/m

Explanation:

According to hook's law the applied force F will be directly proportional to the extension e produced provided the spring is not distorted

The force F=ke

Where k=spring constant

e= Extention produced

h=2m

Given that

e=20cm to meter 20/100= 0.2m

m=100g to kg m=100/1000= 0.1kg

But F=mg

Ignoring air resistance

assuming g=9.81m/s²

Since the compression causes the plastic ball to poses potential energy hence energy stored in the spring

E=1/2ke²=mgh

Substituting our values to find k

First we make k subject of formula

k=2mgh/e²

k=2*0.1*9.81*2/0.1²

K=3.921/0.01

K=392.4N/m

An oil tanker, initially traveling west at 18 km/h is accelerated uniformly until it is traveling east at 21.6 km/h. The acceleration is 0.20 m/s2 towards the east. Compute the total displacement from the tanker’s initial position.Answer in meters.

Answers

Answer:

27.5 m

Explanation:

Given:

u = 18 km/h = 5 m/s

v = 21.6 km/h = 6 m/s

a = 0.20 m/s²

Find: s

v² = u² + 2as

(6 m/s)² = (5 m/s)² + 2 (0.20 m/s²) s

s = 27.5 m

Bjorn is holding a tennis ball outside a second floor window (3.5 meters from the ground) and billie jean is holding one outside a third floor window (6.25 meters from the ground) how much more GPE does billie jean's tennis ball have? (each tennis ball has a mass of 0.06 kg)

Answers

The answer is 1.01 x 10^(-11) N. I arrived to this answer through calculating the GPEs of both balls. Bjorn's ball has a GPE of 1.402 x 10^(-11) N. Billie Jean's ball has a GPE of 2.503 x 10^(-11) N. I subtracted the two and I found that Billie Jean's tennis ball has a GPE of 1.01 x 10^(-11) more than Bjorn's tennis ball.
