Physics
1 answer:
Natali [406]4 years ago
7 0

"Time" has no beginning, no end, and no definite length.

An interval is a piece cut out of time.
It has a beginning, an end, and a definite length.

I just made this up, but I humbly assert that it's got
everything you need to know about an interval of time.

A 15-turn circular wire loop with a radius of 3.0 cm is initially in a uniform magnetic field with a strength of 0.5 T. The fiel
miskamm [114]

Answer:

0.212V

Explanation:

The induced emf in circular loop is \epsilon=-d\frac{\phi_B}{dt}=-NA\frac{dB}{dt}

N = Number of loops = 15

A = Cross sectional Area = \pi0.03^{2} = 0.0009\pi

dB = change in magnetic Field = 0-0.5 = -0.5

dt = time taken = 0.1sec

\epsilon=-15*0.0009\pi *\frac{-0.5}{0.1} = 0.212V

Two cats are sitting on a 30 m hill. One cat
V125BC [204]

Answer:

Cat with 6 kg sitting on a 30 meter hill has greater potential energy.

Explanation:

gravitational potential energy (J) = mass (kg) × gravitational field × height (m)

<h3 /><h3><u>Note</u>:</h3>

gravitational field in Earth is 10 N/kg = <u>fixed unit</u>

<h3 /><h3><u>Given</u>:</h3>

1st Cat: 4 kg

2nd Cat: 6 kg

Both of their height is 30 meters.

<h3><u>Solve for g.p.e</u>:</h3>

1st cat = mgh = 4 × 10 × 30 = 1200 Joules

2nd cat = mgh = 6 × 10 × 30 = 1800 Joules

You're in an airplane that flies horizontally with speed 1100 km/h (300 m/s ) when an engine falls off. Neglecting air resistanc
Tcecarenko [31]

Answer:

The height of the airplane is 3312.4 meters.

Explanation:

Given that,

Speed of the airplane, v = 1100 km/h = 300 m/s

It takes 26 s for the engine to hit the ground. We need to find the height of the airplane. Using second equation of motion to find it as :

h=ut+\dfrac{1}{2}at^2

Here, u = 0 and a = g

h=\dfrac{1}{2}gt^2\\\\h=\dfrac{1}{2}\times 9.8\times (26)^2\\\\h=3312.4\ m

The height of the airplane is 3312.4 meters.
