The time taken is 50 s

Explanation:

For a body moving in uniform motion (= at constant velocity), the velocity of the body is given by:

v=\frac{d}{t}

where

v is the velocity

d is the distance covered

t is the time taken

In this problem, we have a bird travelling with uniform motion. We know that:

v = 8 m/s is the velocity of the bird

d = 400 m is the distance travelled

Solving for t, we find the time the bird needs to cover this distance:

t=\frac{d}{v}=\frac{400}{8}=50 s

Assume you are a perfect blackbody at a temperature of T = 310 K. What is the rate, in watts, at which you radiate energy? (For
madreJ [45]

Answer:

P = 942.54 W

Explanation:

Given:

Temperature, T = 310 K

mass, m = 70 kg

Now from the stefan's law,

we have the formula

P = σAT⁴

where,

P = radiate energy

σ = Stefan's constant = 5.67 × 10⁻⁸ W/(m² K⁴)

A = Area of the body

Average surface area for a human body = 1.8 m²

T = Temperature

on substituting the values we get,

P = 5.67 × 10⁻⁸ × 1.8 × 310⁴

or

P = 942.54 W

A fish inside the water 12cm below the surface looking up through the water sees the outside world contained in a circular horiz
serg [7]

Answer:

13.6 cm

Explanation:

From Snell's law:

n₁ sin θ₁ = n₂ sin θ₂

In the air, n₁ = 1, and light from the horizon forms a 90° angle with the vertical, so sin θ₁ = sin 90° = 1.

Given n₂ = 4/3:

1 = 4/3 sin θ

sin θ = 3/4

If x is the radius of the circle, then sin θ is:

sin θ = x / √(x² + 12²)

sin θ = x / √(x² + 144)

Substituting:

3/4 = x / √(x² + 144)

9/16 = x² / (x² + 144)

9/16 x² + 81 = x²

81 = 7/16 x²

x ≈ 13.6
