The principle behind how these huge ships are able to float on water

1 answer:

7 0

Answer:

The amount of water it displaces (shaded area ) weighs as much as the ship. The weight of the ship pulling down and the upthrust pushing up are equal and opposite forcers so the ship floats.

Explanation:

Now the weight of the ship is more than the maximum possible upthrust so it sinks to the buttom

A bullet has a mass of 8 grams and a muzzle velocity of 340m/sec. A baseball has a mass of 0.2kg and is thrown by the pitcher at

Thepotemich [5.8K]

Answer:

Momentum of bullet

$P = 2.72 kg m/s$

momentum of baseball

$P = 8 kg m/s$

Explanation:

As we know that momentum is defined as the product of mass and velocity

here we know that

mass of the bullet = 8 gram

velocity of bullet = 340 m/s

momentum of the bullet is given as

$P = mv$

$P = (\frac{8}{1000})(340)$

$P = 2.72 kg m/s$

Now we have

mass of baseball = 0.2 kg

velocity of baseball = 40 m/s[/tex]

momentum of baseball is given as

$P = (0.2)(40)$

$P = 8 kg m/s$

A traveling electromagnetic wave in a vacuum has an electric field amplitude of 72.7 V/m. 72.7 V/m. Calculate the intensity S S

Yakvenalex [24]

Answer:

a) 7.02 W/m²

b) 1.53 J

Explanation:

Given

Amplitude of the electric wave, = 72.7 V/m

Area of flow, A = 0.0211 m²

Time taken, t = 10.3 s

To calculate the Intensity, S. We use the formula

I = E(rms)² / (cμ), where

E(rms) = E / √2 = 72.7 / √2

E(rms) = 72.7 / 1.4142

E(rms) = 51.41

c = 2.99*10^8

μ = 1.26*10^-6

I = 51.41² / [(2.99*10^8) (1.26 x 10^-6)]

I = 2642.99 / 376.74

I = 7.02 W/m²

U = energy = IAt

U = (7.02) * (0.0211) (10.3) J = 1.53 J
