Answer:

The other bulbs would stay lit.

Explanation:

You're just unscrewing one bulb, not turning off the circuit.

Answer:

The highest pressure is located at points x & y.

Explanation:

The pressure will be greater at the X & y points, because they are at a deeper distance than the Z point. We must remember that the pressure is a function of the depth of the fluid, and is expressed by the following equation.

$P = densi*g*h\\where\\densi = density [kg/m^3]\\g = gravity [m/s^2]\\h = elevation [m]$

The pressure is always measured with respect to the liquid level towards the depth of the fluid, so at greater depth greater pressure

A pulsed proton beam is fired at a target. Each pulse lasts 45.0 ns, and there are protons in each pulse, each proton having a s

skelet666 [1.2K]

Answer:

P = n P₀ 4.9 10¹⁴ Pa

Explanation:

The radiation pressure for full absorption is

P = S / c

Where S the pointing vector, which is equal to the intensity of the beam that is defined as the energy per unit area per unit time

The energy of the protons can be calculated

Em = K = ½ m v²

Area

A = π r²

Intensity is

I = n ½ m v² / π r²

I = ½ n m /π v² / r²

We replace

S = U / t A

S = ½ n m /π v² / r² Δt

The pressure is

P = 1/c (½ n m /π (v / r Δt)²2

Δt = 45 10⁻⁹ s

P = n [½ m /πc (v/r)²] 4.9 10¹⁴

The amount in square brackets is the pressure that a proton creates, which is why it is useful

P = n P₀ 4.9 10¹⁴ Pa

Where Po is the pressure created by a proton

Why do most carnivores live in forest? given reason

kotegsom [21]

$\huge\purple{Hi!}$

most carnivore live in forest because

They are highly dependent on flesh for their food and therefore their food is easily available in forests.
Small animals live in forests that make it the ideal habitat for carnivores.
Carnivores help in maintaining the herbivore population at a healthy level, by hunting.
It all helps in keeping ecosystems in balance.
