Answer:

An ultra intense laser is one with which intensities greater than 1015 W cm-2 can be achieved.

Explanation:

This intensity, which was the upper limit of lasers until the invention of the Chirped Pulse Amplification, CPA technique, is the value around which nonlinear effects on the transport of radiation in materials begin to appear.

Currently, the most powerful lasers reach intensities of the order of 1021W cm-2 and powers of Petawatts, PW, in each pulse. This range of intensities has opened the door for lasers to a multitude of disciplines and scientific areas traditionally reserved for accelerators and nuclear reactors, applying as generators of high-energy electron, ion, neutron and photon beams, without the need for expensive infrastructure.

Answer:

b. as scalpels in surgical procedures.

Explanation:

Lasers are useful in clinicals for soft tissue surgery. It is used to cut, ablate, vaporize, and coagulate. There are several different laser wavelengths used in soft tissue surgery. Different laser wavelengths and device settings (such as pulse duration and power) produce different effects on the tissue.

It focuses a narrow beam and creates high-intensity light. This function; ability to focus very accurately on tiny areas, they can be used for very precise surgical work or for cutting through tissue (in place of a scalpel).

The Earth's escape speed (the speed you need to get away forever) is about 40,000 kilometers per hour. Escape speed depends on t
Anvisha [2.4K]

The Moon s escape speed will be smaller than Earth's.

  • What is escape speed:

The minimum speed that is required for an object to free itself from the gravitational force exerted by a massive object.

The formula of escape speed is

  • v = \sqrt{\frac{2GM}{R} }

where

v is escape velocity

G is universal gravitational constant

M is mass of the body to be escaped from

r is distance from the center of the mass

we can say that,

Escape speed depends on the gravity of the object trying to hold the spacecraft from escaping.

we know that,

The Moon's surface gravity is about 1/6th as powerful or about 1.6 meters per second per second.

since, v ∝ g

The Moon s escape speed will be smaller than Earth's.

How would the force between two charged particles change if one of the charges were to triple in strength (3x stronger)?
Andreyy89

Answer:

The correct option is (d). "3x stronger".

Explanation:

The force between two charged particle is given by :

F=k\dfrac{q_1q_2}{r^2}

If one charge is tripled, q_1'=3q

New force will be :

F'=\dfrac{kq_1'q_2}{r^2}\\\\=3\times F

It means if one of the charges were to triple in strength, then the force will become 3 times of the initial force.

What is the average flow rate in cm3/s of gasoline to the engine of a car traveling at 100 km/h if it averages 10. 0 km/l?
DiKsa [7]

The answer is 2.78 \mathrm{~cm}^{3} / \mathrm{s}

Q=\frac{1 \mathrm{~L}}{10.0 \mathrm{~km}} \times \frac{100 \mathrm{~km}}{\mathrm{~h}} \times \frac{1 \mathrm{~h}}{36005} \times \frac{1000 \mathrm{~cm}^{3}}{\mathrm{~L}}=2.78 \mathrm{~cm}^{3} / \mathrm{s}

Thus, the average flow rate is $2.78 \mathrm{~cm}^{3} / \mathrm{s}$.

What is average flow rate?

  • Average flow, which is often represented in cubic feet per second, refers to the stream's average discharge at a certain location.
  • The flowrate is the rate at which liquid travels through a pipe or into a wellbore from a reservoir.
  • The volume of fluid that moves across a specific cross-sectional area per unit of time is known as the flow rate.
  • It is essential to measure flow rates accurately using the right flowmeters to guarantee that fluid management procedures are efficient, safe, and cost-effective.
