The mass m of things is known as the lot of material it has. Load is the force that mass is attractive to planet earth or one more object much bigger than it. The relation in between them is

LASIK eye surgery offers pulses the laser irradiate to cut off tissue from the cornea, reshaping it. A typical LASIK laser emits a 1.

143 kW

Explanation:

Given that

Diameter that the beam, d = 1 mm

Wavelength that the beam, λ = 193 nm

Time used by the pulse, t = 14 ns

Energy that the pulse, U = 2 mJ

Recall that Power have the right to be mathematically calculated using the relation,

Power = job-related Done / Time,

To deal with this, we use the formula

P = U / Δt

P = 2*10^-3 J / 14*10^-9 s

P = 142857 W

P = 143 kW



The eastern time zone would certainly the opposite side of the angle made by his car. So this method he would certainly be travel 30cos30 m/s completely in the east direction. Or about 26 m/s in the east direction. 5000 m divided by this lifwynnfoundation.org results in roughly 192 seconds. Ns would usage a calculator to acquire a an ext exact lifwynnfoundation.org

The required elastic potential power is 0.068J

Explanation:

Given,

Spring force constant, k= 3.4 N/M

Spring big length/ Displacement, x= 0.2m

We know,

Elastic potential energy, V=

*

=

*

=

*

=0.068

∴The forced elastic potential energy is 0.068J



A net force of –8750N is offered to stop of 1250.kg auto travelling 25m/s. What braking street is required to bring the vehicle to a hal

lifwynnfoundation.org:

d = 44.64 m

Explanation:

Given that,

Net force acting top top the car, F = -8750 N

The massive of the car, m = 1250 kg

Initial speed of the car, u = 25 m/s

Final speed, v = 0 (it stops)

The formula because that the net force is :

F = ma

a is acceleration the the car

*

Let d be the break distance. It can be calculated using 3rd equation of activity as :

*

So, the required distance spanned by the automobile is 44.64 m.

construct validity

Explanation:

According to my research study on studies performed by assorted psychologists, I can say that based on the information detailed within the question it appears that the researcher is making use of construct validity. This is the act of measure or validating what the extent to i m sorry a claim is true. In this situation due to the fact that the case states that people associated in crimes often tend to perform speed and also drugs, then the researcher compare the criminal responses come those locations to test the validity that the claim.
