Answer:

radiation pressure

Explanation:

This is the type of pressure that can be applied on any surface as a result of the exchange of momentum that exists between the object and the electromagnetic field. Radiation pressure generates small amount of forces and cannot be easily noticed although such forces are essential in certain physical processes.

Example is momentum of light or electromagnetic radiation which as any wavelength, in which this wavelength can be absorbed, reflected by matter on any scale.

Answer:

Radiation pressure

Explanation:

Radiation pressure is gotten from the light source. The radiation pressure has a set mass limit of 150 solar masses. Any mass from 150 solar masses or below supports the formation of the stars.

However when the mass exceeds 150 solar masses the force of gravity is unable to hold the masses together and the excess mass

Is usually blown away after which the required mass is then used in the formation.

A plane has an airspeed of 142 m/s. A 30.0 m/s wind is blowing southward at the same time as the plane is flying. What must be t

const2013 [10]

Answer:

$\theta=12.19^{\circ}$

Explanation:

Given that

The speed of the airplane ,v= 142 m/s

The speed of the air ,u = 30 m/s

Lets take angle make by airplane from east direction towards north direction is θ .

Now by using diagram ,we can say that

$sin\theta =\dfrac{u}{v}$

Now by putting the values in the above equation we get

$sin\theta =\dfrac{30}{142}$

$sin\theta=0.21$

$\theta=12.19^{\circ}$

Therefore the angle will be 12.19° .

scoray [572]

Answer: 704

Explanation:Vi = 0 m/s

vf = 65 m/s

a = 3 m/s2

d = ??

vf2 = vi2 + 2*a*d

(65 m/s)2 = (0 m/s)2 + 2*(3 m/s2)*d

4225 m2/s2 = (0 m/s)2 + (6 m/s2)*d

(4225 m 2/m2)/(6 m/s2) = d

d = 704 m
