For any force and any mass, the acceleration is always

(the strength of the force) divided by (the mass) .

If a force of 5 newtons is applied to a mass of 5 kg, the acceleration will be

(5 Newtons) / (5 kg) = <em>1 m/s²</em>

What are the (time varying) amplitudes of the E and H fields if summer sunlight has an intensity of 1150 W/m2 in any Town?
Archy [21]

Explanation:

Given that,

Intensity = 1150 W/m²

(a). We need to calculate the magnetic field

Using formula of intensity

I=\dfrac{E^2}{2\mu_{0}c}

E=\sqrt{2\times I\mu_{0}c}

Put the value into the formula

E=\sqrt{2\times1150\times4\pi\times10^{-7}\times3\times10^{8}}

E=931.17\ N/C

Using formula of magnetic field

B = \dfrac{E}{c}

Put the value into the formula

B=\dfrac{931.17}{3\times10^{8}}

B=0.0000031039\ T

B=3.10\times10^{-6}\ T

(b). The relative strength of the gravitational and solar electromagnetic pressure forces of the sun on the earth

We need to calculate the gravitational force

Using gravitational force

F=\dfrac{Gm_{s}M_{e}}{r^2}

Put the value into the formula

F=\dfrac{6.67\times10^{-11}\times1.98\times10^{30}\times5.97\times10^{24}}{(1.496\times10^{11})^2}

F=3.522\times10^{22}\ N

We need to calculate the radiation force

Using formula of force

F_{R}=\dfrac{I}{c}\pi\timesR_{E}^{2}

Put the value into the formula

F_{R}=\dfrac{1150}{3\times10^{8}}\times\pi\times(6.378\times10^{6})^2

F_{R}=4.8\times10^{8}\ N

The gravitational and solar electromagnetic pressure forces of the sun on the earth

\dfrac{F_{G}}{F_{R}}=\dfrac{3.522\times10^{22}}{4.8\times10^{8}}

\dfrac{F_{G}}{F_{R}}=7.3375\times10^{13}

Hence, This is the required solution.

How are electromagnetic waves different from ocean waves
nlexa [21]

Answer:

Explanation:

Electromagnetic waves are different from ocean waves through their mode of propagation

Electromagnetic waves are Those waves that do not requires any material medium for their propagation. examples of electromagnetic waves are, Light wave, radiant heat, radio wave,

While

Ocean Waves are classified under mechanical waves, because they required a material medium for the to be to be propagated.

The size of a certain insect population is given by p(t)=200e.02t, where t is measured in days. at what time will the population
AnnyKZ [126]

With the help of the mathematical concept of Functions in physics, the number of days for population to reach 800 will be approximately 69 days.

<h2>What are Functions in physics?</h2>

Functions in physics is a mathematical concept used to represent different types of physical quantities in nature. Some types of functions are- linear, quadratic, cubic, exponential and reciprocal functions. A functions relates a set of inputs with another set of desired outputs. Functions are essential for formulating physical relationships in theoretical and practical sciences. For example, functions can be widely used in the representation of electric and magnetic fields in space and time, they are used in quantum mechanics, it is very widely used in determining the position and motion of an object in space. We perform a variety of mathematical operations on functions to make some conclusions and to answer some typical questions related to a physical system.

Here in this question, we have a function which represents a certain population of insect, the function is given by,

P(t)=200e^0^.^0^2^t

where t represents the number of days.

We have to find the total time in days for the population to reach 800 insects, that means,

P(t)=800

Hence,

200e^0^.^0^2^t=800

e^0^.^0^2^t=\frac{800}{400}

e^0^.^0^2^t=4

Taking natural log both sides

ln e^0^.^0^2^t=ln 4\\

0.02t=ln4

t=\frac{ln4}{0.02}

t=69.3\\

t=69 days (appproximately)
