Explanation:
Given that,
Intensity = 1150 W/m²
(a). We need to calculate the magnetic field
Using formula of intensity


Put the value into the formula


Using formula of magnetic field

Put the value into the formula



(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

Put the value into the formula


We need to calculate the radiation force
Using formula of force

Put the value into the formula


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


Hence, This is the required solution.
It will most likely break. The frame is 5 newton's and the string can only hold 2.5 newton's.
03 km west
Explanation:
because from east to west it travelled 4km the from west it travelled 4km back to the origin and 3km from origin to west
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.
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,

where
represents the number of days.
We have to find the total time in days for the population to reach 800 insects, that means,

Hence,



Taking natural log both sides




days (appproximately)
