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.
Very unlikely. This is not really a good question for Brainly.

Answer:
h = 18.4 cm
Explanation:
Given that,
The speed of the bob at the bottom of the swing is 1.9m/s.
We need to find the initial height of the bob. Let it is h.
We can find it using the conservation of energy i.e.

Where
v is speed of the bob
So,

or
h = 18.4 cm
So, the initial height of the bob is 18.4 cm.
Answer:
The alligator will take t = 10 s to reach the final speed of 35 m/s
Explanation:
As we know that the initial speed of the alligator is 5 m/s
then it accelerate by given acceleration to reach the final speed of 35 m/s
so we will have



now we have
