Answer:
intensity is 11.0145 W/m^2
Energy is 5.07 J
Explanation:
Given data
amplitude E =91.1 V/m
area = 0.0269 m2
time t = 17.1 s
to find out
intensity and energy
solution
we know intensity formula that is given below
intensity = E(rms)² / (cμ0)
here c is speed of light and μo is permeability of free space
we know these constant value c = 2.99 x 10^8
μo = 1.26 x 10^-6
put all these value and we get intensity
intensity = (91.1/√2)² / (2.99 x 10^8 × 1.26 x 10^-6)
intensity = 4149.605 / 3.7674 x 10^2
intensity is 11.0145 W/m^2
and Energy is calculated by this formula
Energy = intensity × time × area
put all value now here
Energy = 11.0145 × 17.1 × 0.0269
Energy is 5.07 J
Answer:
Increase
Explanation:
If we assume the gas is ideal, then we can use the ideal gas law:
PV = nRT
If V is held constant while P increases, then T will also increase.
convergent and counterclockwise

Answer:
The mass of the planet Newtonia is .
Explanation:
It is given that,
Mass of the bob, m = 1.25 kg
Length of the simple pendulum, l = 185 cm = 1.85 m
Time taken by the simple pendulum, T = 1.42 s
The circumference of Newtonia is measured to be 51,4000 km. The time period of the simple pendulum is given by the formula as:
g is the acceleration due to gravity on planet Newtonia
For one complete cycle, T = 2.84 s
The formula of acceleration due to gravity on any surface is given by :
Since,
So, the mass of the planet Newtonia is . Hence, this is the required solution.
